How to prevent some files to be modified in github?

Question

Let's say I have a GitHub repository that has a config file for a CI/CD tool, e.g. Jenkins. In my CI/CD pipeline, I have a unit test step, in which all unit tests inside tests directory of the repository are run. Now in this case, someone malicious, who has access to the repository may add a malicious script inside the tests directory. Is there a way to tell GitHub to ignore pushes that have changes to the tests directory???

Answer 1

You don't let malicious people have write access to your repository. Git isn't the right solution here.
