Conduct and review security assessments, maintain system patches, risk analysis, and vulnerability scans (Nessus, ACAS, SCAP) to identify and remediate risks.

Evaluate proposed changes to hardware, software, and firmware for security impact; approve or reject changes in accordance with the Configuration Management (CM) process.

Oversee implementation and validation of STIG/SRG hardening requirements across Windows, Linux, and network infrastructure.

Vulnerability Management and Continuous Monitoring:

Run and interpret vulnerability scans (ACAS, SCAP or equivalent tools), triage findings, and drive remediation with the responsible engineering teams.

Maintain the system’s continuous monitoring strategy post- ATO, including tracking control effectiveness overtime and flagging drift.

Support incident response for accredited systems, including root-cause security analysis and reporting.
