OwaspHeaders.Core

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 9723 is in_progress Here is how to embed it:

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

        

 Basics 11/17

  • Identification

    Inject OWASP recommended HTTP Headers for increased security in a single line

  • Prerequisites


    The project MUST achieve a passing level badge. [achieve_passing]

  • Basic project website content


    The information on how to contribute MUST include the requirements for acceptable contributions (e.g., a reference to any required coding standard). (URL required) [contribution_requirements]

    The documentation site for the project has an entire page on contributing to the project -> https://gaprogman.github.io/OwaspHeaders.Core/Contributing/; including a code of conduct and a PR template (which is enforced when creating a PR)


  • Project oversight


    The project SHOULD have a legal mechanism where all developers of non-trivial amounts of project software assert that they are legally authorized to make these contributions. The most common and easily-implemented approach for doing this is by using a Developer Certificate of Origin (DCO), where users add "signed-off-by" in their commits and the project links to the DCO website. However, this MAY be implemented as a Contributor License Agreement (CLA), or other legal mechanism. (URL required) [dco]


    The project MUST clearly define and document its project governance model (the way it makes decisions, including key roles). (URL required) [governance]


    The project MUST adopt a code of conduct and post it in a standard location. (URL required) [code_of_conduct]

    The project MUST clearly define and publicly document the key roles in the project and their responsibilities, including any tasks those roles must perform. It MUST be clear who has which role(s), though this might not be documented in the same way. (URL required) [roles_responsibilities]


    The project MUST be able to continue with minimal interruption if any one person dies, is incapacitated, or is otherwise unable or unwilling to continue support of the project. In particular, the project MUST be able to create and close issues, accept proposed changes, and release versions of software, within a week of confirmation of the loss of support from any one individual. This MAY be done by ensuring someone else has any necessary keys, passwords, and legal rights to continue the project. Individuals who run a FLOSS project MAY do this by providing keys in a lockbox and a will providing any needed legal rights (e.g., for DNS names). (URL required) [access_continuity]


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

    The project has 10 contributes, with three recent contributors. https://github.com/GaProgMan/OwaspHeaders.Core/graphs/contributors


  • Documentation


    The project MUST have a documented roadmap that describes what the project intends to do and not do for at least the next year. (URL required) [documentation_roadmap]


    The project MUST include documentation of the architecture (aka high-level design) of the software produced by the project. If the project does not produce software, select "not applicable" (N/A). (URL required) [documentation_architecture]

    See the project documentation: https://gaprogman.github.io/OwaspHeaders.Core/



    The project MUST document what the user can and cannot expect in terms of security from the software produced by the project (its "security requirements"). (URL required) [documentation_security]

    This is covered in the security file in the GitHub repository: https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/SECURITY.md



    The project MUST provide a "quick start" guide for new users to help them quickly do something with the software. (URL required) [documentation_quick_start]

    The project MUST make an effort to keep the documentation consistent with the current version of the project results (including software produced by the project). Any known documentation defects making it inconsistent MUST be fixed. If the documentation is generally current, but erroneously includes some older information that is no longer true, just treat that as a defect, then track and fix as usual. [documentation_current]

    The project repository front page and/or website MUST identify and hyperlink to any achievements, including this best practices badge, within 48 hours of public recognition that the achievement has been attained. (URL required) [documentation_achievements]
  • Accessibility and internationalization


    The project (both project sites and project results) SHOULD follow accessibility best practices so that persons with disabilities can still participate in the project and use the project results where it is reasonable to do so. [accessibility_best_practices]

    The documentation site (https://gaprogman.github.io/OwaspHeaders.Core/) currently scores a 96 on Google Chrome's accessibility testing



    The software produced by the project SHOULD be internationalized to enable easy localization for the target audience's culture, region, or language. If internationalization (i18n) does not apply (e.g., the software doesn't generate text intended for end-users and doesn't sort human-readable text), select "not applicable" (N/A). [internationalization]

    The software doesn't generate text intended for end-users and doesn't sort human-readable text


