To give people instructions for responsibly reporting security vulnerabilities in your project, you can add a SECURITY.md file to your repository's root,
.github folder. When someone creates an issue in your repository, they will see a link to your project's security policy.
You can create a default security policy for your organization or user account. For more information, see "Creating a default community health file."
Tip: To help people find your security policy, you can link to your SECURITY.md file from other places in your repository, such as your README file. For more information, see "About READMEs."
After someone reports a security vulnerability in your project, you can use GitHub Security Advisories to disclose, fix, and publish information about the vulnerability. For more information, see "About GitHub Security Advisories."
You can also join GitHub Security Lab to browse security-related topics and contribute to security tools and projects.
On GitHub, navigate to the main page of the repository.
Under your repository name, click Security.
In the left sidebar, click Policy.
Click Start setup.
In the new SECURITY.md file, add information about supported versions of your project and how to report a vulnerability.
At the bottom of the page, type a short, meaningful commit message that describes the change you made to the file. You can attribute the commit to more than one author in the commit message. For more information, see "Creating a commit with multiple co-authors."
Below the commit message fields, click the email address drop-down menu and choose a Git author email address. Only verified email addresses appear in this drop-down menu. If you enabled email address privacy, then
<username>@users.noreply.github.comis the default commit author email address. For more information, see "Setting your commit email address."
Below the commit message fields, decide whether to add your commit to the current branch or to a new branch. If your current branch is
master, you should choose to create a new branch for your commit and then create a pull request. For more information, see "Creating a new pull request."
Click Propose file change.
