Jane Smith is responsible for security at the ABC Company.  She has a moderate budget with which to purchase security solutions.  To date, she has installed a router-based firewall between the network and the outside world.  She also has a commercial virus scanner on every machine on the network.

What other actions might you recommend to her?  Would you recommend a different firewall?  Why or why not?  Would you recommend an Intrusion Detection System, and if so, where would you recommend she place it?
