Application
This unit describes the skills and knowledge required to use software tools, equipment and protocols to configure network devices in the design of the infrastructure of a secure network.
It applies to individuals with advanced information and communications technology (ICT) skills who adapt router and switch operating system capabilities to mitigate attacks.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Implement layer 2 security | 1.1 Configure using router operating system (OS) commands to mitigate layer 2 attacks 1.2 Implement identity-based networking services (IBNS) on switches to provide layer 2 security 1.3 Implement identity management using access control system (ACS) as the authentication server |
2. Configure router OS intrusion prevention system (OS-IPS) to mitigate threats to network resources | 2.1 Evaluate the advanced capabilities of router OS-IPS firewall feature set to include event action processing (EAP) for threats to network resources 2.2 Configure and verify IPS features to identify threats and dynamically block them from entering the network 2.3 Maintain, update and tune the IPS signatures 2.4 Configure and verify context-based access control (CBAC) and network address translation (NAT) to dynamically mitigate identified threats to the network 2.5 Configure and verify zone-based firewall (ZFW) to include advanced application inspections and uniform resource locator (URL) filtering for improved network security |
3. Configure virtual private networks (VPNs) to provide secure connectivity for site-to-site and remote access communications | 3.1 Analyse and evaluate internet protocol security (IPSec) and generic routing encapsulation (IPSec/GRE) features and functionality 3.2 Configure secure connectivity for site-to-site VPN using certificate authorities 3.3 Analyse dynamic multipoint VPN (DMVPN) features and capabilities 3.4 Configure and verify secure connectivity for site-to-site VPN operations 3.5 Provide highly secure network access with secure socket layer (SSL) VPN to deliver remote access connectivity features and benefits 3.6 Evaluate EasyVPN benefits and configure EasyVPN server with dynamic virtual tunnel interface (DVTI) to create a virtual access interface on the virtual tunnel interface 3.7 Configure and verify EasyVPN remote to establish a site-to-site connection using both router and VPN software clients 3.8 Implement group-encrypted transport (GET) VPN features to simplify the provisioning and management of VPN |
4. Implement network foundation protection (NFP) | 4.1 Evaluate NFP features and functionality to provide infrastructure protection 4.2 Secure the management plane, the data plane and the control plane using OS features of the router |
Evidence of Performance
Evidence of the ability to:
evaluate network security system requirements
design, implement and verify network security systems using layer 2 and layer 3 devices
mitigate threats to network security
configure virtual private networks (VPNs) for secure connectivity
evaluate and implement network foundation protection (NFP).
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:
explain configuration, verification and troubleshooting procedures to undertake:
virtual local area network (VLAN) switching
inter-switching communications
outline the key features of deployment schemes
summarise setting up and securing firewalls
explain iDevice operating system (iOS) and internet protocol (IP) networking models
outline local area network (LAN) and wide area network (WAN) implementations
explain network address translation (NAT) concepts and configuration
outline network topologies, architectures and elements
explain networking standards and protocols
outline procedures for configuring, verifying and troubleshooting router operations and routing
summarise secure connectivity and remote access communications
explain security protocols, such as secure socket layer (SSL)
clarify threat mitigation strategies
outline tunnelling protocols
summarise VPN technologies.
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 networking industry, and include access to:
a site or prototype where network security may be evaluated and tightened
hardware and software
organisational guidelines, procedures and policies
computers
hardware and software LAN and WLAN internetwork technologies
hardware and software security technologies.
Assessors must satisfy NVR/AQTF assessor requirements
