Lightning Talk: Automatically Restrict Permissions for the GITHUB Token - Varun Sharma, StepSecurity

There are millions of open-source projects on GitHub. GitHub Actions is a CI/CD platform and there are over 2 million GitHub Actions workflows used by open-source projects.  

Each GitHub Actions workflow gets a GITHUB token. Restricting permissions for this token is recommended by the GitHub Actions Hardening Guide and by Open Source Security Foundation (OSSF) Security Scorecards.  

Setting permissions for this token is hard. There is a steep learning curve. Different GitHub Actions need different permissions, so developers must painfully research the correct permissions for each Action used in their workflow. Many developers are not aware of this token or that permissions can actually be restricted.  

SecureWorkflows (https://github.com/step-security/secure-workflows) is an open-source project that enables automatic restriction of permissions for the GITHUB token. It has been used to set token permissions for hundreds of workflows, including for the GitHub Actions starter workflows, and is recommended by OSSF Scorecards to fix token permissions. 

This talk will discuss the importance of setting minimum permissions for the GITHUB token, share a real use case where the token was used to overwrite a release branch in Visual Studio Code’s GitHub repository, and give an overview & demo of the SecureWorkflows project.
