Question: Chiao Chien manages IT security for a school. Given the wide range of people who use the school's computers, it is difficult for Chien to prevent virus attacks. Chien has a reasonably good budget and has installed antivirus software on every machine. He also has a firewall that has all unneeded ports blocked, and there is a school policy prohibiting the downloading of any software from the Web. Consider the following questions:
¦ How secure do you think Chien's network is from virus attacks?
¦ What areas has Chien not secured?
¦ What recommendations would you make to Chien?
