Ensure the named_t Process Type is Not in Permissive Mode

НискаНиво 2Аутоматскаbind

Опис

In addition to setting the entire SELinux configuration in permissive mode, it is possible to set individual process types (domains) such as named_t into a permissive mode as well. The permissive mode will not prevent any access or actions, instead, any actions that would have been denied are simply logged. The audit runs semodule -l and fails when the permissive_named_t module is loaded.

Како се проверава

Метод провере: Команда љуске

shell

command -v semodule >/dev/null 2>&1 || exit 1
out=$(semodule -l 2>/dev/null) || exit 1
printf '%s\n' "$out" | grep -q permissive_named_t && echo 'named_t is permissive' || echo compliant

Очекивани излаз: compliant

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Perform the following to implement the recommended state: If the named_t type is in permissive mode; the customized permissive mode should be deleted with the following semanage command. # semanage permissive -d named_t
