COMP 3261: Internet and Security Issues

This course presents the most practical of Internet/Intranet technologies and techniques to students. It covers Internet protocols, addressing and architecture, Intranet and Extranet design, installation and management, as well as all aspects of Internet/Intranet security and user/data authentication.

Objectives

Upon completion of this course, students will be able to:

  • Identify and classify particular examples of attacks.
  • Classify computer network vulnerabilities and types of attacks.
  • Define security goals and their meanings.
  • Explain useful tools commonly used by an attacker.
  • Explain common techniques used for launching the Denial of Service and Distributed Denial of Service attacks, as well as techniques to prevent them.
  • Explain the characteristics of viruses, worms and malware.
  • Explain the basic concepts and techniques for protecting and designing a private network.
  • Identify types of firewall implementation suitable for differing security requirements.
  • Apply and explain simple filtering rules based on IP and TCP header information.
  • Distinguish between firewalls based on packet-filtering routers, application level gateways and circuit-level gateways.
  • Compare and contrast symmetric and asymmetric encryption systems and their vulnerability to attack, and explain the characteristics of hybrid systems.
  • Explain what is meant by data integrity, and give reasons for its importance.
  • Describe the use of hash functions, and explain the characteristics of one-way and collision-free functions.
  • Explain the role of third-party agents in the provision of authentication services.
  • Explain some widely-used techniques and protocols for secure communications.
  • Discuss the effectiveness of passwords in access control and the influence of human behaviour.
  • Be aware of future trends in the field of network security.
