  Falco is a cloud-native runtime security tool that detects unexpected
  application behavior and alerts on threats at runtime using eBPF. It is a
  CNCF graduated project that continuously monitors Linux kernel syscalls and
  compares them against configurable security rules to detect intrusions,
  privilege escalation, and other suspicious behaviors.

      The Falco Plugin API provides a C ABI interface for developing plugins
      that extend Falco with new event sources and field extractors. Plugins
      are shared libraries that implement the plugin API and can be loaded at
      runtime to add support for new data sources such as cloud audit logs,
      container activity, and custom event streams.
