What is a Kubernetes PodSecurityAdmission (PSA) policy and what are its three policy levels?

Accepted Answer

PodSecurityAdmission (PSA) enforces Pod Security Standards at the namespace level. The correct answer outlines three policy levels: Privileged, Baseline, and Restricted, which are applied via namespace labels. This is accurate because PSA uses these levels to control pod security. Other options are incorrect as they misrepresent PSA's purpose.
