What is Access Control?

An access control system is a system which enables an authority to control access to areas and resources in a given physical facility or computer-based information system. An access control system, within the field of physical security , is generally seen as the second layer in the security of a physical structure.

Access control is, in reality, an everyday phenomenon . A lock on a car door is essentially a form of access control. A PIN on an ATM system at a bank is another means of access control. Bouncers standing in front of a night club is perhaps a more primitive mode of access control (given the evident lack of IT technology involved). The possession of access control is of prime importance when persons seek to secure important, confidential, or sensitive information and equipment.

Including both physical and logical safeguards, the access control system evaluates the security levels of both the user and the computer system that is to be accessed. The primary function of this control system is to act as a means of preventing access to unauthorized users. Users are assigned clearance levels, after which access is given.

Auditing and employee time and attendace features can also be provided - Complete employee details can be stored along with access details. So it can be used for time and attendance and complete reporting and auditing for employees.

Restrict access to sensitive areas - Access to unauthorized or sensitive areas can be restricted easily by alerts and alarms. Authentication methods can also be changed from time to time.

1. Track, record, and deter access throughout your organization.

3. Provide a safer working environment and customer or client environment.
4. Audit Trail showing who gained access (or denied) at any location at any time.
