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 security develop risk management plan design network security policies analyse and plan solutions to compromised networks and design incident response evaluate security information and use it to plan suitable control methods and countermeasures add network controls according to system security policies procedures and risk management plan
Context of and specific resources for assessment	Assessment must ensure access to site or prototype where network security may be implemented and managed network support tools currently used in industry organisational security policies manufacturer recommendations and security standards 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 management of network security in a range of complex security situations review of documentation prepared by candidate to manage network security
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
