Modification History



Release 1

This Unit first released with ICA11 Information and Communications Technology Training Package version 1.0

Unit Descriptor

This unit describes the performance outcomes, skills and knowledge required to implement and manage security functions throughout a network.

Application of the Unit

This unit applies to middle managers, such as information security managers, network engineers or security analysts, responsible for implementing and managing the organisational security management system.

They provide technical advice, guidance and leadership in resolution of specified problems and the role may involve responsibility for others. The role also involves leading development of strategic reviews, determining security threats and implementing controls to mitigate risk. Related tasks include network security planning, implementation, cost-analysis and budgeting.

Licensing/Regulatory Information

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.


Not applicable.

Employability Skills Information

This unit contains employability skills.

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.

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

  • analytical skills to:
  • analyse network information
  • plan approaches to technical problems or management requirements
  • communication skills to:
  • convey and clarify complex information
  • liaise with clients
  • literacy skills to interpret and prepare technical documentation, including recording security incidents and developing security policies
  • planning skills to plan control methods for managing system security
  • problem-solving skills to:
  • apply solutions in complex networks, including systems processes
  • deploy rapid deployment of solutions to problems involving failure and security incidents
  • technical skills to apply best practice to systems security methodologies and technologies.

Required knowledge 

  • detailed knowledge of:
  • auditing and penetration testing techniques
  • logging analysis techniques
  • organisational network infrastructure
  • related weaknesses of installed network infrastructure
  • security technologies
  • broad knowledge of:
  • capabilities of software and hardware solutions
  • emerging security issues
  • general features of emerging security policies, with depth in security procedures
  • network management and security process controls
  • network security implementation risk management plans and procedures.

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 threats to security
  • develop risk management plan
  • design network security policies
  • analyse and plan solutions to compromised networks and design incident response
  • evaluate security information and use it to plan suitable control methods and countermeasures
  • add network controls, according to system security policies, procedures and risk management plan.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • site or prototype where network security may be implemented and managed
  • network support tools currently used in industry
  • organisational security policies, manufacturer recommendations and security standards
  • 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:

  • verbal or written questioning to assess candidate’s knowledge of emerging security issues, security features of hardware and software, limitations in vendor solutions, operating systems and software
  • direct observation of candidate demonstrating management of network security in a range of complex security situations
  • review of documentation prepared by candidate to manage network security.

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.
