In the context of data management, which classification system best aligns with industry standards for data classification methods that enhance data security?

The most widely accepted system is the NIST‑based data classification framework, which divides information into Public, Internal, Confidential, and Restricted levels. This hierarchy matches the CIA triad and is used by many regulatory bodies such as ISO 27001 and HIPAA. By assigning each data set a clear level, organizations can apply the appropriate controls—like encryption for Restricted data or limited access for Confidential data. For example, a patient’s medical record would be classified as Restricted, triggering encryption, audit logging, and strict access limits. This structured approach is the industry standard for protecting sensitive data.
