[ISN] Local banks beef up security

University Bank's new computer security hardware is only the size of a 
typical DVD player.

But the bank announced last month that it's betting the Promia Raven 
1100 security system will help improve its defense against potential 
hackers with technology previously used only by the U.S. Navy.

Within the system's first day of use, the bank was alerted that hackers 
were trying to enter the system from North Korea, China and Oman, said 
Stephen Ranzini, company president and chairman.

The bank and its parent company, University Bancorp Inc. (Nasdaq: UNIB), 
are housed at the renovated Hoover Mansion on Washtenaw Avenue in Ann 
Arbor. The company employs about 30 people and reported earnings for the 
first nine months of 2007 of $1 million.

"You hear about this stuff all the time, how people overseas are trying 
to break into networks, but where's the proof?'' Ranzini said. "If 
they're going to come after us, they'll go after everyone.''

Other local banks say they are constantly investing in new products as 
hacker threats continue to increase, with many of the banks upgrading 
their systems within the last year. And when it comes to network 
security, smaller banks are using more sophisticated technology - and 
sharing more information with other banks about combating threats - than 
ever before, said Larry Ponemon, founder of the Ponemon Institute, a 
Traverse City-based data protection research group.

"Banks are seeing security not just as a cost of compliance, but also as 
a reputation issue,'' Ponemon said. "If they can have better security 
over data they are protecting, customers might actually flock to those 

Some of the most common threats to bank security are phishing and 
pharming schemes, which involve the use of fake bank e-mails or Web 
sites, and social engineering, which involves digging for information 
about the bank culture online to trick information out of bank 
employees, said Jay Patterson, vice president of information technology 
for United Bancorp Inc., in an e-mail. Ann Arbor's United Bank and Trust 
is part of United Bancorp's organization of banks.

United Bank and Trust has many different layers of security that are 
regularly tested using simulated electronic and social engineering 
attacks. Last year, the bank upgraded its Web content filtering and 
phishing prevention service. In 2007, it made major investments in 
security to respond to direct attacks and was able to minimize the 
damage from those attacks, Patterson said.

"Bank security is a 24 x 7 x 365 initiative,'' Patterson said.

Chelsea State Bank also has invested in a new security system, which 
blacklists IP addresses that try to maliciously break in, said Scott 
Tanner, chief operations officer.

He declined to reveal what brands of systems are in place at the bank, 
but said it's a full-time job monitoring all the layers of security and 
keeping up with new threats.

One of the most reliable and credible ways to keep up is by remaining 
active in a national banking user group that Chelsea State Bank joined 
back in 1985, he said.

"We found out early on we had a lot in common that we had to work on,'' 
including security, Tanner said. "Because banks were from around the 
country, we weren't sitting down with competitors from across the 
street, so we could really lay our cards down.''

For University Bank, investing in the Raven system seemed to be the best 
choice, Ranzini said, because it links the bank to other Raven users. 
That creates a much broader malicious IP address blacklist that keeps 
those addresses from ever being able to guess any of the networks' 
passwords again. It also tracks attacker activity for possible 
prosecution and can alert network administrators to unauthorized 
internal use and computer malfunctions.

"Time is the issue for the bad guys,'' Ranzini said. "All cryptography 
is based on the amount of time it would take to break in. Why give them 
all that time?''

Despite all the efforts that banks are making, Tanner said, it's the 
customers' responsibility to monitor their own banking statements - 
especially since they are available to check almost immediately online.

"No technology in the world can alert us to a problem as effectively as 
the consumer actually looking for it themselves.''
