Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

VU23213 - Utilise basic network concepts and protocols required in cyber security

Course Description

In this course you will gain the skills and knowledge required to recognise the key features that make up the network security for an organisation.
It required the ability to investigate threats and mitigation techniques, network security models, administration protection and user access methods, introduction to firewall setup and configuration, intrusion prevention and intrusion detection systems (IPS/IDS) and software used to protect an organisation.

Learning Outcomes

On successful completion of this course you will have developed and applied the skills and knowledge required to demonstrate competency in the above elements. 

Details of Learning Activities

This unit describes the performance outcomes, skills and knowledge required to comprehend how data travels around the internet. It includes the function and operation of protocols such as Open System Interconnection (OSI) and Transmission Control Protocol/Internet Protocol (TCP/IP) suite and devices that facilitate data transfer. The exposure to these protocols is at an intermediate level in this unit. The unit applies to individuals working as cyber security technicians and supports their ability to detect breaches in security infrastructure.

In addition, students will become proficient in securing networks through the use of AAA modules, Zone-Based Firewalls, designing and deploying stand-alone and managed wireless networks, setting up VPNs, implementing switchport solutions, and deploying Adaptive Security Appliances.

Learning activities may be modified during the semester to meet the needs of students in the current program.

Activities will come from a range of the following:

  • Classroom and online presentations
  • Classroom and Laboratory Activities and Activity Tasks
  • PowerPoint presentations
  • Internet research
  • Assessments/Portfolios
