NIST SP 800-63 Digital Identity Guidelines Rev 4

The guidelines presented in Revision 4 explain the process and technical requirements for meeting digital identity assurance levels for identity proofing, authentication, and federation—including requirements for security and privacy, as well as considerations for improved customer experience of digital identity solutions and technology. The guidelines also establish identity management as a cross-functional process involving professionals representing cybersecurity, privacy, usability, program integrity, mission and business units, and other disciplines. Identity risk management in Revision 4 has continued its evolution towards a “team sport” that can more effectively address the needs of the organization and the individuals it seeks to serve.
