Falco

Falco is an open-source, cloud-native security tool designed for runtime security and threat detection through behavioral activity monitoring. It effectively identifies anomalous behavior in applications and containers by analyzing system calls and Kubernetes audit logs, making it particularly useful for organizations aiming to safeguard their cloud-native environments. With its customizable rules engine, users can tailor security policies and alerts to meet their specific needs, enhancing their ability to detect runtime security incidents and receive real-time alerts. Falco is well-suited for monitoring containers, Kubernetes clusters, and cloud infrastructure for suspicious activities, integrating seamlessly with popular cloud-native tools and platforms. While it offers significant advantages such as being free to use and providing real-time threat detection, users should be aware that it can be complex to set up and configure, requires a solid understanding of system calls and Linux security, and may occasionally generate false positives.
