• Develop system risk assessment reports and security assessment documentation based on the cyber threat landscape, threat modelling, vulnerability analysis, and intelligence available through Defence, Government, and industry channels.
• Develop and maintain authorisation artefacts including cyber security risk assessments, security assessment reports, and remediation recommendations to reduce cyber security risk.
• Identify security vulnerabilities, analyse cyber risks, and provide remediation and risk mitigation recommendations to support the secure operation and sustainment of Defence capabilities.
• Provide technical cyber security advice and guidance to Defence stakeholders, engineering teams, and project managers regarding emerging threats, secure architecture, control implementation, and security-by-design principles throughout the system lifecycle.
• Develop and improve techniques, processes, and procedures for the management of cyber security information and associated cyber security activities across Defence environments.

• Provision updates and recommendations relating to platform equipment, utilities, cyber threat models, and security control improvements to support evolving operational and threat environments.
