1 13 Security and Ethical Challenges

2 IT Security, Ethics, and Society IT has both beneficial and detrimental effects on society and people  Manage work activities to minimize the detrimental effects of IT  Optimize the beneficial effects 2

3 Case: Catching Cases of Plagiarism Problem: The Internet provides abundant information to students who may be tempted to download material and submit it as their own work. Solution: Some companies (e.g., Plagiarism.org) are offering Internet-based anti-plagiarism technology to identify such cases of plagiarism. Manuscript are checked against a database of other manuscripts collected from different universities and from all over the Internet. Results: Cases of gross plagiarism are more likely to be flagged.

4 Business Ethics 4 Ethics questions that managers confront as part of their daily business decision making include:  Equity  Rights  Honesty  Exercise of corporate power Categories of Ethical Business Issues

5 Corporate Social Responsibility Theories Stockholder Theory  Managers are agents of the stockholders  Their only ethical responsibility is to increase the profits of the business without violating the law or engaging in fraudulent practices Social Contract Theory  Companies have ethical responsibilities to all members of society, who allow corporations to exist Stakeholder Theory  Managers have an ethical responsibility to manage a firm for the benefit of all its stakeholders  Stakeholders are all individuals and groups that have a stake in, or claim on, a company 5

6 AITP Standards of Professional Conduct 6

7 Responsible Professional Guidelines A responsible professional  Acts with integrity  Increases personal competence  Sets high standards of personal performance  Accepts responsibility for his/her work  Advances the health, privacy, and general welfare of the public 7

8 Computer Crime Computer crime includes  Unauthorized use, access, modification, or destruction of hardware, software, data, or network resources  The unauthorized release of information  The unauthorized copying of software  Denying an end user access to his/her own hardware, software, data, or network resources  Using or conspiring to use computer or network resources illegally to obtain information or tangible property 8

9 Cybercrime Protection Measures 9

10 Hacking Hacking is  The obsessive use of computers  The unauthorized access and use of networked computer systems Electronic Breaking and Entering  Hacking into a computer system and reading files, but neither stealing nor damaging anything Cracker  A malicious or criminal hacker who maintains knowledge of the vulnerabilities found for private advantage 10

11 Common Hacking Tactics Denial of Service  Hammering a website’s equipment with too many requests for information  Clogging the system, slowing performance, or crashing the site Scans  Widespread probes of the Internet to determine types of computers, services, and connections  Looking for weaknesses Sniffer  Programs that search individual packets of data as they pass through the Internet  Capturing passwords or entire contents Spoofing  Faking an e-mail address or Web page to trick users into passing along critical information like passwords or credit card numbers 11

12 Common Hacking Tactics Trojan House  A program that, unknown to the user, contains instructions that exploit a known vulnerability in some software Back Doors  A hidden point of entry to be used in case the original entry point is detected or blocked Malicious Applets  Tiny Java programs that misuse your computer’s resources, modify files on the hard disk, send fake email, or steal passwords War Dialing  Programs that automatically dial thousands of telephone numbers in search of a way in through a modem connection Logic Bombs  An instruction in a computer program that triggers a malicious act 12

13 Common Hacking Tactics Buffer Overflow  Crashing or gaining control of a computer by sending too much data to buffer memory Password Crackers  Software that can guess passwords Social Engineering  Gaining access to computer systems by talking unsuspecting company employees out of valuable information, such as passwords Dumpster Diving  Sifting through a company’s garbage to find information to help break into their computers 13

39 Internetworked Security Defenses Encryption  Data is transmitted in scrambled form  It is unscrambled by computer systems for authorized users only  The most widely used method uses a pair of public and private keys unique to each individual 39

40 Public/Private Key Encryption 40

41 Internetworked Security Defenses Firewalls  A gatekeeper system that protects a company’s intranets and other computer networks from intrusion  Provides a filter and safe transfer point for access to/from the Internet and other networks  Important for individuals who connect to the Internet with DSL or cable modems  Can deter hacking, but cannot prevent it 41

42 Internet and Intranet Firewalls 42

43 Denial of Service Attacks Denial of service attacks depend on three layers of networked computer systems  The victim’s website  The victim’s Internet service provider  Zombie or slave computers that have been commandeered by the cybercriminals 43

44 Defending Against Denial of Service At Zombie Machines  Set and enforce security policies  Scan for vulnerabilities At the ISP  Monitor and block traffic spikes At the Victim’s Website  Create backup servers and network connections 44

45 Internetworked Security Defenses Email Monitoring  Use of content monitoring software that scans for troublesome words that might compromise corporate security Virus Defenses  Centralize the updating and distribution of antivirus software  Use a security suite that integrates virus protection with firewalls, Web security, and content blocking features 45

46 Other Security Measures 46 Security Codes  Multilevel password system  Encrypted passwords  Smart cards with microprocessors Backup Files  Duplicate files of data or programs Security Monitors  Monitor the use of computers and networks  Protects them from unauthorized use, fraud, and destruction Biometrics  Computer devices measure physical traits that make each individual unique  Voice recognition, fingerprints, retina scan Computer Failure Controls  Prevents computer failures or minimizes its effects  Preventive maintenance  Arrange backups with a disaster recovery organization

47 Other Security Measures In the event of a system failure, fault-tolerant systems have redundant processors, peripherals, and software that provide  Fail-over capability: shifts to back up components  Fail-save capability: the system continues to operate at the same level  Fail-soft capability: the system continues to operate at a reduced but acceptable level A disaster recovery plan contains formalized procedures to follow in the event of a disaster  Which employees will participate  What their duties will be  What hardware, software, and facilities will be used  Priority of applications that will be processed  Use of alternative facilities  Offsite storage of databases 47

48 Auditing IT Security IT Security Audits  Performed by internal or external auditors  Review and evaluation of security measures and management policies  Goal is to ensure that that proper and adequate measures and policies are in place 48

49 Protecting Yourself from Cybercrime 49

50 Chapter Summary The vital role of e-bBusiness and e-commerce systems in society raises serious ethical and societal issues in terms of their impact on employment, individuality, working conditions, privacy, health, and computer crime. Managers can help solve the problems of improper use of IT by assuming their ethical responsibilities for ergonomic design, beneficial use, and enlightened management of e-business technologies in our society.

51 Chapter Summary (cont) Business and IT activities involve many ethical considerations. Ethical principles and standards of conduct can serve as guidelines for dealing with ethical businesses issues. One of the most important responsibilities of the management of a company is to assure the security and quality of its e-business activities. Security management tools and policies can ensure the accuracy, integrity, and safety of e-business systems and resources.
