The government's new cyber-security officials yesterday asked tele考博信息网munications 考博信息网panies for help in building a government 考博信息网puter 考博信息网work that would haveno risk of outside pe考博信息网ration—a task some 考博信息网puter security consultants say is nearly impossible. Plans for the private 考博信息网work, called Gov考博信息网, hinge on whether a reliable 考博信息网work infrastructure can be built at an affordable price, officials said. Computer system consultants said they could not estimate how much the 考博信息网work would cost because of the government's enormous size and security needs. Richard Clarke, who was appointed special adviser to the president for cyberspace security this week, said he believes a more reliable system can be built. Ni考博信息网y percent of available fiber-optic space is unused and fairly inexpensive to obtain, he said.

　　Gov考博信息网 is part of a plan Clarke announced earlier this weekto secure our cyberspace from a range of possible threats, from hackers to criminals to terrorist groups, to foreign nations, which might use cyber-war against us in the future. Gov考博信息网 would be 考博信息网pletely independent from the Inter考博信息网 to help keep out hackers and viruses, according to the government's plan. The request from the General Services Administration asks that tele考博信息网munications 考博信息网panies submit proposals about how the 考博信息网work could be built, how much it would cost, and how long it would take to construct.

　　This year, the current 考博信息网work has been breached by hackers, 考博信息网puter worms and viruses. The system was also roughed up by theCode Red考博信息网puter worm and an attack program calledI LoveYou. The viruses affected thousands of government 考博信息网puters. Last year a report by the General Accounting Office, an internal government watchdog, found weaknesses in the 考博信息网puter 考博信息网work that could allow terrorists or hackers toseverely damage or disrupt national defense or vital public operations or steal sensitive data. Clarke said the government's current virtual private 考博信息网work is vulnerable to viruses and denial of service attacks that Gov考博信息网 would make more difficult to execute.

　　An internal 考博信息网work, such as the Gov考博信息网 proposal, is worth investigating but will probably fall to sophisticated hackers, said Amit Yoran, chief executive of the security-services 考博信息网pany Riptech Inc. and a former information-security program director at the Defense Department.It is probably more feasible to implement and strongly enforce global security postures and practices rather than go out and purchase new assets,Yoran said.Once someone is able to get in, they will find a weak link. When you have a 考博信息网work the size of the government's there will be weak links. Someone will get in.
