Stop these employees from leaking your corporate data

You might know how to secure your network devices and data centers to keep
your corporate intelligence safe. But do you know how to teach your employees
how to guard against attacks -- not generically, but based on the work they
do? Experts suggest that a well-constructed security plan involves customized
training by job function. You need to tell your HR people to manage personnel
files that might reside in multiple locations, your facilities crew to watch
out for people entering the building with fake IDs and your salespeople to guard
access to the company's CRM system.

Trusting an employee with access to mission-critical or sensitive systems is
a risky but unavoidable gamble. Let's face it: People are wild cards. In fact,
let's take the gambling analogy a step further. Just as casinos thwart cheaters
at every table or station on their floors, so, too, can IT officials thwart
breaches by customizing security plans for individual employees in every zone
of their companies.

In fact, casino practices can be translated to the corporate IT world to create
at a common-sense list of do's and don'ts for redoubling security based on who
does what job. The lessons we learn from craps pits and blackjack tables reveal
that it's never wise to entrust your business's most valuable or vulnerable
assets to a single employee. Instead, compartmentalize access whenever possible,
and never hesitate to look over employees' shoulders.

Above all, follow the golden rule of a casino: Gauge your level of risk and
develop airtight audit trails, urges Bruce Schneier, a security expert in Mountain
View, Calif., who has written several books on computer and network security,
including Applied Cryptography (Wiley, 1996). Schneier often uses the casino
metaphor to drive home important points surrounding individualized security.
"If you look at a casino floor, you will notice immediately that people
are watching people," he says. "That's because a lot of cash is moving,
and it's moving very quickly."

Just as edgy casino managers constantly size up everyone on the floor as potential
security threats, so must corporate IT security leaders size up every employee.
"People are the weakest link in security. They always have been, and you
will never change that," Schneier says. "But the reality is that you've
got to deal with people, and people are going to make mistakes."

Security isn't the responsibility of a single security manager or even a security
department. Just as quality was understood in the 1980s to be the responsibility
of everyone in an organization, so, too, is security everyone's responsibility.
