Elements and Performance Criteria

1. Define a process for designing security
   • Define planning phase for network security design
   • Define building phase for network security design
   • Define managing phase for network security design
2. Identify threats to network security
   • Determine why attacks occur
   • Determine who the attack may come from
   • Analyse common types of network vulnerabilities
   • Determine how attacks occur
   • Design a threat model to categorise treats
3. Analyse security risks
   • Determine elements of risk management
   • Determine assets that require protection
   • Categorise assets and calculate their value to the organisation
   • Create a risk management plan
4. Create a security design
   • Determine attacker scenarios and threats
   • Design security measures for network components
   • Obtain feedback and adjust if required
   • Develop security policies
5. Design and implement responses to security incidents
   • Design auditing and incident response procedure
   • Document security incidents
   • Implement configurations aligned with incident response procedure design
   • Test and sign off

Performance Evidence

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.
