The Enterprise Firewall is Dead (graded)
A popular computer network publication stated at one time that the enterprise firewall was dead.

Week 7

Intrusion Detection (graded)

Your organization’s business manager has read an article about how intrusion detection systems can help deter hackers.

Since an IDS can help deter hackers, does this make it a worthwhile project, or is there some reason to be wary? Specific to this example, how do you respond to ad hoc security requests like this? In general, how can you keep requests like this in check


Secure as a Car (graded)

Engineering software is like engineering a car; if one were so inclined, there could be a completely bug- and security-free application. Do you agree with this? Why or why not?


Week 2 You Decide
