Some people think that they only need to make sure the computer is digitally secure, but it needs to be physically secure as well.
Physical security is the tedious task of making sure that unauthorized personnel do not have access to the system. Put all the firewalls and passwords the world has on a computer but if someone can just walk in and grab it, these actions are pointless.

The easy way to keep the server safe is to keep it in a room under lock and key. Keys can easily be lost, stolen, or duplicated, which presents a problem when trying to manage user access to the servers. Another problem is keeping track of who comes in and out of the room. So limit who has keys and consider re-keying locks regularly.

Taking this problem into consideration, many businesses have shifted to a card access system. This system gives each employee a specific card that is different for each person. The benefits of this system is being able program the system to allow people into certain rooms with just one card, and it logs every time the card is swiped. For smaller firms that may not be using a server system, the new fingerprint systems that are available on PC‘s are something to look into. In smaller firms this is now affordable and should be investigated and reviewed when considering security.

We know some companies are smaller and can’t afford high tech card systems but that doesn’t mean they should leave their server vulnerable. A simple lock box server rack that’s bolted to the floor can work better for smaller companies. Remember it’s not just servers that are at risk, make sure back-up tapes are securely stored and encrypted because if they are stolen they can be restored on another system.
The best, most cost effective security is to keep the server in a locked rack that is bolted to the ground, in a locked room, with limited keys.
