In computer systems security, role-based access control (RBAC) or role-based security is an approach to restricting system access to authorized users. It is an approach to implement mandatory access control (MAC) or discretionary access control (DAC).. Role-based access control is a policy-neutral access-control mechanism defined around roles and privileges.

By contrast, discretionary access control (DAC), which also governs the ability of subjects to access objects, allows users the ability to make policy decisions and/or assign security attributes. (The traditional Unix system of users, groups, and read-write-execute permissions is an example of DAC.) MAC-enabled systems allow policy ...

In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other resource, while access management describes the process.The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.. Locks and login credentials are two analogous mechanisms …

Eine Access Control List (kurz ACL, englisch für Zugriffssteuerungsliste, kurz ZSL) ist eine Software-Technik, mit der Betriebssysteme und Anwendungsprogramme Zugriffe auf Daten und Funktionen eingrenzen können. Eine ACL legt fest, in welchem Umfang einzelne Benutzer und Systemprozesse Zugriff auf bestimmte Objekte (wie Dienste, Dateien, Registrier-Einträge usw.) …

In computer security, lattice-based access control (LBAC) is a complex access control model based on the interaction between any combination of objects (such as resources, computers, and applications) and subjects (such as individuals, groups or organizations).. In this type of label-based mandatory access control model, a lattice is used to define the levels of security that …

Access Control List (ACL) — liste de contrôle d'accès en français — désigne traditionnellement deux choses en sécurité informatique : . un système permettant de faire une gestion plus fine des droits d'accès aux fichiers que ne le permet la méthode employée par les systèmes UNIX.; en réseau, une liste des adresses et ports autorisés ou interdits par un pare-feu.

Discretionary access control (DAC) is a policy determined by the owner of an object. The owner decides who is allowed to access the object, and what privileges they have. Two important concepts in DAC are [citation needed] File and data ownership: Every object in the system has an owner. In most DAC systems, each object's initial owner is the ...

Law is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a science and as the art of justice. State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and ...

The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.
