• Coordinate security evidence and documentation requirements associated with software and infrastructure changes.

• Support software supply-chain security, artifact integrity, provenance, and dependency-management practices.

• Partner with DevSecOps and engineering teams to integrate security controls into development and delivery processes.

• Identify security risks associated with software components and recommend appropriate mitigation or remediation actions.

Continuous Monitoring & Compliance

• Support continuous security monitoring and assessment activities.

• Track security findings, vulnerabilities, control deficiencies, and remediation activities.

• Maintain accurate security documentation, evidence repositories, and compliance records.

• Support audits, assessments, inspections, and other security compliance activities.

• Monitor changes to enterprise systems and evaluate potential impacts to existing security controls and authorization requirements.
