a bug in GLIBC (https://sourceware.org/bugzilla/show_bug.cgi?id=28257).

## v0.37.0
Released on 2024-01-30
### Breaking Changes
- The deprecated `rate-limiter` mechanism is removed as it is no longer used.
- the deprecated `outputs.rate` Falco config is removed.
- the deprecated `outputs.max_burst` Falco config is removed.
- The deprecated `--userspace` CLI option is removed as it is no longer used.
- The `falco-driver-loader` script will be removed and embedded into falcoctl. The new falcoctl driven implementation will drop:
- `--source-only` CLI option.
- `BPF_USE_LOCAL_KERNEL_SOURCES` environment variable.
- `DRIVER_CURL_OPTIONS` environment variable.
- `FALCO_BPF_PROBE` environment variable is not used by the new falcoctl driver loader, since it is already deprecated and will be removed in the next major version.
Some env vars were renamed:
- `DRIVERS_REPO` env variable has been replaced by `FALCOCTL_DRIVER_NAME` or `--name` command line argument for `falcoctl driver` command
- `DRIVERS_NAME` env variable has been replaced by `FALCOCTL_DRIVER_REPOS`, or `--repo` command line argument for `falcoctl driver` command
- `DRIVER_KERNEL_RELEASE` env variable has been replaced by `--kernelrelease` command line argument for `falcoctl driver install` command
- `DRIVER_KERNEL_VERSION` env variable has been replaced by `--kernelversion` command line argument for `falcoctl driver install` command
- `DRIVER_INSECURE_DOWNLOAD` env variable has been replaced by `--http-insecure` command line argument for `falcoctl driver install` command
- Remove `-K/-k` options from Falco in favor of the new `k8smeta` plugin.
- Drop plugins shipped with Falco since plugins are now be managed by falcoctl.
- Falco 0.37.0 allows environment variables to be expanded even if they are part of a string. This introduces small breaking changes:
- Previously, environment variables used in YAML that were empty or defined as `“”` would be expanded to the default value. This was not consistent with the way YAML was handled in other cases, where we only returned the default values if the node was not defined. Now expanded env vars retain the same behavior of all other variables.
- Falco 0.37.0 will return default value for nodes that cannot be parsed to chosen type.
- `program_output` command will be env-expanded at init time, instead of letting `popen` and thus the `sh` shell expand it. This is technically a breaking change even if no behavioral change is expected. Also, you can avoid env var expansion by using `${{FOO}}` instead of `${FOO}`. It will resolve to `${FOO}` and won't be resolved to the env var value.

# How to contribute
## Enforce coding style 💻
### Introduction
This document introduces the coding style that will be applied in this repository.
This coding style involves all the following files: `.c`, `.h`, `.cpp`, `.cmake`, `CMakeLists.txt`. To enforce it we rely on two main tools:
1. `clang-format` version `18.1.8`.
2. `cmake-format` version `0.6.13`.
> __Please note__: tools versions are important! Different versions will enforce slightly different changes on the code. For example `clang-format-18` will produce a slightly different output respect to `clang-format-17` always respecting the imposed style.
The coding style is expressed through the 2 configuration file that you find in this repo: `.clang-format`, `.cmake-format.json`.
### Enforce the style locally
There are many ways to enforce the style locally, here we will describe two of them:
1. Use `pre-commit` framework.
2. Use the repo `Makefile`.
#### 1.Pre-commit framework (suggested if you don't have the 2 tools already installed on your machine)
The `pre-commit` framework allows you to automatically install different `git-hooks` that will run at every new commit. More precisely, if you use the `.pre-commit-config.yaml` in this repo you will install 3 different hooks:
1. The `clang-format` hook: this is a `pre-commit` git hook that runs `clang-format` on your staged changes.
2. The `cmake-format` hook: this is a `pre-commit` git hook that runs `cmake-format` on your staged changes.
3. The `DCO signed-off` hook: this is a `pre-commit-msg` git hook that adds the `DCO` on your commit if not present. This hook is not strictly related to the coding style so we will talk about it in a separate section: [Add DCO signed-off to your commits](#add-dco-signed-off-to-your-commits).
Now let's see what we need to use `pre-commit` framework.
##### Step 1
Install `pre-commit` framework following the [official documentation](https://pre-commit.com/#installation).
> __Please note__: you have to follow only the "Installation" section.
##### Step 2
Once you have installed `pre-commit`, you don't need to install anything else! This is the good point of using a framework like `pre-commit`, all the tools necessary to format your code will be directly managed by the framework. But in order to be ready, you need to install the git hooks in your local repo.
This simple command allows you to install the two `pre-commit` git hooks, `clang-format` and `cmake-format`.
```bash
pre-commit install --install-hooks --hook-type pre-commit --overwrite
```
If you want to install also the `pre-commit-msg` git hook for the DCO you have to type the following command, but be sure to have configured all you need as said in the [dedicated section]((#add-dco-signed-off-to-your-commits))
```bash
pre-commit install --install-hooks --hook-type prepare-commit-msg --overwrite
```
You have done, at every new commit, this hook will check that your patch respects the coding style of this repo!
If you want to detach the git hooks, you can simply type:
```bash
pre-commit uninstall --hook-type prepare-commit-msg
pre-commit uninstall --hook-type pre-commit
```
#### 2.Makefile
##### Step 1
In order to use the repo `Makefile`, you need to install on your local machine the two aforementioned tools:
__clang-format v18.1.8__
One of the easiest ways to install `clang-format` could be directly downloading its static binary from [here](https://github.com/muttleyxd/clang-tools-static-binaries).
