About

This rule detects potential Docker socket enumeration activity by monitoring processes that attempt to interact with the Docker socket file (/var/run/docker.sock). Docker socket enumeration is a common technique used by attackers to interact with the Docker daemon and perform various operations, such as creating, starting, stopping, and removing containers. Attackers may abuse Docker socket enumeration to gain unauthorized access to the host system, escalate privileges, or move laterally within the environment.
