Data Classification

Data classification assigns meaningful categories to information so protection, access, retention, sharing, monitoring, and disposal can be aligned with risk.

Purpose

Classification helps people and systems make consistent handling decisions. It should connect to actual controls rather than exist only as labels in policy.

Classification inputs

  • Business value and operational dependency
  • Legal, regulatory, contractual, and privacy obligations
  • Impact of unauthorized disclosure or change
  • Required availability and recovery
  • Data subject, owner, location, and lifecycle stage

Control connections

Classification can drive access, encryption, sharing restrictions, storage location, retention, backup, logging, data-loss prevention, and destruction.

Keep it usable

Too many categories and exceptions create confusion. A smaller model with clear examples, ownership, and automated support is often stronger than a complex scheme nobody applies.
