What is Ethical Hacking?

Ethical Hacking is done by the skilled computer experts by their excellent programming skills. It is an attempt to penetrate or crash the computer system. An ethical hacker is a computer and network expert who attacks a security system on behalf of its owners, seeking vulnerabilities that a malicious hacker could exploit. It is performed to increase the safety of the computer systems. Normally hacker prevent their company in is that owns the system and specifically to prevent others from attacking it. The command prompt is one of the most important things to become a hacker.
  

Getting Started    

What you need to do to get started on the road to becoming an ethical hacker depends on where you are in the IT field. If you haven't started your IT career yet, you might even consider military service. The military offers many IT opportunities, and you get paid to go to school, even if you enlist in a part-time branch such as the National Guard or Reserves. Military service also looks good to employers that require security clearances.
Start with the basics: Earn your A+ Certification and get a tech support position. After some experience and additional certification (Network+ or CCNA), move up to a network support or admin role, and then to network engineer after a few years. Next, put some time into earning security certifications (Security+, CISSP, or TICSA) and find an information security position. While you're there, try to concentrate on penetration testing--and get some experience with the tools of the trade. Then work toward the Certified Ethical Hacker (CEH) certification offered by the International Council of Electronic Commerce Consultants (EC-Council for short). At that point, you can start marketing yourself as an ethical hacker.
For a hacker, networking know-how is vital; but make sure that you gain experience in related areas as well. Discover and play with Unix/Linux commands and distributions. Make sure you also learn some programming--maybe C, LISP, Perl, or Java. And spend some time with databases such as SQL.

 

1. Programming

We call programmer as creator and hacker as destroyer but that is not true. We can say hacker as security analyst who find the flaws on the programs and help programmer to make it more secure. To do this, A hacker must have knowledge of programming . Earlier, I have posted two article: how to become good programmer and Best websites to learn programming. you must read those article if you are starting to learn programming and want to become an expert.

 

2. Networking

The knowledge of networking is very essential because all we do is on network. And improving the network security (cyber security) is what i call ethical hacking.

 

3. cryptography

Cryptography concept in cyber security is used to secure the information travelling through the wires or wireless media. Mainly there are two concepts in cryptography : Encryption and Decryption . You will need to learn how information is being encrypted and how decrypted and what are the methods .

 

4. Database Management system

All the data on internet is saved somewhere in databases. And these databases contain very important and sensitive information which must be only visible to authorize person .  To be an ethical hacker, you must have to know how data is stored , how data is retrieved and how it become insecure.

 

5. Linux

If you want to play games, listen music, watch movies and work in office than i’ll prefer windows but if you want to be a hacker i’ll prefer linux. and it has been already posted in technotification : why hacker prefer linux.
