Engineers within Symantec Corp.’s research and development organization have built a new database security appliance that could eventually lead the Cupertino, Calif. company into the database security business. The project has been tested by a handful of Symantec customers since September, and the company is expected to decide within the next few months whether to bring it to market.

The unnamed appliance is a preconfigured server that sits on the network and monitors the database traffic, looking for inappropriate queries. “We’re providing Big Brother in a box, if you like, to just keep a gentle eye on people. And if people deviate from their normal patterns, we can flag that,” said Gerry Egan, group product manager with Symantec’s Advanced Concepts Group.

The appliance, which has been under development for several years, monitors network traffic using the same underlying “sniffing” engine as Symantec’s Network Security 7100 Series intrusion prevention appliance.

But the 15 engineers working on the project have also developed their own software, which then analyzes the database queries. The current version of the Symantec appliance does not actually block suspicious queries — it simply monitors and reports on what the database is up to — but that feature is being considered for a future version of the product, Egan said.

“Our product particularly comes into play where there are valid or authorized users of the database who now start to abuse the privilege,” Egan said. The product could be used to detect employee or partner fraud, or to warn database administrators (DBAs) when their applications appear to be acting in a malicious manner.

Symantec is testing prototypes of the product with customers in the health care and financial services industries, as well as with educational and government users, in a trial run that is scheduled to go on through the end of this year. “At that point, it will be up to management whether they would like to build it into a product,” Egan said.

Should that happen, Symantec would be the first major vendor to develop this type of product, analysts say. To date, database security appliances are sold by only a handful of small companies, including Imperva Inc. and Guardium Inc., but enterprise users are becoming increasingly focused on data security and regulation compliance.

“We’re starting to see a little more interest in this area because of all this identity theft,” said John Pescatore, an analyst with research company Gartner Inc.

Imperva’s chief executive officer Shlomo Kramer, whose three-year-old company already sells a similar product, said he is not surprised to see Symantec looking into this market. During the past few quarters, demand for this type of product has accelerated, spurred by laws such as the Sarbanes-Oxley Act and the Health Insurance Portability and Accountability Act in the U.S., he said.
