Lock Up Your
Servers!
Jason Appel,
Security Practice Manager, Sage Computer
One aspect
often overlooked when securing our information is physical
security. The goal of physical security is to control who
can walk up to the information and touch it. The idea is to
prevent unwanted information disclosure, loss, or
corruption, the same as when securing the information across
the network or from the internet. The difference is that
physical security deals with the “real world".
For most of us,
this doesn't mean training your Chihuahua as an attack dog
or outfitting your employees with dark shades, cheap suits
and sleeve microphones; it simply means using some common
sense.
Before we can take measures to physically secure our
information, we need to know what type of information needs
to be protected. There is no need to post armed guards
around your product catalog after it's been published: it's
meant to be seen by others. Before it's published could be a
different story as you may not want your competition getting
a sneak peek. In other words, we need to classify our
information.
While there are
many excellent information classification schemes, they all
boil down to one question: who needs to have what level of
access. The rest is deciding how to limit access to just
those people. With this in mind, there is one common sense
step we can take to beef up our physical security in the
typical small office. Lock it up.
While it may be
true that "a locked door only stops an honest man", locks go
a long way towards letting people know what is out of
bounds. If the file cabinet has sensitive information in it,
lock the cabinet or put it in a locked room.
If your network
server is vital to your business operations, make sure it's
locked up to limit who has access to it. Remember, loss of
services such as email, files, printing, faxing, and
internet can mean the loss of access to vital information.
Thus tripping over the server's power cord could be
classified as a "Denial of Service" (DoS) attack.
Sometimes, it's
just as important to have taken all reasonable steps to
secure the information, as it is to actually prevent
unauthorized access to it.

uncomfortable with the way you are currently classifying
your information or concerned about locking up your servers,