There are other ways for example you can download the package for your distro or you can also build it from sources.
__cmake-format v0.6.13__
To install `cmake-format` you can follow the official documentation [here](https://cmake-format.readthedocs.io/en/latest/installation.html).
> __NOTE__: Please check the versions of the two tool with `clang-format --version` and `cmake-format --version`.
##### Step 2
Once you have installed the __right__ versions of the 2 tools, you can simply type `make format-all` from the root directory of the project (`/libs`) to format all your code according to the coding style.
Remember to do that before submitting a new patch upstream! 😁
#### Other solutions
Obviously, you can also install the 2 tools locally and enable some extension of your favorite IDE (like `VScode`) to format your code every time you save your files!
## Add DCO signed-off to your commits 🔏
### Introduction
Another requirement for contributing to the `libs` repository, is applying the [DCO](https://cert-manager.io/docs/contributing/sign-off/) to every commit you want to push upstream.
Before doing this you have to configure your git user `name` and `email` if you haven't already done it. To check your actual `name` and `email` type:
```bash
git config --get user.name
git config --get user.email
```
If they are correct you have done, otherwise, you have to set them:
```bash
git config user.name <full-name>
git config user.email <mail-used_with-GitHub-profile>
```
>__Please note__: If you have problems in doing this you can read the full documentation [here](https://docs.github.com/en/get-started/getting-started-with-git/setting-your-username-in-git).
### Enforce the DCO locally
Now you are ready to sign your commits! You have two main ways to do this:
1. Manually with `git` tool.
2. Use the `pre-commit-msg` hook quoted before.
### Manually
To do this you just need to remember the `-s` while performing your commits:
```bash
git commit -s
```
or with the inline message:
```bash
git commit -s -m "my first commit"
```
### Use `pre-commit` hook
Here if you have already added the hook in the [previous section](#step-2), you have to do nothing otherwise you have to simply install the DCO hook with:
```bash
pre-commit install --install-hooks --hook-type prepare-commit-msg --overwrite
```
And you have done! Now you don't have to remember the `-s` option every time you commit something, the DCO hook will automatically add the DCO if you forget it! 😄
## Some best practices 📏
### Class variables
To know whether a variable belongs to a `class` or a `function`, we start member variables with `m_`.
Example:
```c
public int32_t m_counter;
```
### Global variables
To know whether the variable is global or not, we start globals with `g_`.
Example:
```c
int g_nplugins;
```
### Capitalization
The naming convention is camel-cased "Unix" style, i.e. always lower case. Words are separated by underscores.
Example:
```c
int32_t g_global_bean_counter;
int32_t count_beans();
```
and not,
```c
int32_t GlobalBeanCounter;
int32_t CountBeans();
```
### Packed Structures
Packed structures should use the GCC and MSVC-style supported `pragma`:
Example:
```c
#pragma pack(push,1)
struct frame_control
{
struct fields....
};
#pragma pack(pop)
```
### 64-bit constants
Put an `LL` at the end of your `64-bit` constants. Without the `LL`, some platform compilers try to interpret the constant on the right-hand side as a `long integer` instead of a `long long` and this could lead to an error at building time.
Example:
```c
x=0X00FF00000000000LL
```

The Falco Project codebase is maintained under the [falcosecurity GitHub organization](https://github.com/falcosecurity). The primary repository, [falcosecurity/falco](https://github.com/falcosecurity/falco), holds the source code for the Falco binary, while other sub-projects are hosted in dedicated repositories. This approach of isolating components into specialized repositories enhances modularity and focused development. Notable [core repositories](https://github.com/falcosecurity/evolution?tab=readme-ov-file#core) include:
This is the main Falco repository which contains the source code for building the Falco binary. By utilizing its [libraries](https://github.com/falcosecurity/libs) and the [falco.yaml](falco.yaml) configuration file, this repository forms the foundation of Falco's functionality. The Falco repository is closely interconnected with the following *core* repositories:
- [falcosecurity/libs](https://github.com/falcosecurity/libs): This repository hosts Falco's core libraries, which constitute the majority of the binarys source code and provide essential features, such as kernel drivers.
- [falcosecurity/rules](https://github.com/falcosecurity/rules): It contains the official ruleset for Falco, offering pre-defined detection rules for various security threats and abnormal behaviors.
- [falcosecurity/plugins](https://github.com/falcosecurity/plugins): This repository supports integration with external services through plugins that extend Falco's capabilities beyond syscalls and container events, with plans for evolving specialized functionalities in future releases.
- [falcosecurity/falcoctl](https://github.com/falcosecurity/falcoctl): A command-line utility designed for managing and interacting with Falco.
- [falcosecurity/charts](https://github.com/falcosecurity/charts): This repository provides Helm charts for deploying Falco and its ecosystem, simplifying the installation and management process.
- [falcosecurity/libs](https://github.com/falcosecurity/libs): Falco's libraries are key to its fundamental operations, making up the greater portion of the source code of the Falco binary and providing essential features such as kernel drivers.
- [falcosecurity/rules](https://github.com/falcosecurity/rules): Contains the official ruleset for Falco, providing pre-defined detection rules for various security threats and abnormal behaviors.
- [falcosecurity/plugins](https://github.com/falcosecurity/plugins/): Falco plugins facilitate integration with external services, expand Falco's capabilities beyond syscalls and container events, and are designed to evolve with specialized functionality in future releases.
- [falcosecurity/falcoctl](https://github.com/falcosecurity/falcoctl): Command-line utility for managing and interacting with Falco.

## Getting Started with Falco
If you're new to Falco, begin your journey with our [Getting Started](https://falco.org/docs/getting-started/) guide. For production deployments, please refer to our comprehensive [Setup](https://falco.org/docs/setup/) documentation.
