Security protects applications, services, and data from unauthorized access, misuse, disruption, and compromise. Kubernetes deployments require security decisions before production, because weak container or cluster configuration can expose the host and organization. section 13.10 section 13.2
A practical Kubernetes security posture combines:
- Avoiding root and privileged containers, which can enable container escape and host takeover. section 13.10
- Configuring roles, role bindings, admission controls, image scanning, and encrypted network traffic. section 13.3
- Using Anthos Configuration Management and Gatekeeper policies to enforce cluster requirements consistently. section 13.10 section 13.3
- Treating virtual machines and containers as different systems with distinct failure and attack surfaces; neither is automatically secure. section 13.2
- Adding trusted-image deployment controls, security-optimized node updates, network isolation, TLS, and identity-based policies. section 15.1.5
Production cluster baseline
A production cluster can combine ACM-managed Roles and RoleBindings, Gatekeeper constraints, container vulnerability scanning, binary authorization for trusted images, and Anthos Service Mesh for isolation, TLS, and policy-driven identity security. section 13.10 section 15.1.5
