Ability to Obtain Public Trust
What You Will Do:

• System Boundary Analysis: Define and maintain system security boundaries across hybrid cloud and on-premises environments, including AWS & Azure CSPs, VMware infrastructure, and legacy datacenter assets.
• Authorization Package Development: Author and maintain System Security Plans (SSPs), Security Assessment Reports (SARs), Plans of Action and Milestones (POA&Ms), and related NIST RMF artifacts for all OCIO-managed systems.
• Continuous Monitoring: Implement and oversee continuous ATO processes aligned with NIST SP 800-137 and OSCAL-based automation, ensuring real-time visibility into system posture.
• Control Inheritance Mapping: Map technical controls across shared service environments, identifying common controls, system-specific controls, and hybrid inheritance relationships as systems migrate to cloud.
• GRC Tool Administration: Manage the ingestion of infrastructure telemetry, vulnerability data, and configuration baselines into GRC platforms to automate compliance evidence collection.
• Network Security Architecture: Evaluate and advise on network segmentation, firewall rules, TIC 3.0 compliance, F5 load balancer configurations, DNS security, and encrypted transit between enclaves and cloud environments.
• Cloud Security Posture: Assess and harden CSP environments including VPC design, Security Groups, IAM policies, CloudTrail/GuardDuty integration, and encryption-at-rest/in-transit configurations.
• Vulnerability Management: Collaborate with the SOC team and infrastructure teams to contextualize vulnerability findings from Tenable and similar tools, prioritizing remediation based on exploitability, exposure, and mission impact-not just CVSS scores.
• Infrastructure Security Reviews: Conduct security assessments of proposed architecture changes, migration plans, and new technology deployments.
• Incident Support: Provide senior-level technical analysis during security incidents, bridging the gap between SOC triage and executive risk communication.
• ISSO Liaison: Work alongside ISSOs to translate technical system changes (network reconfigurations, cloud migrations, new integrations) into risk language and updated authorization documentation.
• SOC Mentorship: Elevate the SOC team's understanding of governance context, helping analysts understand how their detection and response activities map to broader risk management and compliance objectives.
• Technical Translation: Serve as the connective tissue between infrastructure engineers, application teams, ISSOs, and leadership-ensuring security decisions are informed by both technical facts and organizational risk tolerance.
• Vendor Coordination: Engage with contractors and vendors on security requirements, ensuring deliverables meet federal security standards.
