19、ter Ethics.Lecture 1 Computer ethics 8 Good morning. Did anyone hear the news about the teenager in New York who hacked into a banks database and stole about 30,000 credit card numbers over the week end? Hacking is related to computer ethics. Computer ethics deals with the proper use of information
20、technology, such as computers and the Internet. By proper use, I mean socially responsible use. Well first talk about what ethical behavior is and then how this applies to computer use. Ethics is about right and wrong or it deals with moral judgment, with what is acceptable or unacceptable to do. No
21、w we learn ideas about what is right and wrong from our families, our friends, and from the culture we live in. Because of differences in our backgrounds, we may not always agree on what is right and wrong. However, for our discussion today, I will define for you what I mean by an ethical action. An
22、 ethical action is something someone does that benefits someone and doesnt hurt anyone. So, for example, if you see a man drop some money and you pick the money up and give it to him, this is an ethical action. On the other hand, if you pick up the money and dont give it back to the man, this benefi
23、ts you, but hurts the man. This is not an ethical action. Now what about computers? What are the ethical boundaries for using computers and Internet? Most people agree that it is wrong to steal from a store. Would they also say its wrong to copy music files from the Internet? Or, to take another exa
24、mple, most people agree that it is wrong to open an envelope and read a letter to someone else. Would they also say its wrong to read someone elses email?In the past decade or so, many more people have started using computers and the Internet, so these issues have become important. In 1992, the Comp
25、uter Ethics Institute was founded in the United States. This is a research, education, and policy study group whose goal is to increase awareness of the ethical issues that are likely to come up as technology develops. One concept the Computer Ethics Institute has developed is the Ten Commandments o
26、f Computer Ethics. These rules are important guidelines the Institute thinks all computer users should follow. Now some of you may be familiar with the Ten Commandments from the Bible, like, uh, “Thou shalt not kill.” or “Thou shalt honor thy father and thy mother.” The Ten Commandments of Computer
27、Ethics have been written in the same style of language used in the Ten Commandments from the Bible. For example, they use the phrase “Thou shalt not”, “Thou shalt not” means “dont” or “you shouldnt”.Lets look at each commandment or rule.The first commandment says: Thou shalt not use a computer to ha
28、rm other people. Simple enough, right?Number Two: Thou shalt not interfere with other peoples computer work. I interpret this to mean dont use a computer in any way that will affect or change the work someone else is doing. Dont move or edit someone elses files without telling them. Number Three: Th
29、ou shalt not snoop in other peoples files. To snoop means to try to find out something without another person knowing it. If you look at someone elses files on the computer or read their email, youre snooping. Respect other peoples privacy.Number Four: Thou shalt not use a computer to steal. There a
30、re situations on the Internet in which you have to decide if you are stealing or not, like downloading music files, as I mentioned earlier. Number Five: Thou shalt not use a computer to say things that are untrue. It is up to you to be truthful in your website, in your e-business, and in your email.
31、Number Six: Thou shalt not use software for which you have not paid. In other words, if the software is free on the Internet, its okay to download and use it. However, it is not okay to copy software from a friend, because you didnt pay for it.Number Seven: Thou shalt not use other peoples computer
32、resources without telling them, or without paying them. For example, you shouldnt use someone elses computer, password, or Internet connection without asking them first.Number Eight: Thou shalt not appropriate someone elses ideas. Appropriate means to take words someone else wrote and say theyre you
33、rs. Uh, for example, you have to write a report for school. If you copy a term paper from the Internet and hand it in, youre breaking the rule. Copying even a few sentences off the Internet and presenting them as your own is breaking the rule. Number Nine: The ninth commandment says: Thou shalt thin
34、k about the social consequences of the program you are writing. Now, this applies mostly to computer programmers. Social consequences means how the program youre writing might affect others in society. Could hackers possibly use your program to illegally gain access to a computer system? Skillful ha
35、ckers can hack into banks and into credit card companies; they can alter accounts and steal money. They can also create viruses that can cause billions of dollars of damage worldwide. Number Ten, The tenth commandment says: Thou shalt always use a computer in ways that are respectful of others. For
36、example, sending unfriendly email to someone or about someone or creating websites with negative messages are examples of breaking this rule.OK, the Computer Ethics Institute has sent these guidelines to many large companies and to schools across the United States. However, theres no way to enforce
37、these rules. Nevertheless, they would like to see schools, in particular, utilize these rules to help students develop a strong sense of computer ethics. Well, there are a lot of rules, but they all boil down to a couple of principles: respect and fairness. Respect what belongs to others and use res
38、ources fairly.Now lets go back to ethics. Now increasingly, schools are seeing that students need to be taught computer ethics as part of the school curriculum. Some schools have come up with acceptable-use policies, or rules about what is or isnt OK for students to do regarding computer use. This i
39、s how the Computer Ethics Institute would like to see schools utilizing the rules. Generally, its considered wrong to steal someone elses password or to read some elses email. Its also considered unacceptable in college classes for a student to download a term paper off the Internet and pretend that
40、 he or she wrote it. This is called “plagiarism”, and its a good example of breaking Rule Number Eight. Students are permitted to use the Internet for research, but are instructed to write the information in their own words and to explain where they got the information.Now the ten rules are guidelin
41、es for us to follow. These rules help us to be aware of the ethical uses of technology. Lets stop here for today. Think about these rules this week and well talk about them. And read the next two chapters for next week. Listening: Lecture 21 Its a sophisticated group of politically motivated hackers

45、ed hackers who have emerged in 2011. And theyre pretty scary. You never know when theyre going to attack next, who or what the consequences will be. But interestingly, they have a sense of humor. These guys hacked into Fox News Twitter account to announce President Obamas assassination. Now you can
46、imagine the panic that would have generated in the newsroom at Fox. “What do we do now? Put on a black armband, or crack open the champagne?” (Laughter) And of course, who could escape the irony of a member of Rupert Murdochs News Corp. being a victim of hacking for a change. (Laughter, applause) So
47、metimes you know you turn on the news and you say, “Is there anyone left to hack?” Sony PlayStation Networkdone; the government of Turkeytick, Britains Serious Organized Crime Agencya breeze, the CIAfalling off a log. In fact, a friend of mine from the security industry told me the other day that th
48、ere are two types of companies in the world: those that know theyve been hacked, and those that dont. I mean three companies providing cyber security services to the FBI have been hacked.
