("The rise of physical security information management", 2007) The traditional physical security systems such as human surveillance and locks and boundaries are being integrated with the modern IT systems. The modern IT physical security measures such as video surveillance/ closed circuit TV, token based access control systems are becoming much more popular and even small businesses are using these systems.
The present research paper deals with some of the traditional physical security system such as building and ground security, access control system and perimeter security. The principles behind these security systems have also been discussed. Some of the possible future physical securities systems have also been covered up.
The principle of the building and ground security is to stop the intruder from entering the ground or building area where the intruder can take away or damage the valuables. By the available means, we have to stop the intruder outside the ground or building and at the same time the authorized person or employee should not be de-motivated by the procedure.

So, the terminal or gate will open only when the identity of the person is confirmed by network.

In actual these access control systems are similar to automated capture and access systems that have been used for meetings (Moran, Palen, Harrison, Chiu, Kimber, Minneman, van Melle and Zellweger, 1997). The access control systems were also been used for personal memory aid tools since long time (Hayes, Patel, Truong, Iachello, Kientz, Farmer and Abowd, 2004). The advantage of these access control system is that a trespasser cannot enter inside the premises, however the main disadvantage being that even a minor change in the physical feature such as fingerprint will deny the entry of the genuine employee or the visitor.

Perimeter Security:
