Incident Response for Runtime Security Events

Incident Response for Runtime Security Events

Runtime security incidents require rapid response to contain potential breaches. Incident response procedures must account for container ephemerality and scale. Traditional incident response assuming persistent systems requires adaptation for containerized environments. Automated response capabilities become essential given the speed and scale of container deployments.

Container isolation during incidents prevents lateral movement while preserving evidence. Network policies can dynamically isolate compromised containers. Admission controllers can prevent new instances of compromised images. These automated responses contain incidents faster than manual intervention. However, automated responses require careful design to avoid service disruptions from false positives.

Forensic analysis in containerized environments presents unique challenges. Containers may be destroyed before analysis, losing valuable evidence. Runtime security tools must capture and preserve security-relevant data for later analysis. This includes system calls, network connections, file modifications, and process executions. Centralized storage ensures evidence availability even after container termination.
