The Libraries' Digital Library Services department is involved in a retrospective digitisation project of all UCT theses. The aim is that all UCT's Master's and Doctoral theses, dating back to 1929, will be available via OpenUCT. ZivaHub is the University of Cape Town's institutional open access data repository. It houses scholarly outputs such ...
Attribute-based access control (ABAC), also known as policy-based access control for IAM, defines an access control paradigm whereby a subject's authorization to perform a set of operations is determined by evaluating attributes associated with the subject, object, requested operations, and, in some cases, environment attributes.
A database management system, in its access control mechanism, can also apply mandatory access control; in this case, the objects are tables, views, procedures, etc. In mandatory access control, the security policy is centrally controlled by a policy administrator and is guaranteed (in principle) to be enforced for all users.
It is a security system that provides access control and auditing functionality for the z/OS and z/VM operating systems. RACF was introduced in 1976. [1] Originally called RACF it was renamed to z/OS Security Server (RACF), although most mainframe folks [who?] still refer to it as RACF. [2] Its main features are: [1]
In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [1] Each entry in a typical ACL specifies a subject and an operation.
Components of an access control system include: An access control panel (also known as a controller) An access-controlled entry, such as a door, turnstile, parking gate, elevator, or other physical barrier; A reader installed near the entry. (In cases where the exit is also controlled, a second reader is used on the opposite side of the entry.)
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.
Distributed Access Control System (DACS) [1] is a light-weight single sign-on and attribute-based access control system for web servers and server-based software.DACS is primarily used with Apache web servers to provide enhanced access control for web pages, CGI programs and servlets, and other web-based assets, and to federate Apache servers.
