Contingency
Planning: How to Get Yourself Out of Hot Water when Disaster Strikes
By Scott Cook, Director
of Customer Services for Workgroup Technology Partners
Disaster recovery is a scary
phrase that conjures up images of blizzards, fires, and hurricanes.
Yet, few business executives factor in the more common, but less
publicized incidents such as power outages and viruses in their
business contingency planning. A disaster doesn't have to be huge
to be catastrophic to a company: a sudden power outage that damages
your computer systems is problematic, but having no reliable back-up
tapes when it comes time to rebuild your system could potentially
put your company out of business. Contingency planning doesn't have
to be expensive or complicated. Here is a checklist of things you
can do now to protect your company.
Store Your Back-Up Tapes
Off-Site. Keeping a daily copy of your business data is a simple
step, yet it is so often overlooked. If your building burns down,
so do your tapes. Your system administrator should always have yesterday's
backup tapes in a safe, off-site place.
The tape rotation protocol
I recommend is to have two sets of tapes -- one set for each month
and one tape for each day. Yesterday's tape and the set of last
month's tapes should be taken home daily by someone on the IS staff.
At the end of the month, he or she brings in the second set and
takes home the first set. The key here is to always have yesterday's
tape off-site. The front seat or dashboard of your car isn't good
off-site storage facility. Common sense goes a long way here.
Some banks offer a service
for storing your backup tapes. I have one client who puts yesterday's
backup tape in her daily deposit bag, which she puts into the bank's
night deposit box. The bank stores her tape in the vault for a reasonable
monthly charge.
Create and Enforce a
Username and Password Policy. This is another step that's easy
to implement. Don't give a disgruntled employee the opportunity
to damage your network and data by having a loose or poorly enforced
password policy.
Write a password policy that
includes the following:
- Passwords are never shared amongst employees.
- Passwords should have sufficient complexity, use at least
eight characters with numbers and capital letters.
- Passwords should have a maximum age -- one month should
be sufficient.
- Enforce password history - don't let your users toggle
between two passwords.

Don't forget to disable
the account your network vendor uses after a service call is over,
too.
Protect Your Company from
Viruses, Worms and Trojan Horses. This step can be a bit expensive,
but it's still a lot cheaper than getting a virus. It is absolutely
vital that all of your computers, servers and workstations alike,
use a real-time virus protection program. Symantec and McAfee both
have products that are available for popular operating systems as
well as some specialized applications like Microsoft Exchange.
It is equally important that
the virus program is updated as much as possible. New viruses come
out every day, and if your computer gets a virus it can't recognize,
your computer will get infected. Updating is vital.
Install an Uninterruptible
Power Supply. Powerstrips will protect your computers against
power surges, but if your power goes out, your computer will crash,
sometimes causing catastrophic disk failures. At a minimum, your
servers should be running off an uninterruptible power supply.
A UPS is basically a big
battery that powers your server in case electrical power goes out.
Since your computer is running off a battery, which will eventually
run out American Power Conversion and Best Power make UPS systems
known as "Smart" UPS. Smart UPS systems will shut your server down
gracefully if you are not there to do it, say at 3:00 AM.
Maintain Physical Security
I am constantly surprised by how many computer rooms have little
or no physical security. Often the server will be out in the open
or, even worse, accessible by the public.
Someone could easily slip
a backup tape with all your company information into his or her
pocket if it is left out in the open. That same person, if given
less than a minute could configure themselves with username and
password that he could then use to gain access to your system.
Your servers should be in
a secure place and under lock and key. Minimize the number of people
that have physical access to your servers and make them accountable
for the security of the data.
Notify Administrators
of Down or Nearly Down Systems. It's a good idea to have a method
of notifying your system administrator if one of your systems goes
down during off hours. Media House has an inexpensive product that
will monitor all your servers and email, beep, or even call your
system administrator to tell her that the system is down. Some of
the more complex packages from Silverback Technologies will even
tell you what went wrong or what system is going to have problems
days in advance, which shortens downtime even more.
Build a Firewall.
A firewall typically sits between your company network and the Internet.
Without a firewall, your company's computers and servers will be
exposed to the world to see and destroy. If you have fulltime Internet
access, a high quality, correctly configured firewall is vital to
the security of your company.
Don't waste your money on
the cheap firewalls you see on sale for less than $125.00. Expect
to pay at least $1000.00 on a quality piece of equipment. Cisco
has products that are very reliable and will keep your network secure
from the bad guys. Your firewall is not a good place to skimp on
money.
Doing all these things will
not keep bad things from happening, as we just learned a few weeks
ago. But good contingency planning can take a lot of the sting out
of a bad situation and make those bad times a little less stressful.
And, it just might mean the difference between being in business,
and going out of business.
