Ensure TLS authentication for Docker daemon is configured

KritisLevel 1Otomatisdocker

Deskripsi

When the daemon listens on a TCP socket, anyone who can reach it controls the host unless TLS client verification is enabled. Compliant when no tcp:// host is configured, or when tlsverify, tlscacert, tlscert and tlskey are all set. The audit reads the running dockerd command line (ps) together with /etc/docker/daemon.json.

Cara pemeriksaan

Metode audit: Perintah shell

shell

args=$(ps -eo args 2>/dev/null) || exit 1; s=$(printf '%s\n' "$args" | grep '[d]ockerd'; cat /etc/docker/daemon.json 2>/dev/null); if printf '%s\n' "$s" | grep -q 'tcp://'; then for k in tlsverify tlscacert tlscert tlskey; do printf '%s\n' "$s" | grep -Eq -e "--$k|\"$k\"" || { echo "missing $k"; exit 0; }; done; fi; echo compliant

Output yang diharapkan: compliant

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

Configure "tlsverify": true, "tlscacert", "tlscert" and "tlskey" in /etc/docker/daemon.json (or the equivalent dockerd flags) for any tcp:// listener, or remove the TCP listener, then restart the Docker daemon.
