What is FIPS 140-2? Cryptographic Module Validation Program
FIPS 140-2 is a federal information processing standard that manages security requirements for cryptographic modules. The National Institute of Standards and Technology (NIST) published the security standard in November 2001 to develop coordinated requirements for hardware computer components. NIST replaced FIPS 140-2 with FIPS 140-3 in March 2019. This iteration introduced new critical security parameters for software and firmware and updated the four critical security levels that FIPS 140-2 introduced.
