• Direct technical containment, eradication, and recovery activities (e.g., isolate or revoke credentials), in coordination with the DEOS incident manager and DISA stakeholders.
• Capture lessons learned and drive assist in updates to runbooks, playbooks, detection rules, and hardening baselines to reduce recurrence.

Consultative Customer and Stakeholder Engagement

• Engage with GDIT, DEOS and DISA security, engineering, and operations counterparts to clarify requirements, constraints, and risk posture for DEOS services.
• Provide consultancy‑style briefings and technical input to change boards, engineering reviews, and security forums on proposed changes, risks, and mitigations.
• Support responses to DISA/DoW data calls, audits, inspections, and technical reviews related to DEOS cybersecurity and system integrity.

Documentation, Governance, and Continuous Improvement

• Develop and maintain technical documentation for DEOS Azure components, including architecture diagrams, configuration baselines, runbook catalogs, incident response playbooks, and RMF artifacts.
• Ensure activities align with GDIT Security Standard Practices, DEOS‑specific governance processes, and applicable ISO 27001 / information security management expectations.
• Identify opportunities to improve automation, monitoring, and repeatable processes that enhance DEOS security, reliability, and operational efficiency.
