This section provides some technical background information about the topics covered in this
chapter.
13.6.1 Guidelines For Enhancing Security With Your Firewall
1 Change the default password via web configurator.
2 Think about access control before you connect to the network in any way.
3 Limit who can access your Device.
4 Don't enable any local service (such as Telnet or FTP) 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 Keep the firewall in a secured (locked) room.
