Container Escape Vulnerability Testing: Breaking Out of Docker and Kubernetes Containers — 日本企業向けガイド

Container escapes — where an attacker breaks out of container isolation to access the host operating system — represent one of the most severe container security risks. Testing covers: privileged container configuration, capability misconfigurations, volume mount security (mounting sensitive host paths), kernel exploit potential, container runtime vulnerabilities, and Kubernetes pod security standard enforcement. A successful escape gives attackers access to all containers on the host and potentially the entire cluster.
