TMA-DOCKER-3.2

Ensure that docker.service file permissions are appropriately set

AltaNivel 1Automatizadadocker

Descripción

The docker.service unit file must have mode 644 or more restrictive so that it cannot be modified by non-root users. The audit flags any existing candidate path (/usr/lib/systemd/system/docker.service, /lib/systemd/system/docker.service, /etc/systemd/system/docker.service) with permission bits outside 644; not applicable when none exists.
