!!! Overview[1]
The original formulation is from Jerome Saltzer:\\
''Every program and every privileged user of the system should operate using the least amount of [privilege] necessary to complete the job.''
\\— Jerome Saltzer, Communications of the ACM


In information security, computer science, and other fields, the principle of least [privilege] (also known as the principle of minimal privilege or the principle of least authority) requires that in a particular abstraction layer of a computing environment so that every module (such as a process, a user, or a program, depending on the subject) must be able to access only the information and resources that are necessary for its legitimate purpose.

[{$pagename}] is closely related to other efforts such as:
* [Law of Minimal Disclosure For A Constrained Use]
* [Need to know]
* [Privacy by Design]
* [ISO/IEC 29100|ISO 29100]


[{$pagename}] should be considered as a [Law] when designing any system.
