Projects that follow the best practices below can voluntarily self-certify and show that they've achieved an Open Source Security Foundation (OpenSSF) best practices badge.

If this is your project, please show your badge status on your project page! The badge status looks like this:

Here is how to embed it:

You can show your badge status by embedding this in your markdown file:

or by embedding this in your HTML:

The project MUST apply at least one dynamic analysis tool to any proposed major production release of the software produced by the project before its release. ^{[dynamic_analysis]}
A dynamic analysis tool examines the software by executing it with specific inputs. For example, the project MAY use a fuzzing tool (e.g., American Fuzzy Lop) or a web application scanner (e.g., OWASP ZAP or w3af). In some cases the OSS-Fuzz project may be willing to apply fuzz testing to your project. For purposes of this criterion the dynamic analysis tool needs to vary the inputs in some way to look for various kinds of problems or be an automated test suite with at least 80% branch coverage. The Wikipedia page on dynamic analysis and the OWASP page on fuzzing identify some dynamic analysis tools. The analysis tool(s) MAY be focused on looking for security vulnerabilities, but this is not required.

We do use AFL. The fuzzing could definitely be improved and expanded, but it's being conducted in an automated and continuous way (the fuzzer hardware is shared between several projects, each running a certain number of days per month). We also run unit-tests with a thread sanitizer.

Criterion [dynamic_analysis_enable_assertions]
Met

Unmet

N/A

?

The project SHOULD include many run-time assertions in the software it produces and check those assertions during dynamic analysis. ^{[dynamic_analysis_enable_assertions]}
This criterion does not suggest enabling assertions during production; that is entirely up to the project and its users to decide. This criterion's focus is instead to improve fault detection during dynamic analysis before deployment. Enabling assertions in production use is completely different from enabling assertions during dynamic analysis (such as testing). In some cases enabling assertions in production use is extremely unwise (especially in high-integrity components). There are many arguments against enabling assertions in production, e.g., libraries should not crash callers, their presence may cause rejection by app stores, and/or activating an assertion in production may expose private data such as private keys. Beware that in many Linux distributions NDEBUG is not defined, so C/C++ assert() will by default be enabled for production in those environments. It may be important to use a different assertion mechanism or defining NDEBUG for production in those environments.

Kea production code handles error situations with C++ exceptions. There's a configuration (--with-gtests or --with-gtest-source) available that validates the exceptions with massive amounts of asserts. A quick grep showed 17000+ asserts in our source code. Note we're using ASSERT_NO_THROW, ASSERT_THROW and similar macros from gtest suite.
