Extra Credit 3

Due: November 5, 2025
Points: 30

Short Answer

Answer these questions in one or two sentences.

1. (10 points) Find a news article or blog post that describes something about security that is incorrect. Submit the article or post (a URL or a DOI that enables us to read the article or post is sufficient) and explain why it is incorrect.

Longer Answer

Remember to write clearly (if you need help, go to the Writing Center on campus) and justify your answers!

2. (20 points) As encryption conceals the contents of network messages, the ability of intrusion detection systems to read those packets decreases. Some have speculated that all intrusion detection will become host-based once all network packets have been encrypted. Do you agree? Justify your answer. In particular, if you agree, explain why no information of value can be gleaned from the network; if you disagree, describe the information of interest.
