I have the McAfee security suite loaded and do regular scans so accessing online banking should be protected. Right? Not really, says Jay McLaughlin, CIO of CNL Bank. Accessing online banking from your everyday PC is just asking for trouble, he says. Recognizing that most consumers don't want to buy a separate computer for online banking, CNL is seriously considering making available free Ubuntu bootable 'live CD' discs in its branches and by mail. The discs would boot up Linux, run Firefox and be configured to go directly to CNL's Web site. 'Everything you need to do will be sandboxed within that CD,' he says. That should protect customers from increasingly common drive-by downloads and other vectors for malicious code that may infect and lurk on PCs, waiting to steal the user account names, passwords and challenge questions normally required to access online banking. Who knows? I might decide that I like running Linux for more than just online banking, Mitchell writes.
