Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the ability to

evaluate network security system requirements

design implement and verify network security systems using layer and layer devices

mitigate treats to network security

configure VPNs for secure connectivity

evaluate and implement NFP

Context of and specific resources for assessment

Assessment must ensure access to

site or prototype where network security may be evaluated and tightened

hardware and software

organisational guidelines procedures and policies

computers

hardware and software LAN and WLAN internetwork technologies

hardware and software security technologies

appropriate learning and assessment support when required

modified equipment for people with special needs

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge The following examples are appropriate for this unit

direct observation of the candidate installing configuring and testing a new or updated network

evaluation of documentation prepared by the candidate outlining testing procedures test results recommendation to network changes and completion records

verbal or written questioning of required knowledge

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector workplace and job role is recommended where appropriate

Assessment processes and techniques must be culturally appropriate and suitable to the communication skill level language literacy and numeracy capacity of the candidate and the work being performed

Indigenous people and other people from a nonEnglish speaking background may need additional support

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge
