Lock up
your servers!
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. 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.
If you are uncomfortable with the way you are currently
classifying your information or concerned about locking
up your servers, feel free to contact us at 578-9739.
