What is the function of a system of record (SOR) in identity management?

In identity management, a system of record (SOR) serves as the authoritative repository for identity data. This means it is recognized as the trusted source where the most current and accurate identity information can be found. The role of an SOR is critical because it provides consistency across various systems that may rely on identity data for access control, compliance, and security purposes. When organizations need to verify or retrieve identity information, they refer to the SOR to ensure they are using the most reliable data available.

Having a centralized and trusted source for identity information helps mitigate risks associated with unauthorized access and ensures that identities are properly managed throughout their lifecycle. The SOR plays a vital role in maintaining data integrity and providing a clear reference point for other systems that may use this data for authentication and authorization processes.
