Once again, it’s customary to include the post that I did for last year’s lecture on “Facebook Security & Privacy“.
Sometimes, “Security” is inversely proportional to “Privacy”. E.g. Airport tightened security reduces people’s privacy. In contrary, the more privacy people want, the less secure their data will be.
Chiang Kai went on to talk about Code Injection. It’s really quite fascinating. He did warn us that there are IT security laws in Singapore and therefore we shouldn’t try it at home. Err… ok.
Even though I have posted this in my previous post, I still think this is a good refresher.
Basic Security Objectives
- Protect from eavesdropping
- Protect from modification
- Protect from denial of services
