Access control is often a system enabling authorities to control use of areas and resources inside a given physical facility or computer-based information system. Access control is, actually, a typical, everyday phenomenon. For example, a lock on the car door is essentially a kind of access control. The PIN over a bank's ATM method is another way of access control. Even nightclub bouncers, standing in front of your door, are another illustration of (perhaps) a much more primitive mode of access control. Using an access control mechanism is essential when persons seek to secure confidential, important, or sensitive information and equipment.
