Your New Role And Responsibilities
A Midrange Engineer with specific skills in patching multiple operating and application systems contributing to an Essential Eight technical implementation to meet Maturity Level 1 requirements for the Future Compute Environment. This is a specialized IT role focused on supporting and protecting the Dept's infrastructure by thoughtfully reducing its attack surface. The role will collaborate closely with the Lead Security Architect and Infrastructure teams to ensure the systematic application of security patches, updates, and configuration improvements to operating systems (Windows, Linux, Unix) and other Dept‑approved applications. This role is an important contributor to the Australian Cyber Security Centre's (ACSC) Essential Eight, with particular focus on vulnerability mitigation.
Key Responsibilities
* Patch Management Lifecycle: Oversee the evaluation, testing, scheduling, deployment, and validation of security patches and updates for OS and applications, working in partnership with relevant teams to support reliable and effective outcomes.
* System Hardening: Implement security configurations such as removing unnecessary services, closing unused ports, and hardening configurations for browsers, PDF readers, office suites, and other devices with a thoughtful and sustainable approach.
* Vulnerability Remediation: Identify and address security gaps, ensuring critical patches are applied within required timeframes (e.g., 24–48 hours for critical vulnerabilities), while maintaining clear communication and shared understanding with stakeholders.
* Automation and Scripting: Utilize tools like Windows Server Update Services (WSUS), Microsoft Endpoint Configuration Manager, or Linux repository management to enable streamlined and supportive automation.
* Compliance and Reporting: Ensure systems comply with internal security policies and industry regulations (e.g., ISM) through regular, transparent audits and collaborative reporting practices.
* Essential 8 Controls: Support remediation of Essential 8 controls across MFA, Regular Backups, and MS Office Macros.
About You And What You'll Bring
* Technical Knowledge: A deep and practical understanding of Windows, Unix (Group Policy, Active Directory), and Linux systems, paired with a willingness to learn, share knowledge, and collaborate.
* Security Focus: Knowledge of hardening techniques, such as implementing Application Control (e.g., AppLocker, fapolicyd) and Attack Surface Reduction (ASR) rules. This includes hands‑on implementation of Patch Applications and Operating System technical controls aligned with E8 compliance.
* Patch Management: Experience with Microsoft Endpoint Configuration Manager, WSUS, and Ninja 1, with a focus on consistency, reliability, and teamwork.
* Hardening/Security: Familiarity with Microsoft Defender, Configuration Baselines, and File Access Policy Daemon (fapolicyd), applied with a careful and supportive approach to security uplift.
* Frameworks: Understanding of Essential Eight, NIST SP 800‑123, and the ACSC Information Security Manual (ISM).
