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 e-commerce 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 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. Assessment must ensure:
|
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.
|
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:
