ETHICAL HACKING A LICENCE TO HACK

1. ETHICAL HACKINGA LICENCE TO HACK Submitted By: UshaKalkal M.Tech(1stSem) Information technology

2. NEED OF ETHICAL HACKING • Companies are worried about the possibility of being “hacked” and potential customers are worried about maintaining control of personal information. • Ethical Hacking is not an automated hacker program rather it is an audit that both identifies the vulnerabilities of a system and provide advice on how to eliminate them. • To catch a thief ,think like a thief.

3. WHO IS A HACKER • A Person who enjoys learning the details of computer systems and how to stretch their capabilities. • One who program enthusiastically. • Enjoys programming rather than just theorizing about it.

4. Kind of Hackers • Old School Hackers:1960s style Stanford or MIT hackers. Do not have malicious intent, but do have lack of concern for privacy and proprietary information. They believe the Internet was designed to be an open system. • Script Kiddies or Cyber-criminals:Between 12-30; bored in school; get caught due to bragging online; intent is to vandalize or disrupt systems. • Professional Criminals or Crackers:Make a living by breaking into systems and selling the information. • Coders and Virus Writers:See themselves as an elite; programming background and write code but won’t use it themselves; have their own networks called “zoos”; leave it to others to release their code into “The Wild” or Internet.

7. INTRODUCTION • Ethical hacking is a scheme of having independent computer security professionals who attempt to break into the system to find vulnerabilities in the system. • Dynamic process. • Also known as penetration testing. • Neither damage the target systems nor steal information. • Evaluate target systems security and report back to owners about the vulnerabilities found.

8. The Role of Security and Penetration Testers • Hackers • Access computer system or network without authorization • Breaks the law; can go to prison • Crackers • Break into systems to steal or destroy data • U.S. Department of Justice calls both hackers • Ethical hacker • Performs most of the same activities but with owner’s permission

9. The “Ethical Hacker” Someone who is • Skilled • Programming and networking skills • Installation and maintenance skills • System management skills • Knowledgeable • Hardware and software • Trustworthy • Patient and Persistent • Certified

10. Get Out of Jail Free Card • When doing a penetration test, have a written contract giving you permission to attack the network • Using a contract is just good business • Contracts may be useful in court • Have an attorney read over your contract before sending or signing it

11. TYPES OF HACKER Black Hat Hacker:Use knowledge for personal gain. White Hat Hacker:Use skills for defensive purposes. Grey Hat Hacker: Work both offensively & defensively.

12. METHODOLOGY OF HACKING Five steps of hacking: • Footprinting • Scanning and enumeration • Gaining access • Maintaining access • Clearing tracks

13. FOOTPRINTING • Objective Target Address range, namespace, acquisition and information gathering are essential to a surgical attack. • Techniques & Tools • Open source search • Samspade • Email tracker & visual route

14. SCANNING & ENUMERATION • Objective Make blue print of target network. • Techniques & Tools • War dialing • Pinger • Port Scanning • Nmap(Network Mapper) • Enumeration

15. GAINING ACCESS • Objective Enough data has been gathered at this point to make an informed attempt to access the target. • Techniques & Tools • Password eavesdropping • LoftCrack • Priviledge Escalation • Metaspoilt • Man in Middle Attack

16. MAINTAINING ACCESS • Objective Now hacker is inside the system. Next aim is to make an easier path to get in when he comes next time. • Techniques & Tools • Key Stroke Logger • Create rogue user accounts • Infect startup files • Install monitoring mechanisms • Wrappers • Replace applications with trojans • Elitewrap

17. CLEARING TRACKS • Objective Once total ownership of the target is secured, hiding the fact that hacker is here from system administrators becomes paramount. • Techniques & Tools • Auditpol.exe • Eslave • Evidence Eliminator • Winzapper

18. Social Engineering Automated Attacks Organizational Attacks Restricted Data Accidental Breaches in Security Denial of Service (DoS) Viruses, Trojan Horses, and Worms Different kinds of system attacks

19. SITE BEFORE ATTACK

20. SITE AFTER ATTACK

21. ADVANTAGES • Helps in closing the open holes in the system network • Provides security to banking and financial establishments • Prevents website defacements • An evolving technique

22. DISADVANTAGES • All depends upon the trustworthiness of the ethical hacker. • Hiring professionals is expensive.

23. CONCLUSION Main aim of seminar is to make you understand that there are so many tools through which a hacker can get in to a system. Various needs from various perspectives: • Student:A student should understand that no software is made with zero Vulnerabilities. • Professionals: Professionals should understand that business is directly related to Security. So they should make new software with vulnerabilities as less as possible. • Users: If software is highly secure but user is unaware of security then it would be like a secured building with all doors open by insider.
