special report: technology By Elizabeth Geldermann, of SBT
When
several computer viruses took over the computer systems of a local tax
consulting firm, the employees were unable to use their computers, and
they were concerned that vital information about their clients would be
compromised. The business owner had not implemented a security
infrastructure into the companys computer system because employees had
been told not to surf the Internet or open e-mail attachments from
unknown recipients.
However,
an attack still occurred.Several days, and several dollars later, the
company was back up and running, this time with security."We took a
layered approach to security," said Raj Chandra, a wireless
optimization engineer for Milwaukee-based NetSolutions Corp., which set
up the new security system for the company. "We protected their
perimeter, we ensured their local resources were secure and we enforced
security policies, including changing vital information on a regular
basis and quarterly checks on their network security. For obvious
reasons, we cannot give out the company name."
Business
computer systems are becoming increasingly vulnerable to such attacks,
according to information technology industry experts, and many business
owners have misconceptions about their chances of becoming targets for
hackers, viruses and security breaches. "People used to say that if a
new company survived after two years, they were fortunate, but now with
viruses and a lack of protection, companies are going down a lot
sooner," said Laverne Ihm, chief executive officer of NetSolutions. "A
lot more companies are going belly up because they dont have
protection."
Some
clients that NetSolutions has worked with made every employee an
administrator in their system, which makes internal security an issue,
Chandra said. "Company information needs to be on a right-to-know and
need-to-know basis to eliminate liabilities for a business," said
Jeremy LaSage, president and principal consultant for NetSolutions.
Small
Business Information Security Readiness, a study conducted this year by
the Small Business Technology Institute, revealed that most owners of
small businesses are not protecting themselves from possible internal
or external security threats. The study was sponsored by Symantec Corp.
a Cupertino, Calif.-based security partner for businesses. The study
found that small businesses are becoming more vulnerable to information
security threats or breaches as the businesses continue to invest in
upgrading technology and mobilizing employees.
"Small
businesses are largely unaware and uneducated about information
security risks and their economic repercussions, and they have a
complacent and passive attitude towards information security
protection," the studys key findings said. At least 40 percent
of the small businesses surveyed use networks and mobile devices, but
less than one third of small businesses increased their security
spending in the last year, according to the study, which surveyed more
than 1,000 small businesses that employed 1 to 10 employees.
"We
see trends where bad guys are looking more at small businesses as
targets," said Kraig Lane, group product manager for Symantec. "Small
businesses have the same type of customer data as big companies, but
appear to be less protected. It is the same mentality of a criminal
that would rob a convenience store or liquor store instead of a bank."
Chandra said some business owners think that if they are farther away
from a big city, they are less vulnerable, or if they are a small
company, no hacker would go after them.
"It
is a common misconception that virus protection is enough, but
(companies need) much more than that, and ignorance is bliss," said
Gregg Tushaus, president and chief executive officer of Wauwatosa-based
Tushaus Computer Services Inc. Businesses need to adopt multiple
layers of security to protect themselves from both the casual and
experienced hacker, IT industry experts say. Small businesses tend to
purchase wireless routers to connect employee laptops in the office or
enable employees to work off-site, without purchasing additional
security measures. Some businesses believe a router that comes with a
firewall will suffice, Lane said.
A
firewall is a helpful tool, but it acts more like a fence that hackers
can try to gain access through by sending multiple worms and viruses
toward it, Lane said. "What has happened with big companies is that the
firewall acts as a perimeter," Lane said. "There have been a lot of
attacks over time developed by bad guys that realize (the perimeters)
are like big castle walls in the company. so they shoot huge flaming
arrows at (the perimeter). They may shoot 100 arrows that are blocked,
but if one gets inside the castle wall and the building roofs are made
of straw, the whole place will burn down."
Multiple
layers of security, including intrusion detection and spam and spyware
filtering systems, provide more protection than just the firewall. That
way, the flaming arrows might cause a small loss in productivity, but
the contents inside the castle, or computer system and server, will not
burn, IT industry experts say. At a minimum, business owners who have a
limited budget for security measures should at least implement virus
protection, software firewalls and a content filtering system, Lane
said.
Firewalls
cannot protect against fraudulent e-mails and advertisements, so
employees should be trained to recognize and avoid responding to them.
By not implementing security measures, companies take a calculated risk
that can cost more to be reactive than to be proactive, Tushaus
said. Unfortunately, a business owner will not see or appreciate a
return on investment for a security infrastructure until something
happens, Chandra said.
