The 8 Pillars of a Secure Container Platform

The 8 Strategic Pillars of a Secure Container Platform

A resilient platform does more than just run apps; it governs how those apps live and behave. These pillars map directly to NIST SP 800-190 standards to reduce the impact of modern cyber threats.

1. Supply Chain Trust & Software Provenance

  • The Risk: "Shadow Code" or tampered artifacts entering production. If you cannot verify the origin and integrity of your code, all other security tools can be bypassed.
  • The Use Case: Implementing a mandatory verification policy where every container image must be validated before it is allowed to run.
  • Platform Value: The platform provides a tiered approach to trust. You can start with Image Digests (Immutable Hashes) to ensure content hasn't changed. To verify origin, the platform integrates with Trusted Artifact Signer to sign and store keys. Enforcement is then handled via Sigstore on OpenShift or through RHACS admission controllers, ensuring only authorized, signed code is ever allowed to start.

2. Hardened Configuration & Host Isolation

  • The Risk: "Container Escape." If a container is misconfigured (for example, running with root privileges), an attacker can break out of the container and take control of the underlying server.
  • The Use Case: Enforcing a "Secure by Default" posture. The system automatically blocks dangerous permissions and prevents containers from accessing the host operating system.
  • Platform Value: OpenShift is pre-hardened with Security Context Constraints (SCC) and Red Hat Enterprise Linux CoreOS. These native guardrails enforce SELinux mandatory access controls and strip away administrative privileges automatically, providing strict isolation at the kernel level without manual effort.

3. Identity Governance & Least Privilege

  • The Risk: Credential sprawl and over-privileged accounts. If a single administrator account is compromised in an unmanaged environment, an attacker can take over the entire infrastructure.
  • The Use Case: Centralizing access control and ensuring that both users and automated services have only the minimum permissions needed to perform their tasks.
  • Platform Value: The platform integrates natively with enterprise identity systems (LDAP, AD, OIDC). It enforces granular Role-Based Access Control (RBAC) out of the box, ensuring that "Who did what" is always traceable and permissions are scoped to specific projects rather than the whole cluster.

4. Dynamic Micro-Segmentation & Visibility

  • The Risk: "Lateral Movement." In a flat network, if an attacker breaches one minor application, they can move freely to find and attack sensitive databases or internal APIs.
  • The Use Case: Building a segmented environment where application traffic is restricted to only what is necessary for business logic.
  • Platform Value: The platform provides the capabilities for NetworkPolicies, AdminNetworkPolicies, and BaselineAdminNetworkPolicies to control traffic flow. For visibility, the Network Observability Operator provides flow analysis, while RHACS goes a step further by visualizing the actual traffic graph and automatically generating the recommended network policies based on observed application behavior.

5. Resource Integrity & Service Availability

  • The Risk: "Denial of Service (DoS)." A buggy application or a malicious process consumes all available CPU and RAM, causing your critical business services to crash.
  • The Use Case: Guaranteeing "Quality of Service" (QoS). You ensure that your most important applications always have enough resources to run, regardless of other activity on the cluster.
  • Platform Value: The platform acts as a digital governor through native Resource Quotas and LimitRanges. It ensures that security agents and critical business apps always have the resources they need to remain stable, even during an application-level surge or attack.

6. Continuous Vulnerability Exposure & Compliance Lifecycle

  • The Risk: "Vulnerability Decay" and "Configuration Drift." Security is not a one-time event; software that is secure at the moment of deployment can become a liability overnight as new exploits are discovered. Furthermore, manual changes to cluster settings can silently move the platform out of a compliant state.
  • The Use Case: Shifting from "point-in-time" manual audits to "Continuous Visibility" and automated, daily verification of the entire security posture.
  • Platform Value: The platform provides a proactive defense layer through the native Compliance Operator, which automatically checks the infrastructure against NIST benchmarks every 24 hours. When combined with the integrated vulnerability scanning in the console and Quay, it moves beyond simple list-making to Risk Prioritization—identifying which vulnerabilities are actually exposed to the network and require immediate action.

7. Active Behavioral & System Integrity Defense

  • The Risk: "Silent Persistence." Traditional scanners cannot see "fileless" attacks, unauthorized system file changes, or malicious activities (like crypto-mining) that happen while a container is running.
  • The Use Case: Real-time detection and automated response to suspicious behavior or unauthorized modifications to the underlying platform.
  • Platform Value: The File Integrity Operator monitors the platform’s core files, while Advanced Cluster Security (ACS) watches runtime behavior. If an anomaly is detected, the platform can automatically alert and terminate the compromised workload to stop the attack in progress.

8. Governance-as-Code & Immutable Auditing

  • The Risk: "The Audit Gap." Security settings change over time due to manual fixes, and missing logs or a lack of software transparency make it impossible to prove compliance during an audit.
  • The Use Case: Having one "Source of Truth" for security rules across all clusters and providing an automated, tamper-proof record for auditors.
  • Platform Value: The platform uses "self-healing" policies via RHACM and GitOps to revert unauthorized changes. Furthermore, it provides full software transparency by managing a Software Bill of Materials (SBOM) through the Trusted Profile Analyzer, allowing auditors to verify the composition of every running application instantly.
