************ February 9, 2000, Dow Jones News Service In Wake Of Attacks, Web Sites Turn To Law Enforcement By PETER LOFTUS NEW YORK -- For all their technological savvy, Internet companies by themselves can't always prevent the kinds of illegal attacks that have shut down several leading Web sites this week. The Web site attacks continued for a third consecutive day Wednesday, temporarily shutting down online properties operated by Ziff-Davis Inc.'s ZDNet unit (ZDZ), E*Trade Group Inc. (EGRP) and Datek Online Brokerage Services. Hackers temporarily shut down sites operated by Yahoo! Inc. (YHOO), EBay Inc. (EBAY), Amazon.com Inc. (AMZN), Buy.com Inc. (BUYX) and Time Warner Inc.'s (TWX) CNN.com on Monday and Tuesday. The Federal Bureau of Investigation is investigating the attacks and has scheduled a news conference for 2 p.m. EST in Washington. Several large Internet companies seem to have escaped the wrath of the hackers so far. America Online Inc. (AOL), Excite@Home Corp. (ATHM), Lycos Inc. (LCOS), About.com Inc. (BOUT), CMGI Inc.'s (CMGI) AltaVista unit and Walt Disney Co.'s Go.com (GO) unit said Wednesday they hadn't been victimized. AltaVista Chief Information Officer David Henke agrees, noting that the very nature of the Internet makes it vulnerable to attacks. The Internet was structured as an open system and in that environment, companies need contingency plans. If the main problem in this week's attacks involved Web sites being overrun by data, then shouldn't these companies simply boost their capacities for handling the data? Henke is skeptical of this approach. "You could boost capacity but at some point it becomes cost-prohibitive," he said. He doesn't think people will turn away from the Internet in flocks, but he says that companies will have to respond to demands that Web services be more stable and reliable.
