Prose
Docker Enterprise docker.socket file ownership must be set to root:root.
High Severity
Verify that the docker.socket file ownership and group ownership is correctly set to root. docker.socket file contains sensitive parameters that may alter the behavior of Docker remote API. Hence, it should be owned and group-owned by root to maintain the integrity of the file. This file may not be present on the system. In that case, this recommendation is not applicable. By default, if the file is present, the ownership and group-ownership for this file is correctly set to root.
