This unit will provide students with an understanding of: OSI security architecture; common information risks and requirements; operation of encryption techniques; digital signatures; public key infrastructure; authentication and non-repudiation; intrusion detection and response; firewall defence; privacy and ethics issues; security configurations to PC-based applications; and design of information systems with security compliance and security standards and protocols.


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

  1. describe OSI security architecture and apply common security standards and protocols for network security applications e.g. electronic mail, IP, web and network management;
  2. critically assess threats, vulnerabilities and risks to an organisations information assets and propose control technologies and techniques which can be applied to reduce the security risk;
  3. apply cryptographic techniques to develop methods to disguise information to ensure its integrity, confidentiality and authenticity;
  4. describe the ethical, legal and criminal issues relating to the security of information and computer networks both Wired and Wireless;
  5. implement cryptographic algorithms and security protocols to provide security over networks and the Internet using Vitual Private Networks;
  6. design system security against intruders and malicious software;
  7. apply security configurations to computer and network based applications.
  8. describe and apply firewall configurations to protect networks.
  9. implement network management protocols and security requirements.


NOTE: From 1 July 2019, the duration of all exams is changing to combine reading and writing time. The new exam duration for this unit is 2 hours and 10 minutes.
