FIPS 140-3 — Security Requirements for Cryptographic Modules
SmartSuite provides the system for managing controls, evidence, mappings, assessments, and reporting. Framework text may require a separate license unless explicitly provided.
Overview
FIPS 140-3 is a U.S. government standard that establishes security requirements for cryptographic modules protecting sensitive but unclassified information.
Why it Matters
FIPS 140-3 establishes verified standards for cryptographic modules, helping organizations protect sensitive data and meet security obligations.Key benefits include:
- Strengthen data protection practices
Ensure cryptographic solutions effectively safeguard sensitive but unclassified information across diverse hardware and software environments.
- Enhance regulatory compliance
Demonstrate adherence to government and industry security requirements, enabling smoother audits and facilitation of contractual obligations.
- Enable robust risk management
Support identification, assessment, and mitigation of data security risks through comprehensive requirements for cryptographic module validation.
- Improve operational resilience
Increase reliability and continuity of business operations by reducing vulnerabilities in cryptographic mechanisms that underpin critical systems.
- Increase audit readiness
Provide validated evidence of cryptographic control effectiveness, streamlining external and internal audit processes.
How it Works
FIPS 140-3 structures its requirements around the security of cryptographic modules, organizing these into distinct security levels and eleven functional areas including physical security, cryptographic key management, and self-tests.
Key Elements
- Module Security Levels
Defines four progressive security levels to categorize cryptographic modules based on increasing rigor and controls.
- Cryptographic Module Specification
Establishes requirements for construction, interfaces, and documentation of cryptographic modules used to secure data.
- Physical Security Mechanisms
Describes physical protections applied to cryptographic modules to deter unauthorized physical access or tampering.
- Key Management Processes
Outlines methods for the generation, storage, distribution, and destruction of cryptographic keys within modules.
Framework Scope
FIPS 140-3 is adopted by federal agencies, regulated industries, and technology providers responsible for protecting sensitive but unclassified data.

Frequently Asked Questions For FIPS 140-3 (Security Requirements for Cryptographic Modules)
FIPS 140-3 is used to define security requirements for cryptographic modules protecting sensitive but unclassified information in government and regulated industry systems. It ensures that cryptographic mechanisms meet stringent standards for confidentiality, integrity, and authenticity. Implementation of FIPS 140-3 is essential for compliance with federal cybersecurity requirements.
FIPS 140-3 validation is mandatory for cryptographic modules used in U.S. federal agencies and often required by contractors and regulated industries. Only modules listed as validated by NIST through the Cryptographic Module Validation Program (CMVP) are considered compliant. Organizations operating in federally regulated environments typically must use validated cryptographic modules.
FIPS 140-3 applies to IT systems within U.S. federal agencies and organizations handling federal data, including government contractors and regulated industries such as healthcare and finance. It covers use cases where cryptographic modules are deployed to protect sensitive but unclassified information. The standard can also be referenced by private sector entities for best practices.
FIPS 140-3 defines four security levels, each with increasing requirements for physical security, module authentication, tamper-resistance, and key management. Level 1 provides basic protections while Level 4 offers the most comprehensive safeguards, including robust defenses against physical and environmental attacks. Organizations select the appropriate level based on their risk profiles and regulatory needs.
Vendors submit cryptographic modules for testing by accredited laboratories under the CMVP. Assessment covers areas such as key management, physical security, authentication, self-tests, and tamper-resistance. Upon successful validation, modules are listed on the NIST validated modules list, confirming their compliance with FIPS 140-3.
FIPS 140-3 is often referenced in conjunction with frameworks such as NIST SP 800-53, which outlines broader security controls for federal information systems. While FIPS 140-3 focuses narrowly on the technical standards for cryptographic modules, it supports compliance with higher-level requirements found in broader risk management and cybersecurity frameworks.
Organizations must ensure that only NIST-validated cryptographic modules are deployed, track module versions, and monitor for status updates or revocation. Regular reviews of cryptographic inventories, documentation of compliance evidence, and readiness for audits are necessary to maintain ongoing FIPS 140-3 compliance.
SmartSuite enables organizations to track the deployment and status of FIPS 140-3 validated cryptographic modules, manage associated cryptographic policies, collect compliance evidence, and document control implementation. It facilitates audit readiness by centralizing evidence and providing reporting tools, helping organizations demonstrate adherence to federal standards and monitor compliance over time.
