THE RISK FACTOR
Are you at risk? If your vital information is, then so
are you. While you're struggling to make sales or generate Web site
traffic, managing risks to protect vital information is probably the
furthest thing from your mind. None-the-less, as times become more
perilous, risk management is an essential part of the on-line presence.
Myths, hysteria, hyperbole, and misunderstandings abound
about information security on the Internet. Anyone with a Web
presence is being bombarded almost daily with new information
about network security problems and viruses. Acquiring network
providers are on merchant's backs about the new CISP security
requirements. And, everyone is wondering if the next intrusion
will bring down the entire Internet.
OVERVIEW
This is the first of a four part article that will attempt to define
some of the issues of information security, provide perspective, and
offer practical insights about what can be done. It is especially
directed to the small to medium sized merchant and the risks of
conducting credit card transactions through the on-line store. However,
just having a privacy policy implies that you save vital information
and need to manage the risks. Parts 2 and 3 will get into details for
protecting information, including design considerations; part 4 will
summarize the articles and expose a few of the myths.
According to the Gartner Group, 50 percent of small and mid-sized
organizations that manage their own network security and use the
Internet for more than e-mail will be attacked via the Internet by
2003. By 2004, the other 50 percent will have spent more than 20
billion dollars to keep their systems from being attacked.
Put your 20 billion away. This article will not address in any
depth the issues of network security, routers, firewalls, and
intrusion detection systems. It's assumed here that your web site
is hosted by a service provider or that you have your own IT network
staff and that they are looking out for you in this regard.
RISK MANAGEMENT
For anyone storing vital information, some of the risks are
unauthorized copying or downloading of data, unauthorized disclosure,
unauthorized transactions, data destruction, and data alteration.
The objective of risk management is to provide for information
confidentiality and integrity while maintaining availability.
Confidentiality requires a "need to know". Integrity requires
protecting the data from intentional or accidental changes.
Availability requires making the data accessible to authorized
users, but only when, where, and as needed.
No system is 100% secure and the cost of providing security will
rise exponentially as risk approaches zero. Hence, risk management is
required to determine your vulnerabilities and to provide a plan to
begin fixing the areas of greatest exposure.
RISK SOURCES
Security breaches can only come from inside or outside of an
organization and can be unintended or hacker initiated. This
sounds trivial, but consider that an inside breach can come about
through social engineering from an outside hacker. Social engineering
is the process where-by an outsider persuades an insider to take
action and/or disclose information that is not authorized to the
outsider.
Consider this: You have a call center that responds to on-line
store enquiries. You get a call from a customer who says, "This
is Jake Gonnagetcha. The last time I ordered from you I used my
Visa card #4111111111111111. I never know if the card uses my
shipping location or mailing address, but whichever it was, it
worked last time. I want to order again. Can you please tell me
which address I used before?"