Carefully review and follow the [official guide and documentation](https://falco.org/docs/getting-started/).
As final recommendations before deploying Falco, verify environment compatibility, define your detection goals, optimize performance, choose the appropriate build, and plan for SIEM or data lake integration to ensure effective incident response.
Considerations and guidance for Falco adopters:
### Demo Environment
1. Understand dependencies: Assess the environment where you'll run Falco and consider kernel versions and architectures.
A demo environment is provided via a docker-compose file that can be started on a docker host which includes falco, falcosidekick, falcosidekick-ui and its required redis database. For more information see the [docker-compose section](docker/docker-compose/)
2. Define threat detection objectives: Clearly identify the threats you want to detect and evaluate Falco's strengths and limitations.
3. Consider performance and cost: Assess compute performance overhead and align with system administrators or SREs. Budget accordingly.
4. Choose build and customization approach: Decide between the open source Falco build or creating a custom build pipeline. Customize the build and deployment process as necessary, including incorporating unique tests or approaches, to ensure a resilient deployment with fast deployment cycles.
5. Integrate with output destinations: Integrate Falco with SIEM, data lake systems, or other preferred output destinations to establish a robust foundation for comprehensive data analysis and enable effective incident response workflows.

Falco's [Build Falco from source](https://falco.org/docs/developer-guide/source/) is the go-to resource to understand how to build Falco from source. In addition, the [falcosecurity/libs](https://github.com/falcosecurity/libs) repository offers additional valuable information about tests and debugging of Falco's underlying libraries and kernel drivers.
Here's an example of a `cmake` command that will enable everything you need for all unit tests of this repository:
```bash
cmake \
-DUSE_BUNDLED_DEPS=ON \
-DBUILD_LIBSCAP_GVISOR=ON \
-DBUILD_BPF=ON \
-DBUILD_DRIVER=ON \
-DBUILD_FALCO_MODERN_BPF=ON \
-DCREATE_TEST_TARGETS=ON \
-DBUILD_FALCO_UNIT_TESTS=ON ..;
```
Build and run the unit test suite:
```bash
nproc=$(grep processor /proc/cpuinfo | tail -n 1 | awk '{print $3}');
make -j$(($nproc-1)) falco_unit_tests;
# Run the tests
sudo ./unit_tests/falco_unit_tests;
```
Optionally, build the driver of your choice and test run the Falco binary to perform manual tests.
Lastly, The Falco Project has moved its Falco regression tests to [falcosecurity/testing](https://github.com/falcosecurity/testing).

## FAQs
### Why is Falco in C++ rather than Go or {language}?
<details>
<summary>Expand Information</summary>
## Why is Falco in C++ rather than Go or {language}?
1. The first lines of code at the base of Falco were written some time ago, where Go didn't yet have the same level of maturity and adoption as today.
2. The Falco execution model is sequential and mono-thread due to the statefulness requirements of the tool, and so most of the concurrency-related selling points of the Go runtime would not be leveraged at all.
@@ -122,16 +89,6 @@ Please refer to the [Contributing](https://github.com/falcosecurity/.github/blob
9. Memory safety is definitely a concern and we try our best to keep an high level of quality even though C++ is quite error prone. For instance, we try to use smart pointers whenever possible, we build the libraries with an address sanitizer in our CI, we run Falco through Valgrind before each release, and have ways to stress-test it to detect performance regressions or weird memory usage (e.g. https://github.com/falcosecurity/event-generator). On top of that, we also have third parties auditing the codebase by time to time. None of this make a perfect safety standpoint of course, but we try to maximize our odds. Go would definitely make our life easier from this perspective, however the tradeoffs never made it worth it so far due to the points above.
10. The C++ codebase of falcosecurity/libs, which is at the core of Falco, is quite large and complex. Porting all that code to another language would be a major effort requiring lots of development resource and with an high chance of failure and regression. As such, our approach so far has been to choose refactors and code polishing instead, up until we'll reach an optimal level of stability, quality, and modularity, on that portion of code. This would allow further developments to be smoother and more feasibile in the future.

* We use `modern-falco-builder.Dockerfile` to build Falco with the modern probe and return it as a Dockerfile output. This Dockerfile doesn't generate a Docker image but returns as output (through the `--output` command):
* Falco `tar.gz`.
* Falco `deb` package.

# On Host Anomaly Detection Framework - New `anomalydetection` Plugin
## Motivation
**A Wind of Change for Threat Detection**
Feel that light breeze? That is the continued advancement of cloud native security blowing steady. But despite our progress, threat actors are outpacing our innovation constantly finding new ways to thwart and tornado past our achievements — rule-based detections focus on what we *think* attackers will do, not on what they *are* doing and generate enough alerts to bury security analysts in a sandstorm of poor signal-to-noise. Can this dynamic be blown back to shift the information asymmetry in favor of defenders?
This framework lays the foundation on how to create high-value, kernel signals that are difficult to bypass - but not in the traditional way. Advanced data analytics is an emerging crosswind that enables us to soar past attackers by detecting deviations in current behavior from past behavior.
## Benefits to the Ecosystem
Advanced data analytics enables us to combine the intricacies of the Linux kernel with on-host anomaly detection in cloud native and cloud environments to determine patterns of past behavior in running applications. By detecting deviations in current behavior from past behavior, we can shift the focus away from relying solely on signatures and rule matching to catch attackers.
