These practices provide a structured framework that ensures projects are secure, maintainable, and scalable. By fostering a collaborative and efficient environment, these guidelines help organizations avoid common pitfalls, maintain high-quality codebases, and streamline project workflows. Ultimately, adhering to these best practices leads to successful and sustainable software projects.
Key design strategies and checklist
Use these key strategies as a baseline to implement GitHub’s best practices for governance:
Restrict Actions execution to specific repositories and not let repo users and owners to arbitrarily create and execute actions workflow. Set this at the Organization level.
Use Actions created by GitHub and Verified Creators wherever applicable. This settings can be enforced at Enterprise level.
Default Workflow token permission should be read-only: Following the principle of least privilege, it is recommended to set the default workflow token permissions to read-only. Default is read/write, which should be avoided because if a token is compromised, malicious actors can run exploits within the GitHub platform through actions execution.
Disable auto approval of Pull Requests. By default it is enabled, but it might lead to attackers bypassing code reviews for pull requests and thus approving and merging pull requests unintentionally. This can be set at either the Enterprise or Organizational level.
Disable forking if not absolutely needed: You can help prevent sensitive information from being exposed by disabling the ability to fork repositories in your organization.
Disable changing repository visibility: You should restrict who has the ability to change the visibility of repositories in your organization, such as changing a repository from private to public. Restricting who has the ability to change the visibility of repositories in your organization helps prevent sensitive information from being exposed.
Implement approval flow for fine grained personal access tokens. If enabled at the Enterprise or Organization level, all organization members must request to get approval for their fine-grained personal access tokens that access any organization in your enterprise. This will help in reviewing which users are accessing what resources and with permissions on the PAT.
Enterprise owners should create a policy to prevent org members from inviting outside collaborators. Default is “No Policy”. Recommended is Enterprise owners or Organization Owners, so that there is centralized control on who can invite and vet outside collaborators.
Set up an Enterprise policy which which prevents users and members from creating public repositories.
Webhooks should always be configured with a secret. Not using a secret in the webhook will mislead the receiving entity of the webhook on the authenticity of the payload received.
Webhooks should be configured to use SSL.
Always use Repository Rulesets with fine grained policy enforcements around checks needing pull request review, required checks, and leverage protected branches.
Define CODEOWNERS: To protect a repository against unauthorized changes, you also need to define owners using a
CODEOWNERSfile. The most secure method is to define aCODEOWNERSfile in the.githubdirectory of the repository and define the repository owner as the owner of either theCODEOWNERSfile (/.github/CODEOWNERS @owner_username) or the whole directory (/.github/ @owner_username).Initiate and impose commit signing whenever possible. This will deter malicious actors from creating a commit with malicious code and help prevent a possible supply chain attack.
Bypass of rulesets should not be allowed under the Repository Ruleset configuration. Enforcing policies around repo ruleset is designed for a reason and allowing users to bypass rulesets might allow an attacker to gain access as a user who is allowed to bypass ruleset and compromise the integrity of the codebase.
Runner groups should be limited to a select number of repositories. Configuring a runner group for all repositories can expose vulnerabilities or allow malicious actors to exploit misconfigured runners. Additionally, maintaining runner groups for specific repositories ensures that self-hosted runners are used for their intended specialized workloads. Granting access to everyone in the organization can lead to wasting resources on unnecessary execution tasks.
Bypass Push Protection: By default, anyone with write access can bypass a commit blockage due to protection. Considering the criticality of leaked secrets, it is recommended to have bypass capability limited to spefic roles and teams.
Audit log streaming is often overlooked by enterprises when implementing GitHub. Streaming audit logs from GitHub is crucial for monitoring platform usage trends. The extensive data captured in these logs provides valuable insights into potential unwanted activities occurring on the platform.
