- 34. 4-34 THE FIRST LINEOF DEFENSE - PEOPLE
- 35. 4-35 THE SECOND LINEOF DEFENSE TECHNOLOGY • There are three primary information technology security areas 1. Authentication and authorization 2. Prevention and resistance 3. Detection and response
- 36. 4-36 Authentication and Authorization • Authentication– a method for confirming users’ identities • Authorization – the process of giving someone permission to do or have something • The most secure type of authentication involves: 1. Something the user knows such as a user ID and password 2. Something the user has such as a smart card or token 3. Something that is part of the user such as a fingerprint or voice signature
- 37. 4-37 Something the UserKnows Such As a User ID and Password • This is the most common way to identify individual users and typically contains a user ID and a password • This is also the most ineffective form of authentication • Over 50 percent of help-desk calls are password related
- 38. 4-38 Something the UserKnows Such As a User ID and Password • Identity theft – the forging of someone’s identity for the purpose of fraud • Phishing – a technique to gain personal information for the purpose of identity theft, usually by means of fraudulent email
- 39. 4-39 Something the UserKnows Such As a User ID and Password
- 40. 4-40 Something the UserKnows Such As a User ID and Password • Smart cards and tokens are more effective than a user ID and a password – Tokens – small electronic devices that change user passwords automatically – Smart card – a device that is around the same size as a credit card, containing embedded technologies that can store information and small amounts of software to perform some limited processing
- 41. 4-41 Something That IsPart Of The User Such As a Fingerprint or Voice Signature • This is by far the best and most effective way to manage authentication – Biometrics – the identification of a user based on a physical characteristic, such as a fingerprint, iris, face, voice, or handwriting • Unfortunately, this method can be costly and intrusive
- 42. 4-42 Prevention and Resistance • Downtimecan cost an organization anywhere from $100 to $1 million per hour • Technologies available to help prevent and build resistance to attacks include: 1. Content filtering 2. Encryption 3. Firewalls
- 43. 4-43 Content Filtering • Organizations canuse content filtering technologies to filter e-mail and prevent emails containing sensitive information from transmitting and stop spam and viruses from spreading. – – – Content filtering – occurs when organizations use software that filters content to prevent the transmission of unauthorized information Spam – a form of unsolicited e-mail Corporate losses caused by Spam
- 44. 4-44 Encryption • If there isan information security breach and the information was encrypted, the person stealing the information would be unable to read it – Encryption – scrambles information into an alternative form that requires a key or password to decrypt the information – Public key encryption (PKE) – an encryption system that uses two keys: a public key for everyone and a private key for the recipient
- 45.
- 46. 4-46 Firewalls • One of themost common defenses for preventing a security breach is a firewall – Firewall – hardware and/or software that guards a private network by analyzing the information leaving and entering the network
- 47. 4-47 Firewalls • Sample firewall architectureconnecting systems located in Chicago, New York, and Boston
- 48. 4-48 Detection and Response • Ifprevention and resistance strategies fail and there is a security breach, an organization can use detection and response technologies to mitigate the damage • Antivirus software is the most common type of detection and response technology
- 49. 4-49 Detection and Response • Hacker- people very knowledgeable about computers who use their knowledge to invade other people’s computers – – – – – – White-hat hacker Black-hat hacker Hactivist Script kiddies or script bunnies Cracker Cyberterrorist

Editor's Notes
- #3 Share any examples of unethical behavior you have recently observed? Share any security issues you have recently encountered? Many students have already experienced identity theft, stolen items, and phishing scams. Asking students to share their stories gets the class excited and involved with ethics and security
- #4 CLASSROOM OPENER NOT-SO-GREAT BUSINESS DECISIONS – Scrushy Faces 30 Years in Prison Richard Scrushy, former chief executive of HealthSouth, was convicted of bribing Don Siegelman, former governor of Alabama, for a seat on the state's hospital regulatory board, which oversaw some of his company's facilities. The verdict came a year and a day after Mr. Scrushy was found not guilty of involvement in a $2.7 billion accounting fraud at HealthSouth, which he built from scratch into America's largest provider of rehabilitative healthcare. Mr. Siegelman, a Democrat who was governor from 1999 to 2003, was also convicted of bribery and mail fraud, following a seven-week trial and 11 days of jury deliberations. Prosecutors accused Mr. Siegelman of operating a "pay to play" scheme in which companies and contractors gave political donations in return for contracts and favors. The pair could each face up to 30 years in jail for the crimes. UBS, the Swiss investment bank, was embroiled in the case through its role as former banker to HealthSouth. A former UBS banker testified that the bank had helped engineer Mr. Scrushy's payment to the lottery campaign by forgiving $250,000 in fees it was owed by a healthcare company through which the donation was funneled. Mike Martin, HealthSouth's former chief financial officer, told the jury he had put pressure on UBS, at Mr. Scrushy's behest, to help finance the donation. Mr. Scrushy denied the donation was a bribe, arguing he wanted to foster good relations with the governor and support his push to improve public education through a lottery. HealthSouth was among the raft of US companies where large scale frauds were discovered in the wake of the accounting scandals at Enron and WorldCom.

