Banks face challenge in screening employees

updated 2:34 p.m. ET June 30, 2005

CHARLOTTE, N.C. - When two of the nation’s largest banks were forced to notify thousands of customers that their financial records may have been stolen, there wasn’t a hacker, a missing laptop or a lost box of backup computer tapes to blame.

This time, police believe, customers of Wachovia Corp. and Bank of America Corp. were the victims of bank employees, workers whose jobs at the Charlotte-based banks granted them access to information valuable enough to sell for $10 an account.

Security experts believe it’s that battle against insiders — the theft of Social Security numbers and other sensitive data by those with the authority to access it — that will consume banks and other financial institutions as they fight a recent run of security breaches that doesn’t appear to be waning.

“We’ve got a nasty problem and it keeps getting worse over the past couple of months,” said Peter G. Neumann, a security expert with SRI International in Menlo Park, Calif. “Insiders have always been a concern, it’s just that (institutions) are finally admitting it.”

Security experts like Neumann believe inside jobs have the potential to be far more damaging to consumers than accidental losses of data, or attacks by hackers similar to one disclosed June 17 at Atlanta-based CardSystems Solutions Inc., which exposed 40 million credit and debit card accounts.

And the protections banks use to thwart hackers — firewalls and encryption, for example — have no ability to stop ill-intentioned employees who have authorized access to secure information.

The insider case at Bank of America, Wachovia and two other banks — involving a far smaller number of accounts than the hackers’ assault on CardSystems Solutions — could prove to be far worse for consumers, said Avivah Litan, an analyst with Stamford, Conn.-based Gartner Inc., an information technology research firm.

“It may not be bigger, but that stuff is a lot more dangerous,” Litan said. “These are people who have access to a lot more personal information, so it’s very serious.”

Wachovia and Bank of America were forced to alert more than 100,000 customers in May after police in New Jersey charged nine people, including seven bank workers, in a plot to steal financial records of thousands of bank customers.

“About 70 to 80 percent of the risk is from insiders, although not all of them are as malicious as the case in New Jersey,” said Steve Roop, vice president of marketing at San Francisco-based Vontu, a firm specializing in data loss prevention. “Sometimes it is well meaning but poorly informed workers.”

As might be expected when the subject is security, neither Wachovia nor Bank of America are willing to explain in detail efforts they take to protect sensitive data from employees who want to illegally sell private account information.

“All of our associates must adhere to a code of ethics and to company policy,” said Tara Burke, a spokeswoman for Bank of America. “And our bank associates only have access to the information they need to provide service to our customers.”
