网络信息安全英语练习题
网络信息安全英语练习题### Network Information Security Practice Questions1. Understanding Network Security Basics- Question: What is the primary function of a firewall in network security?- Answer: A firewall's primary function is to monitor and control incoming and outgoing network traffic based on predetermined security rules.2. Types of Network Attacks- Question: Differentiate between a DDoS attack and a phishing attack.- Answer: A DDoS (Distributed Denial of Service) attack overwhelms a website or server with a flood of traffic, making it inaccessible. A phishing attack, on the other hand, involves tricking individuals into revealing sensitive information, such as passwords or credit card numbers, through deceptive emails or websites.3. Cryptography- Question: Explain the difference between symmetric and asymmetric encryption.- Answer: Symmetric encryption uses the same key for both encryption and decryption, making it faster but requiring secure key distribution. Asymmetric encryption uses a pair of keys, a public key for encryption and a private key for decryption, which enhances security but is computationallyslower.4. Secure Communication Protocols- Question: What is SSL/TLS and why is it important for secure communication?- Answer: SSL/TLS (Secure Sockets Layer/Transport Layer Security) is a protocol used to provide secure communication over the internet. It is important because it encrypts data being transmitted, ensuring that it cannot be intercepted and read by unauthorized parties.5. Vulnerability Management- Question: How can organizations manage and mitigate software vulnerabilities?- Answer: Organizations can manage and mitigate software vulnerabilities by regularly updating and patching software, conducting vulnerability assessments, and implementing a strong patch management policy.6. Network Security Policies- Question: What are the key components of a network security policy?- Answer: Key components of a network security policy include access control, password policies, network segmentation, incident response plan, and user education on security practices.7. Wireless Security- Question: What is WPA2 and why is it preferred over WPA for wireless security?- Answer: WPA2 (Wi-Fi Protected Access II) is a securityprotocol for wireless networks that provides stronger encryption and is more secure than WPA. It is preferred dueto its use of the Advanced Encryption Standard (AES), whichis more resistant to hacking attempts.8. Intrusion Detection Systems (IDS)- Question: What is the role of an IDS in network security? - Answer: An IDS monitors network traffic for suspicious activity or policy violations. It can detect and alert administrators to potential intrusions or attacks, allowingfor a timely response to mitigate threats.9. Social Engineering- Question: How can social engineering attacks be prevented?- Answer: Social engineering attacks can be prevented by educating employees about the tactics used in such attacks, implementing strict security policies, and encouraging a culture of skepticism towards unsolicited communications.10. Incident Response- Question: What steps should be taken when a security incident is detected?- Answer: Upon detecting a security incident, stepsshould include isolating the affected system, collecting evidence, analyzing the incident, eradicating the threat, restoring affected systems, and reviewing the incident to improve security measures.11. Data Protection- Question: What measures can be taken to protectsensitive data?- Answer: Measures to protect sensitive data include data encryption, access controls, regular backups, and secure data disposal practices.12. Compliance and Regulations- Question: Why is compliance with data protection regulations important?- Answer: Compliance with data protection regulations is important to protect the privacy of individuals, maintain trust with customers, and avoid legal penalties and reputational damage.Remember, these practice questions are designed to test your understanding of network information security concepts and practices. It is essential to stay updated with the latest security trends and technologies to effectively protect your networks and data.。

一、阅读理解First aid is the kind of medical care given to a victim of an accident or sudden sickness before trained medical help can arrive. First aid techniques often are simple. They can be taught to people of all ages. And learning themis important. Knowing how to treat someone in an emergency can mean the difference between life and death.Thousands of persons die each year after eating or drinking poison substances. Experts say most accidental poisonings happen in or near the home. And most are caused by substances we commonly use at home: medical supplies, insect poisons or cleaning fluids. There are several common signs of poisoning: a sudden feeling of pain or sickness, burns in the area of the mouth, or an unusual smell coming from a person's mouth.Health experts generally advise poison victims to