Threat detection in open source and more importantly cloud native is constrained by the amount of rules we can write and the signatures we know to look for in our environments. But these have the same problem: they assume our attackers don't change what they're doing. The reality is attackers are not limited to the ways, means, and methods they employ to expose, manipulate, or even destroy our data, systems, and organizations.
This framework leverages an attacker's mindset applied to detection engineering: observing and learning about our targets to create more rich and actionable alerts so we can catch them earlier and more often - regardless if it's behavior we know about, or something we haven't seen yet.
## Elevator Pitch
When Falco processes events in userspace, its rules engine filters the events while the parsers simultaneously update and maintain an internal state. This state includes a process tree cache that enhances Falco alerts by providing contextual information derived from previous events. The goal is to enhance the "state engine" even further and provide an option for monitoring the behavior of applications over time.
To achieve this, end users define a "behavior profile" in the configuration by combining existing event fields such as process name, file descriptor (fd), executable path, parent lineage, cmdline, and others. During event parsing on the hot path, Falco compresses and stores this information in a "filter" - an efficient probabilistic data structure that optimizes space, time, robustness and accuracy. As time progresses, Falco provides more accurate estimates of application behavior counts and identifies events as rare or heavy hitters. Instead of analyzing the original event stream, you can write Falco rules based on pre-filtered data.
This approach introduces a novel threat detection framework that analyzes abnormal application behavior in real-time, derived and observed in a data-driven fashion, without requiring operator reconfiguration of Falco. It complements the operator's expertise and extends capabilities similar to our current practices. The new capability draws inspiration from big data stream and database query optimizations, ensuring that Falco maintains a streamlined real-time one-pass stream with zero allocations.
Similar to Falco rules, the analysis of events may require multiple behavior profiles of different dimensions based on sets of events. These profiles can either vote in parallel or in a cascading fashion, a common practice in established algorithms. This is just the beginning and and paves the way for more sophisticated approaches, such as running Falco in a DAST-like capacity to build a pre-state pattern file on a workload with test data and soften the cold-start via distributing it to production.
## Challenges and Considerations
First, The Falco Project is committed to continuously ensuring access to the most accurate data possible for on-host threat detection. As an example, recent efforts involved expanding kernel signal logging, such as verifying if an execve call is linked to a file descriptor existing exclusively in memory or improving the efficient and reliable resolution of symlinks for executable paths. Therefore, the proposed anomaly detection framework operates under the assumption of having the *correct* data, thereby complementing the ongoing efforts to expand logging coverage and improve its quality. In summary, the primary focus of the framework is to derive increased value from the existing *right* data that is currently available.
There is a common perception that attacks on running cloud applications, as well as their indicators of compromise, are typically rare when the appropriate data or combination of signals is considered. While this holds true, there are inherent challenges in applying this concept of rarity to robust data analytics approaches.
On the one hand, this is due to the diverse range of attacks and attack vectors. An attacker may introduce a new malicious binary (which is comparatively easier to detect using traditional rules and high-value kernel signals) after gaining initial access. Alternatively, they may exploit existing binaries, shell built-ins, and employ obfuscation techniques to "live off the land". The Turing completeness of the latter scenario, in particular, leads to an infinite number of attack possibilities.
However, what poses even more challenges in anomaly detection lies not necessarily in the nature of attacks but rather in identifying the right signals and their appropriate combinations for robust analytics to distinguish between normal and anomalous behavior. This challenge becomes particularly evident when considering the natural fluctuations in application behavior over time and the occurrence of ad-hoc legitimate debugging activities. Such fluctuations can arise from various factors, including routine deployment updates. Moreover, certain applications may produce random file names or execute arbitrary executable paths as part of their regular operations, adding to the challenge of anomaly detection. This is compounded by the inherent "cold start" issue when initially observing an application. In such cases, the algorithms must demonstrate flexibility and robustness by recognizing and encoding consistent patterns, similar to how humans can identify the sameness by examining combinations of file names, command arguments, parent process lineage, and other attributes. Furthermore, factors like data inconsistency and the diverse forms of data representations (comprising a mix of numeric data and strings with varying meanings) further complicate the task.
We believe it is important to incorporate operator heuristics or domain knowledge into the algorithm's definition of rarity. For example, while current algorithms are capable of generating human faces, they used to frequently produce images with different eye colors. However, if we were to inform the machine that humans typically have matching eye colors, it could easily correct this discrepancy. This highlights the role of the security engineer as a guiding hand to the algorithms, both in terms of handling noise tolerance and choosing the appropriate data to be ingested into the algorithm. This is crucial as machines are currently limited in their ability to draw meaningful observations from limited data and constrained memory. In summary, this is where the fusion of data-driven anomaly detection and rules matching will come into play.
Lastly, the value proposition of conducting real-time anomaly analysis on the host lies in the unique options it offers, which cannot be achieved through alternative methods. On the host, we can observe anomalies based on all relevant and observed kernel events. In contrast, sending a large volume of kernel events to a centralized system would be impractical, resulting in significant costs for data pipeline management and data lake compute expenses.
## Initial Scope
The initial scope is to implement the Count Min Sketch algorithm using n shared sketches and expose its count estimates as new filterchecks for use in Falco rules. An MVP can be explored in this libs draft PR [wip: new(userspace/libsinsp): MVP CountMinSketch Powered Probabilistic Counting and Filtering](https://github.com/falcosecurity/libs/pull/1453). Moreover, the initial anomaly detection framework will include a transparent `plugin` user interface for defining application behavior profiles and utilizing sketch count estimates in Falco rules. The primary direct benefit lies in establishing a safety boundary for Falco rules in production environments, allowing for broader rule monitoring while preventing Falco rules from blowing up in production.