  • Other


    If the project sites (website, repository, and download URLs) store passwords for authentication of external users, the passwords MUST be stored as iterated hashes with a per-user salt by using a key stretching (iterated) algorithm (e.g., Argon2id, Bcrypt, Scrypt, or PBKDF2). If the project sites do not store passwords for this purpose, select "not applicable" (N/A). [sites_password_security]

    This project and it's sites do not explicitly store any user data in any form


  • Previous versions


    The project MUST maintain the most often used older versions of the product or provide an upgrade path to newer versions. If the upgrade path is difficult, the project MUST document how to perform the upgrade (e.g., the interfaces that have changed and detailed suggested steps to help upgrade). [maintenance_or_update]

    Every version of the software built from the main branch is archived at NuGet: https://www.nuget.org/packages/OwaspHeaders.Core/ There are also manually created releases on the GitHub repository for the project: https://github.com/GaProgMan/OwaspHeaders.Core/releases


  • Bug-reporting process


    The project MUST use an issue tracker for tracking individual issues. [report_tracker]

    This project makes use of the GitHub issues feature for submitting bugs: https://github.com/GaProgMan/OwaspHeaders.Core/issues


  • Vulnerability report process


    The project MUST give credit to the reporter(s) of all vulnerability reports resolved in the last 12 months, except for the reporter(s) who request anonymity. If there have been no vulnerabilities resolved in the last 12 months, select "not applicable" (N/A). (URL required) [vulnerability_report_credit]

    There have been no vulnerabilities resolved in the last 12 months at this time.



    The project MUST have a documented process for responding to vulnerability reports. (URL required) [vulnerability_response_process]

  • Coding standards


    The project MUST identify the specific coding style guides for the primary languages it uses, and require that contributions generally comply with it. (URL required) [coding_standards]

    This project makes use of an .editorconfig file, and all PRs must pass an automated dotnet-format check which ensures that the code base matches those standards. See: https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/.github/workflows/dotnet.yml#L33



    The project MUST automatically enforce its selected coding style(s) if there is at least one FLOSS tool that can do so in the selected language(s). [coding_standards_enforced]

    This project makes use of an .editorconfig file, and all PRs must pass an automated dotnet-format check which ensures that the code base matches those standards. See: https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/.github/workflows/dotnet.yml#L33


  • Working build system


    Build systems for native binaries MUST honor the relevant compiler and linker (environment) variables passed in to them (e.g., CC, CFLAGS, CXX, CXXFLAGS, and LDFLAGS) and pass them to compiler and linker invocations. A build system MAY extend them with additional flags; it MUST NOT simply replace provided values with its own. If no native binaries are being generated, select "not applicable" (N/A). [build_standard_variables]

    Not applicable as native binaries are not provided.



    The build and installation system SHOULD preserve debugging information if they are requested in the relevant flags (e.g., "install -s" is not used). If there is no build or installation system (e.g., typical JavaScript libraries), select "not applicable" (N/A). [build_preserve_debug]

    This is met by NuGet build tooling, which reads the "IncludeSymbols" key in the main CSPROJ file (see: https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/src/OwaspHeaders.Core.csproj#L23) and uploads an SNUPKG file to NuGet, allowing consumers access to debug symbols when they install the package.



    The build system for the software produced by the project MUST NOT recursively build subdirectories if there are cross-dependencies in the subdirectories. If there is no build or installation system (e.g., typical JavaScript libraries), select "not applicable" (N/A). [build_non_recursive]

    The GitHub action which builds the project for packaging explicitly builds and packages all code found in a the root directory, only making use of one level of sub-directories: https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/.github/workflows/release.yml#L78



    The project MUST be able to repeat the process of generating information from source files and get exactly the same bit-for-bit result. If no building occurs (e.g., scripting languages where the source code is used directly instead of being compiled), select "not applicable" (N/A). [build_repeatable]

    The .NET SDK toolchain, along with the "Deterministic Build" flag (see: https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/src/OwaspHeaders.Core.csproj#L28) take care of this.


