• Drive Essential Eight maturity uplift across Australian environments, with a focus on application control, patching, privileged access restriction, multi‑factor authentication and regular backups.
• Develop and maintain SIEM use cases, detection rules, correlation searches and dashboards to provide actionable visibility across the environment.
• Conduct regular vulnerability assessments, analyse findings, prioritise remediation and track closure through the Plan of Action and Milestones (POAM) register.
• Perform security hardening of Windows Server, Active Directory, virtualisation platforms, storage infrastructure and network devices in accordance with ASD hardening guidance and the ISM.
• Contribute to security architecture assessments, threat modelling and risk assessments for new and existing systems.
• Collaborate with infrastructure engineers to integrate security into system designs, change plans and standard operating procedures.
• Support system accreditation activities, including preparation of security documentation (SSPs, SRMPs, IRPs, DLDs) and evidence gathering for assessments.
• Brief security posture, risks and recommendations to management and government stakeholders.
• Assist with security incident response, investigation and post‑incident review.
