Elements and Performance Criteria Pre-Content


Performance Criteria 

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

1. Determine business security requirements

1.1 Identify level of security required based on the business and commercial intent of the website

1.2 Identify whether password protection is needed for the site or part of the site

1.3 Decide minimum or maximum password protection solutions based on business requirements 

2. Ensure web server security

2.1 Ensure that web server  password is obscure and non-traceable

2.2 Install and maintain an effective intrusion detection system  according to business requirements

2.3 Ensure that user  accounts have only the required permissions on the server

2.4 Ensure that interpreters’ programs that run common gateway interfaces (CGIs) are not stored in the CGI-bin directory

2.5 Ensure that web forms check data before passing it to the server

3. Ensure protocol security

3.1 Protect fixed internet connection  and internet protocol (IP) address

3.2 Protect shared network  resources from intrusion according to business requirements

3.3 Ensure that personal computer (PC) protocols and preferences follow security protocols 

3.4 Disable control protocol or internet protocol (TCP/IP) bindings for file and printer sharing

3.5 Ensure that network basic input/output system (NetBIOS) over TCP/IP is disabled

Evidence Guide

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:

  • identify password protection solutions
  • install and maintain intrusion detection system
  • manage protocol security.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • a basic website
  • web servers
  • appropriate learning and assessment support when required.

Where applicable, physical resources should include equipment modified 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 candidate installing and testing website security system
  • verbal or written questioning to determine candidate’s knowledge of:
  • client business requirements
  • industry website security standards
  • appropriate software and hardware to implement security on a website
  • evaluation of candidate’s website security documentation.

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.
