The ethical hacker(also known
as white hat hacker) is that, who discover security holes in your systems and
make it secure ! The ethical hacker works like a cracker to find
vulnerabilities, potential threats that could be exploited by other hackers.
Remember, Attack is the best defence so always think in a hacker's way.If you are serious about your hacking career and want to become an professional ethical hacker, follow these steps:
1. Learn about computer system :- An ethical hacker should have a good knowledge about operating systems.The Problem is most programmers are not good computer scientist. That's why vulnerabilities are found in their software. So first learn computer architecture ! If you are a windows user, then move to linux. Because linux is everywhere like server, Desktop, satellites, TV etc. Most of web server works on linux. Go to YouTube and google for learning LINUX.I recommend you've been to use Kali-Linux.
2. Learn Programming :- Remember, Hackers are
programmers.The difference is in way of thinking only. you can be a fairly good
ethical hacker without knowing any programming But people will still classify
you as a script kiddie. As Many peoples don't know from where to start. I suggest
you to learn HTML and python first. There are mostly two types of hackers
:
Computer hacker Web-hacker
If you want to be a computer hacker, then have to learn three programming language:
C/C++ : Most of Operating systems are written in C/C++. it is also used for Exploit writing and development. In Programming
Python : Python is becoming the natural leader in the hacking- programming language department.Python is the language of choice for hackers and security analysts for creating powerful and effective tools.it is most used language for exploit writing.
Assembly Language : If your computer can do something, you can write assembly code to do it. Assembly language is probably the most important things one needs to master if he/she desire to enter the world of hacking.A hacker that hasn't mastered Assembly language is not a hacker because nothing really moves without it.Reverse Engineers also uses Assembly language.
If you want to be a web hacker, then have to
learn these programming language:
HTML : it is so easy to learn. A hacker must have basic knowledge about HTML which makes easy to understand web pages,XSS , phishing etc. When there is a vulnerability in victim’s website, a hacker must have a little idea about what it is. Hence he must get used to HTML to identify and take control over the website!
JavaScript : It is client-side programming language. if you want to exploit Client side vulnerabilities, then you need javascript and html knowledge.
PHP : It is server-side programming language.it is strongly recommended to every web Penetration tester.
A very good resource of learning PHP : PHP at the Core: A Hacker's Guide
SQL : Structured Query Language is database programming language.Most of you heard about SQL injection. To exploit SQL injection vulnerability in websites, You must have knowledge of SQL programming and PHP.
3.Learn networking :- An ethical hacker should have knowledge about how network operates and networking term like IP/TCP, port, protocol, router, modem and many more terms. If you want to be good in networking then you can set up your own home network. II suggest you to learn: How network work, what is TCP/IP, About Protocols and port, About OSI model. Networking helps in Developing remote exploits, Attacking network application like SMTP, FTP etc.

4. Join hackers forums :- Join ethical hacking Groups on social websites like Facebook, Twitter etc. Subscribe to hacker news websites. join ethical hacking communities like HackThisSite, Black-Hat Forums etc...
5. Working of an ethical hacker :-
-> Working ethically.
-> Respecting Laws.
-> Not harm systems.

8. Important Toolkit for Ethical Hackers and Penetration testers:
Kali-linux : Kali Linux is an advanced
Penetration Testing and Security Auditing Linux distribution.It has more than
300 penetration testing tools.
Metasploit: This is the most advanced and popular Framework that can be used to for pen-testing. It is based on the concept of ‘exploit’ which is a code that can surpass the security measures and enter a certain system.
Namp: This is a very popular tool that predominantly aids in understanding the characteristics of any target network. The characteristics can include: host, services, OS, packet filters/firewalls etc. It works on most of the environments and is open sourced.
Wireshark :Wire-shark is a network packet analyzer. A network packet analyzer will try to capture network packets and tries to display that packet data as detailed as possible. Penetration test tools like Wireshark come in handy for understanding and exploiting the data organization posted by forms or services to applications. Application vulnerabilities such as parameter pollution, SQL injection, lack of input validation, as well as buffer overflow can be easily detected and exploited using Wireshark.
Nessus: Nessus is a great tool designed to automate the testing and discovery of known security problems. Typically someone, a hacker group, a security company, or a researcher discovers a specific way to violate the security of a software product.
Cain & Abel : Cain and abel is one of best Tool that is commonly used to Poison the network If cracking encrypted passwords or network keys is what you need, then Cain& Abel is the tool for you. It uses network sniffing, Dictionary, Brute-Force and Cryptanalysis attacks, cache uncovering and routing protocol analysis methods to achieve this.
John The Ripper : This is the most powerful password cracker tool. This tool works on most of the environments, although it’s primarily for UNIX systems. It is considered one of the fastest tools in this genre. Password hash code and strength-checking code are also made available to be integrated to your own software/code.
OWASP Mantra : Mantra is a browser especially designed for web application security testing.Mantra has many built in tools to modify headers, manipulate input strings, replay GET/POST requests, edit cookies, quickly switch between multiple proxies, control forced redirects etc. This makes it a good software for performing basic security checks and sometimes, exploitation. Thus, Mantra can be used to solve basic levels of various web based CTFs, showcase security issues in vulnerable web applications etc.
Acunetix: Acunetix is essentially a web vulnerability scanner targeted at web applications. It provides SQL injection, cross site scripting testing, PCI compliance reports etc. along with identifying a multitude of vulnerabilities.
Burp Suite : This tool is used to performing a Web Application Penetration Test. Burp Suite contains all the Burp interfaces and tools made for speeding up and facilitating the process of application attacks.
Havij pro : Havij is an automated SQL Injection tool that helps penetration testers to find and exploit SQL Injection vulnerabilities on a web page. It can take advantage of a vulnerable web application. By using this software, user can perform back-end database fingerprinting, retrieve DBMS login names and password hashes, dump tables and columns, fetch data from the database, execute SQL statements against the server, and even access the underlying file system and execute operating system shell commands.
