ABOUT HACKERS!

Concept of Ethical Hacking

Hacking

• The Art of exploring various security breaches is termed as Hacking.

• Computer Hackers have been around for so many years. Since the Internet became widely used in the World, We have started to hear more and more about hacking. Only a few Hackers, such as Kevin Mitnick, are well known.

• In a world of Black and White, it’s easy to describe the typical Hacker. A general outline of a typical Hacker is an Antisocial, Pimple-faced Teenage boy. But the Digital world has many types of Hackers.

• Hackers are human like the rest of us and are, therefore, unique individuals, so an exact profile is hard to outline.The best broad description of Hackers is that all Hackers aren’t equal. Each Hacker has Motives, Methods andSkills. But some general characteristics can help you understand them. Not all Hackers are Antisocial, Pimplefaced Teenagers. Regardless, Hackers are curious about Knowing new things, Brave to take steps and they are often very Sharp Minded.

  WHAT ARE HACKERS? IS THEY CRIMINALS

Hacker is a word that has two meanings:

 Traditionally, a Hacker is someone who likes to play with Software or Electronic Systems. Hackers enjoy Exploring

and Learning how Computer systems operate. They love discovering new ways to work electronically.

 Recently, Hacker has taken on a new meaning — someone who maliciously breaks into systems for personal gain.

Technically, these criminals are Crackers as Criminal Hackers. Crackers break into systems with malicious

intentions.

 They do it for Personal gain, Fame, Profit and even Revenge. They Modify, Delete and Steal critical information,

often making other people's life miserable.

 Hacking has a lot of meanings depending upon the person’s knowledge and his work intentions. Hacking is an Art

as well as a Skill. Hacking is the knowledge by which one gets to achieve his Goals, anyhow, using his Skills and

Power.

 Most people associate Hacking with breaking law, therefore calling all those guys who engage in hacking activities

to be criminals. We agree that there are people out there who use hacking techniques to break the law, but

hacking is not really about that. In fact, hacking is more about following the law and performing the steps within

the limits.

What Is the Difference Between a Hacker and a Cracker?
 Many articles have been written about the difference between Hackers and crackers, which attempt to correct public misconceptions about hacking. For many years, media has applied the word Hacker when it really meansCracker. So the public now believe that a Hacker is someone who breaks into computer systems and stealconfidential data. This is very untrue and is an insult to some of our most talented Hackers.
There are various points to determine the difference between Hackers and crackers.

 Definition - A Hacker is a person who is interested in the working of any computer Operating system. Most often,Hackers are programmers. Hackers obtain advanced knowledge of operating systems and programminglanguages. They may know various security holes within systems and the reasons for such holes. Hackers

TYPES OF HACKERS

Coders
 The Real Hackers are the Coders, the ones who revise the methods and create tools that are available in the 

market. Coders can find security holes and weaknesses in software to create their own exploits. These Hackers 

can use those exploits to develop fully patched and secure systems.

 

 Coders are the programmers who have the ability to find the unique vulnerability in existing software and to 

create working exploit codes. These are the individuals with a deep understanding of the OSI Layer Model and 

 

TCP/IP Stacks.

 

Admins
 Admins are the computer guys who use the tools and exploits prepared by the coders. They do not develop their 

own techniques, however they uses the tricks which are already prepared by the coders. They are generally 

 

System Administration, or Computer Network Controller. Most of the Hackers and security person in this digital 

 

world come under this category.

 

 Admins have experience with several operating systems, and know how to exploit several existing vulnerabilities. 

A majority of Security Consultants fall in this group and work as a part of Security Team.

 

Script Kiddies
 Next and the most dangerous class of Hackers is Script kiddies, They are the new generation of users of computer 

who take advantage of the Hacker tools and documentation available for free on the Internet but don’t have any 

 

knowledge of what’s going on behind the scenes. They know just enough to cause you headaches but typically are 

 

very sloppy in their actions, leaving all sorts of digital fingerprints behind. Even though these guys are the teenage 

 

Hackers that you hear about in the news media, they need minimum skills to carry out their attacks.\

 

 Script Kiddies are the bunnies who use script and programs developed by others to attack computer systems and
Networks. They get the least respect but are most annoying and dangerous and can cause big problems without
actually knowing what they are doing.


White Hat Hacker
 A White Hat Hacker is computer guy who perform Ethical Hacking. These are usually security professionals with 

knowledge of hacking and the Hacker toolset and who use this knowledge to locate security weaknesses and 

 

implement counter measures in the resources.

 

 They are also known as an Ethical Hacker or a Penetration Tester. They focus on Securing andProtecting IT 

Systems.

 

Black Hat Hacker
 A Black Hat Hacker is computer guy who performs Unethical Hacking. These are the Criminal Hackers or Crackers 

who use their skills and knowledge for illegal or malicious purposes. They break into or otherwise violate the 

 

system integrity of remote machines, with malicious intent.

 

 These are also known as an Unethical Hacker or a Security Cracker. They focus on Security Cracking and Data 

stealing.

 

Grey Hat Hacker
 A Grey Hat Hacker is a Computer guy who sometimes acts legally, sometimes in good will, and sometimes not.

They usually do not hack for personal gain or have malicious intentions, but may or may not occasionally commit 

 

crimes during the course of their technological exploits.