Furthermore, The Falco Project will provide adopters with valuable initial use cases, recommended thresholds, and callouts for known issues. One important consideration is the identification of SRE anti-patterns. Another consideration is to provide *very clear* guidance to adopters for setting and configuring parameters, including recommended minimums. Additionally, guidance should be provided on indicators to look for in order to determine if adjustments need to be made and in which direction, particularly when defining application behavior profiles.
## High-Level Technical Design of a New `anomalydetection` Plugin
This document provides a high-level proposal with limited technical details.
*Probabilistic Data Structures*
One option for implementing the probabilistic filter is by utilizing a robust two-dimensional probabilistic data structure known as the Count Min Sketch. This data structure is widely employed in distributed stream processing frameworks such as Apache Spark, Apache Storm, Apache Flink, and others, as well as databases like Redis and PostgreSQL.
Technical details and implications are extensively covered in numerous research papers and textbooks. Therefore, here are some key points to consider in order to make informed choices:
- The challenges posed by both hard and soft collisions can be mitigated by using multiple non-cryptographic hash functions, which has been mathematically proven to be effective.
- Despite providing one-sided error bounds and preventing undercounting, the sketchy data structure requires adopters to define a tolerance level for overcounting. This tolerance level determines what qualifies as rare or noteworthy.
- To enhance accuracy and reduce estimation errors, consider debiasing data (e.g. Count Min Sketch with Conservative Updates) or applying a logarithmic scale to address kernel event data skew. The logarithmic scale may suit threat detection, targeting low-frequency or long-tail attack-related items. However, only use if performance overhead is acceptable.
- Use larger shared sketches and incorporate container IDs as part of the behavior profiles to differentiate between workloads / applications. Conversely, use separate sketches for distinct behavior profiles, also known as the "what we are counting".
- ... and numerous other aspects that will be discussed in subsequent implementation PRs.
*Plumbing and Interface*
The ultimate goal is to introduce these new capabilities as plugin. A significant amount of work will be dedicated to addressing the necessary plumbing required to support the new framework and integrate it with the existing rules filtering, `libsinsp` and `plugin` mechanisms. This integration aims to provide a user-friendly interface that allows users to easily configure and utilize the opt-in framework for different use cases.
For instance, the interface should empower end users to define error tolerances and, consequently, sketch dimensions, along with other tuning parameters, bounds, and settings. Ultimately, it should enable the definition of n behavior profiles to facilitate the use of count estimates in Falco rules.
## What this Framework is Not
- This framework is not intended to function as an event aggregator or enhancer, such as netflow data. Its sole purpose is to serve as an anomaly filter for individual events, utilizing the existing sinsp state, the newly built state through sketches, and the current rules engine.
- The development of this framework will not be swayed by overly specific use cases that limit its broader adoption and coverage.
- While it may not offer flawless attack threat detection from the beginning, it serves as an initial step towards comprehensive event logging and analysis, capturing all events that exhibit any form of new or changing behavior we observe. Therefore, initially, the greatest value lies in combining it with regular Falco rules based on the anomaly-filtered event stream.
## Why now?
In case you haven't noticed, advanced data analytics is quite the big deal these days, and we can leverage robust established algorithms used in real production settings across various industries. The novelty lies in addressing the specific data encoding challenges unique to the field of cybersecurity, not re-inventing already established algorithms.
Furthermore, over the past several Falco releases, we have significantly improved stability, configurability, and capabilities. Notably, the plugins system has been refined over the past year to efficiently access the complete `libsinsp` state, now also featuring an improved CPP SDK. Additionally, it now seamlessly collaborates with the existing primary syscalls event source, deviating from its original purpose of processing new data sources. This improvement allows for more intuitive functionality, as demonstrated by the new `k8smeta` plugin. Now is the opportune time to further enhance proven threat detection capabilities and expand the plugins system even more.
*Initial community feedback concerning the KubeCon NA 2023 Full Talk*
- Overall, the feedback for [A Wind of Change for Threat Detection](https://kccncna2023.sched.com/event/1R2mX/a-wind-of-change-for-threat-detection-melissa-kilby-apple) was very positive and appreciative, particularly regarding the direct real-life benefits (a safety boundary for Falco rules enabling broader monitoring that won't blow up in production). Suggestions for future development included integrating the sketch directly into the kernel driver (which would be a remarkable achievement if feasible). Lastly, people have inquired about the timeline for the availability of this feature.
- Refer to the [KubeCon NA 2023 Slides](https://static.sched.com/hosted_files/kccncna2023/c5/A%20Wind%20of%20Change%20for%20Threat%20Detection%20-%20Melissa%20Kilby%20-%20KubeCon%20NA%202023.pdf) or [attached PDF](kubeconna23-anomaly-detection-slides.pdf) for more information. Here's the [Talk Recording](https://www.youtube.com/watch?v=1y1m9Vz93Yo) (please note that the first four minutes of the video are missing, but the slides and audio recordings are complete).
*Falco Community Call - January 17, 2024*
See dedicated [HackMD](https://hackmd.io/Ss0_1avySUuxArBQm-oaGQ?view):
- While not blocking the start of the plugin or an alpha dev version, there's feedback from @jasondellaluce that plugins cannot access the existing `libsinsp` filtercheck. It would be advantageous to enable this access to avoid reimplementing them and the constant risk of falling out of sync with `libs`. @leogr mentioned that supporting this over time should be possible.
- We have discussed the plugins config and are currently undecided on whether the definition of the behavior profile per sketch, meaning the fields that are string concatenated together and counted, should reside in the plugins config or in the rules files. The latter would potentially require a new rules component. Final decisions will be deferred to a later stage to ensure the config is intuitive, and we want to guarantee proper sketch definition when attempting to run Falco rules using the `anomalydetection` plugin.
