Falco Runtime Security

Falco is an open-source, cloud-native runtime security solution designed to detect abnormal and malicious activity in Linux hosts, containers, and Kubernetes environments. It works by monitoring system calls and applying security rules to identify suspicious behavior in real time.

Features of Falco:

• Real-time detection of suspicious system and container behavior.
• Uses eBPF or kernel modules to monitor Linux system calls.
• Supports Kubernetes, containers, and bare-metal hosts.
• Rule-based detection engine with customizable security policies.
• CLI-based operation suitable for headless and IP-based environments.
• Integrates with SIEM, alerting, and monitoring systems.
