Default Branch Should Require All Commits To Be Signed

policy name: no_signed_commits

severity: LOW

Description

Require all commits to be signed and verified

Threat Example(s)

A commit containing malicious code may be crafted by a malicious actor that has acquired write access to the repository to initiate a supply chain attack. Commit signing provides another layer of defense that can prevent this type of compromise.

Remediation

  1. Make sure you have owner permissions
  2. Go to the projects’s settings -> Repository page
  3. Enter “Push Rules” tab. Set the “Reject unsigned commits” checkbox
