Ensure sensitive host system directories are not mounted on containers

YüksekDüzey 1Otomatikdocker

Açıklama

Mounting host system directories (/, /boot, /dev, /etc, /lib, /proc, /sys, /usr) lets a container read or change the host. Flags those directories mounted in any mode, and anything below them mounted read-write. The audit inspects every running container (docker ps -q) and prints the offending names; a host with no running containers is compliant.

Nasıl denetlenir

Denetim yöntemi: Kabuk komutu

shell

ids=$(docker ps -q) || exit 1; [ -z "$ids" ] && { echo compliant; exit 0; }; out=$(docker inspect --format '{{.Name}} {{range .Mounts}} {{.Source}}|{{.RW}}{{end}}' $ids) || exit 1; bad=$(printf '%s\n' "$out" | awk '{for(i=2;i<=NF;i++){split($i,a,"|"); if(a[1] ~ /^\/(boot|dev|etc|lib|proc|sys|usr)?$/ || (a[2]=="true" && a[1] ~ /^\/(boot|dev|etc|lib|proc|sys|usr)\//)) print $1" "a[1]}}'); [ -z "$bad" ] && echo compliant || printf '%s\n' "$bad"

Beklenen çıktı: compliant

Nasıl düzeltilir

Düzeltme yöntemi: Kılavuz veya altyapı yaması

Redeploy the container without bind mounts of sensitive host directories; if a file is truly needed, mount only that file read-only (-v /etc/foo:/etc/foo:ro).
