ICAI5250A
Develop, implement and evaluate system and application security

This unit defines the competency required to develop, implement and evaluate information security in an IT system or application during the System Development Life Cycle (SDLC) prior to the Operations and Maintenance phase. The practice of these protocols ensures that the operation of IT systems and software does not present undue risk to the enterprise and its information assets. This objective is accomplished through risk assessment; risk mitigation; security control selection, implementation and evaluation; and software security standards compliance.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the following is essential:

IT system or application security plan

Application and verifying compliance with the identified standards

Practise secure coding practices

Assess and evaluate system compliance

Context of and specific resources for assessment

Assessment must ensure:

Author an IT system or application security plan

Apply and verify compliance with the identified standards

Ensure the integration of information security practices

Re-engineer security controls to mitigate vulnerabilities

Assess and evaluate system compliance

To demonstrate competency in this unit the following resources will be needed:

IT business specifications

Information on the security environment including relevant laws/legislation, existing organisational security policies, organisational expertise and knowledge

Possible security environment also includes the threats to security that are, or are held to be, present in the environment

Risk analysis tools/methodologies

IT security assurance specifications

Application and system scenarios

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.

The following assessment method is appropriate for this unit:

Competency in this unit should to 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.

Additionally, an individual demonstrating this competency would be able to:

Demonstrate understanding of specialised knowledge with depth in some areas

Analyse, diagnose, design and execute judgement across a broad range of technical or management functions

Generate ideas through the analysis of information and concepts at an abstract level

Demonstrate a command of wide-ranging, highly specialised technical, creative or conceptual skills

Demonstrate accountability for personal outputs within broad parameters

Demonstrate accountability for personal and group outcomes within broad parameters.