drink water or milk. But never give liquids to someone who is not awake or to those having a violent reaction to the poison. Next, seek help from trained medical experts. Save material expelled from the mouth for doctors to examine. Save the container of the suspected poison to answer questions the doctors may have. The container also may describe a substance that stops the poison's effects. Use this substance without delay.The American Red Cross says all homes should have at least three substances to deal with poisoning. One, syrup (糖浆) of ipecac, is a fluid that helps the body expel material from the stomach. Another, activated charcoal (木炭), lessens the danger of poisons. The other material, Epsom salts, helps to speed the release of body wastes. All three should be used only on the advice of a medical expert.1、The phrase "medical supplies" in Paragraph 2 can be replaced by______.A、medicinesB、medical instrumentC、medical deviceD、medical service参考答案:A解析:空空空空空空空空空2、Which of the following statements is NOT true?A、First aid is the medical care given to a victim of an accident or sudden sickness.B、First aid skills often are simple and can be taught to teenagers.C、Syrup of ipecac is a kind of medicine to empty the stomache.D、Health experts generally advise that we should never give liquids to poison victims.参考答案:D解析:3、What is the main purpose of the passage?A、Tell people how to deal with poison.B、Tell people that first aid is essential.C、Tell people how to deal with accidental poisoning.D、Tell people that they can use three substances to deal with poisoning.参考答案:C解析:4、Which of the following is TRUE of a poison victim?A、He will die without first aid.B、He should always drink water or milk.C、He should eat any recommended substances.D、He should be given first aid or resort to medical experts.参考答案:D解析:5、The author states all the following EXCEPT that ______.A、there are thousands of poison victims each yearB、knowing how to treat someone in an emergency is a vital questionC、health experts advise poison victims not to vomit if they were poisoned by a petroleum productD、There are several common signs of poisoning such as a sudden feeling of pain or sickness, or an unusual smell coming from a person's mouth.参考答案:C解析:There’s a great story about an old Finnish woman who, without quite realizing it, was using her cell-phone to access the Internet and track her ci ty’s public transit system. When asked why she used the wireless Internet so frequently, she replied, “What are you talking about? I don’t know anything about this wireless Internet stuff. I just know the bus is here.”Regardless of whether you want to admit it, a lot of us are like that old Finnish woman. When it comes to new mobile applications, many of us do not realize the capability and power that we hold, literally, in our hands.What we are looking at today is the mobile Internet in its infancy. Now that using the Internet from home or work has saturated much of society, the next logical step is to be able to use the Net when you are far away from your desktop or laptop. Speech recognition is one way to do this, and there are a number of services, col lectively called the “voice Web”, that will make this possible. All you do is to use a phone or wireless device to call a phone number, and speak commands to an intuitive system. It will then give you the information you’re seeking, using either a synthesi zed voice or an audio file.In the United States and Europe, the hot technology for wireless devices is called WAP (Wireless Application Protocol), which is being considered as the world standard. WAP is supported by major phone companies including Nokia, Motorola and Ericsson, and is simply a means of transmitting information, much like HTML which is a means of communicating on the Internet.Currently, wireless Internet connections may give you news, sports scores, stock quotes, and the weather if you’re lucky. But if you’ve ever used this technology, you know it’s slow, costly and doesn’t seem worth the time and effort, if it works at all. All of this technology points to easier living. Perhaps you’ll need to find a restaurant for an occasional businessme eting. You’ll press a button on your mobile phone, and access the Internet to pull up a list of great restaurants in your immediate area. You’ll hit another button, say a few words into the handset and you’ve got a reservation for four.6、The author uses the story of an old Finnish woman to indicate that __________.A、she is ignorant of some common knowledgeB、public transit system contains the accessory to InternetC、many people are unaware of the function of the new appliances being usedD、the Internet is experiencing rapid growth参考答案:C解析:7、The word “saturate” (Para. 3) most probably means _________.A、stateB、utilizeC、despiseD、fill参考答案:D解析:8、According to the text, WAP is a __________.A、technology standard set by major phone companiesB、substitution of HTML which can be applied on the InternetC、means of exchanging informationD、software application