How to Develop a System Security Plan for NIST SP 800-171 Compliance

May 13, 2025

If your organization handles Controlled Unclassified Information (CUI) on behalf of the Department of Defense (DoD), a System Security Plan (SSP) isn’t optional—it’s a requirement.

Our on-demand webinar, Developing a Strong System Security Plan, offers essential guidance for understanding, building, and maintaining an SSP that aligns with the DFARS 252.204-7020 clause and the NIST SP 800-171 framework. This is a must-watch session for any contractor seeking to stay eligible for DoD work and demonstrate cybersecurity due diligence.

What You’ll Learn

  • What is a System Security Plan (SSP): Get a clear overview of what an SSP is, its purpose, and how it plays a central role in meeting federal cybersecurity requirements.
  • Why is an SSP critical for DoD contractors: Understand how an SSP helps you comply with NIST SP 800-171 and DFARS 252.204-7020—and what could happen if you don’t have one in place.
  • What should your SSP include: We outline the key elements: system boundaries, CUI environments, security controls, user roles, and risk mitigation strategies.
  • How do you start building your SSP: Learn the step-by-step process—from identifying relevant stakeholders and systems, to conducting a gap analysis and implementing technical and administrative controls.
