chapter.

10.6.1 Guidelines For Enhancing Security With Your Firewall

Step 1 Change the default password via web configurator.
Step 2 Think about access control before you connect to the network in any way.
Step 3 Limit who can access your LTE Device.
Step 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.
Step 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.
Step 6 Keep the firewall in a secured (locked) room.
