Problem: Electronic theft by foreign and industrial spies and disgruntled employees is costing U.S. companies billions and eroding their international competitive advantage. That was the message delivered by government and private security experts at an all-day conference on corporate electronic espionage. "Hostile and even friendly nations routinely steal information from U.S. companies and share it with their own companies," said Noel D. Matchett, a former staffer at the federal National Security Agency and now president of Information Security Inc., Silver Spring, Md. It "may well be" that theft of business data is "as serious a strategic threat to national security" as it is a threat to the survival of victimized U.S. firms, said Michelle Van Cleave, the White House's assistant director for National Security Affairs. The conference was jointly sponsored by the New York Institute of Technology School of Management and the Armed Forces Communications and Electronics Association, a joint industry-government trade group. Any secret can be pirated, the experts said, if it is transmitted over the air. Even rank amateurs can do it if they spend a few thousand dollars for a commercially available microwave receiver with amplifier and a VCR recorder. They need only position themselves near a company's satellite dish and wait. "You can have a dozen competitors stealing your secrets at the same time," Mr. Matchett said, adding : "It's a pretty good bet they won't get caught." The only way to catch an electronic thief, he said, is to set him up with erroneous information. <sep>Where do amateurs need to position themselves to pirate a secret transmitted over the air?<sep>Institute of Technology in New York
Solution: No
