Ensure the named_t Process Type is Not in Permissive Mode
Descrição
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.
Como é verificado
Método de auditoria: Comando 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- Saída esperada
compliant
Como é corrigido
Método de correção: Orientação ou patch de infraestrutura
