Partner with ISSM/ISSOs, FSO/CPSO, and Authorizing Official/SCA stakeholders to coordinate accreditation activities and packages (SSP, POA&M, Contingency Plan, Incident Response Plan), continuous monitoring, and renewal timelines; oversee eMASS entries where applicable. Partner with ISSM/ISSOs, FSO/CPSO, and Authorizing Official/SCA stakeholders to ensure compliance with RMF/NIST guidance, DCSA/NISPOM (32 CFR Part 117), JSIG/ICD requirements, and contract‑specific directives. Define and manage the classified infrastructure budget, including forecasting for hardware, software, licensing, and lifecycle refresh; lead capacity planning for compute, storage, and network. Oversee procurement, deployment, and sustainment of classified lab equipment, tools, and systems; ensure supply chain risk management and asset accountability. Implement STIG‑aligned baselines and enforce change management for all classified systems. Integrate security operations with IT operations: vulnerability scanning, remediation SLAs, SIEM logging, audit trail retention, and compliance reporting. Lead strategic planning for modernization (virtualization, hybrid/edge compute, automation, infrastructure‑as‑code where permitted) to increase agility and resilience of classified environments. Develop and track KPIs/KRIs for operational health, accreditation posture, incident response, and audit readiness; conduct regular internal reviews and readiness assessments. Serve as primary point of contact to the CIO and senior leadership for classified infrastructure status, risks, and investments; provide clear updates and recommendations. Coordinate cross‑domain requirements and guard solutions with appropriate security teams and authorizing officials where applicable. Ensure proper physical controls for classified labs and systems in coordination with Facilities and Security (access control, TEMPEST considerations, media handling, and destruction procedures).