for transmitting voice over telephone lines参考答案:C解析:9、We can infer from the passage that the mobile Internet is different from the previous Internet in that the former __________.A、can be accessed by desktop computersB、has no need for wire appliancesC、can be used to book a table in a restaurantD、is equipped with speech recognition systems参考答案:B解析:10、What is the attitude of the author towards the future of mobile Internet?A、IndifferentB、NeutralC、OptimisticD、Pessimistic参考答案:C解析:二、词汇与语法11、The two friends shared a _______ interest in stamp collecting.A、commonB、generalC、popularD、usual参考答案:A解析:12、_______ the fact that his initial experiments had failed, Prof. White persisted in his research.A、Because ofB、As toC、In spite ofD、In view of参考答案:C解析:13、Only after he has acquired considerable facility in speaking _______ to learn to read and write.A、he beganB、will he beginC、did he beginD、must he begin参考答案:B解析:14、Not only _______ our money, but we were also in danger of losing our lives.A、we lostB、lost weC、we did loseD、did we lose参考答案:D解析:15、That poorly dressed old man felt quite ________ at such a big party attended by many important figures.A、in the wayB、out of the wayC、out of placeD、in place参考答案:C解析:根据句意，此处应该选C，大概的句意是“…老人在…宴会上感到不自在”。

Since the dawn of human ingenuity (独创性), people have devised greater and greater tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion (强制) has resulted in attempts to make robots, machines with human capabilities. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close.As a result, the modern world is increasingly full of intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum (忙碌) to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robot drivers. And thanks to the continual miniaturization (小型化) of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with perfect accuracy—far greater precision than highly skilled physicians can achieve with their hands alone.But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves-goals that pose a real challenge. "While we know how to tell a robot to handle a specific error," says Dave Lavery, manager of a program at NASA, "we can't yet give a robot enough 'common sense' to reliably interact with a dynamic world."Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor (晶体管) circuits might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.1.Human ingenuity was initially demonstrated in ________.A. the use of machines to produce science fictionB. the wide use of machines in manufacturing industryC. the invention of tools for difficult and dangerous workD. the clever tackling of dangerous and boring work2.The word "gizmos" (paragraph 2) most probably means________.A. programsB. expertsC. devicesD. creatures3.According to the text, what is beyond man's ability now is todesign a robot that can ________.A. fulfill delicate tasks like performing brain surgeryB. interact with human beings orallyC. have a little common senseD. respond independently to a changing world4.What does the author think?A. Robots will always require supervision.B. People have both successes and failures with robots.C. The making of robots will always meet mixed successes.D. Robots and people should never be mixed.5.What made people optimistic about robots?A. Transistor circuits.B. The 60s and 70s.C. Researchers.D. The human brain.Questions 6 to 10 are based on the same passage or dialog. Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $26 a barrel, up from less than $10 last December. This near-tripling (几乎三倍) of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled (四倍的), and 1979-1980, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economicdecline. So where are the headlines warning of gloom (沮丧) and doom (厄运) this time?Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. Rich economies are less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25-0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil-importing emerging economies—to which heavy industry has shifted—have become more energy-intensive, and so could be more seriously squeezed.One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general product-price inflation and global excess demand. A sizable portion of the world is only just emerging from economic decline.6.What does the author describe as frightening?A. The 1973 oil shock.B. Global economic decline.C. The gloom and doom of this time.D. OPEC supply-cuts.7.What are newspapers having people believe?A. The rise in oil is going to cause serious problems.B. The economy is going to get better.C. Oil prices are going to triple.D. Energy conservation is necessary.8.What has new technology lead to?A. Double-digit inflation.B. Reduced oil dependency.C. Steel production.D. Energy conservation.9.Why does the author tell us "not to lose sleep"?A. We will need energy from sleep.B. Worrying will not help.C. We need not worry.D. People will be seriously squeezed in the future.10.From the text we can see that the writer seems ________.A. optimisticB. sensitiveC. sadD. scared。
