Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

evaluate network security system threats and requirements

mitigate attacks and configure firewalls

design and implement network security systems

implement VPN using SDM.

Context of and specific resources for assessment

Assessment must ensure access to:

site where network security may be evaluated and tightened

hardware and software

organisational guidelines, procedures and policies

computers

LAN or WLAN internet work technologies (hardware and software)

security technologies (hardware and software)

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:

direct observation of the candidate installing, configuring and testing a new or updated network

evaluation of documentation outlining testing procedures, test results, recommendation to network changes and completion records

verbal or written questioning of required knowledge.

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.


Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assignment, checklist) and due date here

Assessment task 1: [title]      Due date:

(add new lines for each of the assessment tasks)


Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

communication skills to liaise with internal and external personnel on technical, operational and business-related matters

literacy skills to:

interpret technical documentation

write reports as required

numeracy skills to:

take test measurements

interpret results

evaluate performance and interoperability of network

planning and organisational skills to:

coordinate the process in liaison with others

plan, prioritise and monitor own work

problem-solving and contingency-management skills to:

adapt configuration procedures to network requirements

reconfigure depending on differing operational contingencies, risk situations and environments

problem-solving skills to troubleshoot

research skills to investigate appropriate hardware to meet requirements

technical skills to:

select and configure networking devices

assess and implement security requirements.

Required knowledge

router

procedures to set up VPNs

routing protocols

use of command line interface to configure and test network elements.

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.

Network may include:

data

internet

protocol

large and small LANs

virtual LAN (VLAN)

WANs.

Tools may include:

Cisco security device manager (SDM)

command line interface (CLI)

web interface.

Administration access may include:

multiple privilege levels

role-based CLI

strong-encrypted passwords.

Features of TACACS+ and RADIUS AAA protocols may include:

remote authentication dial-in user service (RADIUS):

combines authentication and authorisation

does not allow users to control which commands can be executed on a router

does not support ARA access, NetBIOS Frame Protocol Control Protocol, NASI, and X.25 PAD connections

encrypts only the password in the access-request packet

uses industry standard

uses UDP

TACACS+:

encrypts the entire body of the packet

is Cisco proprietary

offers multiprotocol support

provides two ways to control the authorisation of router commands on a per-user or per-group basis

uses transmission control protocol (TCP)

uses the AAA architecture, which separates authentication, authorisation and accounting.

Access control lists may include:

extended

named

standard.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
