Summary from the TLDR InfoSec newsletter

Gatekeeper enforces security policies in Kubernetes by using Constraints and ConstraintTemplates to control cluster access and prevent unauthorized actions. Administrators can define custom policies or use pre-built templates to enhance cluster security by leveraging Gatekeeper. However, misconfigurations in policy logic, such as omitting trailing slashes in Constraint values, can introduce security risks and allow for policy bypasses.
