• Risk Management & ATO Support: Identify, assess, and manage security risks, contributing to the program's overall risk posture. Prepare and maintain comprehensive security documentation (e.g., SSPs, SARs, POA&Ms) to support Assessment & Authorization (A&A) processes and achieve/maintain Authority to Operate (ATO).
• Security Control Implementation: Advise and assist development teams in the selection, implementation, and verification of appropriate security controls (technical, operational, and management) for web applications and their supporting infrastructure.
• Policy & Compliance: Interpret and apply relevant government cybersecurity policies, regulations, and guidelines to ensure program compliance.
• Incident Response Support: Provide security expertise and support during security incidents, contributing to containment, eradication, and recovery efforts.
• Continuous Monitoring: Support ongoing continuous monitoring activities to maintain the security posture of deployed applications and systems.
• Collaboration & Communication: Work closely with development teams, system administrators, program managers, and government security stakeholders to foster a strong security culture and ensure effective communication of security requirements and risks.
