You’re interested in doing some work on your laptop at the local coffee shop, but you’re concerned with the security of the public wireless network. What can help protect your computer while you’re using this public network?

A) Two-factor authentication

B) DSL router

C) Personal firewall

D) Peer-to-peer networking

E) A big stick


The answer: C) Personal firewall
