FIPS 140-3 defines the security requirements for cryptographic modules used to protect sensitive data. It is the benchmark for ensuring encryption is implemented and validated correctly. Non-human identities—service accounts, CI/CD pipelines, IoT devices, containers—are often overlooked in compliance checks. They hold keys, tokens, and certificates that grant direct access to APIs, databases, and customer data.
Unchecked, these identities become the weakest link. They operate without human interaction, so their credentials often remain static, reused, and underprotected. FIPS 140-3 compliance for non-human identities means every cryptographic operation uses approved algorithms, modules are validated, and keys are generated, stored, and destroyed according to strict rules. This is not optional for organizations handling regulated data: failure to comply risks legal penalties, security incidents, and lost trust.
Understanding the requirements starts with identifying where non-human identities exist in the system. Map every integration, microservice, and automated process. Replace non-compliant crypto modules with FIPS 140-3 validated libraries. Ensure key management systems meet the standard and that signing operations occur inside validated hardware security modules (HSMs) or equivalent environments. Audit logs should record every cryptographic event tied to these identities.
