Hacking
Summary
Self-study questions
1. Criminals use proxy servers to hide their activity. Should we make it a crime to operate a proxy server or are there times when anonymity is desirable?
2. Do you mind servers like the one at SurveyGizmo.com gathering data on you?
3. Can you think of reasons you might want data to be gathered on you?
4. Do you pay attention to your Facebook privacy settings or did you just accept the default setting?
5. How do questions of privacy differ between cultures and political systems?
6. Who pays for aggregation of data about a user and what is the benefit?
