A sailor checks an identification card (ID) before allowing a vehicle to enter a military installation. 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 ...
Computer access control. 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 ...
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 ...
Role-based access control is a policy-neutral access control mechanism defined around roles and privileges. The components of RBAC such as role-permissions, user-role and role-role relationships make it simple to perform user assignments. A study by NIST has demonstrated that RBAC addresses many needs of commercial and government organizations.
Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access ...
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 ...
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 ...
Mantrap (access control) A mantrap, security mantrap portal, airlock, sally port or access control vestibule is a physical security access control system comprising a small space with two sets of interlocking doors, such that the first set of doors must close before the second set opens. [1] [2] [3] Airlocks have a very similar design, allowing ...
