Computers: Protecting Confidential Client Information

Laptop computers
present special data security risks because they are designed for
mobility and are frequently used outside the office. Some of the
risks associated with laptop usage are:
- Loss and
Theft. Laptops are vulnerable to both human error (loss) and to
greed (theft). The portable nature of laptops makes them easy
to leave in a hotel room, airport, or restaurant. They are also
easily stolen and sold on the black market. National crime statistics
report that roughly 150,000 laptops were stolen in 1994, 200,000
in 1995, and 275,000 in 1996. Theft is growing faster than the
number of laptop computers in use. Theft from an office is the
most common, and airport theft the second most common.
- Unauthorized
Access. Laptop computers are frequently used in insecure locations
– conference rooms, temporary offices, and airports, to
name a few. In most cases, the laptop is used in a conference
room or other public area where the laptop user is not well known
to others in the area. This situation makes it easy for an unauthorized
user to view or use the laptop without looking suspicious. Be
especially careful if you are using a high-quality large screen,
as this allows a much wider viewing angle.
- Unauthorized
Use of Data. Unauthorized use of data usually results from: (a)
loss or theft of the laptop; (b) unauthorized access to the laptop
for long enough to view or copy data; (c) loss or theft of data
copied to diskettes or other portable storage devices (e.g., memory
sticks, USB drives) for printing, backup, or data transfer; or
(d) interception or compromise of data transmitted over telephone
lines or the Internet.
These security
risks cannot be eliminated, but a combination of technology tools
and user awareness can reduce laptop data security risks to a reasonable
level.
PHYSICAL SECURITY
The risks of
theft, unauthorized access, or unauthorized use of data can be significantly
reduced by diligently observing the following physical security
practices:
• Use
a sturdy bag that doesn’t look like a laptop bag to carry
your laptop;
• Hang
the bag from your shoulder or keep in on the floor between your
feet;
• Use
locking cables or burglar alarms;
• Never
leave the laptop unattended or out of your sight in a public place;
• Don’t
check the laptop as luggage or in a coatroom;
• Don’t
store the laptop in airports, airplanes, trains, or subways;
• Keep
the laptop with you when in taxis, cars, or other transportation;
• Watch
the laptop as it goes through airport metal detectors (“snatch
and grab” thefts are common); and
• Use
locking or even unlocked drawers or cabinets to store laptop computers
when you leave an office, conference room, or hotel room.
ACCESS SECURITY
The second line
of defense against laptop theft or unauthorized use of data is access
security. If a laptop computer is lost, stolen, or otherwise outside
the control of its owner, data remains secure if an unauthorized
person is prevented from turning the computer on and using it.
The simplest
way to reduce access to your computer data is to log off of the
computer when you are not able to stay near it, and to take the
computer with you. Since this option is not always practical, you
can also protect the data by using the lock computer function of
the computer. Simply hit Ctrl-Alt-Del while your computer is on,
then select Lock Computer. Your laptop is now locked until an authorized
user logs on.
Password security
options include using password protection on screen savers (so a
password is needed once the screensaver appears), using a password
that guards against being easily guessed (often referred to as a
“strong” password), changing passwords regularly, and
following the other security suggestions that are available from
the maker of your operating system. If you use Microsoft Windows,
you can find a list of security tips by searching the Help menu.
DATA SECURITY
Access security
alone is not sufficient protection for laptop computers. Power-on
and screen-lock passwords can be eluded by removing a laptop’s
hard drive and reinstalling the hard drive in another laptop, and
neither system protects data being transmitted by CD, memory sticks,
portable hard drives, or e-mail. Using security software and hardware
security devices provides additional data security. An example of
security software that includes e-mail encryption is Steganos Security
Suite, reviewed in the September 2003 issue of PC World. Examples
of hardware security devices are DEFCON Authenticator (reviewed
by David Hiersekorn for the June/July 2003 issue of Law Office Computing)
and MemoPass. These devices create and store personal profiles for
the authorized user through a USB port or by access card.
Creating
a mobile system can backfire if the system is not secure. This is
a very important consideration when using a wireless connection.
Wireless laptops and computers have wireless adapters and wireless
access ports that enable them to connect to your computer network.
Unfortunately, these wireless access ports transmit radio signals
continuously. Since only about one percent of wireless users change
the vendor’s default user name and configurations, 99 percent
of these wireless access points are highly insecure. So if you are
using a wireless network, don’t rely on the default settings
of your laptop to protect you. Check with your wireless vendor or
consult with an expert about how to properly secure your wireless
system.
Last, but not
least, laptop users can secure data by being selective about what
they store on the laptop. If possible, avoid storing personal information
(such as birth dates and social security numbers) on a laptop. When
working away from the office, use resources that the computer can
link to via the Internet as the sources of confidential data. Intranets,
extranets, and Web sites protected by private passwords are examples
of such sources not located on a laptop’s hard drive. If the
laptop is lost or stolen, the client data will not be compromised.
This is particularly true if you don’t store the passwords
to such resources on the laptop itself, or if the passwords are
well encrypted to prevent unauthorized access.

RELATED
ISSUES:
1. Do
you know the security level of your computer?
You may have
taken every step possible to protect your computer from online security
risks, but how do you know if your precautions work? One way is
to test your computer’s security with Symantec Security Check.
This quick, free online tool, found on the Web at www.symantec.com/securitycheck,
runs a quick security scan of your computer to search for any security
holes. Once completed, you’re presented with a report of any
problems and suggestions on how to fix them. Even if you use other
security products, the Symantec Security Check is a good way to
make sure you’re protected.
2. What
to do about stolen or lost client files.
You leave the
office. It’s a typical busy day, and you take a few files
with you to work on at home. On the way, you stop at the grocery
store to pick up a few items. On returning to the parking lot, you
realize your car has been stolen. As you call the police and your
insurance company to report the incident, you realize that your
client files (possibly on your laptop) were in the car…
If
this or a similar nightmare happens to you, call Legal Mutual to
report the incident and to discuss how best to handle the situation
with your client. It is important to let your client know that the
file has been lost or stolen and that you will be reconstructing
the file. In addition, if your file, briefcase, or laptop contained
social security numbers, birth dates, or other information that
would allow someone to steal your client’s identity, your
client will need to know in order to take the appropriate precautionary
steps.
If your files
are lost or stolen, contact your business insurance broker or carrier
to see whether your business policy covers you for the cost of reconstructing
the file. This type of coverage is often included in your property
coverage and may be referred to as Valuable Papers coverage.
The property
coverage of your business insurance is also the coverage that would
apply to replacement of stolen laptops, although, depending on your
coverage, exclusions and/or deductibles may apply.
To make sure
you have the level and type of coverage you want, contact your insurance
broker. A wide range of coverage limits and business coverage packages
are available. Premiums will vary based on the desired type of coverage,
limits of insurance, and deductible.
