Use the tested operating system, platform, processor, hypervisor, and security policy restrictions as claim boundaries, not as optional implementation details. Under FIPS 140-3, operational environment is part of the cryptographic module security case. For software, firmware, and hybrid modules, CMVP guidance treats the environment as the module components, computing platform, and operating system that allow the module to execute; for software modules, listed environments also need the operating system, platform, processor, and any hypervisor used during testing. ## What does operational environment mean in FIPS 140-3? FIPS 140-3 names operating environment as one of the security requirement areas for cryptographic modules. That matters because the validated security level is chosen for the application, environment, and services where the module will be used. The CMVP implementation guidance defines operational environment for software, firmware, and hybrid modules as the management of the software, firmware, and hardware needed for the module to operate. At minimum, that includes the module components, the computing platform, and the operating system that controls or allows the software or firmware to execute. - Treat operational environment as part of the module claim boundary, not as a deployment note that can be changed freely. - For software, firmware, and hybrid modules, identify the module components, computing platform, and operating system before relying on a FIPS 140-3 claim. - Use the module security policy and certificate evidence to understand restrictions on the environment where the module was tested. Sources for this answer: - [NIST FIPS 140-3 security requirements for cryptographic modules](https://doi.org/10.6028/NIST.FIPS.140-3?ref=sorena.io) - Identifies operating environment as a FIPS 140-3 security requirement area and ties validation level selection to the application and environment where the module is used. - [CMVP Implementation Guidance for FIPS 140-3](https://csrc.nist.gov/csrc/media/Projects/cryptographic-module-validation-program/documents/FIPS%20140-3/FIPS%20140-3%20IG.pdf?ref=sorena.io) - Defines operational environment for software, firmware, and hybrid modules as including module components, computing platform, and operating system. ## How should teams check a tested operational environment? Start with the certificate, security policy, and algorithm validation evidence for the exact module and version. CMVP guidance says cryptographic module validation certificates state the module name, version, and tested operational environment; CAVP algorithm certificates also state the tested operational environment for the algorithm implementation. For software modules, each listed operational environment must include the operating system, platform, and processor used for testing. If a hypervisor was used, it must be listed too. Do not treat a different processor bit size, a different operating system, or a different platform as covered unless the evidence actually lists or includes that environment. - Record the module name, version, certificate evidence, and security policy before mapping it to a product or customer environment. - For software modules, capture operating system, platform, processor, and hypervisor if used. - When embedding a validated algorithm implementation, check that the algorithm's tested operational environment is identical to, or fully included in, the module environment being tested.

The main mistake is stretching a validation claim beyond the environment that was tested. CMVP guidance says a claim cannot be made for a different processor bit size when an implementation was tested on one bit size, and a claim cannot be made for another operating system when the implementation was tested on one operating system for module testing. For Level 1 software in a general-purpose operational environment, the CMVP guidance also points to operating-system capabilities that protect critical and sensitive security parameters: each module instance must control its own SSPs, the environment must separate application processes, and spawned processes must be owned by the module rather than external processes or operators. - Do not rely on a validation for a different operating system, processor bit size, platform, or hypervisor unless the evidence supports that environment. - Do not substitute administrative procedures for operating-system capabilities that the CMVP guidance says must be enforced by the module or environment. - Do not present a product as FIPS 140-3 validated merely because it uses a validated algorithm; the module, version, configuration, and tested operational environment still have to match the claim.