- One use case, namely determining if a rule has previously occurred in a container, could be addressed by this framework as well. However, we are currently unsure how to expose the rule names, as `libsinsp` is not aware of them. This may be an optimization we can address later and does not block the development of an initial version.
- Future use cases might involve counting distinct values, utilizing the hyper log log algorithm. However, there will be additional technical challenges to overcome.
- Finally, just to reiterate some feedback from the KubeCon talk, there's a suggestion that, perhaps in the future, we could pass intelligence back and forth between the drivers and userspace. This idea has been discussed independently, especially in the context of kernel-side filtering. However, such capabilities would be a long-term consideration.

# Features Adoption and Deprecation Policies Proposal
This proposal aims to introduce a balance between maintaining adopter trust and the need for The Falco Project to evolve. Historically, Falco has favored rapid evolution over providing long-term support for features and interfaces. However, some project subsystems have been implicitly assumed not to allow backward-incompatible changes (e.g., we have almost never removed a condition syntax field). These implicit conventions have never been formalized, and decisions in this regard have been left unspecified.
## Goals
- Establish adopter expectations on the operational cost of using Falco.
- Provide a clear path for features to be adopted and dismissed.
- Allow quick evolution and experimentation without disrupting our adopters' deployments.
- Detail the process for introducing new features, following a "sandbox" to "incubating" to "stable" progression.
- Define the scope of the policy, including which aspects of Falco are covered (e.g., command line flags, configuration files, rules syntax).
- Establish stages for deprecating features, aligning with the project's current status (pre- and post-1.0 stages).
- Adopt a semantic versioning (semver) approach.
## Non-Goals
- Define the number of previous releases that will receive patches or security updates and the duration of this support.
- Define the criteria for Falco 1.0.
## Scope
The proposed policies apply to Falco, its subsystems (e.g., rules, the plugin system), and all [core projects](https://github.com/falcosecurity/evolution#core) which are deemed [stable](https://github.com/falcosecurity/evolution/blob/main/REPOSITORIES.md#stable), thus officially supported by The Falco Project.
## Definitions
### Feature Changes
A feature is a distinct and specific functionality or characteristic of Falco and its core components that provides value to the user by enabling them to perform particular tasks. Features encompass aspects such as functionality, user value, usability, integrability, scalability, configurability, and discoverability. Features can range from essential user interface elements to complex, multifunctional operations.
A feature change refers to any modification or update to an existing feature or the addition of a new feature. This does not include documentation, Falco compatibility across different environments, platforms, systems, or other software or hardware, bug fixing (stated it does not require a feature change to overcome the problem), and performance (unless a change produces a measurable effect on usability).
### Behavior Changes
A behavior change refers to alterations in how Falco, or a specific feature within it, operates or responds under certain conditions. Unlike feature changes, behavior changes are more about tweaking the underlying logic or the way existing features interact or perform, particularly the expected behavior of Falco when run with the default configuration.
Behaviors are generally documented. Any modification that does not meet the conditions and expectations of an already documented feature is assumed to be a behavior change.
Undocumented behaviors may be included in this definition if there's strong evidence or suspicion that users rely on those undocumented behaviors.
### User-Facing Changes
User-facing changes refer to any feature changes, behavior changes, modifications, or additions that are directly noticeable and interactable by the end users. These changes affect how Falco operates from the user's perspective (notably any change that can lead to user disruption). Unlike internal changes (i.e., code refactoring, CI, maintenance-related changes), which are under-the-hood improvements not directly visible to the user, user-facing changes are evident in the Falco and its core components interface and functionality.
### CLI/Config Area
Falco is comprised of the Falco binary and other programs and tools cooperating (notably [falcoctl](https://github.com/falcosecurity/falcoctl)). These programs are the primary user interface for Falco. Any feature or behavior changes to the following elements of these programs are assumed to be user-facing changes to the CLI/Config area:
- Program name.
- Distribution mechanism and packaging (e.g., a container image).
- Command line flags and options.
- Environment variables.
- Configurations.
- Elements that affect the program's lifecycle (e.g., the effect of sending a SIGINT to the program).
- Elements that allow scripting, automation, or interaction with other programs (e.g., piping and redirection).
- Program inputs, excluding elements explicitly governed by other areas (e.g., [Falco rules](#rules-area)).
- Program outputs excluding elements explicitly governed by other areas (e.g., [Falco outputs/alerts](#outputs-alerts-area)).
### Rules System Area
Rules are the primary input for Falco. Any feature or behavior changes to the following aspects or elements are assumed to be user-facing changes to the rules system area:
- Syntax.
- File format.
- Schema (i.e., supported fields).
- Elements that affect the way users can implement rules.
- Elements that affect the way rules are triggered.
However, any change related to the rule's output when triggered (i.e., the alert) is out of scope for this area (see next section).
Note that this area does not include changes related to the ruleset files. Ruleset distributions follow their own [Rules Maturity Framework](https://github.com/falcosecurity/rules/blob/main/CONTRIBUTING.md#rules-maturity-framework) policies.
### Outputs/Alerts Area
Alerts, delivered through Falco output channels, are Falco's primary output. The way and the format in which alerts are produced can have a significant impact on adopters. For example, removing a supported rule field also impacts this area, as adopters may have relied on that field when consuming Falco output.
Any feature or behavior changes to the following aspects or elements are assumed to be user-facing changes to the Outputs/Alerts area:
- Output and logging formats.
- Schema of outputted data (i.e., supported fields).
