Ensure that docker.socket file permissions are set to 644 or more restrictive

高级别 1自动化docker

说明

The docker.socket 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.socket, /lib/systemd/system/docker.socket, /etc/systemd/system/docker.socket) with permission bits outside 644; not applicable when none exists.

检查方式

审计方法: Shell 命令

shell

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

预期输出: compliant
