The System Security Plan template is 400 pages, the NIST 800-53 Rev 5 control catalog has 325 controls at the Moderate baseline, and your 3PAO assessment starts in 6 months. Your team has never navigated the FedRAMP process and does not know which AWS GovCloud services map to which NIST controls.\u003c\/p\u003e\n\n\u003cp\u003eThis blueprint is the FedRAMP Moderate architecture I built for a federal health IT contractor that achieved Authority to Operate through the Joint Authorization Board pathway, handling CUI and PII for 2.3M federal employees.\u003c\/p\u003e\n\n\u003ch3\u003eWhat You Get\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eArchitecture diagrams\u003c\/strong\u003e — FedRAMP authorization boundary, data flow diagrams (Level 3), network topology with FIPS 140-2 encryption points, and continuous monitoring architecture (Draw.io)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerraform modules\u003c\/strong\u003e — AWS GovCloud VPC with FIPS endpoints, Config rules mapped to NIST 800-53 controls, CloudTrail with FIPS-validated encryption, KMS with FIPS 140-2 Level 3 HSM backing, and Security Hub with NIST 800-53 standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSSP contribution package\u003c\/strong\u003e — Control implementation statements for all 325 Moderate baseline controls that are infrastructure-related, formatted for direct insertion into FedRAMP SSP templates\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConMon (Continuous Monitoring) automation\u003c\/strong\u003e — Monthly vulnerability scan configuration, POA\u0026amp;M tracking spreadsheet, and automated deviation reporting\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Architecture Decisions\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAWS GovCloud over Commercial AWS with compliance overlays\u003c\/strong\u003e — FedRAMP Moderate requires data residency in the US, FIPS 140-2 validated encryption endpoints, and personnel with US citizenship managing infrastructure. GovCloud provides all three as platform guarantees. Commercial AWS requires you to prove each requirement independently — possible but significantly more audit burden.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFIPS 140-2 endpoints for all service access\u003c\/strong\u003e — Every AWS API call must use FIPS-validated TLS endpoints. The Terraform modules configure provider endpoints to use \u003ccode\u003e*.fips.us-gov-west-1.amazonaws.com\u003c\/code\u003e patterns automatically. A single non-FIPS API call is an audit finding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeparate authorization boundary per application\u003c\/strong\u003e — Combining multiple applications into one FedRAMP boundary seems efficient but means any change to any application requires re-assessment of the entire boundary. Separate boundaries let teams move independently and limit the blast radius of audit findings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfig rules as continuous monitoring evidence\u003c\/strong\u003e — NIST CA-7 requires continuous monitoring.

Deploy the VPC Terraform module and verify that all AWS API calls route through FIPS endpoints by checking CloudTrail logs for \u003ccode\u003e*.fips.\u003c\/code\u003e in the API endpoint field. On day two, deploy the Config rules mapped to NIST 800-53 and run the initial compliance evaluation. The resulting report shows your control implementation status across all 325 Moderate baseline controls — this becomes the foundation for your SSP.\u003c\/p\u003e\n\n\u003ch3\u003eLimitations and Trade-offs\u003c\/h3\u003e\n\u003cp\u003eGovCloud has fewer services than commercial AWS — check the GovCloud service availability page before designing. Some services (Bedrock, newer AI services) are not available in GovCloud. FedRAMP authorization is a 12-18 month process minimum; this blueprint accelerates the technical implementation but does not replace the procedural requirements (3PAO selection, JAB prioritization, agency sponsorship). The SSP contribution package covers infrastructure controls only — application-level controls (AC-7 login attempts, AU-3 audit content) must be documented separately by your application team.\u003c\/p\u003e","brand":"Citadel Cloud Management","offers":[{"title":"Default Title","offer_id":54890408083747,"sku":"CCM-ARC-013","price":89.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/8539\/7027\/files\/citadel-architecture-product_31028237-9847-4834-b195-7bdde09cb4d6.jpg?v=1775138567","url":"https:\/\/citadel-cloud-management.myshopify.com\/products\/government-cloud-fedramp-architecture","provider":"Citadel Cloud Management","version":"1.0","type":"link"}
