# }, n( K! }, h) \6 D8 f考研专业课论坛The government's new cyber-security officials yesterday asked telecommunications companies for help in building a government computer network that would haveno risk of outside penetration—a task some computer security consultants say is nearly impossible. Plans for the private network, called Govnet, hinge on whether a reliable network infrastructure can be built at an affordable price, officials said. Computer system consultants said they could not estimate how much the network 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. Ninety percent of available fiber-optic space is unused and fairly inexpensive to obtain, he said.
% ?0 V: I7 f {! @-- 最聚人气内容最全的考研综合互动论坛 Govnet 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. Govnet would be completely independent from the Internet to help keep out hackers and viruses, according to the government's plan. The request from the General Services Administration asks that telecommunications companies submit proposals about how the network could be built, how much it would cost, and how long it would take to construct.
: }1 h8 [+ K+ ]: _ E2 R$ E This year, the current network has been breached by hackers, computer worms and viruses. The system was also roughed up by theCode Redcomputer worm and an attack program calledI LoveYou. The viruses affected thousands of government computers. Last year a report by the General Accounting Office, an internal government watchdog, found weaknesses in the computer network 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 network is vulnerable to viruses and denial of service attacks that Govnet would make more difficult to execute.

An internal network, such as the Govnet proposal, is worth investigating but will probably fall to sophisticated hackers, said Amit Yoran, chief executive of the security-services company 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 network the size of the government's there will be weak links. Someone will get in. 海文考研,海文考研辅导班,2009考研,考研专业课,,万学海文,海天专业课,海文, {% A7 j1 ^9 y6 N* g" i! g. y

政府负责网络安全的新官员昨天要求通信公司帮助建立一个政府计算机网络,这个网络将“不会受到外侵的威胁”——一些计算机安全顾问认为这个任务几乎是无法完成的。这个政府专用网络叫做Govnet,官员们说,能否实现建立这个专门网络的计划取决于一个可靠的网络基础设施能否以合理的价格建立起来。而计算机系统顾问们说,他们无法估算这个网络的预算,因为政府工作规模巨大,安全要求很高。Richard Clarke本周被任命为总统网络空间安全特别顾问,他说他相信可以建立一个更加可靠的系统。他说,90%的可用光纤空间都没派上用场,并且费用不大。海文考研,海文考研辅导班,2009考研,考研专业课,,万学海文,海天专业课,海文1 }1 }* d4 f5 f, X% ^
本周早些时候Clarke宣布了一项计划,旨在“确保网络安全,防止可能产生的一系列威胁——如来自于黑客、罪犯、恐怖组织或国外的威胁,防止这些势力将来向我们发动网络战”。Govnet是这个计划的一部分。根据这项政府计划,Govnet将完全脱离因特网,以防止黑客和病毒的袭击。服务总局要求通信公司提交建议,说明这个网络如何建立、需要多少费用、需要多长的建设时间。海文考研,海文考研辅导班,2009考研,考研专业课,,万学海文,海天专业课,海文, m! t( t4 L- K y
