Legacy Policy Archive - Modernized for 2026
This legacy policy has been modernized to align with 2026 enterprise IT and cybersecurity standards, mandating Kubernetes/Container hardening, eBPF telemetry, and immutable infrastructure patterns.
INFRASTRUCTURE HARDENING POLICY
Approval Date August 22, 2026 Approved By Enterprise Security Council Purpose The organization’s IT infrastructure will be hardened according to this policy to minimize vulnerabilities across traditional, cloud-native, and containerized environments.
-
Overview Hardening secures a system by reducing its attack surface. This policy enforces modern infrastructure paradigms, emphasizing immutable infrastructure, zero-trust architectures, and advanced telemetry.
-
Scope This policy applies to all infrastructure components: Servers, Cloud Environments, Kubernetes Clusters, Containers, Networking Equipment, and Databases.
-
Immutable Infrastructure & Host Security
- Infrastructure must be deployed as code (IaC) and follow immutable infrastructure patterns. Servers and containers should be replaced rather than updated in place.
- Host Operating Systems must be minimal, purpose-built container operating systems (e.g., Bottlerocket, Flatcar) where applicable.
- Unnecessary services, ports, and default accounts must be disabled or removed.
- Access to underlying compute nodes is restricted. SSH access should be disabled in favor of centralized control planes and systems manager sessions.
- Kubernetes and Container Hardening
- Container images must be scanned for vulnerabilities and signed before deployment.
- Containers must run with least privilege. Root access within containers is strictly prohibited (non-root users only).
- Kubernetes clusters must enforce strict Network Policies to isolate namespaces and pod-to-pod communication.
- Pod Security Admission (PSA) or policy engines (e.g., OPA Gatekeeper, Kyverno) must be implemented to enforce security context constraints.
- Secrets must not be stored in environment variables or image layers; use native secret management or external vaults.
- eBPF Telemetry and Observability
- Deep system and network visibility must be achieved using eBPF-based telemetry (e.g., Cilium, Tetragon).
- eBPF sensors will monitor system calls, network flows, and execution traces in real-time with minimal overhead.
- Traditional event logging is supplemented by centralized, AI-driven observability platforms to detect anomalies and advanced persistent threats (APTs).
- Development Host & Pipeline Security
- Development, staging, and production environments must maintain parity in security controls.
- CI/CD pipelines must integrate automated security checks (SAST, DAST, SCA).
- Development data must be heavily sanitized or replaced entirely with synthetic data.
- Network & Boundary Security
- Zero-Trust Network Access (ZTNA) replaces traditional perimeter VPNs.
- Micro-segmentation is enforced at the network and application layers.
- Intrusion Prevention Systems (IPS) and Web Application Firewalls (WAF) must be deployed for all exposed services.
- Vulnerability Scanning & Penetration Testing
- Continuous automated vulnerability scanning is required for all code, container images, and infrastructure.
- Penetration testing (including automated attack simulation) is conducted annually and after significant architectural changes.
- Enforcement Breach of this policy may result in disciplinary action up to and including termination.
