AI Agent Security: Why Container Isolation & Linux RBAC Beat AI Firewalls | Kernel-Level Access Control

Container isolation (namespace + cgroup), strict RBAC, stripped Linux capabilities, and SELinux/AppArmor MAC profiles provide deterministic guarantees that semantic AI parsing cannot. Agents with no .env file read permission cannot exfiltrate .env files, regardless of how they’re prompted.
