Information Security Policy
Businesses 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.
