Why is immutable infrastructure important?

Immutability ensures that containers remain in a known-good state, making any modification a clear indicator of a potential security incident.

What is container drift?

Container drift occurs when a running container's state deviates from its original image through unauthorized file, binary, or configuration changes.

How does this skill help with security?

It provides specific detection rules and enforcement patterns to identify and block malicious activity inside containers in real-time.

Can this work with tools other than Falco?

Yes, it includes guidance for Kubernetes security contexts, Microsoft Defender for Containers, and custom shell-based verification scripts.

Security & Testing

Monitors and alerts on unauthorized modifications to running containers to maintain immutable infrastructure and detect security breaches.

This skill provides comprehensive guidance and implementation patterns for detecting container drift at runtime, a critical component of secure, immutable infrastructure. It enables Claude to assist in identifying unauthorized binary executions, filesystem changes, and configuration deviations using industry-standard tools like Falco and Kubernetes security contexts. By mapping detection techniques to frameworks like MITRE ATT&CK and NIST CSF, it helps security teams and DevOps engineers implement the DIE (Detect, Isolate, Evict) model to rapidly respond to potential compromises in cloud-native environments.
