NIST 800-171 System Security Plan (SSP)

NIST 800-171 System Security Plan for Contractors

When your organization handles Controlled Unclassified Information (CUI) for federal agencies or defense contractors, NIST 800-171 compliance isn't optional—it's a contractual requirement that directly impacts your eligibility for government work. The System Security Plan (SSP) is your primary compliance document, demonstrating how your information systems implement the 110 security controls mandated by NIST Special Publication 800-171.

This NIST 800-171 System Security Plan template helps contractors, subcontractors, and IT service providers document their security posture with the level of detail federal agencies expect. Whether you're pursuing DoD contracts subject to DFARS 252.204-7012, working toward CMMC certification, or responding to requirements from civilian agencies, a well-structured SSP is your foundation.

Who needs this form?

This template is designed for defense contractors, aerospace companies, manufacturing firms, IT service providers, consulting firms, and research organizations that process, store, or transmit CUI on behalf of federal government clients. Compliance officers, IT security managers, CISOs, and GRC professionals will find this template essential for documenting security implementations and preparing for assessments.

What this template covers

The form captures critical details across all NIST 800-171 security requirement families: access control policies, awareness and training programs, audit and accountability mechanisms, configuration management procedures, identification and authentication protocols, incident response plans, maintenance procedures, media protection controls, personnel security measures, physical protection mechanisms, risk assessment processes, security assessment procedures, system and communications protection, and system and information integrity controls.

By completing this SSP template through Paperform, you create a structured, auditable record that can be shared with government contracting officers, third-party assessors, and CMMC auditors. The resulting documentation becomes your central reference for compliance evidence and continuous monitoring.

Streamline compliance workflows with automation

Once you've documented your System Security Plan, use Stepper (stepper.io) to automate downstream compliance workflows. Connect your SSP submissions to periodic control reviews, automatically schedule security awareness training reminders, route documentation updates for approval, and maintain a centralized evidence repository that keeps pace with your evolving security program.

For organizations that need formal sign-off from executives, IT leadership, or contracting officers on specific security controls or Plan of Action and Milestones (POA&M), Papersign (papersign.com) integrates seamlessly to capture binding eSignatures on compliance attestations, ensuring your SSP documentation meets audit requirements.
