Question
Part 1: In each of the following scenarios, tell whether there is a violation of confidentiality, integrity, or availability, or some combination of the three. In addition, for each item, write a two- or three-sentence paragraph explaining why your answer is correct.
A/ Alex disables Barbara's router by logging in remotely with the manufacturer's default password.
B/ Mallory builds a WiFi jammer using plans she found on the Internet and jams wireless signals over a large part of her apartment building.
C/ Charlene uses a key logger to capture Darla's banking password.
D/ Eve rewrites the magnetic stripe on a gift card to change the amount from $10 to $100. (Adapted from an exercise in Bishop, Matt, Introduction to Computer Security.)
Part 2: Distinguish among vulnerability, exploit, threat, risk, and control mechanism (called "countermeasure" in chapter one of the text) in five brief paragraphs. If you do any research outside the textbook, which you are encouraged to do, be sure to cite your sources. You can see how to do that in An Example of Proper Writing in the "Required Reading" section.
