- 3. Ethical hacking also known as penetration testing or white-hat hacking, involves the same tools, tricks, and techniques that hackers use, but with one major difference that Ethical hacking is legal. Ethical hacking, is legally breaking into computers and devices to test an organization's defenses.
- 4. Independent computer security Professionals breaking into the computer systems. Neither damage the target systems nor steal information. Evaluate target systems security and report back to owners about the vulnerabilities found.
- 5. A person who enjoys learning details of a programming language or system A person who enjoys actually doing the programming rather than just theorizing about it A person capable of appreciating someone else's hacking A person who picks up programming quickly A person who is an expert at a particular programming language or system
- 6. Black Hat Hacker White Hat Hacker Grey Hat Hacker
- 7. A black hat hackers or crackers are individuals with extraordinary computing skills, resorting to malicious or destructive activities. That is black hat hackers use their knowledge and skill for their own personal gains probably by hurting others.
- 8. White hat hackers are those individuals professing hacker skills and using them for defensive purposes. This means that the white hat hackers use their knowledge and skill for the good of others and for the common good.
- 9. These are individuals who work both offensively and defensively at various times. We cannot predict their behavior. Sometimes they use their skills for the common good while in some other times he uses them for their personal gains.

- 13. Password Attacks Social Engineering Viruses
- 14. Os BackDoors Trojans Clears Tracks
- 15. Viruses, Trojan Horses, and Worms Social Engineering Automated Attacks Accidental Breaches in Security Denial of Service (DoS) Organizational Attacks Restricted Data Protection from possible External Attacks
- 16. Microsoft: skills in operation, configuration and management. Linux: knowledge of Linux/Unix; security setting, configuration, and services. Firewalls: configurations, and operation of intrusion detection systems.
- 17. Routers: knowledge of routers, routing protocols, and access control lists Mainframes Network Protocols: TCP/IP; how they function and can be manipulated. Project Management: leading, planning, organizing, and controlling a penetration testing team.
- 18. Patch Security hole The other hackers can’t intrude Clear logs and hide themselves Install rootkit ( backdoor ) The hacker who hacked the system can use the system later It contains trojan virus, and so on Install irc related program identd, irc, bitchx, eggdrop, bnc
- 19. Install scanner program mscan, sscan, nmap Install exploit program Install denial of service program Use all of installed programs silently
- 20. ‘’To catch a thief you have to think like a thief” Helps in closing the open holes in the system network Provides security to banking and financial establishments Prevents website defacements An evolving technique
- 21. All depends upon the trustworthiness of the ethical hacker Hiring professionals is expensive.
- 22. As it an evolving branch the scope of enhancement in technology is immense. No ethical hacker can ensure the system security by using the same technique repeatedly. More enhanced software’s should be used for optimum protection.
- 23. In the preceding sections we saw the methodology of hacking, why should we aware of hacking and some tools which a hacker may use. Now we can see what can we do against hacking or to protect ourselves from hacking. The first thing we should do is to keep ourselves updated about those software’s we and using for official and reliable sources. Educate the employees and the users against black hat hacking.
