• Analyze system changes, configuration updates, and vulnerability data to determine authorization impacts, risk-level changes, and required updates under RMF and JSIG/SAP processes.

• Support ongoing ATO and SAP authorization maintenance by tracking assessments, evidence submissions, and documentation required throughout the RMF and JSIG lifecycles.

• Prepare and deliver clear, risk-focused briefings to system owners, DCSA assessors, SAP authorities, and other stakeholders regarding compliance status, audit results, and security-related decisions.
