Incident response in Kubernetes with Sysdig's Activity Audit

Sysdig's Activity Audit, introduced in the Secure 3.0 release, enhances incident response and auditing capabilities in Kubernetes by correlating container and Kubernetes activity. This feature allows security teams to investigate and document all user, application, and Pod activity, addressing challenges in distributed environments where containers are ephemeral and data can disappear quickly. By capturing data such as executed commands, network connections, and Kubernetes API events, Sysdig provides a comprehensive audit trail that aids in compliance with standards like SOC 2, PCI, ISO, and HIPAA. The Activity Audit enables security operations centers (SOC) to identify abnormal behavior and respond swiftly to security incidents, while also supporting detailed post-mortem analyses. Through examples, Sysdig demonstrates how the tool can trace suspicious activities, such as unauthorized kubectl exec sessions, and provide insights into user actions and network interactions, thereby enhancing the overall security posture and visibility in Kubernetes environments.