  • Installation system


    The project MUST provide a way to easily install and uninstall the software produced by the project using a commonly-used convention. [installation_common]

    This software is installed using the standard .NET tooling (i.e. "dotnet add package OwaspHeaders.Core") or the NuGet tooling provided inside of .NET IDEs.



    The installation system for end-users MUST honor standard conventions for selecting the location where built artifacts are written to at installation time. For example, if it installs files on a POSIX system it MUST honor the DESTDIR environment variable. If there is no installation system or no standard convention, select "not applicable" (N/A). [installation_standard_variables]

    This is handled by the .NET tooling, specifically the tooling around NuGet



    The project MUST provide a way for potential developers to quickly install all the project results and support environment necessary to make changes, including the tests and test environment. This MUST be performed with a commonly-used convention. [installation_development_quick]

    The project has a single support environment requirement: The .NET SDK. The readme covers how to get set up with that.


  • Externally-maintained components


    The project MUST list external dependencies in a computer-processable way. (URL required) [external_dependencies]

    This project has only one external dependency: The .NET SDK and runtime (which is bundled with the SDK)



    Projects MUST monitor or periodically check their external dependencies (including convenience copies) to detect known vulnerabilities, and fix exploitable vulnerabilities or verify them as unexploitable. [dependency_monitoring]

    As the project takes only one dependency (the .NET SDK), this is automatically met whenever a new version of the SDK is released.



    The project MUST either:
    1. make it easy to identify and update reused externally-maintained components; or
    2. use the standard components provided by the system or programming language.
    Then, if a vulnerability is found in a reused component, it will be easy to update that component. [updateable_reused_components]

    This project makes use of the standard components provided by both .NET and the C# programming language



    The project SHOULD avoid using deprecated or obsolete functions and APIs where FLOSS alternatives are available in the set of technology it uses (its "technology stack") and to a supermajority of the users the project supports (so that users have ready access to the alternative). [interfaces_current]

    All APIs in use are provided by .NET and C#. When one is deprecated, the next suitable API is chosen.


  • Automated test suite


    An automated test suite MUST be applied on each check-in to a shared repository for at least one branch. This test suite MUST produce a report on test success or failure. [automated_integration_testing]

    The automated test suite is run on the code base for every pull request (see: https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/.github/workflows/dotnet.yml#L85) and directly committing to the main branch is disabled.



    The project MUST add regression tests to an automated test suite for at least 50% of the bugs fixed within the last six months. [regression_tests_added50]

    There is a directory of tests specifically to protect against regressions: https://github.com/GaProgMan/OwaspHeaders.Core/tree/main/tests/OwaspHeaders.Core.Tests/RegressionTests



    The project MUST have FLOSS automated test suite(s) that provide at least 80% statement coverage if there is at least one FLOSS tool that can measure this criterion in the selected language. [test_statement_coverage80]

    The .NET tooling provides code and branch coverage, and each pull request includes a report on the code coverage for that pull request. See: https://github.com/GaProgMan/OwaspHeaders.Core/pull/146#issuecomment-2517781230 for an example


  • New functionality testing


    The project MUST have a formal written policy that as major new functionality is added, tests for the new functionality MUST be added to an automated test suite. [test_policy_mandated]

    This is explained in both the pull request template (https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/.github/pull_request_template.md) and the documentation around contributing (https://gaprogman.github.io/OwaspHeaders.Core/Contributing/)



    The project MUST include, in its documented instructions for change proposals, the policy that tests are to be added for major new functionality. [tests_documented_added]

    This is explained in both the pull request template (https://github.com/GaProgMan/OwaspHeaders.Core/blob/main/.github/pull_request_template.md) and the documentation around contributing (https://gaprogman.github.io/OwaspHeaders.Core/Contributing/)


  • Warning flags


    Projects MUST be maximally strict with warnings in the software produced by the project, where practical. [warnings_strict]

    The .NET tooling supports reporting compiler warnings as errors when the TreatWarningsAsErrors flag is enabled on all projects. This was added in PR 104: https://github.com/GaProgMan/OwaspHeaders.Core/pull/104. This is the maximum level provided by the .NET tooling for reporting warnings as errors


  • Secure development knowledge


    The project MUST implement secure design principles (from "know_secure_design"), where applicable. If the project is not producing software, select "not applicable" (N/A). [implement_secure_design]

    This software implements the OWASP Secure Headers Project (https://owasp.org/www-project-secure-headers/#div-headers)


  • 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 default security mechanisms within the software produced by the project MUST NOT depend on cryptographic algorithms or modes with known serious weaknesses (e.g., the SHA-1 cryptographic hash algorithm or the CBC mode in SSH). [crypto_weaknesses]

    The software makes no use of cryptographic functions in any way.



