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

identify threats to perimeter security

develop design for a secure perimeter

deploy perimeter to meet security requirements

design and configure advanced features of perimeter devices to provide additional services

design and configure an integrated VPN solution

conduct exhaustive testing of perimeter

Context of and specific resources for assessment

Assessment must ensure access to

site or prototype where perimeter security may be implemented and managed

perimeter devices

organisational security requirements

appropriate learning and assessment support when required

Where applicable physical resources should include equipment modified 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

verbal or written questioning to assess candidates knowledge of emerging security issues security features of hardware and software limitations in vendor solutions operating systems and software

direct observation of candidate demonstrating deployment and configuration of a security perimeter

direct observation of candidate conducting testing of secure perimeter

evaluation of report that outlines testing procedures test results and changes made as a result of testing

evaluation of design and implementation of system in terms of performance and suitability for business needs

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

Range Statement
