The National Institute of Standards and Technology (NIST) has introduced the NIST Privacy Framework to standardize best practices for privacy programs. The framework was developed through working sessions as well as by seeking commentary from privacy and security practitioners.
There are three elements to the framework: Core, Profiles, and Implementation Tiers.
