- Develop and maintain authorization documentation, including System Security Plans (SSPs), security control implementation statements, system boundary descriptions, and supporting evidence.
- Coordinate with system owners, Information System Security Managers (ISSMs), assessors, and engineering teams to prepare authorization packages and resolve assessment findings.
- Maintain Plans of Action and Milestones (POA&Ms), track remediation progress, and communicate unresolved risks and dependencies.
- Use the DISA Enterprise Mission Assurance Support Service (eMASS) to maintain authorization records, security control documentation, assessment evidence, and remediation status, as applicable.
- Review Assured Compliance Assessment Solution (ACAS) scan results, security configuration assessments, and application security testing reports; work with technical teams to prioritize and validate remediation.
- Assess the security impact of software releases, infrastructure changes, new integrations, and changes to the authorization boundary.
- Support continuous monitoring by maintaining current security evidence, reviewing control effectiveness, and reporting changes in system risk.
- Work with cloud and DevSecOps engineers to incorporate security requirements and evidence collection into development and deployment workflows.
- Review access controls, privileged access, audit logging, configuration baselines, and protection of sensitive data.
- Support security incident reporting, investigation, corrective actions, and updates to relevant documentation and procedures.
- Apply appropriate security overlays and support supply chain risk management activities.
- Prepare security status reports and brief Government stakeholders on authorization progress, findings, and remediation priorities.
