Which principle restricts information access to those who need it for their job functions?

The principle that restricts information access to those who need it for their job functions is known as the "need-to-know principle." This principle is fundamental in intelligence and security practices, as it ensures that sensitive information is only available to individuals who require it to perform their specific roles or responsibilities. By implementing this principle, organizations can minimize the risk of unauthorized access to information, thereby protecting sensitive data from potential misuse or leaks.

This principle emphasizes a balance between the need for information to be shared within an organization and the need to maintain confidentiality and security. It helps to protect not only the information itself but also the integrity of the processes and individuals involved in handling that information. In various fields, such as military operations, national security, and corporate environments, the need-to-know principle plays a crucial role in safeguarding assets and maintaining operational effectiveness.
