Runtime Security

Overview

Runtime security protects workloads during execution by monitoring behavior, enforcing policies, and detecting anomalies.

Runtime Controls

• System call monitoring
• Container escape detection
• File integrity monitoring
• Runtime network policy enforcement

Practical Example

Runtime platforms can alert when a container launches an unexpected shell process in production.

Production Example

High-sensitivity environments commonly enforce read-only root filesystems and block privileged container execution.

Common Pitfalls

• Relying only on build-time scanning
• Alerting without clear triage procedures
• Excessive runtime exceptions weakening policy

Key Takeaways

• Runtime security complements build-time controls.
• Behavioral detection improves threat visibility.
• Policy discipline is required for effective protection.
