What classification levels are defined and how should they be applied?

• A. Public, Internal, Confidential, and Restricted, with handling rules corresponding to each classification level.
• B. Public, Internal, and Confidential only.
• C. Top Secret, Secret, Confidential, and Public.
• D. Only Public and Internal.

Answer: (A)

A tiered classification system assigns each piece of information a sensitivity level and then applies specific handling rules for that level. The key idea is to protect information proportionally to its risk if exposed, shared, or lost. The best answer reflects a four-level scheme: Public, Internal, Confidential, and Restricted, with distinct handling guidelines for each one. This setup ensures there are defined protections for every level, so information isn’t inadvertently treated as if it were less sensitive or more protected than intended. Applying these levels means labeling documents, controlling who can access them on a need-to-know basis, using appropriate controls (such as encryption or extra safeguards for higher levels), and following proper storage, transmission, and disposal procedures aligned with each level. By having clear, defined rules for each level, the organization can consistently protect information across all contexts. Other options miss either a level, or introduce levels not defined by the standard, which would weaken the consistency and effectiveness of the protection scheme.
