+
+Released 2019-02-06
+
+## Major Changes
+
+* Rules versioning support: The falco engine and executable now have an *engine version* that represents the fields they support. Similarly, rules files have an optional *required_engine_version: NNN* object that names the minimum engine version required to read that rules file. Any time the engine adds new fields, event sources, etc, the engine version will be incremented, and any time a rules file starts using new fields, event sources, etc, the required engine version will be incremented. [[#492](https://github.com/falcosecurity/falco/pull/492)]
+
+* Allow SSL for K8s audit endpoint/embedded webserver [[#471](https://github.com/falcosecurity/falco/pull/471)]

+
+* Add CII best practices badge. [[#499](https://github.com/falcosecurity/falco/pull/499)]
+
+* Fix kernel module builds when running on centos as a container by installing gcc 5 by hand instead of directly from debian/unstable. [[#501](https://github.com/falcosecurity/falco/pull/501)]
+
+* Mount `/etc` when running as a container, which allows container to build kernel module/ebpf program on COS/Minikube. [[#475](https://github.com/falcosecurity/falco/pull/475)]
+
+* Improved way to specify the source of generic event objects [[#480](https://github.com/falcosecurity/falco/pull/480)]

+
+## v0.13.1
+
+Released 2019-01-16
+
+## Major Changes
+
+
+## Minor Changes

+
+* Fix FPs related to `apt-config`/`apt-cache`, `apk` [[#490](https://github.com/falcosecurity/falco/pull/490)]
+
+* New rules `Launch Package Management Process in Container`, `Netcat Remote Code Execution in Container`, `Lauch Suspicious Network Tool in Container` look for host-level network tools like `netcat`, package management tools like `apt-get`, or network tool binaries being run in a container. [[#490](https://github.com/falcosecurity/falco/pull/490)]
+
+* Fix the `inbound` and `outbound` macros so they work with sendto/recvfrom/sendmsg/recvmsg. [[#470](https://github.com/falcosecurity/falco/pull/470)]

+
+
+## v0.13.0
+
+Released 2018-11-09
+
+## Major Changes
+
+* **Support for K8s Audit Events** : Falco now supports [K8s Audit Events](https://kubernetes.io/docs/tasks/debug-application-cluster/audit/#audit-backends) as a second stream of events in addition to syscalls. For full details on the feature, see the [wiki](https://github.com/falcosecurity/falco/wiki/K8s-Audit-Event-Support).
+
+* Transparent Config/Rule Reloading: On SIGHUP, Falco will now reload all config files/rules files and start processing new events. Allows rules changes without having to restart falco [[#457](https://github.com/falcosecurity/falco/pull/457)] [[#432](https://github.com/falcosecurity/falco/issues/432)]
+

+
+## Rule Changes
+
+* Better coverage (e.g. reduced FPs) for critical stack, hids systems, ufw, cloud-init, etc. [[#445](https://github.com/falcosecurity/falco/pull/445)]
+
+* New rules `Launch Package Management Process in Container`, `Netcat Remote Code Execution in Container`, and `Lauch Suspicious Network Tool in Container` look for running various suspicious programs in a container. [[#461](https://github.com/falcosecurity/falco/pull/461)]
+
+* Misc changes to address false positives in GKE, Istio, etc. [[#455](https://github.com/falcosecurity/falco/pull/455)] [[#439](https://github.com/falcosecurity/falco/issues/439)]
+
+## v0.12.1
+
+Released 2018-09-11
+
+## Bug Fixes

