Wireless security measures:
Every general computer networking class teaches the OSI and/or DoD networking models, and we all learn that everything begins at the bottom, with the physical level. Likewise, when it comes to IT security, physical security is the foundation for our overall strategy. But some organizations, distracted by the more sophisticated features of software-based security products, may overlook the importance of ensuring that the network and its components have been protected at the physical level.
In this article, we'll take a look at 10 of the most essential security measures you should implement now, if you haven't already done so.
#1: Lock up the server room
Even before you lock down the servers, in fact, before you even turn them on for the first time, you should ensure that there are good locks on the server room door. Of course, the best lock in the world does no good if it isn't used, so you also need policies requiring that those doors be locked any time the room is unoccupied, and the policies should set out who has the key or keycode to get in.
The server room is the heart of your physical network, and someone with physical access to the servers, switches, routers, cables and other devices in that room can do enormous damage.
#2: Set up surveillance
Locking the door to the server room is a good first step, but someone could break in, or someone who has authorized access could misuse that authority. You need a way to know who goes in and out and when. A log book for signing in and out is the most elemental way to accomplish this, but it has a lot of drawbacks. A person with malicious intent is likely to just bypass it.
A better solution than the log book is an authentication system incorporated into the locking devices, so that a smart card, token, or biometric scan is required to unlock the doors, and a record is made of the identity of each person who enters.
