Inktomi to check viruses at cache
The company hopes the deal will block a relatively new path that viruses have into corporate networks: Web pages.
"We can assure that any content a user requests from the Web is clean," said Liz Padula, market development manager for the Foster City, Calif., company.
The software will scan any object from a Web site for malicious code before caching that object to Inktomi's Traffic Edge Security Edition server software, which serves pages to employees' browsers and also saves pages for easy recall. By only caching clean content, and not potential viruses, the antivirus software can prevent malicious code from finding its way into a company from a traditionally unmonitored source.
"It is yet another way for viruses to get in," said Steve Trilling, director of Symantec Security Response. "Nimda is a perfect example of something that spread through a Web site mechanism."
While worms spreading via Web sites are relatively rare--far more common are worms that use e-mail and software exploits--many times a worm can bypass a company's protections against the more major vectors by taking to the Web, said Trilling.
"I think you need to consider any potential network connection as a way to transmit viruses," Trilling said.
