• Coordinate changes to classified system components, environments, and physical locations, including temporary relocations.
• Assist the ISSM in reporting, documenting, and mitigating information system security incidents; initiate corrective measures to prevent recurrence.
• Support secure media handling, sanitization, COMSEC activities, and classified data management.
• Partner with engineering teams throughout system design, development, integration, testing, deployment, and sustainment to ensure security is incorporated into every phase.
• Provide cybersecurity guidance and technical expertise to cross‑functional teams.
