Falco

1. Falco is an open-source runtime security tool that monitors system behavior and detects abnormal activity, focusing on container and Kubernetes environments.
2. It uses rule-based detection to identify suspicious events, such as privilege escalation, network anomalies, and unauthorized file access.

1. Start Falco to monitor container runtime activity: falco -c /etc/falco/falco.yaml
2. Use Falco to detect abnormal system calls: falco -r /etc/falco/rules.yaml
