Job Analysis:

The ACAS Cyber Systems Administrator role at Langley AFB is fundamentally centered on maintaining and optimizing vulnerability management systems within a high-security DoD environment. This position requires a blend of technical acumen, operational discipline, and cybersecurity compliance expertise to ensure the ongoing protection and risk reduction of critical government IT infrastructure. The successful candidate will regularly manage ACAS (Assured Compliance Assessment Solution) tools—particularly configuring and running vulnerability scans, analyzing results, and enforcing compliance with strict DoD cybersecurity mandates such as STIGs and RMF documentation. Beyond routine system administration, the role demands proactive problem-solving to troubleshoot scan failures, integrate new systems, and automate repetitive tasks via scripting, reflecting an emphasis on efficiency and precision. The Mid-level role expects foundational knowledge in cybersecurity (e.g., Security+ certification) and DoD secret clearance, indicating the need for reliability and trustworthiness in handling sensitive information. The Senior role raises the bar to top-secret clearance with greater responsibility in network design, risk scoring, and managing complex cybersecurity environments, implying a strategic oversight component. Throughout, strong communication skills are critical to collaborate cross-functionally with system and security teams and to document security posture and remediation plans clearly. Success in this role equates to achieving near-perfect scan coverage, timely vulnerability mitigation, and seamless compliance reporting—thus enabling the broader organization’s mission assurance and cyber resilience.
