This is a first trimester core unit out of a total of 12 units in GDNet/MNet/MEng(Tel). This unit addresses the course learning outcomes and complements other courses in a related field by developing students’ specialised knowledge in network security and applying critical skills in networking equipment such as router, switch and server. For further course information refer to: http://www.mit.edu.au/study-with-us/programs/master-networking, http://www.mit.edu.au/study-with-us/programs/master-engineering-telecommunications, http://www.mit.edu.au/study-with-us/programs/graduate-diploma-networking.

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, analyse, and compare 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 case studies/workshops.

The unit will cover the following areas:

  • Introduction of Network Security
  • Symmetric Encryption and Message Confidentiality
  • Public‐Key Cryptography and Message Authentication
  • Key Distribution and User Authentication
  • Transport‐Level Security
  • Electronic Mail Security
  • IP Security
  • Intruders
  • Malicious Software
  • Firewalls
  • Case studies


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

  1. Analyse and discuss the main security issues and emerging trends of information security
  2. Analyse and discuss common emerging threats, attacks, mitigation and countermeasures of networked information systems
  3. Explain the major methodologies for secure networks and what 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
  6. Demonstrate professional and ethical behaviour with regard to network security.


MIT is committed to ensure the course is current, practical and relevant so that graduates are “work ready” and equipped for life-long learning. In order to accomplish this, the MIT Graduate Attributes identify the required knowledge, skills and attributes that prepare students for the industry.

The level to which Graduate Attributes covered in this unit are as follows:

Ability to communicate Independent and Lifelong Learning Ethics Analytical and Problem Solving  Cultural Global Awareness Team work Specialist knowledge of a field of study


Colour coding Extent covered
                                The 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
  The 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
  The 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 
  The 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
