<..Microsoft Corp., in fact, is warning Windows 95 users that the simple act of sharing files with a printer can open your PC and all your personal and business files to prying eyes if the PC is connected to a cable TV network ....> Though you did reference the whole article, you seemed to stop one line short of completing the above consideration: "..Microsoft's recommendation is: shut off the share option on the PC. " Other saliet article points which give more of a balance to the addressed security issue: ".. He is calling on upstart Assured Digital, Inc., of Littleton, Mass., which specializes in cable network security. Assured Digital makes cable modems that encrypt traffic using DES and triple DES and hashing technologies. While Borden is working out security on his own, cable providers, sensitive to their customers' vulnerability, also are taking steps to plug leaks. MediaOne Group, the cable company owned by US WEST, Inc., puts filters on its cable modems [fwiw - so does COX]. The filters make customers' PCs invisible to each other across the cable network, according to Kip Compton, director of Internet systems and services for MediaOne. Additionally, MediaOne offers most customers a filter {also available from COX, and I'm sure soon from most others as well]. As a default, the filter blocks all outside access but the customer can disable the filter to allow access to the PC or only certain files, Compton said. That would let customers remotely reach work from their home PCs. Access from the cable network also can be password-protected. Data security on the cable network can be reinforced by tunneling technology that encrypts IP packets and encapsulates them for transport across IP networks. (sounds like the emerging VPN approach) The encryption that secures IP traffic from client to host will pose as much trouble for hackers on the cable network as it would for hackers on the Internet, according to Digital Equipment Corp. Digital is giving its work-at-home employees cable access over the Internet to corporate LANs, protected by AltaVista Tunnel 97 software. ..." Considered more fully, the concern seems more superficial, and certainly addressable. Steve
