Federal Data Security
Reference hub on the federal mandates that govern agency and contractor data protection, from FISMA and FedRAMP through DoD zero trust requirements.
13 posts
Federal data security requirements are the statutory, regulatory, and contractual rules governing how United States government agencies and their contractors protect data. FISMA sets the statutory duty for agencies, FedRAMP authorizes cloud services for federal use, and CMMC 2.0 pushes defense requirements into the supply base. Together they define what a control must achieve before data crosses a federal boundary.
Deadlines bind on paper and then get measured at the wrong layer. Agencies report zero trust progress in terms of identity federation, device inventory, and network segmentation, because those are countable. Data-layer enforcement, where policy travels with the object across an authorization boundary, is harder to instrument and correspondingly easy to defer.
Posts under this hub cover the FedRAMP High baseline, DoD Zero Trust Overlays, authority to operate timelines, FIPS 140-3 module validation, federal post-quantum deadlines and post-quantum key encapsulation, and the zero trust data fabric (ZTDF) format that procurement officers keep meeting in requirements language.
Frequently asked questions
What is the difference between FISMA and FedRAMP?
FISMA is the statute requiring federal agencies to run an information security program and to authorize each system, using NIST SP 800-53 Rev 5 controls. FedRAMP applies that model to cloud services: a provider is assessed once against a Low, Moderate, or High baseline, and agencies reuse the authorization package instead of repeating the assessment themselves.
What does CMMC Level 2 require?
CMMC 2.0 Level 2 requires a contractor handling controlled unclassified information to implement the security requirements in NIST SP 800-171, covering access control, media protection, audit and accountability, and cryptographic protection. Assessment runs through a certified third party for prioritized acquisitions and through self-assessment otherwise, with a company official affirming the result.
What are the DoD Zero Trust Overlays?
The DoD Zero Trust Overlays map the department zero trust capabilities and activities onto NIST SP 800-53 Rev 5 controls. They tell a system owner which controls satisfy each target activity across the seven DoD zero trust pillars, and at which level, Target or Advanced. Their function is translating strategy language into concrete control selection.
Does FedRAMP authorization cover data after it leaves the cloud service?
No. A FedRAMP authorization applies to a defined system boundary. Once data is exported, synced to an endpoint, or passed to another service outside that boundary, the authorization says nothing about it. Controls that persist require policy bound to the data object and evaluated at each access request, not at the service perimeter.
