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.
We can infer from the last paragraph that（）
A. the Net security system will catch on soon
B. engineers prefer to wait and see how things go
C. actions are taken to utilize the security system
D. more countries are supposed to invest in the system
参考答案：C
解析：
[试题类型] 推理引申题。
[解题思路] 根据本题题干中的last paragraph定位至末段。该段第二句指出，在新加坡集会之前已经有70个国家采用了这一技术，又有14个国家成为新加坡集会的新成员(70countries had adopted the technology...)。最后一句也指出“一般来说，大国正在做技术工作，将自己的域名加入该系统中，而互联网安全专家小组正在帮助较小的国家和机构完成这项工作”，由此可判断，各方正在积极采取行动应用该安全系统。选项[C]表述的内容与原文吻合，故为正确选项。
[干扰排除] 选项[A]中的catch on意为“流行”，原文中只是提到该系统目前的进展如何，何时能够完成等情况，并没有对该系统的应用前景做出预测，故排除该选项。选项[B]与末句信息不符，该句提到互联网安全专家们正在帮助较小的国家和机构推进该安全系统的建没(the consortium of Internet security specialists is helping...)，故他们并不是在观望，而是有积极的行动，故排除该项。选项[D]中的“投资该系统”(invest in the system)属无中生有，文中并没有投资网络安全系统的相关内容，故可排除该选项。