+## v0.12.0
+
+Released 2018-09-11
+
+## Major Changes
+
+* Improved IPv6 Support to fully support use of IPv6 addresses in events, connections and filters [[#sysdig/1204](https://github.com/draios/sysdig/pull/1204)]
+
+* Ability to associate connections with dns names: new filterchecks `fd.*ip.name` allow looking up the DNS name for a connection's IP address. This can be used to identify or restrict connections by dns names e.g. `evt.type=connect and fd.sip.name=github.com`. [[#412](https://github.com/draios/falco/pull/412)] [[#sysdig/1213](https://github.com/draios/sysdig/pull/1213)]
+
+* New filterchecks `user.loginuid` and `user.loginname` can be used to match the login uid, which stays consistent across sudo/su. This can be used to find the actual user running a given process [[#sysdig/1189](https://github.com/draios/sysdig/pull/1189)]
+
+## Minor Changes
+
+* Upgrade zlib to 1.2.11, openssl to 1.0.2n, and libcurl to 7.60.0 to address software vulnerabilities [[#402](https://github.com/draios/falco/pull/402)]
+* New `endswith` operator can be used for suffix matching on strings [[#sysdig/1209](https://github.com/draios/sysdig/pull/1209)]
+
+## Bug Fixes
+
+* Better control of specifying location of lua source code [[#406](https://github.com/draios/falco/pull/406)]
+
+## Rule Changes
+
+* None for this release.
+
+## v0.11.1
+
+Released 2018-07-31
+
+## Bug Fixes
+
+* Fix a problem that caused the kernel module to not load on certain kernel versions [[#397](https://github.com/draios/falco/pull/397)] [[#394](https://github.com/draios/falco/issues/394)]
+
+## v0.11.0
+
+Released 2018-07-24
+
+## Major Changes
+
+* **EBPF Support** (Beta): Falco can now read events via an ebpf program loaded into the kernel instead of the `falco-probe` kernel module. Full docs [here](https://github.com/draios/sysdig/wiki/eBPF-(beta)). [[#365](https://github.com/draios/falco/pull/365)]
+
+## Minor Changes
+
+* Rules may now have an `skip-if-unknown-filter` property. If set to true, a rule will be skipped if its condition/output property refers to a filtercheck (e.g. `fd.some-new-attibute`) that is not present in the current falco version. [[#364](https://github.com/draios/falco/pull/364)] [[#345](https://github.com/draios/falco/issues/345)]
+* Small changes to Falco `COPYING` file so github automatically recognizes license [[#380](https://github.com/draios/falco/pull/380)]
+* New example integration showing how to connect Falco with Anchore to dynamically create falco rules based on negative scan results [[#390](https://github.com/draios/falco/pull/390)]
+* New example integration showing how to connect Falco, [nats](https://nats.io/), and K8s to run flexible "playbooks" based on Falco events [[#389](https://github.com/draios/falco/pull/389)]
+
+## Bug Fixes
+
+* Ensure all rules are enabled by default [[#379](https://github.com/draios/falco/pull/379)]
+* Fix libcurl compilation problems [[#374](https://github.com/draios/falco/pull/374)]
+* Add gcc-6 to docker container, which improves compatibility when building kernel module [[#382](https://github.com/draios/falco/pull/382)] [[#371](https://github.com/draios/falco/issues/371)]
+* Ensure the /lib/modules symlink to /host/lib/modules is set correctly [[#392](https://github.com/draios/falco/issues/392)]
+
+## Rule Changes
+
+* Add additional binary writing programs [[#366](https://github.com/draios/falco/pull/366)]
+* Add additional package management programs [[#388](https://github.com/draios/falco/pull/388)] [[#366](https://github.com/draios/falco/pull/366)]
+* Expand write_below_etc handling for additional programs [[#388](https://github.com/draios/falco/pull/388)] [[#366](https://github.com/draios/falco/pull/366)]
+* Expand set of programs allowed to write to `/etc/pki` [[#388](https://github.com/draios/falco/pull/388)]
+* Expand set of root written directories/files [[#388](https://github.com/draios/falco/pull/388)] [[#366](https://github.com/draios/falco/pull/366)]
+* Let pam-config read sensitive files [[#388](https://github.com/draios/falco/pull/388)]
+* Add additional trusted containers: openshift, datadog, docker ucp agent, gliderlabs logspout [[#388](https://github.com/draios/falco/pull/388)]
+* Let coreos update-ssh-keys write to /home/core/.ssh [[#388](https://github.com/draios/falco/pull/388)]
+* Expand coverage for MS OMS [[#388](https://github.com/draios/falco/issues/388)] [[#387](https://github.com/draios/falco/issues/387)]
+* Expand the set of shell spawning programs [[#366](https://github.com/draios/falco/pull/366)]
+* Add additional mysql programs/directories [[#366](https://github.com/draios/falco/pull/366)]
+* Let program `id` open network connections [[#366](https://github.com/draios/falco/pull/366)]
+* Opt-in rule for protecting tomcat shell spawns [[#366](https://github.com/draios/falco/pull/366)]

-                            Preamble
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
 
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
+   1. Definitions.
 
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-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.
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
 
-  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.
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
 
-  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.
+      "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.
 
-  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.
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
 
-  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.
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
 
-  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.
+      "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.
 
-  The precise terms and conditions for copying, distribution and
-modification follow.
+      "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).
 
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+      "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.
 
-  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".
+      "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."
 
-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.
+      "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.
 
-  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.
+   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.
 
-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.
+   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.
 
-  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:
+   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:
 
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; 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.
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; 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.)
+      (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
 
-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.
+      (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.
 
