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 following is essential:

Assessment must confirm an understanding of the organisation's network security and access policies.

Assessment must confirm knowledge of the security features available in the operating environment and the ability to monitor and administer security functions on the network. This may include use of third-party diagnostic tools.

To demonstrate competency in this unit the following resources will be needed:

A live network with security restrictions

Security and access policies

Security information resources

Hardware and software that will improve security

Context of and specific resources for assessment

Security planning and monitoring aids in preventing intrusion into a network. With computers containing and manipulating significant data about our finances, purchasing habits and other private information, monitoring and administering network security is an ongoing challenge for organisations which collect and use such information.

This unit provides a starting point for monitoring and administering network security. Activities undertaken in this unit should be done in a closed-off LAN/WAN/WLAN and the skills developed not used on live open networks.

The breadth, depth and complexity of knowledge and skills in this competency would cover a broad range of varied activities or application in a wider variety of contexts most of which are complex and non-routine. Leadership and guidance would be involved when organising activities of self and others as well as contributing to technical solutions of a non-routine or contingency nature.

Assessment must ensure:

Performance of a broad range of skilled applications including the requirement to evaluate and analyse current practices, develop new criteria and procedures for performing current practices and provision of some leadership and guidance to others in the application and planning of the skills would be characteristic.

Applications may involve responsibility for, and limited organisation of, others.

Method of assessment

The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1.

Competency in this unit should to be assessed using summative assessment to ensure consistency of performance in a range of contexts. This unit can be assessed either in the workplace or in a simulated environment. However, simulated activities must closely reflect the workplace to enable full demonstration of competency.

Due to the inherent risks involved in activities such as dealing with the security of potentially sensitive information, it is strongly recommend that work and assessment be carried out on a system separate from the organisation's main field of network activity or in a simulated environment. Where a workplace context is used, specific control for security must be adhered to in all circumstances.

Assessment will usually include observation of real or simulated work processes and procedures and/or performance in a project context as well as questioning on underpinning knowledge and skills. The questioning of team members, supervisors, subordinates, peers and clients where appropriate may provide valuable input to the assessment process.

Guidance information for assessment

The interdependence of units for assessment purposes may vary with the particular project or scenario. Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICAD4043B Develop and present a feasibility report

ICAS5202B Ensure privacy for users

An individual demonstrating this competency would be able to:

Use detection tools to detect intrusion

Monitor and administer activities of users

Apply emergency solutions to a variety security problems

Interpret available information and request clarification where needed

Additionally, an individual demonstrating this competency would be able to:

Demonstrate understanding of a broad knowledge base incorporating some theoretical concepts

Apply solutions to a defined range of unpredictable problems

Identify and apply skill and knowledge areas to a wide variety of contexts, with depth in some areas

Identify, analyse and evaluate information from a variety of sources

Take responsibility for own outputs in relation to specified quality standards

Take limited responsibility for the quantity and quality of the output of others

Maintain knowledge of industry products and services
