Zephyr Project

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: Badge level for project 74 is gold Here is how to embed it:

These are the Gold level criteria. You can also view the Passing or Silver level criteria.

        

 Basics 5/5

  • Identification

    The Zephyr Project is a small, scalable real-time operating system for use on resource-constrained systems supporting multiple architectures. Developers are able to tailor their optimal solution. As a true open source project, the community can evolve the Zephyr Project to support new hardware, developer tools, sensor and device drivers. Advancements in security, device management capabilities, connectivity stacks and file systems can be easily implemented.

  • Prerequisites


    The project MUST achieve a silver level badge. [achieve_silver]

  • Project oversight


    The project MUST have a "bus factor" of 2 or more. (URL required) [bus_factor]

    Using the truck-factor tool, we have a TF of 12, see https://github.com/zephyrproject-rtos/zephyr/wiki/Truck-Factor for the output from the tool.



    The project MUST have at least two unassociated significant contributors. (URL required) [contributors_unassociated]
  • Other


    The project MUST include a license statement in each source file. This MAY be done by including the following inside a comment near the beginning of each file: SPDX-License-Identifier: [SPDX license expression for project]. [license_per_file]

    All files contain a SPDX license statement.


  • Public version-controlled source repository


    The project's source repository MUST use a common distributed version control software (e.g., git or mercurial). [repo_distributed]

    https://github.com/zephyrproject-rtos/ -- Repository on GitHub, which uses git. git is distributed.



    The project MUST clearly identify small tasks that can be performed by new or casual contributors. (URL required) [small_tasks]

    The project MUST require two-factor authentication (2FA) for developers for changing a central repository or accessing sensitive data (such as private vulnerability reports). This 2FA mechanism MAY use mechanisms without cryptographic mechanisms such as SMS, though that is not recommended. [require_2FA]

    Using Github 2FA and enforcing all contributors and members of the project to use this method of authentication.



    The project's two-factor authentication (2FA) SHOULD use cryptographic mechanisms to prevent impersonation. Short Message Service (SMS) based 2FA, by itself, does NOT meet this criterion, since it is not encrypted. [secure_2FA]

    Using Github 2FA and enforcing all contributors and members of the project to use this method of authentication.This method relies on google authenticator which is time based TOTP


  • Coding standards


    The project MUST document its code review requirements, including how code review is conducted, what must be checked, and what is required to be acceptable. (URL required) [code_review_standards]

    The project MUST have at least 50% of all proposed modifications reviewed before release by a person other than the author, to determine if it is a worthwhile modification and free of known issues which would argue against its inclusion [two_person_review]

    GH pull requests do not allow the original author to merge their own changes.


  • Working build system


    The project MUST have a reproducible build. If no building occurs (e.g., scripting languages where the source code is used directly instead of being compiled), select "not applicable" (N/A). (URL required) [build_reproducible]

    Reproducible builds are guaranteed with an SDK provided by the project that given a commit or the same state of the source code would generate the same binaries and output files. Timestamps are not enabled by default and used only for debugging and testing. https://github.com/zephyrproject-rtos/zephyr/wiki/Repeatable-Builds-by-Architecture


  • Automated test suite


    A test suite MUST be invocable in a standard way for that language. (URL required) [test_invocation]

    python script that is called to run test cases written in standard C. see https://github.com/zephyrproject-rtos/zephyr/blob/main/CONTRIBUTING.rst (twister)



    The project MUST implement continuous integration, where new or changed code is frequently integrated into a central code repository and automated tests are run on the result. (URL required) [test_continuous_integration]

    The project MUST have FLOSS automated test suite(s) that provide at least 90% statement coverage if there is at least one FLOSS tool that can measure this criterion in the selected language. [test_statement_coverage90]

    The project MUST have FLOSS automated test suite(s) that provide at least 80% branch coverage if there is at least one FLOSS tool that can measure this criterion in the selected language. [test_branch_coverage80]
  • Use basic good cryptographic practices

    Note that some software does not need to use cryptographic mechanisms. If your project produces software that (1) includes, activates, or enables encryption functionality, and (2) might be released from the United States (US) to outside the US or to a non-US-citizen, you may be legally required to take a few extra steps. Typically this just involves sending an email. For more information, see the encryption section of Understanding Open Source Technology & US Export Controls.

    The software produced by the project MUST support secure protocols for all of its network communications, such as SSHv2 or later, TLS1.2 or later (HTTPS), IPsec, SFTP, and SNMPv3. Insecure protocols such as FTP, HTTP, telnet, SSLv3 or earlier, and SSHv1 MUST be disabled by default, and only enabled if the user specifically configures it. If the software produced by the project does not support network communications, select "not applicable" (N/A). [crypto_used_network]

    We support TLS and DTLS for all communication protocols. HTTPS, COAPS and any other protocols can be abled with additional security enabled.



    The software produced by the project MUST, if it supports or uses TLS, support at least TLS version 1.2. Note that the predecessor of TLS was called SSL. If the software does not use TLS, select "not applicable" (N/A). [crypto_tls12]

    All configurations of the project use TLS 12 by default:

    lib/crypto/mbedtls/configs/config-ccm-psk-tls1_2.h:#define MBEDTLS_SSL_PROTO_TLS1_2 ext/lib/crypto/mbedtls/configs/config-coap.h:#define MBEDTLS_SSL_PROTO_TLS1_2 ext/lib/crypto/mbedtls/configs/config-mini-dtls1_2.h:#define MBEDTLS_SSL_PROTO_TLS1_2 ext/lib/crypto/mbedtls/configs/config-mini-tls1_2.h:#define MBEDTLS_SSL_PROTO_TLS1_2 ext/lib/crypto/mbedtls/configs/config-threadnet.h:#define MBEDTLS_SSL_PROTO_TLS1_2

    https://github.com/zephyrproject-rtos/zephyr/tree/master/ext/lib/crypto/mbedtls/configs


  • Secured delivery against man-in-the-middle (MITM) attacks


    The project website, repository (if accessible via the web), and download site (if separate) MUST include key hardening headers with nonpermissive values. (URL required) [hardened_site]

    The project websites implement hardening headers.

    www.zephyrproject.org https://github.com/zephyrproject-rtos/zephyr // One or more of the required security hardening headers is missing. // X-Content-Type-Options was not set to "nosniff".


  • Other security issues


    The project MUST have performed a security review within the last 5 years. This review MUST consider the security requirements and security boundary. [security_review]

    Hardening mechanisms MUST be used in the software produced by the project so that software defects are less likely to result in security vulnerabilities. (URL required) [hardening]

    We do build by default with -Wformat -Wformat-security -Wno-format-zero-length and stack-protector is enabled as an option where supported. It is disabled by default for performance reasons but can be enabled by the user. The master CMake file contents show this to be the case:

    https://github.com/zephyrproject-rtos/zephyr/blob/master/CMakeLists.txt


  • Dynamic code analysis


    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]

    GCOV and ASAN are used.



    The project SHOULD include many run-time assertions in the software it produces and check those assertions during dynamic analysis. [dynamic_analysis_enable_assertions]

    Assertions are enabled during test builds. There are "many" assertions in the code that are checked by this.
