Elements and Performance Criteria
No information
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

May include but is not limited to people and technology interaction, storage and recovery of data, access to internal network, passwords/logons, access control lists, firewalls, black-hat hacking/cracking, confidentiality, integrity, availability, the perceived value of information to competitors and the malicious nature of internet crackers and an increase in internet usage

May include but is not limited to internal departments, external organisations, individual people and internal employees

May include eavesdropping, manipulation, impersonation, penetration, denial of service and by-pass, hackers, viruses using logging

Cost-benefit analysis

Assessment guidance
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 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 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. The interdependence of units for assessment purposes may vary with the particular project or scenario.

In the case of this unit, it could be assessed in a holistic manner with:

ICAA5056B Prepare disaster recovery and contingency plans

Resources

To demonstrate competency in this unit the person will require access to:

Network technical requirements
Network infrastructure, including servers and security hardware and software

Industry/vendor training
May include CISCO, Microsoft, IBM, Redhat

Role context
The breadth, depth and complexity covering planning and initiation of alternative approaches to skills or knowledge applications across a broad range of technical and/or management requirements, evaluation and coordination would be characteristic.
The demonstration of competency may also require self-directed 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.
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.

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 and/or 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
Maintain knowledge of industry products and services
