Adding runtime threat detection to Google Kubernetes Engine with Falco

The blog post discusses enhancing the security of Google Kubernetes Engine (GKE) clusters by integrating Falco, a Cloud Native Computing Foundation project that provides runtime threat detection. Falco monitors system calls to detect suspicious activities within containers and hosts, offering over 80 rules to identify both external threats and deviations from industry best practices. The installation of Falco on GKE can be done via the Google Cloud Marketplace or Helm, with considerations for using eBPF probes due to the security constraints of GKE's default Container-Optimized OS. The blog provides detailed steps for deploying Falco and includes testing procedures to ensure Falco's alerts are functioning correctly, demonstrating its capability to detect unauthorized access attempts and modifications within containers. By implementing Falco, users can gain runtime insights that contribute to responsible cluster operation and enhanced security against potential threats.
