• Analyze scan results, validate findings, triage false positives, and track remediation in support of Plans of Action and Milestones (POA&Ms).
• Administer Trellix ePO within the enterprise enclave, including agent deployment, policy enforcement, update scheduling, and verification of signature/definition compliance.
• Produce endpoint compliance metrics and operational reports for leadership, system administrators, and inspection teams.

3. Enclave Boundary Defense & Security Administration

• Monitor and maintain the security posture of enclave gateways, firewalls, boundary devices, and intrusion detection/prevention systems (IDS/IPS).
• Help protect enclave resources against unauthorized access, modification, destruction, or disclosure.
• Review change requests and conduct Security Impact Analyses (SIA) for system modifications, port/protocol changes, and routing updates.
• Coordinate with systems and network administrators to ensure security and monitoring requirements are integrated into system deployments and changes.

4. Risk Management Framework (RMF) & eMASS Administration

• Support end‑to‑end RMF activities in eMASS, including maintaining System Security Plans (SSPs), continuous monitoring strategies, and security control implementation statements.
• Populate, update, and manage system milestones, control assessments, test results, and POA&Ms within eMASS.
• Verify implementation and enforcement of DISA Security Technical Implementation Guides (STIGs) and Security Requirements Guides (SRGs) across assigned systems.
