Aims & Objectives

This is a third trimester core unit out of a total of 24 units in the Bachelor of Networking (BNet) and Bachelor of Engineering Technology (Telecommunications) BEngTech(Tel). This unit addresses the BNet and BEngTech(Tel) course learning outcomes and complements other courses in a related field by developing students’ knowledge and skills in network security.

This unit is part of the AQF Level 7 (BNet and BEngTech(Tel)) courses.

This unit provides students with a comprehensive overview of the field of network security, security risks and countermeasures associated with network connectivity. Students will gain knowledge and skills to understand, apply and manage network security. There are some activities designed to protect network data that include protecting the usability, reliability, integrity, and safety of network and data.

The unit will help students to identify common security vulnerabilities, threats and in depth analysis of these threats that network users often face. It will help students to respond to and recover from security incidents through exercises.

The content of this unit will cover the following areas:

  • Introduction to Network Security
  • Symmetric Encryption and Message Confidentiality
  • Public‐Key Cryptography and Message Authentication
  • Transport‐Level and IP Security
  • Intruders and Malicious Software

Learning Outcomes

At the completion of this unit students should be able to:

  1. Discuss the main security issues and emerging trends of information security;
  2. Identify common emerging threats, attacks, mitigation and countermeasures in networked information systems;
  3. Explain the major methodologies for secure networks and the threats they address;
  4. Identify and report network threats, select and implement appropriate countermeasures for network security;
  5. Use security policies to manage operational security, and then administer those policies to ensure compliance by users in an organization.

Levels of attainmentExtent covered
5The standard is covered by theory and practice, and addressed by assessed activities in which the students always play an active role, e.g. workshops, lab submissions, assignments, demonstrations, tests, examinations
4The standard is covered by theory or practice, and addressed by assessed activities in which the students mostly play an active role, e.g. discussions, reading, intepreting documents, tests, examinations
3The standard is discussed in theory or practice; it is addressed by assessed activities in which the students may play an active role, e.g. lectures and discussions, reading, interpretation, workshops, presentations 
2The standard is presented as a side issue in theory or practice; it is not specifically assessed, but it is addressed by  activities such as lectures or tutorials
The standard is not considered, there is no theory or practice or activities associated with this standard
