　　Passage Two
　　Questions 57 to 61 are based on the following passage.
　　InfraGard is a grass-roots effort to respond to the need for cooperation and collaboration in countering the threat of cyber crime and terrorism to private businesses and the government. By the end of September, there will be InfraGard chapters in all 50 states, Calloway said. With advice from the FBI, each local chapter will be run by a board of directors that includes members of private industry, the academic community and public agencies. Bands, utilities, and other businesses and government agencies will use a secure Web site to share information about attempts to hack into their computer networks. Members can join the system free. A key feature of the system is a two-pronged method of reporting attacks.
　　A "sanitized" description of a hacking attempt or other incident-one that doesn't reveal the name or information about the victim-can be shared with the other members to spot trends. Then a more detailed description also can be sent to the FBI's computer crimes unit to interfere if there are grounds for an investigation. Cyber crime has jumped in recent years across the nation, particularly in hotbeds of financial commerce and technology like Charlotte. "Ten years ago, all you needed to protect yourself was a safe, a fence and security officers," said Chris Swecker, who is in charge of the FBI's Charlotte office. "Now any business with a modem is subject to attack." FBI agents investigate computer hacking that disrupted popular Web sites including Amazon. com, CNN and Yahoo!
　　several North Carolina victims have been identified this year. The investigation has also identified computer systems in North Carolina used by hackers to commit such attacks. Prosecutions of hackers have been hampered by the reluctance of companies to report security intrusions for fear of bad publicity and lost business. Meanwhile, too many corporations have made it too easy for criminals by sacrificing security for speed and accessibility. Jack Wiles, who will lead the local InfraGard chapter's board, said a recent report estimated 97 percent of all cyber crime goes undetected. Wiles, a computer security expert, has a firewall on his personal computer to prevent hackers from getting into his files. "I get at least one report a day that somebody was trying to get into my computer," he said, "the Net is a wonderful place, but it's also a dangerous one."
