System Security Plan Content, v1.0

Defines conformance and assessment criteria for compliance with minimum security requirements for system security plan content as related to overall security planning requirements.
If an assessment step references organization-defined elements (E.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), corresponding citations/excerpts must be provided to confirm that the organization has established and documented these values and that they apply as referenced in the conformance criteria.

Similarly, if a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]) is specified, evidence must be provided to establish that the option(s) implemented by the organization have been defined and documented.

The assessment step shall not be marked as satisfied without this evidence.

Has the organization developed a security plan for the information system that: Is consistent with the organization's enterprise architecture; Explicitly defines the authorization boundary for the system; Describes the operational context of the information system in terms of missions and business processes; Provides the security categorization of the information system including supporting rationale; Describes the operational environment for the information system and relationships with or connections to other information systems; Provides an overview of the security requirements for the system; Identifies any relevant overlays, if applicable; and Describes the security controls in place or planned for meeting those requirements including a rationale for the tailoring decisions?

Provide evidence (e.g. organizational policies, procedures, compliance/assessment reports, etc.) that support the assessor's response to this assessment step.
If conformance criteria reference organization-defined elements (e.g. <organization-defined personnel or roles>, <organization-defined frequency>, etc.), these values must be defined and documented by the organization.

Similarly, if the criteria specify a "Selection" among multiple options (e.g. [Selection (one or more): as needed; ]), the option(s) implemented by the organization must also be defined and documented.