"We
are finding now that in the past, the bad guys were a lot like
electronic graffiti writers and would confuse computer systems and
owners. We wondered why they were writing these viruses and not getting
money for it because it looks like it takes a lot of time and they
cant get any credit for it," Lane said. "Now we are finding that
people have moved to be more like electronic pickpockets where they are
trying to get credit card numbers or rip off small businesses."
Part
of the reason that hackers may have turned into electronic pickpockets
is because the information is available, Lane said. More people are
using the Internet as an automated teller machine or giving companies
credit card numbers to keep on file for convenience, he said. Companies
that keep credit card numbers in a computer system are not necessarily
safeguarded against attacks by viruses and hackers, Lane said. Although
security and computer system companies are trying to educate small and
medium-sized business owners about proper security measures that need
to be in place for both the sake of the business and its clients, many
business owners pass up opportunities to educate themselves because
they believe someone is trying to sell them an unnecessary product or
they do not have the time to learn, IT industry experts say.
Both
Symantec and NetSolutions, among many other companies, offer free
education to consumers and businesses, Lane and Chandra said.
"Companies say they cant afford to do it, but really, they cant
afford not to do it," said Keith Gagnon, business technology consultant
for NetSolutions. NetSolutions provides companies with business
consulting, vulnerability scans of computer systems and intrusion
detection and offers clients a variety of security solutions, said
Allen Waters, corporate marketing director for the company.
When
software programs are created and continuously updated, holes in the
programs are inevitable, Chandra said. Each hole in a program causes
users to be vulnerable to problems with the software and susceptible to
hackers. Software providers create "patches" to fix those holes.
NetSolutions currently has a list of 1,500 and 2,000 vulnerabilities
and patches, Chandra said.
"It
is part of our philosophy to manage security," Chandra said. "For
example, Microsoft releases patches for security, and hackers hope
people dont use them. Hackers write programs for those
vulnerabilities." Chandra likened the process of securing a complex
computer system to taking care of a large house. "When a house
starts with four walls, (individuals) know where there are flaws
because they can see them. But for a house that constantly grows, after
15 years it is a mansion and how can one monitor all of the walls?"
Chandra said. "Essentially it becomes bigger than you and it is the
same for security. There are so many leaks, back doors and alleys that
no one has considered."
Microsoft,
for example, announces vulnerabilities it has found on a security Web
site (www.microsoft.com/security) and provides patches for those
vulnerabilities, Waters said. "Education could be a good service
for people. If they receive it and understand it, for little or almost
no effort they can avoid disaster, because it can cost 10 to 100 times
more to fix a problem then to buy security software," Lane said. "Like
most things in life, an ounce of prevention is a pound of cure."
Myth Busters:
The
common misconceptions that business owners have about security can
become a deadly threat to a business. NetSolutions busts some of the
more common myths its clients have believed in the past.
Wireless Myths:
"
I dont have a wireless network: It may be true that a business owner
has not installed a wireless network but owners need to be sure their
employees have not plugged in a wireless access point, leaving a
company network vulnerable.
"
Wireless network is plug and play: When wireless networks are
installed, IT professionals change default settings and secure the
network.
" Wired equivalent privacy (WEP) will keep me secure:
It
is well known and documented that WEP is not secure and if employed,
business owners increase the risk of compromising their network
security.
"
My business is too inconsequential to be hacked: This is simply not
true. According to statistics from FBI/CERT, hackers dont discriminate
everyone is a potential target.
" I am secure: Business owners may say this without knowing the last time a system security audit was run on their network.
Wired Network Myths:
"
I dont go on the Internet: Users do not have to be on the Internet to
get infected with a virus. Networks can become infected via corrupt
disks, files and other means.
"
It doesnt matter if everyone in the office gets administrative
privileges: Business owners dramatically increase the risk of network
compromise if everyone on the network is an administrator.
"
Windows 98 is just as good for our business needs: From a security
standpoint, it is well documented that Microsoft did not have security
in mind while designing the 98 operating system. Business owners
increase the risk of security breach and compromise valuable data if
they are still using Windows 98.
" A firewall will keep me secure: A firewall is only as good as its configuration and is only one aspect of securing a network.
"
Microsoft patches will wreak havoc on my existing network: Business
owners are advised to back up their systems prior to installing the
latest patches, but if the latest patches arent downloaded, business
owners risk serious damage to their network.
