Which of the following is a weak spot in your network that can render your firewall ineffective?

A.
dial out modems

B.
routers

C.
gateways

D.
packet filters

E.
None of the above.

Explanation:
An important key to the success of a firewall is ensuring employees use it! This can require quite the sales job. In order to get buy-in (hopefully going from top management down through the ranks) it is necessary (in our organization anyway) to explain to people why what they want to do is a bad thing for the corporate network. One of the bad things people will want to do is install modems on PCs that are attached to the WAN and use them for “dial-out only”. It is a challenging task to convince them that doing this DOES create a risk, even if they are using a non-DID phone line. (Especially if the WAN has tens of thousands of nodes spread across a geographically huge area.)
