Ensure that docker.socket file ownership is set to root:root

高等級 1自動化docker

說明

The docker.socket unit file must be owned by root:root so that unprivileged users cannot alter Docker behaviour. The audit stats every existing candidate path (/usr/lib/systemd/system/docker.socket, /lib/systemd/system/docker.socket, /etc/systemd/system/docker.socket); not applicable when none exists.

檢查方式

稽核方法: Shell 指令

shell

for f in /usr/lib/systemd/system/docker.socket /lib/systemd/system/docker.socket /etc/systemd/system/docker.socket; do [ -e "$f" ] || continue; o=$(stat -Lc '%U:%G' "$f") || exit 1; [ "$o" = root:root ] || { echo "$f $o"; exit 0; }; done; echo compliant

預期輸出: compliant