-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.
+      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.
 
-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.
+   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.
 
-  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:
+   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.
 
-    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,
+   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.
 
-    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,
+   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.
 
-    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.)
+   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.
 
-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.
+   END OF TERMS AND CONDITIONS
 
-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.
+   APPENDIX: How to apply the Apache License to your work.
 
-  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.
+      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.
 
-  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.
+   Copyright [yyyy] [name of copyright owner]
 
-  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.
+   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
 
-  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.
+       http://www.apache.org/licenses/LICENSE-2.0
 
-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.

-

+# Process for becoming a maintainer
+
+* Express interest to the existing maintainers that you or your organization is interested in becoming a
+  maintainer. Becoming a maintainer generally means that you are going to be spending substantial
+  time (>25%) on Falco for the foreseeable future. You should have domain expertise and be extremely
+  proficient in C++. Ultimately your goal is to become a maintainer that will represent your
+  organization.
+* We will expect you to start contributing increasingly complicated PRs, under the guidance
+  of the existing maintainers.
+* We may ask you to do some PRs from our backlog.
+* As you gain experience with the code base and our standards, we will ask you to do code reviews
+  for incoming PRs (i.e., all maintainers are expected to shoulder a proportional share of
+  community reviews).
+* After a period of approximately 2-3 months of working together and making sure we see eye to eye,
+  the existing maintainers will confer and decide whether to grant maintainer status or not.
+  We make no guarantees on the length of time this will take, but 2-3 months is the approximate
+  goal.
+
+## Maintainer responsibilities
+
+* Monitor Slack (delayed response is perfectly acceptable).
+* Triage GitHub issues and perform pull request reviews for other maintainers and the community.
+* During GitHub issue triage, apply all applicable [labels](https://github.com/falcosecurity/falco/labels)
+  to each new issue. Labels are extremely useful for future issue follow up. Which labels to apply
+  is somewhat subjective so just use your best judgment.
+* Make sure that ongoing PRs are moving forward at the right pace or closing them.
+* Participate when called upon in the security releases. Note that although this should be a rare
+  occurrence, if a serious vulnerability is found, the process may take up to several full days of
+  work to implement. This reality should be taken into account when discussing time commitment
+  obligations with employers.
+* In general continue to be willing to spend at least 25% of ones time working on Falco (~1.25
+  business days per week).
+
+## When does a maintainer lose maintainer status
+
+If a maintainer is no longer interested or cannot perform the maintainer duties listed above, they
+should volunteer to be moved to emeritus status. In extreme cases this can also occur by a vote of
+the maintainers per the voting process below.
+
+# Conflict resolution and voting
+
+In general, we prefer that technical issues and maintainer membership are amicably worked out
+between the persons involved. If a dispute cannot be decided independently, the maintainers can be
+called in to decide an issue. If the maintainers themselves cannot decide an issue, the issue will
+be resolved by voting. The voting process is a simple majority in which each senior maintainer
+receives two votes and each normal maintainer receives one vote.
+
+# Adding new projects to the falcosecurity GitHub organization
+
+New projects will be added to the falcosecurity organization via GitHub issue discussion in one of the
+existing projects in the organization. Once sufficient discussion has taken place (~3-5 business
+days but depending on the volume of conversation), the maintainers of *the project where the issue
+was opened* (since different projects in the organization may have different maintainers) will
+decide whether the new project should be added. See the section above on voting if the maintainers
+cannot easily decide.

 ## 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.
+Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Powered by [sysdig’s](https://github.com/draios/sysdig) 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.
+
+Falco is hosted by the Cloud Native Computing Foundation (CNCF) as a sandbox level project. If you are an organization that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details read the [Falco CNCF project proposal](https://github.com/cncf/toc/tree/master/proposals/falco.adoc).
 
 #### What kind of behaviors can Falco detect?
 
-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:
+Falco can detect and alert on any behavior that involves making Linux system calls. Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process. For example, Falco can easily detect incidents including but not limited to:
 
-- 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

-#### How Falco Compares to Other Security Tools like SELinux, Auditd, etc.
+#### How do you compare Falco with other security tools?
 
-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.

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.

