Describe the concept of "need-to-know."

The concept of "need-to-know" is integral to the management and protection of classified information. It dictates that individuals can only access classified materials that are essential to the performance of their official duties. This restriction is in place to reduce the risk of unauthorized disclosures and to maintain the integrity of sensitive information.

By limiting access to only those who have a legitimate requirement for that information, "need-to-know" helps ensure that sensitive data is handled by appropriate personnel, thereby enhancing overall security. This principle underscores the importance of safeguarding national security interests and emphasizes responsible handling of classified information.
