In 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 .
Logical access controls enforce access control measures for systems, programs, processes, and information. The controls can be embedded within operating systems, applications, add-on security packages, or database and telecommunication management systems. The line between logical access and physical access can be blurred when physical access is ...
Discretionary access control. In computer security, discretionary access control ( DAC) is a type of access control defined by the Trusted Computer System Evaluation Criteria [1] (TCSEC) as a means of restricting access to objects based on the identity of subjects and/or groups to which they belong. The controls are discretionary in the sense ...
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. [1]
The meta-data model of the control sub-process is based on a UML class diagram. Figure 2.1.2 shows the metamodel of the control sub-process. Figure 2.1.2: Meta-process model control sub-process The CONTROL rectangle with a white shadow is an open complex concept. This means that the Control rectangle consists of a collection of (sub) concepts.
Mandatory access control. In computer security, mandatory access control ( MAC) refers to a type of access control by which a secured environment (e.g., an operating system or a database) constrains the ability of a subject or initiator to access or modify on an object or target. [1] In the case of operating systems, the subject is a process or ...
Access control matrix. In computer science, an access control matrix or access matrix is an abstract, formal security model of protection state in computer systems, that characterizes the rights of each subject with respect to every object in the system. It was first introduced by Butler W. Lampson in 1971. [1]
NIST Special Publication 800-53 is an information security standard that provides a catalog of security and privacy controls for all U.S. federal information systems except those related to national security. It is published by the National Institute of Standards and Technology, which is a non-regulatory agency of the United States Department ...
