Implement secure encryption technologies

This unit describes the performance outcomes, skills and knowledge required to ensure secure encryption is selected, implemented and monitored in an information and communications technology (ICT) network, either locally or both.

Application

This unit applies to information technology (IT) professionals who may select, implement and monitor a secure encryption environment in any size enterprise. The encryption system may include local file encryption and encryption across computer networks.


Prerequisites

Not applicable.


Elements and Performance Criteria

1. Determine encryption methods

1.1 Analyse enterprise data security requirements

1.2 Create a new or review an existing security plan to determine appropriate encryption methods

1.3 Review a range of encryption technologies and rank the most appropriate options

1.4 Assess the costs associated with each encryption option

1.5 Document encryption options and costs and forward to appropriate person for decision

2. Implement encryption

2.1 Apply encryption technologies to the enterprise system

2.2 Analyse effect of encryption technologies on user roles and responsibilities

2.3 Inform user of new encryption technologies and effect it has on their responsibilities

3. Monitor encryption

3.1 Analyse implementation of the encryption technologies, confirming function and performance

3.2 Review help-desk records for problems concerning implementation and take appropriate action

3.3 Review system logs for encryption issues and compromises

3.4 Document encryption issues and compromises, notifying appropriate person

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:

analyse enterprise data security requirements

create new or review existing security plan to determine the appropriate encryption methods

rank and document appropriate encryption methods

implement encryption systems informing users of any affects

monitor and document encryption issues and compromises notifying appropriate person.

Context of and specific resources for assessment

Assessment must ensure access to:

site where encryption installation may be conducted

live network

servers

encryption software

encryption tools

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:

review of security analysis and planning report that outlines enterprise security requirements and security plan, including challenges faced and how these were addressed

evaluation of documentation demonstrating review of suitable encryption systems, ranking the most appropriate

verbal or written questioning to assess candidate’s knowledge of encryption types, algorithms, functions and features

direct observation of candidate performing tasks required to successfully implement and monitor a chosen encryption system.

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.