- Falco output channels.
- Any element that might be consumed from the output.
### Subsystem APIs (Plugins, gRPC Output, Metrics, etc.) Area
Falco is also comprised of several subsystems providing specific APIs. These subsystems notably include plugin system API, gRPC output API, and metrics API.
In the context of this proposal, only changes to **public APIs** are assumed to be user-facing changes to this area.
Public APIs are defined as those supporting Falco functioning and explicitly intended for user usage. Internal APIs consumed by Falco or other tools are out of scope for this area. For instance, the driver APIs or libs APIs are intended to be mainly consumed by Falco and not by users.
### Platform Support Area
Platform support for Falco encompasses the range of platforms, systems, and environments it is designed to operate in. Platform support may significantly vary by Falco's data sources and use cases. For example, its compatibility differs when utilized for Kubernetes audit events versus system call events. Additionally, platform support can be influenced by deployment methods (e.g., directly on a host versus within Kubernetes) or configurations (e.g., running in privileged versus least privileged mode).
Given the diversity of potential platforms and setups, only those explicitly listed in Falco's documentation are considered officially supported. While Falco may function on other platforms, official support is guaranteed solely for documented ones.
Therefore, changes in platform compatibility or behavior that are documented explicitly assumed to be user-facing changes to the Platform Support area.
### Release Cycle
In the context of this proposal, a release cycle is the period between two consecutive major or minor releases of Falco. Hotfix/Patch releases must not be counted.
The actual duration of a release cycle can vary. Still, it's assumed to be about 16 weeks (as per our current defined [Release Cycles and Development Iterations](https://github.com/falcosecurity/falco/blob/master/proposals/20230511-roadmap-management.md#release-cycles-and-development-iterations)). In case of future modification to the Falco release schedule, a period of minimum 3 months must be assumed.
## Proposal
### Maturation Levels
Maturation levels (inspired by those we already have in place for [repositories](https://github.com/falcosecurity/evolution/blob/main/REPOSITORIES.md#status)) are used to characterize the maturity of a feature. Each feature will have an assigned level at any specific time (i.e., a Falco release). Levels are shown in the table below.
| Maturity Level | Intended for |
| --- | --- |
| Sandbox | Experimental/alpha features, not recommended for production use, can be removed at any time without further notice. |
| Incubating | Beta features, long-term support is not guaranteed. |
| Stable | General Availability (GA) features for which long-term support is expected. |
| Deprecated | See the [deprecation policy](#Deprecation-policy) section below. |
### Adoption Policy
The adoption policy applies to any backward compatible user-facing changes which add functionalities. For non-backward compatible changes see the [deprecation policy](#Deprecation-policy) below.
**Adoption rules**:
1. A feature can be introduced at only one of the following levels:
- Sandbox: The feature must be opt-in (e.g., not enabled by default), labeled as *Sandbox* and the user must be proactively informed by the experimental nature of the feature (i.e. emitting a notice when the feature is being enabled).
- Incubating: The feature must be labeled as *Incubating*.
2. Any functionality additions to an existing feature are inherently introduced at the same level as the feature itself unless logically separable (for instance, a sub-feature that may be enabled separately).
3. A feature can be promoted *from Sandbox to Incubating* or *from Incubating to Stable* only after at least one release cycle has passed without user-facing changes to the feature.
4. A feature cannot be demoted to a previous level.
_Note about behaviors_:
This policy indirectly applies to behaviors, too. Behavior changes are assumed to be a consequence of a feature change. The adoption level of a documented behavior is considered to be the same as the related feature. Furthermore, behavior changes are particularly relevant in the context of deprecation (see the next section).
### Deprecation Policy
The deprecation policy applies to any non-backward compatible user-facing changes. Any other changes introduced in a backward-compatible manner does not fall under the scope of this deprecation policy.
**Deprecation rules**:
1. Sandbox features can be removed or changed at any time without notice. No deprecation period is required.
2. Incubating or Stable features and documented behaviors must enter a deprecation period and function for no less than the indicated release cycles (see tables below) after their announced deprecation.
- If the change affects the feature partially, the deprecation applies only to that feature part.
- If the change removes the feature entirely, the deprecation applies to the entire feature.
3. At least for the entire deprecation period, the feature must be labeled as *Deprecated* in all relevant documentation, and:
- for deprecated configurations or CLI elements, a warning must be emitted warnings when the feature is being enabled or used;
- for deprecated APIs, when technically feasible, the API should be signal the deprecation status (this may vary depending on the specific subsystem);
- for deprecated behaviors the documentation must highlight the _before_ and _after_ behavior, alongside with a prominent deprecation notice.
4. Any Pull Request introducing a deprecation notice must be labeled and include a note in the format `DEPRECATION NOTICE: ...`.
5. Any Pull Request introducing a breaking change due to the end of the deprecation notice period must be labeled and include a note in the format `BREAKING CHANGE: ...`.
- It is also recommended for code commits that introduce a breaking change to follow the related [conventional commit spec](https://www.conventionalcommits.org/en/v1.0.0/#specification).
The minimum deprecation period length depends on the affected area. If a single change spans multiple areas, the area with the most extended deprecation period is assumed. Longer deprecation periods are allowed if the feature is deemed to be particularly critical or widely used.
