Digital Dispatch – Is the Internet Safe?
by Todd Althouse
The simple answer is no. Most of the computers today are vulnerable to some kind of hacker or
virus attack. If you don’t believe me, just pickup any newspaper or listen to any news show,
computer attacks happen everyday. Should you stop using the Internet? ABSOLUTELY NOT! With the
proper precautions you can adequately secure your information. In fact, I read a statistic the
other day that said more data is lost from computers being stolen than from data being accessed
from the Internet.
Then why should you use a computer connected to the Internet? - To stay profitable. Many of your
competitors already manage their businesses using a computer. Today, most of the motorclubs
encourage service providers to use the Internet to receive calls. Tomorrow this may become a
requirement. In fact, the Internet will soon be used by car dealers, trucking companies (www.wrecker.com), car rental agencies, and insurance
companies to send the majority of towing requests. Therefore, it is imperative that you protect
your information from malicious Hackers.
Just like we use locks on our doors and windows to prevent intruders, we can lock down the
information on our computer. However, just as it is difficult to absolutely prevent someone from
entering your house, it is difficult to absolutely prevent someone (a hacker) from gaining access
to your computer. That is why backups (your insurance) are so important. So, if you are attacked
you can restore your information.
The same way banks protect your money and valuables in high security vaults, professional system
administrators protect your data by preventing nearly all attacks from hackers, losses from fire,
storms or theft with the proper hardware and software, but it is expensive. The average computer
owner is not willing or not able to go to this expense. So my article is aimed at affordable
solutions that will give you adequate protection against viruses and hackers.
Let’s start with a few definitions:
Hacker (or more correctly a Cracker): Is a programmer who breaks into a computer system for the
mere challenge of doing it. This may or may not be a malicious attack.
Viruses and Trojan Horses: Viruses are computer programs that run against your wishes and
without your knowledge. Some cause damage to your system, while other are just annoying. A Trojan
Horse, a special kind of computer virus, is a malicious program that is disguised as a useful or
fun program. It can be installed on your computer by email or other means. Someone can send you an
email with an attachment claiming that it is a super duper screen saver or another appealing
document. When you launch the attachment it appears as if nothing has happened, but in reality the
Trojan has been installed and initialized on your system. It can be a remote control type of
program, which will allow someone to control your computer, access your data or delete things.
Usually the anti-virus vendors are on top of threats like this and issue a new virus definition
that detects the Trojan before it can do any harm. That is why it is very important to keep your
anti-virus software up-to-date.
Firewall: A software program or hardware device that monitors Internet activity to detect and
prevent unauthorized access to a computer system.
Are you at risk?
There are several FREE resources that will test the vulnerability of your computer system to
outside attacks:
These programs will also identify other areas of concern and rate your exposure. They will also
give instructions on minimizing your risks, like:
Disabling File and Printer sharing for Microsoft Networks
This is a Windows networking setting that should be disabled (off) unless you are behind a
firewall. If you have this enabled (on) anyone can access the data on your computer hard drive.
Look in the Microsoft Windows help file under “File and Printer Sharing for Microsoft Networks” for
instructions on disabling it.
Using better passwords
Do not use proper names, since many of the password cracking programs assume that most people
use the names of their spouse, kids, pets, etc. You should also mix upper and lower case letters
with numbers. The more random you make the sequence the better. For example “rfghZyU23Iu” is hard
to crack, but it is also hard to remember. Think of it as remembering a combination to a lock or a
phone number. You can remember it with a little practice.
Consider purchasing a personal firewall (Free - $40)
A personal firewall program will limit your exposure to unwanted guests by monitoring all
Internet activity. The next version of Microsoft Windows (Windows XP) will have a personal firewall
integrated into the operating system.
Service providers are being told that the motorclub Digital Dispatch will not work behind a
firewall. While this may be true for the web solutions from the motorclubs, it is not true for the
solutions being provided by the towing software vendors. Furthermore, I believe with a little
investigation and testing the motorclub browser solution should work behind a firewall too.
But is it safe to use Digital Dispatch? Although Digital Dispatch uses the Internet, it poses a
relatively low security risk if properly implemented. This is because data is expected in a certain
format, if does not receive data in that format it rejects the packet. However, your towing
software vendor should also verify that the data packet came from one of the motorclubs and the
connection should not remain open for more than a few seconds. These precautions will keep your
risk exposure to a minimum.
Purchase an anti-virus program and keep it up-to-date
Most anti-virus programs have a “live update” feature that will check the company’s web site for
virus updates and update the software when needed. You need to do this about every 2 weeks to make
sure you are protected against the latest viruses. You can order an anti-virus program online from
http://www.mcafee.com or http://www.symantec.com.
Give Credit Card information on a secure site only
You can tell you are on a secure site by looking for “locked padlock”. Netscape places the
padlock in the lower left corner and Internet Explorer places the padlock in lower right corner of
the program screen. Giving your credit card information over the Internet on a secure site is more
secure than giving your card over the phone or even using you card in a store. This is because your
credit card information is usually sent directly to the credit card company, bank, or processing
company without human intervention.
Use online applications (ASPs)
The next generation of applications for towing management, accounting (Quickbooks for the Web),
anti-virus, etc. will be online. This will give tremendous security advantages. First of all,
Internet professionals that know how to thwart the efforts of hackers will maintain the sites. Your
data will be safer on the web than in your own office. Secondly, if you were to get a virus or your
computer is lost or stolen, all of your data would be safe on the server of your application
service provider. Therefore, since nothing is stored on your local computer, you can simply go to
another computer, input your password and you are back in business without experiencing any
downtime or lost information.
Use secure databases to store your information
If you are using a towing management or accounting software, your data is stored in databases.
Think of a database like a file cabinet. Some people lock their file cabinets and others do not.
Databases are locked using user IDs and passwords. Just because your program requires you to login
with a password, this does not mean the database is protected. Certain older less expensive
database systems allow access to your information from outside the software that created it (using
something like Microsoft Excel). However, expensive enterprise (professional client/server)
database systems, such as SQL Server and Oracle maintain a very high level of security. That is to
say, without the proper user ID and password, it is nearly impossible to view your information.
This is not the case with older (distributed) databases, such as FoxPro and dBase. These packages
merely store information and do not require authorization to view the information. They rely on
your local network to provide the security.
The Internet generation of towing software (ASPs) will likely use professional client/server
databases for information storage. This will bring a level of security to your information that has
been needed for a long time.
To review, you should do the following to reduce your Internet risk:
Using computers, the Internet, and proper safeguards, your business information will be more
secure and accessible. Your competitors will have a tough time catching up!
