Ensure that privileged containers are not used

KritičnaNivo 1Automatskadocker

Opis

A privileged container gets all capabilities and device access and can trivially take over the host. Flags containers with HostConfig.Privileged true. 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.Privileged}}' $ids) || exit 1; bad=$(printf '%s\n' "$out" | awk '$2=="true" {print $1}'); [ -z "$bad" ] && echo compliant || printf '%s\n' "$bad"

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

Redeploy without --privileged (compose: remove 'privileged: true'); grant only specific capabilities or devices that are required.
