that do not have clearly written Information Technology
security policies and practices in place run the
risk of being named in legal actions in the very
near future. Although no current court cases exist,
many security experts are warning that if you lose
or expose confidential business or customer data,
unknowingly distribute viruses or experience a breach
of your systems that results in loss of service
to your customers, you could be found liable.Computer
and network security used to be the concern of only
the largest corporations.
Now, however, with the high availability
of networks, web hosting and Internet applications
to even the smallest office, the tide is turning.
Today, a small business with two employees can
construct an economical network, share a cable
modem and purchase a firewall, which enables remote
access using a Virtual Private Network (VPN).
This is also a double-edged sword. This new "high
availability" has also born a vast breed of crackers.*
These individuals can find ways to access, steal
and/or destroy data residing on public and private
networks. Starting th Process The key to establishing
these policies and practices is to not be overwhelmed
by the complexity of the process.
Start by taking inventory of your
systems, connections to the Internet and external
providers, the method in which you store data
and the method in which you secure and backup
data. During this documentation process, you can
identify clear procedures for the handling and
transfer of this data, as well as new security
measures you can use to show due diligence in
addressing any potential security risks.
The Basics
Even the smallest network should adhere to the
following: Never use a computer system for
both personal and business use (i.e. family uses
for fun, but business is also processed on the
machine). This is an immediate risk to public
disclosure of confidential information and accidental
loss of data. A daily and monthly data backup
process should exist which also provides for off-site
or fireproof storage of the backup data in a non-editable
format (i.e. offline magnetic tape or CD-R (not
CD-RW)). Any connection to the Internet,
from a shared 56 K modem to a broadband (DSL,
Cable or T1) connection, should be behind a software
or hardware-based firewall. If not, this is an
immediate and gaping hole through which crackers
can access your private network or use your computer
for an attack on a larger public or private network
(often called a DDOS or Distributed Denial of
Service attack).
Use a password to login to your
computer even if it is not on a network. Passwords
should be at least eight characters and changed
as often as tolerable (90 days is a satisfactory
time period). Use and update daily an anti-virus
software suite, which can protect your individual
computers as well as any servers you use. By taking
these steps, you are dramatically reducing your
exposure to uninvited intrusions. The inventory
you established earlier can then be reviewed and
a plan can be developed by your business and your
technology staff/consultant to ensure your office
network and data is a fortress with a little risk
as possible.
