Assessment tool

Version 1.0
Issue Date: March 2024


This unit describes the skills and knowledge required to use software tools, equipment and protocols to implement a security system.

It applies to individuals who plan and implement networks, are involved in business budgeting, and determine and resolve network security threats.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence of the ability to:

evaluate network security system threats and requirements

mitigate attacks and configure firewalls

design and implement network security systems

implement a virtual private network (VPN) using security device management tool.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

summarise access control lists, configuration and troubleshooting

outline authentication protocols

explain encryption techniques

explain intrusion detection system (IDS) and intrusion prevention system (IPS)

clarify internet protocol (IP) and networking models

explain current wireless regulations, standards and certifications

describe local area network (LAN) or wide area network (WAN) implementations

summarise malicious attacks and prevention techniques

outline network management tools

explain network security prevention methods

explain procedures to configure, verify and troubleshoot:

switch with virtual local area networks (VLANs) and inter-switching communications

router

outline procedures to set up virtual private networks (VPNs)

explain routing protocols

explain threat and attack mitigation techniques

outline the use of command line interface to configure and test network elements

describe the common features of Terminal Access Controller Access-Control System Plus(TACACS+) and Remote Authentication Dial In User Service (RADIUS) authentication, authorisation and accounting (AAA) protocols.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the network industry, and include access to:

a site where network security may be evaluated and tightened

hardware and software

organisational guidelines, procedures and policies

computers

LAN or WLAN internet work technologies (hardware and software)

security technologies (hardware and software).

Assessors must satisfy NVR/AQTF assessor requirements.
