• Pod security is a built-in admission controller in Kubernetes that evaluates pod specifications against a predefined set of pod security standards.
• It provides policy standards to restrict pod privileges, reducing the surface area of attacks and making the cluster more secure.
• Pod security is simple and easy to use, with pre-defined standards that align with Kubernetes security best practices.
• Pod security policy, which is being deprecated, can be migrated to pod security using a well-defined process.
• Pod security does not support mutation, which is the ability to change Kubernetes resources server-side.
