What is a primary characteristic of classified information?

Classified information is a type of information that requires protection due to its sensitive nature. A primary characteristic of classified information is that it necessitates a security clearance for access. This means that only individuals who have undergone a thorough background check and have been granted the appropriate level of clearance are authorized to view or handle this information.

Access controls are imperative for maintaining national security and protecting sensitive data from unauthorized disclosure. Therefore, the requirement for a security clearance serves as a critical safeguard to ensure that only vetted individuals can access potentially harmful information.

The other characteristics mentioned do not align with the nature of classified information; it is not available to the general public and cannot be freely shared among employees without proper authorization. Additionally, classified information is not limited solely to upper management but can pertain to various levels and roles in an organization, as long as individuals have the necessary clearance.
