How Small Business Owners Can Guard Against Online Security ThreatsThe question: As a small-business owner, how can I protect my business from looming online security threats?

The entrepreneurial adventure often starts with a single employee running a home-based operation, with no IT staff and little time to stay aware of Internet security threats.

"For the smallest entrepreneurial businesses, the biggest thing they can do is install anti-virus and malware software on all their computers and servers," says Jeff Horne, director of threat research at Broomfield, Colo.-based Internet security software company Webroot. "You would be amazed how many businesspeople put the anti-virus software on their workstations but not on their servers, where file-sharing viruses still have an impact."
