Manage network security


Application

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

It applies to individuals with excellent information and communications technology (ICT) expertise who lead the development of strategic reviews of security and provide technical advice, guidance and leadership in resolution of specified problems.

No licensing, legislative or certification requirements apply to this unit at the time of publication.


Elements and Performance Criteria

ELEMENT

PERFORMANCE CRITERIA

4.2 Design security measures for network components

4.3 Obtain feedback and adjust if required

4.4 Develop security policies

5. Design and implement responses to security incidents

5.1 Design auditing and incident response procedure

5.2 Document security incidents

5.3 Implement configurations aligned with incident response procedure design

5.4 Test and sign off

Evidence of Performance

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.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.


Evidence of Knowledge

To complete the unit requirements safely and effectively, the individual must:

recognise and describe common ICT networks and their configuration

identify and describe network attacks, vulnerabilities and related weaknesses of installed infrastructure, including:

security technologies

emerging security issues

identify and describe network security measures, including:

auditing and penetration testing techniques

logging analysis techniques

organisational network infrastructure

capabilities of software and hardware solutions

general features of emerging security policies, with depth in security procedures

network management and security process controls

explain network security implementation risk management plans and procedures, including:

network security planning

implementation

cost analysis and budgeting.


Assessment Conditions

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the network industry, and include access to:

a 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.

Assessors must satisfy NVR/AQTF assessor requirements.


Foundation Skills

This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
