Organizations would be wise to establish clearly
defined security and e-mail policies. More than 137,000 computer security
incidents were reported in 2003, nearly double the figure from 2002,
according to the Carnegie Mellon's Computer Emergency Response Team. The
team says that figure is expected to rise more than 50 percent again in
2004.
More than 10,000 students depend on Jill
Cherveny-Keough for trustworthy computing systems.
As director of academic computing at the New York Institute of Technology
(NYIT), Cherveny-Keough must ensure that dozens of computing centers across
the college's campuses run without a hitch. The centers, located throughout
Long Island and Manhattan, support the college's undergraduate and graduate
students.
Fall is an especially challenging season for Cherveny-Keough because of
the rapid influx of first-time network users. When returning students log
onto NYIT's network to check e-mail, account balances and registration
information, they run the risk of spreading viruses, worms and other
malicious software across the college's digital infrastructure.
Yet NYIT rarely has such problems. The reason: The college has clearly
defined security and e-mail policies in place.
Make Policy
Other organizations would be wise to follow suit. More than 137,000
computer security incidents were reported in 2003, nearly double the figure
from 2002, according to the Carnegie Mellon University's famed Computer
Emergency Response Team (CERT).
The team says that figure is expected to rise more than 50 percent again
in 2004, as spam, viruses, worms and phishing attacks increasingly plague
the Internet.
E-mail systems remain an obvious target and delivery mechanism for such
attacks. Indeed, most e-mail systems lack basic security because companies
are either too frugal or too naive to embrace secure messaging. Plus, many
employees bypass their corporate e-mail systems and instead rely on free,
unsecured public e-mail options from America Online,
Yahoo (Nasdaq: YHOO) and
Microsoft (Nasdaq: MSFT).
Don't Relax
"The recession and dot-com implosion forced many people to change jobs
multiple times in recent years," notes James Hunt, an executive recruiter in
Manhattan. "Rather than bouncing from one corporate e-mail address to the
next, some employees prefer to stick with their public e-mail accounts
because their confidants will always know where to reach them."
Still, relaxed or non-existent e-mail security policies can undermine an
organization. Moreover, lax organizations may be failing to properly comply
with Sarbanes-Oxley, the Gramm-Leach-Bliley Act (GLBA), the Health Insurance
Portability and Accountability Act (HIPAA), SEC, NASD and other federal
regulations that require companies to embrace secure messaging.
What's an organization to do? The following 10 steps -- culled from
Secure Data in Motion, dba
Sigaba,
CERT the FBI and other security-conscious organizations -- offers
a guide to getting started with secure messaging.
Take Ten Steps to Safety
- Formulate a messaging policy that is communicated regularly to all
staff members and enforced throughout your company. The policy should
clearly state proper uses of e-mail within your organization, as well as
privacy and security requirements. Include the policy in employee
handbooks and on a human resources intranet. Newly hired employees should
read and sign the policy upon joining the company. Review the policy at
least quarterly and closely monitor new compliance regulations.
- Organize e-mail training seminars to emphasize the security and
privacy risks associated with messaging. Clearly define terms such as
phishing, spam, spim (spam over instant messaging) and social engineering.
- Enforce the e-mail policy through monitoring, system checks and other
random inspections. Be sure the policy states that such steps will be
taken from time to time.
- Tell employees to be wary of unsolicited e-mail attachments, even from
people they know. Many viruses can "spoof" the return address, making it
look like the message came from someone else.
- Save and scan any attachments before opening them.
- Turn off the option to automatically download attachments.
- Investigate an open, flexible, standards-based secure messaging
system. Ideally, the security software should work with your existing
e-mail platforms, such as Exchange or Outlook.
- Insist that your security system offers baseline functionality such as
strong end-to-end encryption, mutual authentication, robust auditing
features, enterprise control and intuitive management capabilities.
- Be sure the security software requires little or no user training. The
system should offer "point-and-click" sending of secure messages with no
need for users to reconfigure their PCs or download complex software
files.
- Ensure that secure messaging is part of your company's annual IT
budget. According to Richard Clarke, former cyber security advisor to the
President, companies now spend 8 percent to 10 percent of their IT budgets
on security. Naturally, a portion of that figure should go to secure
messaging.
Follow the tips above and you'll give your executive team -- and
employees -- peace of mind as they increasingly depend on secure messaging
for mission-critical business correspondence. |
