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 ability to: evaluate network security system requirements design, implement and verify network security systems using layer 2 and layer 3 devices mitigate treats to network security configure VPNs for secure connectivity evaluate and implement NFP. |
Context of and specific resources for assessment | Assessment must ensure access to: site or prototype where network security may be evaluated and tightened hardware and software organisational guidelines, procedures and policies computers hardware and software LAN and WLAN internetwork technologies hardware and software security technologies appropriate learning and assessment support when required modified equipment for people with special needs. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: direct observation of the candidate installing, configuring and testing a new or updated network evaluation of documentation prepared by the candidate outlining testing procedures, test results, recommendation to network changes and completion records verbal or written questioning of required knowledge. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
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.
Threats may include: | denial of service (DoS) IP spoofing media access control (MAC) spoofing port scanning sniffing. |
Network resources may include: | company information corporate secrets data financial data personal information. |
Remote access connectivity features and benefits may include: | flexible and cost-effective licensing lower desktop support costs reduced cost and management complexity threat protection. |
EasyVPN benefits may include: | deployment flexibility easy to use and maintain enhanced interoperability increased productivity. |
