Pod Security Policies

Pod Security Policies (PSPs) are rules used in Kubernetes, a system for managing applications, to control what kind of containers can run and how. They define security guidelines, such as whether containers can run as root, access certain resources, or mount specific filesystems. By applying PSPs, administrators ensure that application containers follow security best practices, reducing vulnerabilities and protecting the system from malicious or accidental misconfigurations. Essentially, PSPs serve as a gatekeeper to enforce safe container behaviors within the cluster.
