13-2 Firewall
4. Don't enable any local service (such as SNMP or NTP) that you don't use. Any enabled service could
present a potential security risk. A determined hacker might be able to find creative ways to misuse the
enabled services to access the firewall or the network.
5. For local services that are enabled, protect against misuse. Protect by configuring the services to
communicate only with specific peers, and protect by configuring rules to block packets for the
services at specific interfaces.
6. Protect against IP spoofing by making sure the firewall is active.
7. Keep the firewall in a secured (locked) room.
