Security Automation and Tooling

Compliance frameworks tell you what to enforce. CIS says "restrict privileged containers," PCI-DSS says "log all access to cardholder data," SOC 2 says "implement logical access controls." The frameworks covered earlier in this module define the requirements. The harder question is how to enforce those requirements continuously, across every cluster, without a human reviewing every deployment.

That is where security automation comes in. The Kubernetes ecosystem has matured a rich set of open-source tools that automate compliance enforcement across the entire workload lifecycle. These tools fall into four categories, each covering a different phase: policy-as-code engines that block misconfigurations at deploy time, CIS benchmarking tools that audit cluster configuration, continuous scanners that watch running workloads for vulnerabilities, and runtime detectors that catch threats through syscall monitoring.