+
+## Instructions for Kubernetes 1.11
+
+The main steps are:
+
+1. Deploy Falco to your Kubernetes cluster
+1. Define your audit policy and webhook configuration
+1. Restart the API Server to enable Audit Logging
+1. Observe Kubernetes audit events at falco
+
+### Deploy Falco to your Kubernetes cluster
+
+Follow the [Kubernetes Using Daemonset](../../integrations/k8s-using-daemonset/README.md) instructions to create a falco service account, service, configmap, and daemonset.
+
+### Define your audit policy and webhook configuration
+
+The files in this directory can be used to configure Kubernetes audit logging. The relevant files are:
+
+* [audit-policy.yaml](./audit-policy.yaml): The Kubernetes audit log configuration we used to create the rules in [k8s_audit_rules.yaml](../../rules/k8s_audit_rules.yaml).
+* [webhook-config.yaml.in](./webhook-config.yaml.in): A (templated) webhook configuration that sends audit events to an ip associated with the falco service, port 8765. It is templated in that the *actual* IP is defined in an environment variable `FALCO_SERVICE_CLUSTERIP`, which can be plugged in using a program like `envsubst`.
+
+Run the following to fill in the template file with the `ClusterIP` IP address you created with the `falco-service` service above. Although services like `falco-service.default.svc.cluster.local` can not be resolved from the kube-apiserver container within the minikube vm (they're run as pods but not *really* a part of the cluster), the `ClusterIP`s associated with those services are routable.
+
+```
+FALCO_SERVICE_CLUSTERIP=$(kubectl get service falco-service -o=jsonpath={.spec.clusterIP}) envsubst < webhook-config.yaml.in > webhook-config.yaml
+```
+
+### Restart the API Server to enable Audit Logging
+
+A script [enable-k8s-audit.sh](./enable-k8s-audit.sh) performs the necessary steps of enabling audit log support for the apiserver, including copying the audit policy/webhook files to the apiserver machine, modifying the apiserver command line to add `--audit-log-path`, `--audit-policy-file`, etc. arguments, etc. (For minikube, ideally you'd be able to pass all these options directly on the `minikube start` command line, but manual patching is necessary. See [this issue](https://github.com/kubernetes/minikube/issues/2741) for more details.)
+
+It is run as `bash ./enable-k8s-audit.sh <variant> static`. `<variant>` can be one of the following:
+
+* `minikube`
+* `kops`
+
+When running with `variant` equal to `kops`, you must either modify the script to specify the kops apiserver hostname or set it via the environment: `APISERVER_HOST=api.my-kops-cluster.com bash ./enable-k8s-audit.sh kops`
+
+Its output looks like this:
+
+```
+$ bash enable-k8s-audit.sh minikube static

+
+Kubernetes audit events will then be routed to the falco daemonset within the cluster, which you can observe via `kubectl logs -f $(kubectl get pods -l app=falco-example -o jsonpath={.items[0].metadata.name})`.
+
+## Instructions for Kubernetes 1.13
+
+The main steps are:
+
+1. Deploy Falco to your Kubernetes cluster
+2. Restart the API Server to enable Audit Logging
+3. Deploy the AuditSink object for your audit policy and webhook configuration
+4. Observe Kubernetes audit events at falco
+
+### Deploy Falco to your Kubernetes cluster
+
+Follow the [Kubernetes Using Daemonset](../../integrations/k8s-using-daemonset/README.md) instructions to create a Falco service account, service, configmap, and daemonset.
+
+### Restart the API Server to enable Audit Logging
+
+A script [enable-k8s-audit.sh](./enable-k8s-audit.sh) performs the necessary steps of enabling dynamic audit support for the apiserver by modifying the apiserver command line to add `--audit-dynamic-configuration`, `--feature-gates=DynamicAuditing=true`, etc. arguments, etc. (For minikube, ideally you'd be able to pass all these options directly on the `minikube start` command line, but manual patching is necessary. See [this issue](https://github.com/kubernetes/minikube/issues/2741) for more details.)

+***Done!
+$
+```
+
+### Deploy AuditSink objects
+
+[audit-sink.yaml.in](./audit-sink.yaml.in), in this directory, is a template audit sink configuration that defines the dynamic audit policy and webhook to route Kubernetes audit events to Falco.
+
+Run the following to fill in the template file with the `ClusterIP` IP address you created with the `falco-service` service above. Although services like `falco-service.default.svc.cluster.local` can not be resolved from the kube-apiserver container within the minikube vm (they're run as pods but not *really* a part of the cluster), the ClusterIPs associated with those services are routable.
+
+```
+FALCO_SERVICE_CLUSTERIP=$(kubectl get service falco-service -o=jsonpath={.spec.clusterIP}) envsubst < audit-sink.yaml.in > audit-sink.yaml
+```
+
+### Observe Kubernetes audit events at falco
+
+Kubernetes audit events will then be routed to the falco daemonset within the cluster, which you can observe via `kubectl logs -f $(kubectl get pods -l app=falco-example -o jsonpath={.items[0].metadata.name})`.
+
+## Instructions for Kubernetes 1.13 with dynamic webhook and local log file
+
+If you want to use a mix of `AuditSink` for remote audit events as well as a local audit log file, you can run `enable-k8s-audit.sh` with the `"dynamic+log"` argument e.g. `bash ./enable-k8s-audit.sh <variant> dynamic+log`. This will enable dynamic audit logs as well as a static audit log to a local file. Its output looks like this:
+
+```
+***Copying apiserver config patch script to apiserver...
+apiserver-config.patch.sh                                                                          100% 2211   662.9KB/s   00:00