- #9 Explain to your students that most organizations want to make decisions somewhere in quadrant I, both legal and ethical Obviously this does not always happen, or we would not have examples such as Enron and Martha Stewart Can you name a company that operates in each quadrant? I – Amazon II – Microsoft – the government ruled that Microsoft was breaking antitrust laws and operating a monopoly, although Microsoft felt it was operating ethically and legally III – Some lawyers IV – Drug Dealer
- #10 For these reasons it falls on the shoulders of those who lord over the information to develop ethical guidelines on how to mange it Review the figure discussing the current established information-related laws
- #11 Organizations should develop written policies establishing employee guidelines, personnel procedures, and organizational rules These policies set employee expectations about the organization's practices and standards and protect the organization from misuse of computer systems and IT resources Are any of these policies used at your college?
- #12 For example: an ethical computer use policy might state that users should refrain from playing computer games during working hours CLASSROOM EXERCISE Analyzing An Ethical Computer Use Policy Break your students into groups and ask them to develop and define several ethical computer use policies that would be appropriate for your school or for a business of your choice. Have your students present their policies to the entire class. Examples: Users will not send spam Users will not send harmful viruses Users will not use offensive language or send offensive material Extra exercise: Have your students research the Internet for current law suits based on offensive e-mail

- #17 Most of your students probably signed an AUP when signing up with their ISP ISPs typically require each customer to sign an AUP Ask your students to rank the acceptable use policy stipulations in order of greatest importance to least importance for an ISP
- #18 Explain to your students that e-mail is not safe E-mail can easily be read by: Anyone who works for the Internet service provider Anyone who works for the recipient's Internet service provider Anyone who operates any of the perhaps dozens of Internet routers that the data packets will pass through Anyone with physical access to the telephone switching equipment in the phone company's office Do your students know that if they speak on the telephone with anyone in the United States, the telephone switching equipment at the phone company offices has wiretaps built into it for easy access by authorities - or actually anyone with the password, such as maintenance personnel. These wiretaps started appearing after the U.S. Congress passed the Digital Telephony Act, because of complaints by law enforcement that modern digital telephone systems were becoming harder to tap.

- #21 There are many reasons why an organization should implement an Internet use policy including: Large amounts of computing resources that Internet users can expend Numerous materials that some might feel are offensive Ask your students to rank the Internet use policy stipulations in order of greatest importance to least importance for an ISP
- #22 A few methods that an organization can follow to prevent spam include Disguise e-mail addresses posted in a public electronic place – instead of actually posting all of your employee e-mails on the corporate Web site, just post the name without the @xyz.com. That way spam collecting devices will not recognize the e-mail addresses and will not be able to send e-mail Opt-out of member directories that may place an e-mail address online – choose not to participate in any activities that place e-mail addresses online Use a filter – Use a spam filter to help prevent spam
- #23 The organization needs to protect itself by knowing what its employees are doing, however does it have to monitor everything throughout the workplace? It is difficult to determine when employee monitoring crosses the ethical lines What can an organization do to protect itself from such things as sexual harassment, discrimination, and other forms of unethical behavior where it can be held liable? A recent survey of workplace monitoring and surveillance practices by the American Management Association (AMA) and the ePolicy Institute showed the degree to which companies are turning to monitoring: 82 percent (of the 1,627 companies surveyed) acknowledged conducting some form of electronic monitoring or physical surveillance 63 percent stated that they monitor Internet connections 47 percent acknowledged storing and reviewing employee e-mail messages

- #26 Ask your students to rank the employee monitoring policy stipulations in order of greatest importance to least importance for an organization
- #27 This section takes a look at information security two primary lines of defense People Technology CLASSROOM OPENER GREAT BUSINESS DECISIONS – The American Express Charge Card The product that led to the question “cash or charge?” was the American Express card, or, as Forbes called it: “the late-twentieth-century piece of magic that replaced checks, money, and charge accounts.” The American Express card, and every other charge card, evolved from the company’s greatest invention, the traveler’s check, which was introduced in 1891. With an American Express traveler’s check in hand, a visitor otherwise unknown, could obtain hard cash in a matter of moments. It was a whole new concept, selling people the honor of being trusted, and it caught on. The security of carrying a traveler’s check instead of cash was one of its biggest benefits. The security of carrying a credit card instead of cash was an even bigger benefit. American Express celebrated its 100th birthday in 1950, and its staying power can be ascribed to its understanding that “A credit card, in short, is not a mere commodity, {but} it says something about the person who uses it.” The company understood that the card could be considered much more than financial security, it could be a status symbol.
