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 ...
Separation of privilege: Where feasible, a protection mechanism that requires two keys to unlock it is more robust and flexible than one that allows access to the presenter of only a single key. Least privilege: Every program and every user of the system should operate using the least set of privileges necessary to complete the job.
Patient safety work product includes any data, reports, records, memoranda, analyses (such as root cause analyses), or written or oral statements (or copies of any of this material), which are assembled or developed by a provider for reporting to a PSO and are reported to a PSO; or are developed by a patient safety organization for the conduct ...
In general, capability systems do not allow permissions to be passed "to any other subject"; the subject wanting to pass its permissions must first have access to the receiving subject, and subjects generally only have access to a strictly limited set of subjects consistent with the principle of least privilege.
A number of computer operating systems employ security features to help prevent malicious software from gaining sufficient privileges to compromise the computer system. . Operating systems lacking such features, such as DOS, Windows implementations prior to Windows NT (and its descendants), CP/M-80, and all Mac operating systems prior to Mac OS X, had only one category of user who was allowed ...
Epidemiological assessment may include secondary data analysis or original data collection — examples of epidemiological data include vital statistics, state and national health surveys, medical and administrative records, etc. Genetic factors, although not directly changeable through a health promotion program, are becoming increasingly ...
Consider this quote: "Least privilege has also—and arguably incorrectly—been interpreted in the context of distribution of discretionary access control permissions, even to the point of asserting that, e.g., giving user U read/write access to file F violates least privilege if U can complete his authorized tasks with only read permission."
