TMA-LXD-HTTPS-ADDRESS

Ensure the LXD remote API is not listening on all interfaces

높음레벨 1자동lxd

설명

core.https_address exposes the LXD REST API (full control of every instance and the host) over the network. The audit reads it with "lxc config get core.https_address" and passes when it is unset (local unix socket only) or bound to a specific address; it fails on wildcard binds such as [::], 0.0.0.0 or a bare :8443. The lxc client must reach the daemon (run as root or a member of the lxd group).

감사 방식: 셸 명령

shell

lxc info >/dev/null 2>&1 || exit 1
v=$(lxc config get core.https_address 2>/dev/null) || exit 1
case "$v" in
  "[::]"*|0.0.0.0*|:*) echo "remote API listens on all interfaces: $v"; exit 1 ;;

echo compliant

예상 출력: compliant

조치 방법

조치 방식: 가이드 또는 인프라 패치

If remote access is not needed: lxc config unset core.https_address. Otherwise bind to the management interface only, e.g. lxc config set core.https_address 10.0.0.5:8443, and restrict port 8443 with the host firewall.
