Risk Management Framework (RMF) Compliance:

• Lead the implementation of RMF processes to ensure secure system development, deployment, and operation.
• Create and maintain documentation for Authorization to Operate (ATO) submissions, including System Security Plans (SSPs) and security assessment reports.
• Coordinate with Authorizing Officials and other DoD stakeholders to obtain and sustain the system's ATO.

Cybersecurity Testing and Validation:

• Plan, execute, and oversee vulnerability scans, penetration testing, and security assessments for space-based systems.
• Analyze test results and prepare recommendations for system hardening and risk reduction.
• Collaborate with engineering teams to resolve identified security gaps and enhance system resilience.

Incident Response and Monitoring:

• Develop and implement procedures for detecting, reporting, and responding to potential security incidents.
• Assist operations teams with real-time cybersecurity monitoring to identify and mitigate threats.

Collaboration and Stakeholder Engagement:

• Work closely with program managers, system architects, engineering teams, and external contractors to ensure cybersecurity requirements are met.
• Act as the cybersecurity expert and advisor during design, testing, deployment, and operational phases of the systems.

Documentation and Reporting:

• Prepare cybersecurity documentation, including risk analysis reports, mitigation plans, technical white papers, and system certifications.
• Present findings and progress reports to DoD stakeholders and leadership.
