Need to know

Restricting knowledge to specific people

The term "need to know", when used by governments and other organizations, describes the restriction of data which is considered very confidential and sensitive. Under need-to-know restrictions, even if one has all the necessary official approvals to access certain information, one would not be given access to such information, or read into a clandestine operation, unless one has a specific need to know; that is, access to the information must be necessary for one to conduct one's official duties. This term also includes anyone that the people with the knowledge deemed necessary to share it with.
