CSfC Information Systems Security Technical Auditor

The Commercial Solutions for Classified (CSfC) Information Systems Security Specialist is responsible for the assessment, review, and lifecycle security oversight of multi-vendor CSfC architectures in accordance with NSA policies and Capability Packages (CPs).

This position is assessment-focused and does not perform day-to-day system engineering or operational administration. The role evaluates the implementation and effectiveness of security controls and supporting evidence to support risk-based authorization decisions.

The security specialist works closely with system architects, program managers, ISSOs, ISSEs, and accreditation authorities to ensure solutions meet technical, operational, and security requirements throughout the system lifecycle. A strong technical background is recommended to effectively perform security assessment responsibilities.

• Conduct technical security assessments as part of the RMF lifecycle, with emphasis on control implementation and effectiveness.
• Review CSfC solution architectures, enclave boundaries, and data flows to support assessment activities and risk determinations.
• Identify, prioritize, and track vulnerability scan findings from an assessment and reporting perspective.
• Review Security Technical Implementation Guides (STIGs) for compliance and assessment purposes.
• Review Security Information and Event Management (SIEM) solutions to validate appropriate logging, alerting, and monitoring capabilities.

• Develop, review, and maintain security documentation including:
  • eMASS authorization packages
  • NSA CSfC Registration packages
  • Cross-Domain Solution (CDS) Assessment & Authorization (A&A) packages
• Document and track Plans of Actions and Milestones (POA&M) findings.

• Assess system compliance with applicable policies and frameworks, including:
  • CSfC Capability Packages (Mobile Access and Multi-Site Connectivity)
  • NIST SP 800-53 Rev. 5 security controls
  • Air Force and USAFE-specific cybersecurity policies
• Conduct security reviews for proposed product substitutions, upgrades, or configuration changes to assess security impact and risk.

• Provide technical assessment guidance to engineers, Authorizing Officials (or their designated representatives), and other stakeholders.
• Interface with NSA CSfC, CDS-E, and AO personnel as required to support assessment and authorization activities.

• Bachelor’s degree in Cybersecurity, Computer Science, Information Systems, or related field, or equivalent experience.
• 5–10+ years of experience in cybersecurity engineering, security assessment, or related roles.
• Demonstrated experience assessing technical security controls in complex system environments.
• Strong understanding of:
  • Encryption technologies including IPsec, VPNs, and certificates
  • Network engineering fundamentals (routing, switching, VLANs)
  • RMF lifecycle, NSA CSfC architecture, and CDS concepts
• Familiarity with CSfC-approved components such as firewalls, VPN gateways, and cross-domain solutions.
• Experience supporting NIST RMF and NIST SP 800-53 Rev. 5 implementations.
• Experience developing or supporting A&A documentation and/or NSA CSfC registration packages.
• Must meet applicable DoD 8140 requirements for cybersecurity roles.

• Experience aligned with IAM Level II or IAT Level II roles.
• DoD 8570/8140 baseline certification (e.g., CISSP, CASP+, CCSP), or ability to obtain within a defined timeframe.
• Prior experience supporting or assessing NSA-approved CSfC solutions.
• Working understanding of technologies such as:
  • Cisco routing, switching, and firewalls
  • Palo Alto firewalls
  • Juniper routing
  • Aruba networking
  • SIEM solutions (PacStar IQ Core preferred)
  • Certificate Authority (CA) solutions
  • Virtual Desktop Infrastructure (VDI) architectures
  • Tenable Nessus (ACAS)
