- Monitor vulnerability, audit, and continuous monitoring data to maintain awareness of system security posture.
- Coordinate with engineering, operations, and program teams to support implementation of security controls and corrective actions.
- Participate in security assessments, audits, and inspections, including interactions with assessors and customer stakeholders.
- Review security documentation, control evidence, and implementation artifacts for accuracy and completeness.
- Evaluate products, services, and proposed technical solutions for compliance, risk, and implementation considerations.
- Support customer integration of managed services by assisting with control implementation, inheritance analysis, and security documentation activities.
- Contribute RMF and compliance expertise to solution implementation, delivery efforts, and operational improvement initiatives.
- Maintain awareness of evolving federal compliance requirements, security threats, and industry best practices.
