Logical Access Control System
An automated system that controls an individual’s ability to access one or more computer system resources such as a workstation, network, application, or database. A logical access control system requires validation of an individual’s identity through some mechanism such as a PIN, card, biometric, or other token. It has the capability to assign different access privileges to different persons depending on their roles and responsibilities in an organization.
