FIPS cybersecurity standard best practice cyber risk assessment official What is FIPS?

FIPS is an acronym that stands for Federal Information Processing Standard (FIPS)

What is a FIPS-Approved Security Method?

A security method (e.g., cryptographic algorithm, cryptographic key generation algorithm or key distribution technique, random number generator, authentication technique, or evaluation criteria) that is either a) specified in a FIPS, or b) adopted in a FIPS.
SOURCE: FIPS 196

FIPS-approved security methods include cryptographic algorithms, key generation algorithms, key distribution techniques, and authentication techniquesThese methods are used to protect unclassified government information. 

How are these methods approved? 

Examples of FIPS-approved security functions: symmetric key encryption and decryption, digital signatures, message authentication, and hashing. 

FIPS 140-2 security levels

  • Level 1Uses production-grade equipment and externally tested algorithms
  • Level 2Adds tamper-evidence and role-based authentication
  • Level 3Adds tamper-resistance and identity-based authentication

FIPS 140-3 

  • The successor to FIPS 140-2, approved in 2019
  • Testing began in 2020, and the first validations were issued in 2022
