This course introduces the basics of cyber defense starting with foundational models such as Bell-LaPadula and information flow frameworks. These underlying policy enforcements mechanisms help introduce basic functional protections, starting with authentication methods. Learners will be introduced to a series of different authentication solutions and protocols, including RSA SecureID and Kerberos, in the context of a canonical schema. 
The basics of cryptography are also introduced with attention to conventional block ciphers as well as public key cryptography. Important cryptographic techniques such as cipher block chaining and triple-DES are explained. Modern certification authority-based cryptographic support is also discussed and shown to provide basis for secure e-commerce using Secure Sockets Layer (SSL) schemes.

TOP REVIEWS FROM CYBER ATTACK COUNTERMEASURES

by NSFeb 10, 2019

I like how Dr. Amoroso made some complicated concept sounds easy. I also love when he told us about the history of cyber security in this course.

by PTOct 8, 2021

Instructor makes it easy to understand and keeps it interesting. Especially enjoy the talks and due credits to the unsung hero's of the early cyber security scene.

by ECSep 11, 2021

Great info, well-chosen readings, wish there were more practice problems. Assignments and quizzes are good for a Coursera course, but not great.

by MHAug 12, 2020

Excellent!! You are a great teacher, and I learned a lot. I have already applied the knowledge gained to my business. Grazie mille.
