Monitoring and Incident Response

Monitoring and Incident Response

Registry monitoring detects security incidents and operational issues. Authentication failures indicate potential attacks. Unusual pull patterns suggest data exfiltration. Push failures may indicate corruption or attacks. Performance degradation affects availability. Comprehensive monitoring enables rapid incident detection and response.

Security event correlation identifies complex attack patterns. Failed authentication followed by successful access suggests compromised credentials. Multiple vulnerability scans followed by pulls indicate reconnaissance. Rapid pulls of many images suggest supply chain attacks. Event correlation requires integration with SIEM systems and security analytics platforms.

Incident response procedures specific to registries enable rapid containment. Revoking compromised credentials prevents continued access. Quarantining suspicious images prevents deployment. Registry rollback recovers from corruption. Clear communication channels notify affected teams. Post-incident analysis prevents recurrence through improved controls.

Container registry security forms a critical component of container supply chain protection. Strong authentication, comprehensive scanning, secure distribution, and continuous monitoring create defense in depth against registry attacks. The next chapter explores runtime security controls that protect containers during execution.## Runtime Security and Container Isolation

Container runtime security protects applications during execution, when they're most vulnerable to attacks. While secure images provide a good foundation, runtime protections prevent exploitation of application vulnerabilities and contain potential breaches. This chapter explores comprehensive runtime security strategies including Linux security modules, capability management, seccomp profiles, and runtime monitoring. We'll implement practical security controls that balance protection with application functionality.
