Ensure dm-verity is configured

VisokaNivo 1Automatskabottlerocket

Opis

dm-verity provides transparent integrity checking of block devices using a cryptographic digest. Because dm-verity devices are read-only, filesystems mounted from the devices are also read-only. The audit requires dm-mod.create=root,,,ro,0, root=/dev/dm-0 and restart_on_corruption on /proc/cmdline. Run tmaegis on the host through the admin container root shell (sudo sheltie).

Kako se proverava

Metod provere: Komanda ljuske

shell

c=$(cat /proc/cmdline 2>/dev/null) || exit 1
bad=0
for w in 'dm-mod.create=root,,,ro,0' 'root=/dev/dm-0' restart_on_corruption; do
  printf '%s\n' "$c" | grep -Fwq -- "$w" || { echo "kernel cmdline lacks $w"; bad=1; }
done
[ "$bad" -eq 0 ] && echo compliant

Očekivani izlaz: compliant
