Routers:

And what they do

Routers Are Targets:

Routers control access from every network to every network.

They advertise networks and filter who can use them, and they are potentially a hackers best friend.

Router security is a critical element in any security deployment.

By their nature, routers provide access and, therefore, you should secure them to reduce the likelihood that they can be directly compromised.

You can refer to other documents that have been written about security, which provide more detail on the following subjects:

• Locking down Telnet access to router
• Locking down Simple Network Management Protocol (SNMP) access to a router
• Controlling access to a router through the use of Terminal Access Controller Access Control System Plus (TACACS+)
• Turning off unneeded services
• Logging at appropriate levels
• Authentication of routing update
