Welcome to Comp 370.

"Security requires a particular mindset. Security professionals - at least the good ones - see the world differently. They can't walk into a store without noticing how they might shoplift. They can't use a computer without wondering about the security vulnerabilities. They can't vote without trying to figure out how to vote twice. They just can't help it."
-Bruce Schneier

Catalog Descritpion: An introduction to the concepts and techniques used for secure network communications. This course examines how security is defined at the cryptographic level, and how basic cryptographic algorithms can be used to construct secure network protocols. Topics covered may also include cryptocurrencies, access control, vulnerabilities found in networking protocols and how to answer common questions on computer security.

Course Textbook

There is no required textbook for the course. Over the course of the semester, I will recommend readings extracted from a variety of sources, some oe which will be posted here.

The stuff that we discuss on networks comes from:

• Computer Networking: A Top-Down Approach (7th Edition), by Jim Kurose and Keith Ross. I ordered the book at the library and it will be on reserve for the remainder of the semester. Do not feel like you have to buy the book, it's big, expensive, and we will only cover some of the chapters.

Additional references

Additional stuff on related topics will be added here.

• Diagrams of IPsec that I showed in class
