In security terms, what does "need to know" refer to?

• A. Access based on clearance alone
• B. Access based on the importance of the information
• C. Access based on individual interest
• D. Access determined by public opinion

Answer: (B)

The concept of "need to know" in security terms refers to the principle that individuals should only have access to information that is necessary for them to perform their job or responsibilities effectively. This ensures that sensitive or classified information is protected from unauthorized access, limiting exposure to those who have a legitimate reason to use the information. Choosing access based on the importance of the information aligns with this principle, as it emphasizes that the sensitivity and relevance of the data dictate who can access it, rather than just their clearance level or personal interest. By controlling access in this way, organizations can maintain data integrity and security, reducing the risks of unauthorized disclosure or mishandling of sensitive information.
