SSP Starter Template

## The SSP is the primary document reviewed during a C3PAO assessment. Start with the right structure.Your System Security Plan documents how your organization implements each of the 110 NIST SP 800-171 security practices. C3PAO assessors review it first — it sets the context for everything else in your assessment. Most contractors either don't have one or have one that's a generic template with their name pasted in.This starter template gives you the right structure with specific prompts for every section.---### What's inside:Section 1: System IdentificationName, owner, security officer, authorizing official — all the identification fields an assessor expects to see upfront.Section 2: System DescriptionPurpose, CUI types, user population, and system interconnections — prompted so you know exactly what to document.Section 3: System Boundary & ArchitectureScoping guidance, hardware components, software components, cloud/ESP inventory — with a reminder to attach your network diagram.Section 4: Security Control Implementation (all 17 domains)For each domain: a plain-English prompt describing what to document, with fill-in sections for controls implemented, tools/policies referenced, and evidence file pointers.Section 5: Roles & ResponsibilitiesPre-populated role table (System Owner, SSO, IT Admin, CUI Handler, IR Lead, C3PAO) with assignment fields.Section 6: POA&M ReferenceA summary table linking to your active POA&M document with open item tracking.Section 7: Approval & Signature BlockSystem Owner and SSO signature lines with date fields — required for a complete SSP.---### ImportantThis template provides structure. Your SSP must reflect your actual environment and controls — not aspirational ones. Assessors verify that what you document matches what they observe.
