Ensure that the host's IPC namespace is not shared

VisokaNivo 1Automatskadocker

Opis

Sharing the host's IPC namespace exposes host shared memory segments and semaphores to the container. The audit inspects every running container (docker ps -q) and prints the offending names; a host with no running containers is compliant.

Kako se proverava

Metod provere: Komanda ljuske

shell

ids=$(docker ps -q) || exit 1; [ -z "$ids" ] && { echo compliant; exit 0; }; out=$(docker inspect --format '{{.Name}} {{.HostConfig.IpcMode}}' $ids) || exit 1; bad=$(printf '%s\n' "$out" | awk '$2=="host"{print $1}'); [ -z "$bad" ] && echo compliant || printf '%s\n' "$bad"

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Redeploy without --ipc=host (compose: remove 'ipc: host').
