Evidence Required

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

create secure applications

plan security strategies

ensure safe communications

prevent security attacks

Context of and specific resources for assessment

Assessment must ensure access to

security configuration tools

software development environment

testing and debugging tools

network resources

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

verbal or written questioning to assess candidates knowledge of

application security concepts

cryptographic algorithms

application protection against injections

evaluation of candidates ability to

create secure code and perform security configurations

apply secure communications

protect data and code

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 nonEnglish speaking background may need additional support

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge

Range Statement

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.

Application security may include:	code protection cryptography injections security access control (SAC): authentication authorisation.
Security configuration tools may include:	Java Policy Tool (policytool.exe) for setting code and principal-based security policies .NET security configuration files: enterprise machine user .NET security configuration tools: Caspol.exe Mscorcfg.msc.
Code access permission may include:	file system rights and authorisation java.security.Permission or java.security.BasicPermission NET Code Access Permission class.
Authentication and authorisation strategy may include:	certificate management login mechanism membership provider role-based security user access control (UAC) web service rights and authentication.
Cryptographic algorithms may include:	asymmetric hashes password-based encryption signatures symmetric.
Secure input and output handling may include:	escaping input encoding input validation output encoding parameterised structured query language (SQL) queries.
