Introduction to Information Security

Information security is becoming increasingly important in today's networked world, and is impacting every aspect of our lives including fiance, healthcare, government, education, arts and entertainment. 

The object of this course is to teach the basic principles of information security from the perspective of providing security awareness and its best practices for the real world.

Topics include:

  • Motivation for security
  • Tools and techniques used by adversaries to gather information and launch attacks
  • Internet security, firewalls, basics of encryption and authentication, virus protection, secure credit card and bank transactions, wireless security, computer forensics, identity theft and protection, anti-phishing and biometric security

Content will be delivered via a combination of lectures and discussions in the class times and interactive exercises in the lab times.
