PURPOSE Classifying information helps people decide how to store, share, and protect it. COMMON LEVELS Typical levels include public, internal, confidential, and restricted. Names may vary, but the idea is to match protection to risk. HOW TO CLASSIFY Consider who should see the information, what harm could occur if exposed, and whether laws, contracts, or policies apply. WHEN UNSURE Choose the more protective classification until the data owner confirms. BEST PRACTICE Mark sensitive documents clearly when possible.
