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.
RBAC is a flexible access control technology whose flexibility allows it to implement DAC [6] or MAC. [7] DAC with groups (e.g., as implemented in POSIX file systems) can emulate RBAC. [8] MAC can simulate RBAC if the role graph is restricted to a tree rather than a partially ordered set. [9]
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.
Another form of access control (procedural) includes the use of policies, processes and procedures to manage the ingress into the restricted area. An example of this is the deployment of security personnel conducting checks for authorized entry at predetermined points of entry.
