Container Security Issues

Misconfigured containers running as root, with excessive capabilities, privileged mode, or mounting sensitive host paths can allow container escape. This gives attackers access to the underlying host and other containers.

Overview

Container security encompasses multiple layers: base image vulnerabilities, runtime configuration, orchestration security (Kubernetes), and network policies. Misconfigurations such as running as root, using privileged mode, mounting the Docker socket, or exposing the Kubernetes API can lead to container escape and full infrastructure compromise.

Impact

Container escape to host OS, lateral movement between containers, access to host filesystem and network, cluster compromise.

Remediation

Run containers as non-root, drop all unnecessary capabilities, avoid privileged mode, use read-only filesystems, scan images for vulnerabilities, and implement network policies.

Run containers as non-root users

Drop all unnecessary Linux capabilities

Never use privileged mode in production

Use minimal base images and scan for CVEs

Implement Kubernetes Network Policies

Enable Pod Security Standards/Admission
