When computers are connected to the Internet, there is no clear boundary between network security and computer security. Nevertheless, this class will focus on issues that are most related to how computers can store and communicate data securely. We’ll focus on securing network protocols by applying concepts from cryptography, such as symmetric key and public key ciphers, secure hashes, key distribution, authentication, and digital signatures.  This course will also cover intrusion detection and firewalls, as they are essential for defending a network.

This 4-credit course is part of the Cybersecurity Foundations Certificate sequence.  Although this course can be taken as a stand-alone offering, it is also designed to integrate with (and be a companion to) the program Advanced Computing and Machine Learning (12 credits, winter quarter).

There will be lectures, hands-on labs, homework assignments, and tests.
