Use it to separate validated module scope from product release notes, customer-facing claims, and unsupported certificate reuse. Use this page when a shipped change could alter the cryptographic module that a FIPS 140-3 claim depends on. The useful question is not whether the whole product still sounds compliant; it is whether the validated module name, version, boundary, operational environment, embedded or bound modules, approved services, and certificate evidence still match the changed implementation. ## Start with the validated module, not the product release FIPS 140-3 is a cryptographic module standard. A change-impact review should therefore begin with the module identified in the validation materials: module name, version, type, boundary, operational environment, security level claims, approved services, non-approved services, algorithm certificates, and Security Policy references. A product release, cloud service update, appliance build, or library upgrade can include many changes that never touch the validated cryptographic module. It can also hide one small change that does affect the module boundary or approved-mode claim. Keep those two cases separate before updating customer evidence. - Record the changed product or service version and the FIPS 140-3 module version it depends on. - Compare the changed build against the validated module boundary, including hardware, software, firmware, and hybrid components. - Identify whether the change touches a Security Policy table, module diagram, service definition, role, self-test, algorithm, SSP handling, or operational environment. - Do not reuse a certificate claim if the changed implementation is a different module, version, boundary, or tested environment.

CMVP guidance treats excluded components as still within the module boundary, requires versioning details for them, and says a change to an excluded component changes the overall module version. Bound or embedded validated modules add another impact path. The guidance requires the Security Policy and test report to identify the embedded validated module by name, certificate number, and version, and it warns that a module can inherit Historical status from an embedded validated module. - Flag changes to components inside the cryptographic boundary, including components labelled excluded from requirements. - For bound or embedded modules, check the dependent module certificate number, version, active status, security level relationship, and approved-service use. - For software, firmware, or hybrid modules, compare the changed operating system, platform, processor, and hypervisor against the tested operational environments. - Escalate processor or accelerator changes when the validation relies on PAA, PAI, VAOE, or OEUP assumptions in the Security Policy or test evidence.

CMVP guidance distinguishes complete image replacement from software/firmware loading and ties that distinction to whether load-test requirements apply, whether the replacement is treated as a new module, and whether SSP zeroisation is required before execution of a new image. The change-impact record should therefore capture what changed, how the new code enters the module boundary, whether a software/firmware load test is performed before execution, and whether the Security Policy, versioning, and self-test evidence still match the implementation. - Record whether the update is a complete image replacement, an overlay, an externally loaded component, an operator-initiated software or firmware update, or an FPGA bitstream change. - Check that changed software or firmware components cannot execute until the applicable load or integrity test has completed successfully. - For complete image replacement, capture the new-module treatment, power-on reset behavior, SSP zeroisation evidence, and versioning impact. - Keep release notes separate from validation evidence; release notes explain what changed, while validation evidence shows whether the module claim still matches.

Algorithm implementations must remain unmodified when their CAVP evidence is reused, and the tested operational environment for the algorithm must be identical to, or fully included in, the module testing environment under the CMVP guidance. Known vulnerabilities also belong in the impact review. CMVP guidance requires vendors to track CVEs associated with the module or module components, address applicability and remediation, and update evidence during validation when security-relevant CVEs appear. - Check CAVP certificates for changed algorithms, higher-level algorithms, entropy or DRBG dependencies, and operating-environment assumptions. - Revisit approved service indicators when a service changes parameters, uses a different algorithm path, or calls an embedded validated module. - Add CVE identifiers, CPEs where available, cryptographic-service impact, mitigation plan, and rationale when a vulnerability is relevant to the module. - Do not tell customers that a module is still FIPS 140-3 validated until the certificate, Security Policy, and changed implementation agree.

Keep the record narrow: it should prove the relationship between the changed implementation and the validated module, not certify the whole product. When the source evidence is ambiguous, write that down instead of converting it into a yes-or-no claim. CMVP guidance is detailed and scenario-specific; unresolved boundary, operational-environment, dependency, algorithm, or CVE questions should stay unresolved until the vendor and laboratory evidence supports the answer. - Module identity: module name, module version, certificate number, Security Policy version, and validation status checked from public evidence. - Change summary: affected component, boundary location, software or firmware path, operating environment, algorithm path, dependency, or vulnerability. - Impact classification: no module impact shown, module evidence needs update, laboratory or vendor review needed, or customer claim must be withheld pending support. - Evidence links: Security Policy sections, service tables, CAVP certificate numbers, CVE records, release build identifiers, test report references, and public CMVP or CAVP lookups. - Publication control: approved customer wording, unsupported wording to remove, and a reviewer sign-off that the public claim does not exceed the certificate scope.