    The project SHOULD support multiple cryptographic algorithms, so users can quickly switch if one is broken. Common symmetric key algorithms include AES, Twofish, and Serpent. Common cryptographic hash algorithm alternatives include SHA-2 (including SHA-224, SHA-256, SHA-384 AND SHA-512) and SHA-3. [crypto_algorithm_agility]

    This software does not make use of any cryptographic algorithms



    The project MUST support storing authentication credentials (such as passwords and dynamic tokens) and private cryptographic keys in files that are separate from other information (such as configuration files, databases, and logs), and permit users to update and replace them without code recompilation. If the project never processes authentication credentials and private cryptographic keys, select "not applicable" (N/A). [crypto_credential_agility]

    This software does not make use of any authentication



    The software produced by the project SHOULD 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 SHOULD 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]

    This software does not send any external communications via any protocols



    The software produced by the project SHOULD, 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]

    The software does not use TLS



    The software produced by the project MUST, if it supports TLS, perform TLS certificate verification by default when using TLS, including on subresources. If the software does not use TLS, select "not applicable" (N/A). [crypto_certificate_verification]

    The software does not use TLS



    The software produced by the project MUST, if it supports TLS, perform certificate verification before sending HTTP headers with private information (such as secure cookies). If the software does not use TLS, select "not applicable" (N/A). [crypto_verification_private]

    The software does not use TLS


  • Secure release


    The project MUST cryptographically sign releases of the project results intended for widespread use, and there MUST be a documented process explaining to users how they can obtain the public signing keys and verify the signature(s). The private key for these signature(s) MUST NOT be on site(s) used to directly distribute the software to the public. If releases are not intended for widespread use, select "not applicable" (N/A). [signed_releases]


    It is SUGGESTED that in the version control system, each important version tag (a tag that is part of a major release, minor release, or fixes publicly noted vulnerabilities) be cryptographically signed and verifiable as described in signed_releases. [version_tags_signed]

  • Other security issues


    The project results MUST check all inputs from potentially untrusted sources to ensure they are valid (an *allowlist*), and reject invalid inputs, if there are any restrictions on the data at all. [input_validation]

    The software does not read user input



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

    This software implements the OWASP Secure Headers Project (https://owasp.org/www-project-secure-headers/#div-headers)



    The project MUST provide an assurance case that justifies why its security requirements are met. The assurance case MUST include: a description of the threat model, clear identification of trust boundaries, an argument that secure design principles have been applied, and an argument that common implementation security weaknesses have been countered. (URL required) [assurance_case]

  • Static code analysis


    The project MUST use at least one static analysis tool with rules or approaches to look for common vulnerabilities in the analyzed language or environment, if there is at least one FLOSS tool that can implement this criterion in the selected language. [static_analysis_common_vulnerabilities]

    The project makes use of CodeQL on all Pull Requests to main (directly committing to main is disabled). The CodeQL analysis is also run on a weekly basis.


  • Dynamic code analysis


    If the software produced by the project includes software written using a memory-unsafe language (e.g., C or C++), then at least one dynamic tool (e.g., a fuzzer or web application scanner) MUST be routinely used in combination with a mechanism to detect memory safety problems such as buffer overwrites. If the project does not produce software written in a memory-unsafe language, choose "not applicable" (N/A). [dynamic_analysis_unsafe]

    This is not applicable as the code reads values provided by ASP .NET Core rather than from user supplied files. We can make the assumption that ASP .NET Core has sufficient fuzzing involved in it's development process.
