BN305 - Virtual Private Network

Credit Points: 15 credit points

Workload: 48 hours

Prerequisite: BN200 Network Security Fundamentals

Co-requisite: N/A

Aims & Objectives

This is a sixth trimester core unit out of a total of 24 units in the Bachelor of Networking (BNet). This unit addresses the BNet course learning outcomes and complements other courses in a related field by developing students’ specialised knowledge in virtual private networks and applying critical skills in networking equipment such as router, switch and server. For further course information refer to: This unit is part of the AQF Level 7 (BNet) course.

This subject provides students with the knowledge and advanced professional skills to manage and maintain a VPN. It also provides students with the knowledge and skills to deal with both MPLS and MPLS VPN architectures. Students will also obtain further knowledge and experience in building, implementing and managing VPN architecture and security.

Unit topics include:

  • Overview of VPN in security context, its characteristics, requirements and architecture
  • SSL VPN protocols and configurations
  • Internet Key Exchange Protocol version 1 and 2
  • IKE v1 & 2 and ISAKMP
  • Site-to-Site IPsec VPN Operations 
  • VPN routes management/handling at gateways 
  • Overview of MPLS VPN Technology
