Why it matters
Cloud is how modern government runs, and FedRAMP is the gate every cloud service must pass to sell to a US federal agency. That makes it one of the highest-leverage things a GRC professional can actually understand: a single FedRAMP authorization can unlock hundreds of agency customers under 'authorize once, reuse many', which is why it is worth a heavy, expensive, months-long process that vendors nonetheless line up for. The people who can shepherd a cloud service through it — read a FIPS 199 categorization, argue an inheritance boundary, manage a 3PAO, keep a POA&M honest and stand up…
What you'll learn
- explaining what FedRAMP is and why it exists, from zero
- choosing between an Agency ATO and a FedRAMP Board P-ATO path
- deriving a FedRAMP impact level (Low/Moderate/High) from FIPS 199 categorization
- mapping impact levels to NIST SP 800-53 Rev 5 control baselines via the FedRAMP baselines
- understanding the role of a 3PAO and the independence rule
- assembling the core package: SSP, SAP, SAR, POA&M and continuous monitoring
- building a control-responsibility / inheritance matrix
- outlining a Moderate SSP and starting a POA&M
- judging WHEN a vendor should pursue FedRAMP and when it is the wrong call
- reading the modernized program: the FedRAMP Board, FedRAMP 20x and OSCAL
Steps in this lab
- What FedRAMP is, and the problem it was built to kill
- Do the NIST RMF once, so you can reuse it everywhere
- Categorize the data with FIPS 199 — where the impact level is born
- Map the level to a control baseline — FedRAMP's tailoring of SP 800-53 Rev 5
- Deliverable 1 — build the control-responsibility / inheritance matrix
- The 3PAO — why a cloud provider is not allowed to grade its own homework
- The required package — SSP, SAP, SAR, POA&M, and ConMon
- The two paths — Agency ATO vs FedRAMP Board P-ATO — and what changed in 2024-2025
- The Marketplace and 'authorize once, reuse many'
- Deliverables 2 and 3 — the SSP skeleton and the starter POA&M
- When to pursue FedRAMP, when NOT to, and how a pro does it better
