Ensure that Docker server certificate file ownership is set to root:root
TinggiLevel 1Otomatisdocker
Deskripsi
The Docker server certificate file must be owned by root:root so that it cannot be replaced by unprivileged users. The path is taken from --tlscert on the dockerd command line or "tlscert" in /etc/docker/daemon.json (default /root/.docker/cert.pem); compliant when no such file exists (TLS not configured).
Cara pemeriksaan
Metode audit: Perintah shell
shell
args=$(ps -eo args 2>/dev/null) || exit 1; s=$(printf '%s\n' "$args" | grep '[d]ockerd'; cat /etc/docker/daemon.json 2>/dev/null); p=$(printf '%s\n' "$s" | sed -n -e 's/.*--tlscert[= ]\([^ ]*\).*/\1/p' -e 's/.*"tlscert"[[:space:]]*:[[:space:]]*"\([^"]*\)".*/\1/p' | head -n 1); [ -n "$p" ] || p=/root/.docker/cert.pem; [ -e "$p" ] || { echo compliant; exit 0; }; o=$(stat -Lc '%U:%G' "$p") || exit 1; [ "$o" = root:root ] && echo compliant || echo "$p $o"- Output yang diharapkan
compliant
Cara perbaikan
