• 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.

• Projects include Volcano, K3s, Confidential Computing, Crosslit, Cuver, Vorteil, Box, Rootless Containers, and Trial
• Use cases range from managing Kubernetes clusters at the edge to auto-scaling based on events to creating custom operating systems for specific workloads
• Volcano is for scheduling resource-intensive workloads, K3s is a lightweight Kubernetes distribution for the edge, and Confidential Computing provides encryption and security for running workloads without revealing information to cloud providers
• Cuver allows for managing virtual machines with Kubernetes, Crosslit enables running web assembly modules with Kubernetes, and Vorteil creates custom operating systems for specific workloads
• Box is a Docker container that acts like a VM, Rootless Containers allows running containers as root users without compromising the host, and Trial is a container registry with a focus on high performance and P2P distribution
