policy name: requires_status_checks
Branch protection is enabled. However, the checks which validate the quality and security of the code are not required to pass before submitting new changes. The default check ensures code is up-to-date in order to prevent faulty merges and unexpected behaviors, as well as other custom checks that test security and quality. It is advised to turn this control on to ensure any existing or future check will be required to pass.
Not defining a set of required status checks can make it easy for contributors to introduce buggy or insecure code as manual review, whether mandated or optional, is the only line of defense.
