+      Tracee is a Runtime Security and forensics tool for Linux. It is using

+      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.
