• Own and maintain the System Security Plan (SSP) and Plan of Action & Milestones (POA&M) for all CUI-scoped systems; always keep documentation audit-ready. - Assess all 110 NIST SP 800-171 practices for implementation and effectiveness; map existing controls (Wazuh, ThreatDown, Tenable, ManageEngine, AD GPOs, SnipeIT) to CMMC requirements, identify gaps, and drive remediation. - Maintain the organizational risk register; support ongoing Risk Management Framework (RMF) processes and report risk posture to the CISO. - Lead preparation for CMMC Level 2 assessments — build evidence packages, coordinate with the C3PAO, and manage assessor requests and findings. - Develop and maintain cybersecurity policies, procedures, and standards aligned to CMMC, DFARS, SOC 2, and GDPR; ensure version control and staff acknowledgment records are maintained. - Define, track, and report security metrics and KPIs to the CISO and non-technical stakeholders including legal, contracts, and business development teams. - Support contract teams with DFARS clause requirements, cybersecurity representations, and customer security questionnaires. - Conduct vendor and third-party risk assessments; maintain supplier risk documentation. - Manage the security awareness training program and phishing simulations; maintain completion records per CMMC requirements. Security Operations (secondary)

• Monitor SIEM for security events and alerts relevant to CUI systems; write and tune detection rules; triage and escalate incidents; produce post-incident reports with compliance impact assessment. Leverage audit log aggregation to satisfy CMMC AU (Audit & Accountability) control evidence requirements. - Monitor EDR alerts for CUI-scoped endpoints; investigate detections and coordinate response with IT. - Work with IT to ensure vulnerability findings are remediated within CMMC-required timeframes, track and report on remediation status. - Leverage MDM and Active Directory to enforce device compliance, GPO-based security baselines, and access control policies across CUI-scoped endpoints. - Use asset inventory as the authoritative hardware/software asset register for CMMC system boundary documentation; keep it current and audit ready. - Conduct periodic access control audits; enforce least-privilege across AD, SSO, and SaaS tooling handling CUI.