#### Deprecation Period Lengths
_The units represent the number of releases._
##### Before Falco 1.0
| Area | Stable | Incubating |
| -------------- | ------ | ---------- |
| *all areas* | 1 | 0 |
##### Since Falco 1.0 onward
| Area | Stable | Incubating |
| -------------- | ------ | ---------- |
| Behaviors | 2 | 1 |
| Rules System | 2 | 1 |
| Output/Alerts | 2 | 1 |
| Platform | 2 | 1 |
| CLI/Config | 1 | 1 |
| Subsystem APIs | 1 | 0 |
### Examples
**Example 1** Let's consider a feature _foo_ in the Output/Alerts Area introduced in Falco 1.0.0 and labeled as *Incubating*. The feature is promoted to *Stable* in Falco 1.1.0 (because the feature did not get any user-facing change).
Subsequently, maintainers decide that backward-incompatible changes must be introduced in _foo_ to improve its functionality. The part of the feature to be changed is labeled as *Deprecated* in Falco 1.2.0, and the deprecation period starts. The non-backward compatible change is then introduced in Falco 1.4.0.
**Example 2** The `--bar` flag in the CLI/Config Area has been introduced since Falco 1.1.0 and is labeled as *Stable*. Before releasing Falco 1.5.0, maintainers realize `--bar` is redundant and should be removed. The flag is labeled as *Deprecated* in Falco 1.5.0, and the deprecation period starts. The flag is removed in Falco 1.6.0.
### Exceptions
- Ruleset in the official distributions follow the [Rules Maturity Framework](https://github.com/falcosecurity/rules/blob/main/CONTRIBUTING.md#rules-maturity-framework) policies.
- Subsystems or subcomponents may have additional criteria and exceptions. Stated other criteria and exceptions must not directly affect the main Falco distribution (e.g., *falcoctl* can have a different release cycle and different policies; however, if Falco relies on a specific *falcoctl* feature, that *falcoctl* feature adoption and deprecation must be strictly compatible with the rules described in this proposal).
- Internal APIs are out of scope for this policy. Their adoption models and deprecation policies might be regulated separately.
- Different parties may provide plugins, and each plugin may have a different maturity level. Only those plugins officially maintained by The Falco Project and identified as "core" for Falco are in scope for this policy; all others are excluded.
- Any other exceptions to the rules provided by this policy require a formal core maintainer majority vote.
### Versioning
Regarding the above policies, component versioning must adhere to [Semantic Versioning 2.0.0](https://semver.org/). However, in the context of Falco core components, the scope extends beyond the strict API definition and includes any user-facing changes.
Thus, given a version number `MAJOR.MINOR.PATCH` increment the:
- *MAJOR* version when the deprecation period of one or more _stable_ features ends, thus introducing incompatible user-facing or API changes.
- *MINOR* version when adding functionality in a backward-compatible manner.
- *PATCH* version when making backward-compatible bug fixes.
Moreover, *MAJOR* version zero (0.y.z) is for versioning stabilization (i.e., before defining the public set of user-facing features and APIs). At this stage, the *MINOR* version is allowed to be incremented instead of the *MAJOR* version.
### Documentation
Documentation must be tied to a specific release and reflect the adoption level status of a feature at that specific release. In particular:
- Deprecated items must be labeled `DEPRECATED` in all relevant documentation.
- Stable items must be sufficiently documented. Explicitly labeling the Stable status is not required or recommended.
- Incubating items must be sufficiently documented and labeled `INCUBATING` in all relevant documentation.
- Sandbox items may be partially documented and labeled `SANDBOX` in all relevant documentation, if any. The relevant documentation must also explicitly state the experimental nature of the item.
## Transition Phases
Since software components may need to adapt to implement the requirements this proposal mandates, we assume the following stages are required to transition from the current state to the desired state fully:
- Within Falco 0.38, at least stable features must be identified, and the adoption policy and relevant documentation should be implemented in Falco. Exceptions may be made temporarily for the deprecation policy.
- Within subsequent releases and no later than Falco 1.0.0 (still not scheduled to date), all the policies must be strictly implemented in Falco and documented in [falco.org](falco.org). The [Rules Maturity Framework](https://github.com/falcosecurity/rules/blob/main/CONTRIBUTING.md#rules-maturity-framework) must be adapted to ensure it aligns with the spirit of this proposal. Exceptions may be made temporarily for other [core projects](https://github.com/falcosecurity/evolution#core) with [stable](https://github.com/falcosecurity/evolution/blob/main/REPOSITORIES.md#stable) status, assuming exceptions don't severely affect the main Falco distribution.
- Within Falco 1.1.0, all the policies must be strictly implemented in Falco and in all [core projects](https://github.com/falcosecurity/evolution#core) with [stable](https://github.com/falcosecurity/evolution/blob/main/REPOSITORIES.md#stable) status.
During the transition phases, maintainers can fine-tune these policies and add further exceptions, eventually. After this initial transition phases, the policy is assumed to be established. From then on, any policy modifications, updates, and exceptions must be subject to a core maintainer majority vote to ensure the policy remains relevant and practical.

message: >-
The program calls a function that can never be guaranteed to work
safely.
Certain functions behave in dangerous ways regardless of how they are
used. Functions in this category were often implemented without
taking security concerns into account. The gets() function is unsafe
because it does not perform bounds checking on the size of its input.
An attacker can easily send arbitrarily-sized input to gets() and
overflow the destination buffer.

confidence: HIGH
message: >-
The program invokes a potentially dangerous function that could
introduce a vulnerability if it is used incorrectly, but the function
can also be used safely.
A buffer overflow condition exists when a program attempts to put
more data in a buffer than it can hold, or when a program attempts to
put data in a memory area outside of the boundaries of a buffer. The
simplest type of error, and the most common cause of buffer
overflows, is the classic case in which the program copies the buffer
without restricting how much is copied. Other variants exist, but the
existence of a classic overflow strongly suggests that the programmer
is not considering even the most basic of security protections.
