Ensure that the /etc/default/docker file permissions are set to 644 or more restrictively

MediumLevel 2Automateddocker

Description

/etc/default/docker (daemon start-up options) must have mode 644 or more restrictive. The audit flags any existing candidate path (/etc/default/docker) with permission bits outside 644; not applicable when none exists.

How it is checked

Audit method: Shell command

shell

for f in /etc/default/docker; do [ -e "$f" ] || continue; out=$(find "$f" -maxdepth 0 -perm /7133) || exit 1; [ -z "$out" ] || { echo "$f"; exit 0; }; done; echo compliant

Expected output: compliant

How it is fixed

Fix method: Shell command

shell

for f in /etc/default/docker; do if [ -e "$f" ]; then chmod 644 "$f" || exit 1; fi; done