+***Modifying k8s apiserver config (will result in apiserver restarting)...
+***Done!
+```
+
+The audit log will be available on the apiserver host at `/var/lib/k8s_audit/audit.log`.

+# Create Falco rule from Anchore policy result
+
+This integration creates a rule for Sysdig Falco based on Anchore policy result.
+So that when we will try to run an image which has a ```stop``` final action result
+in Anchore, Falco will alert us.
+
+## Getting started
+
+### Prerequisites
+
+For running this integration you will need:
+
+* Python 3.6
+* pipenv
+* An [anchore-engine](https://github.com/anchore/anchore-engine) running
+
+### Configuration
+
+This integration uses the [same environment variables that anchore-cli](https://github.com/anchore/anchore-cli#configuring-the-anchore-cli):
+
+* ANCHORE_CLI_USER: The user used to conect to anchore-engine. By default is ```admin```
+* ANCHORE_CLI_PASS: The password used to connect to anchore-engine.
+* ANCHORE_CLI_URL: The url where anchore-engine listens. Make sure does not end with a slash. By default is ```http://localhost:8228/v1```
+* ANCHORE_CLI_SSL_VERIFY: Flag for enabling if HTTP client verifies SSL. By default is ```true```
+
+### Running
+
+This is a Python program which generates a Falco rule based on anchore-engine
+information:
+
+```
+pipenv run python main.py
+```
+
+And this will output something like:
+
+
+```yaml
+- macro: anchore_stop_policy_evaluation_containers
+  condition: container.image.id in ("8626492fecd368469e92258dfcafe055f636cb9cbc321a5865a98a0a6c99b8dd", "e86d9bb526efa0b0401189d8df6e3856d0320a3d20045c87b4e49c8a8bdb22c1")
+
+- rule: Run Anchore Containers with Stop Policy Evaluation
+  desc: Detect containers which does not receive a positive Policy Evaluation from Anchore Engine.
+
+  condition: evt.type=execve and proc.vpid=1 and container and anchore_stop_policy_evaluation_containers
+  output: A stop policy evaluation container from anchore has started (%container.info image=%container.image)
+  priority: INFO
+  tags: [container]
+```
+
+You can save that output to ```/etc/falco/rules.d/anchore-integration-rules.yaml```
+and Falco will start checking this rule.
+
+As long as information in anchore-engine can change, it's a good idea to run this
+integration **periodically** and keep the rule synchronized with anchore-engine
+policy evaluation result.
+
+## Tests
+
+As long as there are contract tests with anchore-engine, it needs a working
+anchore-engine and its environment variables.
+
+```
+pipenv install -d
+pipenv run mamba --format=documentation
+```
+
+## Docker support
+
+### Build the image
+
+```
+docker build -t sysdig/anchore-falco .
+```
+
+### Running the image
+
+An image exists on DockerHub, its name is ```sysdig/anchore-falco```.
+
+So you can run directly with Docker:
+
+```
+docker run --rm -e ANCHORE_CLI_USER=<user-for-custom-anchore-engine> \
+                -e ANCHORE_CLI_PASS=<passsword-for-user-for-custom-anchore-engine> \
+                -e ANCHORE_CLI_URL=http://<custom-anchore-engine-host>:8228/v1 \
+                sysdig/anchore-falco
+```
+
+And this will output the Falco rule based on *custom-anchore-engine-host*.

 If you are running Kubernetes with Legacy Authorization enabled, you can use `kubectl` to deploy the Daemon Set provided in the `k8s-without-rbac` directory. The example provides the ability to post messages to a Slack channel via a webhook. For more information on getting a webhook URL for your Slack team, refer to the [Slack documentation](https://api.slack.com/incoming-webhooks). Modify the [`args`](https://github.com/draios/falco/blob/dev/examples/k8s-using-daemonset/falco-daemonset.yaml#L21) passed to the Falco container to point to the appropriate URL for your webhook.

 #### What kind of behaviors can Falco detect?
 
-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.
