Ethical Hacking.....

First lets talk about Hackers and hacking. Who is Hackers and what they do? Can hacking be ethical ? Ok, Hackers are those who enjoys entering any computer system either legally or illegally, breaks the security, and extract the capabilities of the system, Generally hackers refers to "a Clever Programmer" and also sometimes "a Security Professional". And the terms hacking is a process of breaking security and extracting details of the system. It is something like developing a new program  or reverse engineering of already existing program or software. Most of the people thinks that 'Hackers' and 'Crackers' are the same thing. But I'll like to confess them that those hackers who use their hacking skills for offensive and illegal purposes are known as Crackers. And those (lets say Security Professional) who use their skills for defensive purposes are known as Ethical Hackers.

    Ok then how they breaks the security of the system ? Before that lets talk about some essential terminology.

• Threat : Threats is an action or event that potentially violets the security.
• Vulnerability : It is an unexpected errors or weaknesses of a system that can leads to unwanted or undesirable activities compromising the security of the system.
• Attack : It is an action or task that violets the security which is derives from an intelligent threats.
• Exploits : It is an well defined method to break the security through the vulnerability.

    I have excessively used the term 'Security' till now. Ok then what is Security ? Security (more conveniently  IT Security) is a state of well-being of information and infrastructures in which the possibility of successful yet undetected theft, tempering and disruption of information and services is kept low or tolerable. 

     Now lets talk about types of Hackers. Depending upon their pre and post hacking activities the hackers can be classified in following category: 

• Black Hats Hackers : Those hackers having extraordinary hacking and programming skills and mostly use their skills for offensive purposes are known as Black Hats Hackers. Usually these hackers are refer as a Crackers.
• White Hats Hackers : Those hackers who use their skills for defensive purposes are known as White Hats Hackers. Usually they are Ethical Hackers and and also known as "System Analysts".
• Grey Hats Hackers : Those hackers who work both offensively or defensively are known as Grey Hats Hackers.

Ethical Hackers are further classified in following classes:

• Former Blacks Hats Hackers
• White Hats Hackers
• Consulting Firms... etc.

     What are the skills a Ethical Hackers exhibits ? Ethical hackers are computer expert adept at technical domains. They have in-depth knowledge about target platforms or OS (such as Windows, Mac, Unix, Linux etc.). They have sufficient knowledge about networking and related hardware & software. They may not be a Security Professional but they exhibits sound knowledge about Security areas and other related fields & issues.
