Data Classification: Public to Top Secret, Sensitive to Restricted (3.3)

July 15, 2026 · 16 min

Show notes

This episode covers data classification labels and how they guide security decisions. Students should recognize common labels such as public, sensitive, confidential, restricted, critical, secret, and top secret, while understanding that exact labels vary by organization and industry. Classification helps determine who can access data, where it may be stored, whether it must be encrypted, how it should be transmitted, how long it should be retained, and how it must be disposed of. For the exam, students should connect classification to handling requirements, access control, data loss prevention, privacy, compliance, and incident impact. Misclassified data can lead to overexposure, unnecessary cost, or failure to protect regulated information.
