Often because of the way one is raised, ethics and religion are coupled; but ethics is not confined to religion nor is the same as religion. Being ethical is not solely following the law Elements of practical ethics through basic philosophy: – Ethical thought – Ethical definition – Ethical values Example: “If a person conceives of engineering activity as only making money, then one's definition of practical ethics, one's actions and values will, be guided by this basic philosophical position. “ Security in: – Client / Workstation / Terminal – Intranetworks – Internetworks In terms of: – Physical Security Professional Practices in Information Technology CSC 110 – NonPhysical Security Security Threats (sources, causes, people behind): – Hackers – Crackers – Script Kiddies – Unethical Employees (logic bombs, backdoor,…) – Cyberterrorists – Corporate Spy – Worm / Virus / Trojan (incl. keyloggers,…) – Spoofing / Sniffing / Phishing – DoS / DDoS attacks Examples: Professional Practices in Information Technology CSC 110 Example of Phishing: Professional Practices in Information Technology CSC 110 21.2 Hackers’ Code of Ethics: Hacker creed (Steven Levy’s “Hackers: Heroes of Computer Revolution” 1984 ): – Access to computers should be unlimited and total. – Always yield to the HandsOn Imperative – All information should be free. – Mistrust authority promote decentralization. – Hackers should be judged by their hacking. – You can create art and beauty on a computer. – Computers can change your life for the better. Professional Practices in Information Technology CSC 110 New Code of Ethics (90s) Steven Mizrach : – "Above all else, do no harm" – Protect Privacy – "Waste not, want not." – Exceed Limitations – The Communicational Imperative – Leave No Traces – Share! – Self Defense – Hacking Helps Security – Trust, but Test! In Short : 1) protect data and hardware 2) respect and protect privacy 3) utilize what is being wasted by others 4) exceed unnecessary restrictions 5) promote peoples' right to communicate 6) leave no traces 7) share data and software 8) be vigilant against cybertyranny and 9) test security and system integrity of computer systems New(er) Hacker Ethics: Professional Practices in Information Technology CSC 110 Hackers share and are willing to teach their knowledge.Hackers are skilled. Many are selftaught, or learn by interacting with other hackers. Hackers seek knowledge. This knowledge may come from unauthorized or unusual sources, and is often hidden.Hackers like to understand how things work, and want to make their own improvements or modifications. Hackers often disagree with authority, including parents, employers, social customs and laws. They often seek to get around authority they disagree with.Hackers disagree with each other. Different hackers have different values, and come from all backgrounds. This means that what one hacker is opposed to might be embraced by another. Hackers are persistent, and are willing to devote hours, days and years to pursuing their individual passions. This Code is not to prescribe how hackers act. Instead, it is to help us to recognize our own diversity and identity. Every hacker must make his or her own decisions about what is right or wrong, and some might do things they believe are illegal, amoral or antisocial. Hackers' motivations are their own, and there is no reason for all hackers to agree.Hackers have a shared identity, however, and many shared interests.By reading this Code, hackers can recognize themselves and each other, and understand better the group they are a part of Hackers’ Code of Ethics: – Old code vs new code – Are new hackers aware of the original hacker ethics? – Are new hackers aware of any hacker ethics? – Influence of technology and social issues on changes in hacker ethics – Similarity between the old and new ethics and ethical continuity Professional Practices in Information Technology CSC 110 21.3 Ethical Issues in Security Courses More security subjects are moved from graduate level to undergraduate level; graduate students are more mature than undergraduate ones. Are security courses’ materials really appropriate? (Some include: trying DDOS, writing and spreading a virus,…) Major of computer hackers are under the age of 25 and many of them are college students. Using hacking tools in labs and classes increases “comfort level” with such tools the more comfortable people become with one computer technology, the more likely they are to use them There are many justifications for teaching such sensitive issues: to strengthen the nation’s defense against attacks. But do we need to know the details of how to make a bomb in order to defend ourselves against bomb attacks? Using password crackers is not necessary to teach the dangers of using weak and insecure passwords “Students would learn them on their own anyway We are presenting this material in a responsible manner.” The big question is: how to really present this material in a responsible manner? Requiring students to sign a statement and take an ethical oath? Teaching ethical issues as part of a course? Problem: ethical standards cannot be integrated in individuals just over a short period of time! Ethical subjects are necessary especially in computer security curricula. Ethical standards should be taught to students early in the program and students should be reminded of them throughout the program. Students should become aware about the consequences of misuse of their knowledge The problem of “deindividualism” (group size, anonymity) “Deindividualism is a feeling of separation and anonymity that can lead to individuals engaging in a broader range of unethical behaviors.” “Deindividuation is the psychological state of separation of the individual from others”. It is often seen in chat rooms and message boards Making students aware that they are trusted with something important encourages them to live Professional Practices in Information Technology CSC 110 up to that trust Sensitive topics should be taught and discussed at higher levels of a program ...
