What does the NIST 800-63 standard primarily focus on?

The NIST 800-63 standard primarily focuses on identity management and the processes around identity assurance. It outlines guidelines for digital identity management, particularly in how identities are validated and authenticated in online transactions and services. The standard provides a framework for establishing and assessing the level of assurance in identity proofing and authentication processes, which include aspects like credential requirements and multi-factor authentication.

While password compliance does fall under the broader umbrella of identity management, the standard is not exclusively about passwords. It encompasses various methods of identity verification, including both technical and non-technical measures. This comprehensive approach highlights the importance of secure identity practices in cybersecurity, ensuring that users are who they claim to be before granting access to sensitive resources or data.

The other options do not capture the full essence of what NIST 800-63 addresses. Features like access control models, data encryption, and network security protocols are important in their own right but do not reflect the primary focus of NIST 800-63 on identity and authentication processes.
