Ensure directed_broadcast is disabled

SedangLevel 1Otomatisaix

Deskripsi

The directed_broadcast parameter determines whether or not the system allows a directed broadcast to a network gateway. The directed_broadcast parameter will be set to 0, to prevent directed broadcasts being sent network gateways. This would prevent a redirected packet from reaching a remote network. Audit: `no -o directed_broadcast` must report 0.
