Getting started with Kubernetes audit logs and Falco

As Kubernetes usage grows, integrating Kubernetes audit logs is vital for enhancing security strategies by providing visibility into cluster events and enabling detection of suspicious activities. Introduced in Kubernetes 1.11, audit logs capture key events like deployments and namespace deletions, which can be parsed by security tools such as Falco to alert on threats. Falco, an open-source runtime security tool, acts as a webhook backend to ingest these logs, offering real-time threat detection with customizable rules. Kubernetes audit logs allow security teams to track what happened, identify responsible users, and understand event timelines and locations, thus aligning with compliance requirements. Configuring audit policies lets users filter desired events, reducing unnecessary verbosity and potentially lowering costs, especially when using SaaS logging solutions. The integration of Falco as a threat detection engine is emphasized as a crucial step in enforcing Kubernetes security best practices and bridging the gap between perceived and actual cluster activities.
