Overview of assessment

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

Evidence of the ability to:

monitor and administer security functions on the system, which may include use of third-party diagnostic tools

confirm knowledge of security features available in the operating environment.

Context of and specific resources for assessment

Assessment must ensure access to:

security policy

industry and organisational standards

live system

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:

ensuring security policy compliance

using security strategies to evaluate and report on system security and threats

review of:

audit report and recommendations prepared

virus checking process and schedule implemented

verbal or written questioning to assess candidate’s knowledge of security features within the operating environment.

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 non-English speaking background may need additional support.

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