 ## GitOps Security
 
 To secure GitOps based deployments and reduce the risks of compromise, the GitOps deployment in the Shivering-Isles Infrastructure only accepts signed commits. This prevents a deployment of workload if an attackers mananges to push a commit onto the GitOps repository. The git forge itself is in charge of preventing rollbacks in the commit history. Rollbacks could be prevented by using git tags instead of git branches as reference, but are less practical.
