Access Control Systems Gauteng - Johannesburg | Pretoria

Biometric, key cards and magnetic tags need to be taken into consideration when developing full proof access controls. Physical barriers such as boom gates, turnstiles and mantraps are easily integrated and automated.

Access control is a system which enables an authority to control access to areas and resources in a given physical facility. 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 information technology involved).

 

Physical access control is a matter of who, where, and when. An access control system determines who is allowed to enter or exit, where they are allowed to exit or enter, and when they are allowed to enter or exit. Historically this was partially accomplished through keys and locks.

Electronic access control uses computers to solve the limitations of mechanical locks and keys. A wide range of credentials can be used to replace mechanical keys. The electronic access control system grants access based on the credential presented. When access is granted, the door is unlocked for a predetermined time and the transaction is recorded. When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked. When a credential is presented to a reader, the reader sends the credential’s information, usually a number, to a control panel, a highly reliable processor.

The control panel compares the credential's number to an access control list, grants or denies the presented request, and sends a transaction log to a database. When access is denied based on the access control list, the door remains locked. If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door.

Security risks

The most common security risk of intrusion of an access control system is simply following a legitimate user through a door.

Often the legitimate user will hold the door for the intruder.

This risk can be minimized through security awareness training of the user population or more active means such as turnstiles. In very high security applications this risk is minimized by using a sally port, sometimes called a security vestibule or mantrap where operator intervention is required presumably to assure valid identification.

 

The second most common risk is from levering the door open.

This is surprisingly simple and effective on most doors. The lever could be as small as a screw driver or big as a crow bar. Fully implemented access control systems include forced door monitoring alarms. These vary in effectiveness usually failing from high false positive alarms, poor database configuration, or lack of active intrusion monitoring. also a system user gains access to information to which they do not have a valid need-to-know, also third parties including foreign entities,gain access to unprotected informtaion, resulting in the disclosure of sensitive information Similar to levering is crashing through cheap partition walls.

The need-to-know principle

The need to know principle can be enforced with user access controls and authorization procedures and its objective is to ensure that only authorized individuals gain access to information or systems necessary to undertake their duties. and it needs effective access control mechanisms through user identification,authorization and restricting access to systems, information and functions you must develop and maintain a set of policies,and procedures covering system users: identification authentication authorization
