The many gadgets carried around by workers today <A HREF="http://news.zdnet.com/2100-1009_22-5954642.html?tag=zdnn.alert">pose a real security risk</A> to organizations and require action, session attendees at a security conference agreed Tuesday. Smart phones, handheld computers, thumb drives, digital cameras, iPods and other MP3 players can all connect to computers. That's fine when used at home, but when connected to a work PC, the devices can pose a serious risk, said Norm Laudermilch, chief security officer at Trust Digital, a mobile security vendor. Connecting the gadgets to work PCs could lead to a number of unwanted scenarios, Laudermilch said. For example, malicious code that crept onto the device at home could enter the corporate network unseen by the firewall or intrusion detection software, he said. Also, a disgruntled employee could copy confidential information to the device and walk out with it. Classified information on a mobile device could be a business risk even when used by loyal workers, when their gadget is lost or stolen, for example.
