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 374 is passing Here is how to embed it:

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

        

 Basics 0/5 ●

  • Identification

    Xen Project is a Linux Foundation Collaborative Project that develops the Xen Hypervisor and related virtualization technologies. The Xen Hypervisor is a leading virtualization platform that is powering some of the largest clouds in production today, such as Amazon Web Services, Rackspace Public Cloud, Alibaba Cloud (Aliyun) and many hosting services. It also fosters the creation of lightweight Unikernel systems with the Mirage OS incubator project, as well as many independent efforts which use our hypervisor as a base for their work.

  • Prerequisites


    Not enough for a badge.

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

  • Project oversight


    Unknown required information, not enough for a badge.

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

    Unknown required information, not enough for a badge.

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

  • Other


    Unknown required information, not enough for a badge.

    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]

  • Public version-controlled source repository


    Enough for a badge!

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

    Uses git.


    Unknown required information, not enough for a badge.

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

    Unknown required information, not enough for a badge.

    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]

    Unknown required information, not enough for a badge.

    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]

  • Coding standards


    Unknown required information, not enough for a badge.

    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]

    Unknown required information, not enough for a badge.

    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]

  • Working build system


    Not enough for a badge.

    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]

    This would be a good idea. We don't have it right now, but we have accepted patches towards this goal (patches were submitted by the Debian reproducible builds folks).


  • Automated test suite


    Enough for a badge!

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

    See the README files in the relevant repositories, as well as https://xenbits.xen.org/docs/xtf/


    Unknown required information, not enough for a badge.

    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]

    OSSTEST and the projects Test Farm implements continuous integration. In addition we do random build testing for different compilers (various gcc and clang versions) via Travis

    Warning: URL required, but no URL found.


    Unknown required information, not enough for a badge.

    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]

    Unknown required information, not enough for a badge.

    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.

    Enough for a badge!

    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 do not use HTTP as an RPC transport. The toolstack software uses cryptography for migration, but it just uses whatever ssh you have as a transport (by default). We do support VNC, which has some encryption features. The encryption is entirely done by qemu using TLS.


    Enough for a badge!

    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]

    After checking with the Linux Foundation, we were advised that we do not need to verify such choices for upstreams we depend on. In our case, we use QEMU which uses TLS for VNC.


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


    Not enough for a badge.

    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]

    X-Content-Type-Options was not set to "nosniff".


  • Other security issues


    Unknown required information, not enough for a badge.

    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]

    Unknown required information, not enough for a badge.

    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]

    This is rather vague and needs more information to identify what is acceptable and what is not.


  • Dynamic code analysis


    Enough for a badge!

    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]

    The project runs American Fuzzy Lop over some portions of the codebase as part of its test infrastructure. This capability is being extended to cover more components. In addition tests which verify whether discovered, disclosed and fixed vulnerabilities are present in releases and master are run as part of the project's test infrastructure.

    In addition, 3rd party test infrastructure which has extensive fuzzing capability (such as Citrix' XenRT) are run on RCs (but also at regular intervals between releases) as part of the projects release process and issues are reported to the Xen Security team.


    Enough for a badge!

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

    The Xen Project code base has a large number of run-time assertions in DEBUG builds. The test infrastructure tests against both RELEASE and DEBUG builds.
