Module Description: Network security is the activity associated with maintaining the confidentiality, integrity and availability of data traversing a network infrastructure. In this module, the learner will evaluate Internet security and encryption, firewalls, sniffing and packet crafting, Virtual Private Networks (VPNs), IPv6 security and Network Intrusion Detection and Response Systems (NIDRS).
 
Learning Outcomes
On successful completion of this module the learner will be able to:
# Learning Outcome Description
LO1 Identify and critically assess threats to network security, and data loss.
LO2 Install, configure, and evaluate firewalls in terms of their security effectiveness.
LO3 Configure and appraise Network Intrusion Detection and Response Systems (NIDRS).
LO4 Explain, install and configure Virtual Private Network (VPN) technology.
LO5 Evaluate the security of Internet Protocol version 6 (IPv6) Systems

Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
