A small group of Internet security specialists gathered in Singapore to start up a global system to make e-mail and e-commerce more secure, end the rapid growth of passwords and raise the bar significantly for Internet fraud, spies and troublemakers.
The Singapore event included an elaborate technical ceremony to create and then securely store numerical keys that will be kept in three hardened data centers there, in Zurich and in San Jose, Calif. The keys and data centers are working parts of a technology known as Secure DNS, or DNSSEC. DNS refers to the Domain Name System, which is a directory that connects names to numerical Internet addresses. Preliminary work on the security system had been going on for more than a year, but this was the first time the system went into operation, even though it is not quite complete.
The three centers are fortresses made up of five layers of physical, electronic and cryptographic security, making it virtually impossible to damage the system. Four layers are active now. The fifth, a physical barrier, is being built inside the data center.
The technology is viewed by many computer security specialists as a ray of hope amid the recent cascade of data thefts, attacks, disruptions and scandals, including break-ins at Citibank, Sony, Lockheed Martin, RSA Security and elsewhere. It allows users to communicate via the Internet with high confidence that the identity of the person or organization they are communicating with is not being tricked or forged.
Internet engineers like Dan Kaminsky, an independent network security researcher who is one of the engineers involved in the project, want to counteract three major deficiencies in today’s Internet. There is no mechanism for ensuring trust, the quality of software is uneven, and it is difficult to track down bad actors.
One reason for these flaws is that from the 1960s through the 1980s the engineers who designed the network’s underlying technology were concerned about reliable, rather than secure, communications. That is starting to change with the introduction of Secure DNS by governments and other organizations.
The event in Singapore capped a process that began more than a year ago and is expected to be complete after 300 so-called top-level domains have been digitally signed. Before the Singapore event, 70 countries had adopted the technology, and 14 more were added as part of the event. While large countries are generally doing the technical work to include their own domains in the system, the association of Internet security specialists is helping smaller countries and organizations with the process.
It is indicated in Paragraphs 1 and 2 that the global system the Internet security specialists gathered to start up（）
A. is still on the drawing board
B. can put an end to Internet fraud
C. has won specialists much acclaim
D. has multi-advantages over previous ones
参考答案：D
解析：
[试题类型] 推理引申题。
[解题思路] 根据题干关键词Paragraphs 1 and 2可定位至文章第一、二段。文章首段指出，互联网安全专家集会新加坡的目的是启动一个新的全球性网络安全系统。第二段指出该安全系统的目的：使电邮与电子商务更安全，终止密码暴增，极大地增加发生欺诈、间谍活动以及制造麻烦的难度(make e-mail and e-commerce more secure...)。由此可知，新的网络安全系统可以解决互联网安全方面的一系列问题，故推断原来的互联网安全系统并没有解决这些问题，所以与以前的系统相比，新系统具有很多优势，故选项[D]正确。
[干扰排除] 第二段最后一句指出，该安全系统的准备工作已经进行了一年多，在新加坡集会上首次投入使用(Preliminary work on the security...this was the first time the system went into operation)，由此可判断该系统现在已经开始应用了。选项[A]意为“还在筹划阶段”，显然与文意不符，可排除。第一段提到启动新安全系统的目的之一是极大地增加网络欺诈的难度(raise the bar for Internet fraud)，但并没有说能将其完全终结(put an end to)，故选项[B]“终结网络欺诈”与原文不符。本文前两段提及了网络安全专家创建新的安全网络的目的以及该网络系统的某些技术细节，并未涉及人们对该系统的评价，选项[C]“为专家们赢得赞誉”并无依据，故排除。