- #28 Do you agree that information requires protection? What happens if all sales information for a business falls into the hands of its customers? What happens if all employee pay rates and bonus information are distributed to all employees? What happens if customer credit card numbers are posted to a Web site for anyone to view? These are a few of the reasons why it is critical that information must be highly-protected With business strategies such as CRM organizations can determine such things as their most valuable customers Why would an organization want to protect this type of information? Why does e-business automatically creates security risks? How much critical information is freely flowing over the Internet to customers, partners, and suppliers? How has HIPAA helped protect the privacy and security of personal health records? HIPAA requires health care organizations to develop, implement, and maintain appropriate security measures when sending electronic health information
- #29 Knowing how important information security is for an organization, do the above spending amounts seem correct? Why or why not? CLASSROOM EXERCISE Pizza Video You can use this video in a number of classes – it relates well to both information security and ethics http://www.adcritic.com/interactive/view.php?id=5927
- #30 The figure displays the spending per employee on computer security The highest average computer security spending per employee was in the transportation industry and federal government - not surprising after 9/11 Why is the transportation industry spending so high? Why is the medical and retail industry spending so low? Why is there such a large gap between federal government spending and local government spending?
- #31 Most information security breaches result from people misusing an organization's information either advertently or inadvertently. For example, many people freely give up their passwords or write them on sticky notes next to their computers, leaving the door wide open to intruders CLASSROOM EXERCISE Ask your students to research the Internet to find the latest version of the CSI/FBI Computer Crime and Security Survey to find the newest information on computer crime and security breeches
- #32 Have your students to review the sample information security plan in Figure 4.18 CLASSROOM EXERCISE: Break your students into groups and ask them to research and review your school’s information security plan What did the plan address that your students found surprising? What is the plan missing or failing to address? If your students were responsible for updating the plan, what would they add?
- #33 Ask your students to share any experiences they have had with social engineering through stolen passwords or identity theft If they had to try to social engineer a password from another student what would they do?
- #34 Have your students review the five steps for creating an information security plan detailed in Figure 4.19 Develop the information security policies Simple yet effective types of information security policies include: Requiring users to log off of their systems before leaving for lunches or meetings Never sharing passwords, and changing personal passwords every 60 days. Ask your students what other types of information security policies they have encountered Communicate the information security policies Train all employees and establish clear expectations for following the policies. For example – a formal reprimand can be expected if a computer is left unsecured. Identify critical information assets and risks Require the use of user IDs, passwords, and antivirus software on all systems. Ensure that systems that contain links to external networks have firewalls and IDS software. Test and reevaluate risks Continually perform security reviews, audits, background checks, and security assessment Obtain stakeholder support Gain the approval and support of the information security policies by the Board of Directors and all stakeholders
- #35 CLASSROOM EXERCISE Defending People Break your students into groups and ask them to rank the questions in order of importance Ask your students to identify any additional questions not covered in the text Have your students present their ranking and additional questions to the rest of the class This makes for an excellent debate
- #36 International Data Corp. estimated worldwide spending on IT security software, hardware, and services would top $35 billion in 2004. Organizations can deploy numerous technologies to prevent information security breaches. When determining which types of technologies to invest in, it helps to understand the three primary information security areas: Authentication and authorization Prevention and resistance Detection and response
- #37 What types of authentication are you using today? What type is used at your bank? What type is used for your online banking? Is it secure? Why or why not? What type would you like for your online banking?
- #38 Have any of you ever had your authentication method hacked? What was the outcome? How many of you have had to call a help-desk due to a password related issue?
- #39 Discuss the identity theft examples covered in Figure 4.21 An 82-year-old woman in Fort Worth, Texas, discovered that her identity had been stolen when the woman using her name was involved in a four-car collision. For 18 months, she kept getting notices of lawsuits and overdue medical bills that were really meant for someone else. It took seven years for her to get her financial good name restored after the identity thief charged over $100,000 on her 12 fraudulently acquired credit cards. A 42-year-old retired Army captain in Rocky Hill, Connecticut, found that an identity thief had spent $260,000 buying goods and services that included two trucks, a Harley-Davidson motorcycle, and a time-share vacation home in South Carolina. The victim discovered his problem only when his retirement pay was garnished to pay the outstanding bills. In New York, members of a pickpocket ring forged the driver’s licenses of their victims within hours of snatching the women’s purses. Stealing a purse typically results in around $200, if not less. But stealing the person’s identity can net on average between $4,000 and $10,000.A crime gang took out $8 million worth of second mortgages on victims’ homes. It turned out the source of all the instances of identity theft came from a car dealership. The largest identity-theft scam to date in U.S. history was broken up by police in 2002 when they discovered that three men had downloaded credit reports using stolen passwords and sold them to criminals on the street for $60 each. Many millions of dollars were stolen from people in all 50 states.
