Authority to Operate, Built on NIST 800-53 Inheritance
FISMA compels every federal agency and contractor handling federal information to implement, document, assess, and continuously monitor NIST 800-53 controls. Our FedRAMP High infrastructure pre-implements 300+ of those controls so your authorization package starts on second base.

What FISMA / NIST 800-53 Means for Your Organization
The Federal Information Security Modernization Act of 2014 — and the original 2002 act it amended — requires every federal agency and contractor handling federal information to implement an information security program built on NIST standards. NIST 800-53 Rev 5 is the technical control catalog that gives FISMA its teeth.
Universal Federal Mandate
FISMA applies government-wide. Every federal agency, every system handling federal information, and every contractor operating one of those systems falls within scope under OMB Circular A-130.
NIST 800-53 Rev 5
The current revision adds privacy controls, supply chain risk management (SR family), and consolidated control language. New systems must meet Rev 5; legacy systems are migrating per OMB guidance.
Three-Year Authorization Lifecycle
Most ATOs are valid for three years, with annual reauthorization checkpoints. Significant system changes trigger reassessment. Continuous monitoring fills the gaps.
Reciprocity Across Agencies
OMB encourages reuse: a system authorized at one agency can be accepted at another via package review rather than reassessment, when impact levels and overlays align.
The 7-Step Path to a FISMA Authorization
FISMA implementation runs through the NIST Risk Management Framework — a structured, repeatable process every federal information system must complete to achieve and maintain Authority to Operate. Each step generates artifacts that feed the next.
20 Control Families · 1,000+ Individual Controls
NIST 800-53 Revision 5 organizes the federal security and privacy control catalog into 20 families. The catalog is the technical backbone of every FISMA authorization, FedRAMP package, and DoD RMF accreditation.

Control Inheritance for FISMA
Cut Documentation by 70% with Pre-Assessed Controls
Because GovDataHosting’s infrastructure has already been assessed by an accredited 3PAO at the FedRAMP High baseline, your FISMA authorization package can mark our infrastructure controls as fully or partially inherited — focusing your team’s effort on application-layer responsibility only.
Your Path to FISMA / NIST 800-53 Compliance
Our proven methodology shortens timelines and reduces risk by combining inheritable controls, dedicated compliance staff, and direct experience with FISMA-aligned authorizations.
Categorize & Boundary
Apply FIPS 199 to assign impact level. Define authorization boundary including all in-scope components and data flows.
Inherit & Tailor
Map your system to GovDataHosting’s pre-assessed controls. Tailor remaining controls to your application context.
Implement & Document
Deploy on FedRAMP High infrastructure. Build the SSP using inheritance matrices that show exactly what’s already done.
Authorize & Monitor
Coordinate independent assessment, support AO decision, and operate under continuous monitoring with monthly reporting.
FISMA Solutions by Audience
FISMA applies to every federal agency and to contractors operating systems that store, process, or transmit federal information.
Civilian Federal Agencies
HHS, DHS, Treasury, VA, GSA, Education and other civilian agencies subject to FISMA implementation under OMB oversight.
Prime Contractors
Federal prime contractors operating systems that handle federal information must satisfy FISMA-equivalent security through contract clauses.
Education & Nonprofit
Universities and research institutions handling federally funded data, grants, or controlled research are subject to FISMA-aligned requirements.
FISMA / NIST 800-53 FAQs
Is FISMA only for federal agencies, or does it apply to contractors too?
FISMA flows to contractors through contract clauses such as FAR 52.239-1 and agency-specific provisions. If your system stores, processes, or transmits federal information — even on your own infrastructure — you are operationally subject to FISMA-equivalent security requirements regardless of whether the word ‘FISMA’ appears verbatim in your contract.
What is the difference between Low, Moderate, and High impact systems?
FIPS 199 categorization assesses potential harm if confidentiality, integrity, or availability is compromised. Low equates to limited adverse effect, Moderate to serious adverse effect, and High to severe or catastrophic effect. The categorization determines which NIST 800-53 baseline applies and drives the rigor of the assessment, controls, and ongoing monitoring.
How long does a FISMA authorization typically take?
A traditional FISMA Moderate ATO from kickoff to authorization commonly runs 9–12 months for a new system. Our customers typically reach authorization 30–40% faster because 300+ infrastructure-layer controls are already implemented and 3PAO-assessed at the FedRAMP High baseline — eliminating the most time-consuming portion of the documentation and assessment effort.
Do we still need a System Security Plan if we inherit controls?
Yes. Every system requires its own SSP. However, when inheriting from a FedRAMP-authorized provider, large portions of your SSP simply reference the provider’s control implementation by inheritance. Your team focuses the SSP on the application-layer narrative — typically 30% of the documentation effort of a from-scratch implementation.
