Security features for Kubernetes

P0 is an API-based integration that provides temporary access to sensitive Kubernetes resources, enhancing security while reducing operational friction. It automates privilege escalations, allowing teams to access resources like secrets and data only when necessary, and immediately revokes these privileges once they expire. P0 achieves this by creating roles and role bindings within Kubernetes clusters, using a service account with a long-lived token stored securely on P0's servers. Access can be unilaterally revoked by the organization by deleting the service account or secret object. The system employs a permission boundary to restrict unauthorized access, ensuring that even if P0 is compromised, attackers cannot escalate privileges beyond what's granted to P0. A custom admission controller prevents P0 from escalating its own permissions. For private clusters, P0 uses a reverse proxy to facilitate secure communication with the Kubernetes API, forwarding API payloads over a secure WebSocket connection.