- #40 The above figure displays identity theft losses by 2005 (billions of dollars) Have any of you ever been the victim of identity theft? How did the theft occur? What was stolen? How difficult was it to recover? What could you have done to prevent the theft? A new business is growing for identity theft insurance, which costs between $15 and $50 per month. Would you purchase this insurance? Why or why not?
- #41 Smart cards can act as identification instruments, a form of digital cash, or a data storage device with the ability to store an entire medical record Identify a business opportunity that could take advantage of smart card technology? Europe is deploying smart cards for season ticket holders of soccer games. Could the U.S. use the same for NFL games? Yes, we could offer smart cards for NFL games, however, many NFL season tickets are owned be a group of people who share the tickets – how would they share a smart card?
- #42 How many of your students would like to have an iris scan performed each time they entered your classroom or took an exam?
- #43 How much it would cost eBay or Amazon.com if their systems were down for one day? One 22-hour outage in June 2000 caused eBay’s market cap to plunge $5.7 billion
- #44 How many spam messages do you receive each day? What types of preventative measures have they taken to stop spam? How many use antivirus software to prevent spam? More importantly, how many have current, up-to-date antivirus software, and how frequently do they actually run it and scan their computers for viruses? Research the Internet and find several different spam filters and antivirus software that protect computer users
- #45 How long would it take a hacker to break an encryption code on a Word document? Many hundreds of years, although on television it only take 10 minutes Research the Web to find information about encryption technologies that you can use to protect sensitive information
- #46 An important element to the public key system is that the public and private keys are related in such a way that only the public key can be used to encrypt messages and only the corresponding private key can be used to decrypt them. Moreover, it is virtually impossible to deduce the private key if you know the public key.
- #47 A firewall examines each message that wants entrance to the network, and unless the message has the correct marking, the firewall prevents it from entering the network What would happen to an organization that did not have firewalls at the entrance of its networks? This organization’s servers would not be operating for long because they would be continually hacked
- #48 A firewall examines each message that wants entrance to the network, and unless the message has the correct marking, the firewall prevents it from entering the network Point out to your students the placement of the firewalls between the servers and the Internet
- #49 A single worm can cause massive damage In August 2003, the “Blaster worm” infected over 50,000 computers worldwide and was one of the worst outbreaks of the year Jeffrey Lee Parson, 18, was arrested by U.S. cyber investigators for unleashing the damaging worm on the Internet The worm replicated itself repeatedly, eating up computer capacity, but did not damage information or programs The worm generated so much traffic that it brought entire networks down
- #50 White-hat hackers—work at the request of the system owners to find system vulnerabilities and plug the holes Black-hat hackers—break into other people’s computer systems and may just look around or may steal and destroy information Hactivists—have philosophical and political reasons for breaking into systems and will often deface the Web site as a protest Script kiddies or script bunnies—find hacking code on the Internet and click-and-point their way into systems to cause damage or spread viruses Cracker—a hacker with criminal intent Cyberterrorists—seek to cause harm to people or to destroy critical systems or information and use the Internet as a weapon of mass destruction
- #51 Worm—a type of virus that spreads itself, not only from file to file, but also from computer to computer. The primary difference between a virus and a worm is that a virus must attach to something, such as an executable file, in order to spread. Worms do not need to attach to anything to spread and can tunnel themselves into computers. Denial-of-service attack (DoS)—floods a Web site with so many requests for service that it slows down or crashes the site Distributed denial-of-service attack (DDoS)—attacks from multiple computers that flood a Web site with so many requests for service that it slows down or crashes. A common type is the Ping of Death, in which thousands of computers try to access a Web site at the same time, overloading it and shutting it down. Trojan-horse virus—hides inside other software, usually as an attachment or a downloadable file Backdoor programs—viruses that open a way into the network for future attacks Polymorphic viruses and worms—change their form as they propagate
- #52 Elevation of privilege is a process by which a user misleads a system into granting unauthorized rights, usually for the purpose of compromising or destroying the system. For example, an attacker might log on to a network by using a guest account, and then exploit a weakness in the software that lets the attacker change the guest privileges to administrative privileges.
