Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 the ability to develop, implement and maintain basic security functionality for VPNs, LANs, WANs or WLANs To demonstrate competency in this unit the person will require access to: Network technical requirements Network infrastructure, including servers and security hardware and software |
Context of and specific resources for assessment | 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 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. |
Guidance information for assessment | 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 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 |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Ability to develop enterprise policies strategies and procedures Ability to undertake a network security risk assessment Ability to implement security strategies and configure network security software and hardware Implementing LAN, WAN, VPN and WLAN solutions Cost-benefit comparison Troubleshooting and debugging |
Required knowledge |
Security threats, including eavesdropping, data interception, data corruption, data falsification Authentication issues Organisational issues surrounding security Security perimeters and their functions Types of VPNs, including site-to-site, user-to-site internet traffic and extranets Function and operation of VPN concepts, including encryption, firewalls, packet tunnelling and authentication Common VPN issues, including bandwidth and dynamic security environment Network protocols and operating systems Security protocols, standards and data encryption Configuring routers and switches Cryptography LAN, WLAN and WAN TCP/IP protocols and applications Auditing and penetration testing techniques Screened subnets Virus detection software Audit and intrusion detection systems |
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. | |

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
