      Tracee is a Runtime Security and forensics tool for Linux. It is using
      Linux eBPF technology to trace your system and applications at runtime,
      and analyze collected events to detect suspicious behavioral patterns. It
      is delivered as a Docker image that monitors the OS and detects suspicious
      behavior based on a pre-defined set of behavioral patterns.
