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 ...
The basis for compartmentalization is the idea that, if fewer people know the details of a mission or task, the risk or likelihood that such information will be compromised or fall into the hands of the opposition is decreased. Hence, varying levels of clearance within organizations exist.
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.
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 ...
National Accreditation Board for Hospitals & Healthcare Providers, abbreviated as NABH, is a constituent board of Quality Council of India (QCI), set up to establish and operate accreditation programme for healthcare organizations. Formed in 2005, it is the principal accreditation for hospitals in India.
Included with Windows Vista and later Microsoft Windows operating systems, UAC prompts the user for authorization when an application tries to perform an administrator task. [1] Runas: A command-line tool and context-menu verb introduced with Windows 2000 that allows running a program, control panel applet, or a MMC snap-in as a different user. [2]
In information security, a confused deputy is a computer program that is tricked by another program (with fewer privileges or less rights) into misusing its authority on the system. It is a specific type of privilege escalation. [1] The confused deputy problem is often cited as an example of why capability-based security is important.
A user program on a capability-based operating system must use a capability to access an object. Capability-based security refers to the principle of designing user programs such that they directly share capabilities with each other according to the principle of least privilege , and to the operating system infrastructure necessary to make such ...
