Broad knowledge related to emerging security issues with substantial depth in related weaknesses of installed network infrastructure

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 knowledge of emerging security issues security features of hardware and software limitations in vendor solutions operating systems and software

Assessment must confirm the ability to implement and manage security functions on a network

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

Live system

Network support tools

Context of and specific resources for assessment

Managing network security is a complex process involving internal and external threats and choices between a range of potential solutions With many small to medium enterprises joining larger organisations in providing both domestic and global ecommerce facilities it is increasingly important to provide secure networks This can only be done with a comprehensive plan that takes into account the whole organisation system as well as the network

Analysis involves participation in development of network security planning and implementation

The breadth depth and complexity covering planning and initiation of alternative approaches to skills or knowledge applications across a broad range of technical andor management requirements evaluation and coordination would be characteristic

The demonstration of competency may also require selfdirected application of knowledge and skills with substantial depth in some areas where judgement is required in planning and selecting appropriate equipment services and techniques for self and others

Assessment must ensure

Applications involve participation in development of strategic initiatives as well as personal responsibility and autonomy in performing complex technical operations or organising others It may include participation in teams including teams concerned with planning and evaluation functions Group or team coordination may also be involved

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 ICA Section

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

Assessment will usually include observation of real or simulated work processes and procedures andor 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

An individual demonstrating this competency would be able to

Demonstrate understanding of security in relation to network solutions

Describe in detail issues related to security in some key areas

Analyse and plan to solve compromised networks

Determine network security requirements

Apply theoretical scenarios in line with security and technical issues

Demonstrate skills in a range of complex security situations

Evaluate security information and use it for planning purposes

Take responsibility for the achievement of security outcomes

Maintain knowledge of industry products and services

Additionally an individual demonstrating this competency would be able to

Demonstrate understanding of a broad knowledge base incorporating theoretical concepts with substantial depth in some areas

Analyse and plan approaches to technical problems or management requirements

Transfer and apply theoretical concepts andor technical or creative skills to a range of situations

Evaluate information using it to forecast for planning or research purposes

Take responsibility for own outputs in relation to broad quantity and quality parameters

Take some responsibility for the achievement of group outcomes
