15. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice HallID4-15 International computer crime is common. Web sites operated in African countries phish for data in the United States. A scam in the United States steals data from a U.S. corporation and sells that data to an illegal operation in South America. Someone kidnaps a U.S. citizen in a foreign country and sends an email ransom demand to relatives in the United States. The email service provider is located in a Middle Eastern country. Challenges Exist for Investigating Global Computer Crime

16. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice HallID4-16 U.S. criminal investigator can obtain evidence only with consent of the country in which evidence lies. Most nations have laws, agreements, and treaties for cooperating in criminal investigations, but formal process for obtaining permission to search is slow and cumbersome. Some nations will not cooperate. G8 group of nations developed a 24-hour point-of- contact system. System, used by more than 30 nations, requires each country to staff an office that can speed processing of permission for evidence gathering. Challenges Exist for Investigating Global Computer Crime

17. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice HallID4-17 Evidence-gathering facilitated by informal arrangements among individuals in security agencies and organizations. However, law regarding admissibility of such evidence in court is complicated. U.S. Fourth Amendment can apply in complex ways to searches outside United States. The law for gathering evidence for computer crimes in United States is complicated, and even more so for international investigations. Organizations that suspect they have been victims of a computer crime, especially international computer crime, should seek legal counsel, first.

19. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice HallID4-19 United States Internal Revenue Service (IRS) Business Systems Modernization (BSM) project has been a multiyear attempt to replace existing tax-processing information systems with systems based on modern technology Subsystem that has generated most controversy and caused most serious delays is the Customer Account Data Engine (CADE). The heart of CADE is a database of business rules. IRS database contains rules about tax laws and processing of tax forms.  Example of a rule: Rule 10 IF the amount on line 7 of Form 1040EZ is greater than zero, THEN invoke Rule 15. With a rule-based approach, IRS needs to only develop programs that access the database and follow the rules. Case 4: The Need for Technical Feasibility

20. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice HallID4-20 Using traditional technology, developers interview users, determine what the business rules are, and then write computer code that operates in accordance with the rules. Disadvantage of such traditional programming is that only technically trained programmers can decipher the rules in the program code. Also, only trained programmers can add, change, or delete rules. Advantage of rule-based systems such as CADE is that the business rules are stored in the database and can be read, added, changed, or deleted by personnel with business knowledge but little computer training. Hence, in theory, CADE is more adaptable to changing requirements than a system written with traditional programming languages. Case 4: The Need for Technical Feasibility

21. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice HallID4-21 Technical feasibility of using a rule-based system for a problem as large and complex as IRS tax processing is unknown. No one tried to estimate that feasibility. Result has been a string of schedule delays and cost overruns. Database for simple returns has some 1,200 business rules, but no reliable estimate has yet been developed for the number of rules required for the full system. Some experts believe difficulty and complexity of creating rules increases geometrically with the number of rules. Case 4: The Need for Technical Feasibility

22. Copyright © 2011 Pearson Education, Inc. Publishing as Prentice HallID4-22 Software Engineering Institute of (SEI) Carnegie Mellon University verified that no one knows with any certainty how many business rules will eventually be required. “No one knows how long rule harvesting will take, how many people will be required, the background, training, and experience of the people required, or how much it will cost. Based on anecdotal information presented to us, we believe the time will be measured in years and cost will be measured in the tens of millions of dollars. Case 4: The Need for Technical Feasibility
