In information security, computer science, and other fields, the principle of least privilege (PoLP), also known as the principle of minimal privilege (PoMP) or the principle of least authority (PoLA), requires that in a particular abstraction layer of a computing environment, every module (such as a process, a user, or a program, depending on the subject) must be able to access only the ...
A common method to implement privilege separation is to have a computer program fork into two processes. The main program drops privileges, and the smaller program keeps privileges in order to perform a certain task. The two halves then communicate via a socket pair. Thus, any successful attack against the larger program will gain minimal ...
Normally, applications use system.privilege.admin, but another may be used, such as a lower right for security, or a higher right if higher access is needed. If the right the application has is not suitable for a task, the application may need to authenticate again to increase the privilege level.
Medical ethics is based on a set of values that professionals can refer to in the case of any confusion or conflict. These values include the respect for autonomy, non-maleficence, beneficence, and justice. [2] Such tenets may allow doctors, care providers, and families to create a treatment plan and work towards the same common goal. [3]
Privilege escalation is the act of exploiting a bug, a design flaw, or a configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user.
Honoring the Principle of least privilege at a granularity provided by the base system such as sandboxing of (to that point successful) attacks to an unprivileged user account helps in reliability of computing services provided by the system. As the chances of restarting such a process are better, and other services on the same machine aren't ...

A textbook formulation is: "People are part of the system. The design should match the user's experience, expectations, and mental models." [13]The principle aims to leverage the existing knowledge of users to minimize the learning curve, for instance by designing interfaces that borrow heavily from "functionally similar or analogous programs with which your users are likely to be familiar".
