Hacking involves obtaining private information from a target without authorization in order to check their security vulnerabilities. There are three main types of hackers: white hat hackers who perform legal security testing, black hat hackers who illegally steal data, and gray hat hackers who may behave like either. Ethical hacking, also called white hat hacking, involves legally testing a system's defenses to identify weaknesses and help organizations patch them before criminals can exploit them. Becoming an ethical hacker requires training through a certification program to develop skills in areas like networking, cryptography, and web application security testing.

2. WHAT IS HACKING ?
Hacking is not which you see in the Movies, Tv Shows or Webseries….
Where a particular person opens something and clicks on a button to hack
the phone or computer and shows that he is hacking something….
Like this
Hacking is nothing but to Get Private Information and Useful
Data of A Victim or Target, and to Check if the Target is
Vulnerable to attack or not.
Here Vulnerability means the capacity or the security of the
target is Low or Powerful.
Here Is The Actual Image Of A Wifi Hacking or Attack.

3. TYPES OF HACKERS.
There are Overall 3 Types Of Hackers to Know.
 WHITE HAT HACKERS (ETHICAL HACKERS) – These are the Most
Demanded and All Time Needed Hackers who are Hired by the
Top IT Companies for Their Security and Safety, as they work by
taking the rights from the Main Admin of the Company or
Society and hacks in a legal way.
 BLACK HAT HACKERS (UNETHICAL HACKERS) – These are the
one which are the Most Wanted Hackers and the Dangerous
Attackers in Our Society. These guys do not get any job
opportunities as they Work On Their Own By Illegally Hacking
Any System And Getting Private Data of any Computer or User
for their own purpose.
 GRAY HAT HACKERS (UNIDENTIFIED HACKERS) – These are the
most Confusing Hackers or you can say that they cannot be
identified. As these are the Combo of the Above Two Hackers.
They also work in Company’s and Legally Do Their Work and
When Out Of Work They Also Hack Illegally For Their Own
Purpose as Black Hat Hackers Do Without Getting Restricted.

4. WHAT IS ETHICAL HACKING ?
As Mentioned Above, Ethical Hacking is Nothing But
White Hat Hacking
Where a Hacker or a Attacker Attacks Legally on The
Victim or Target To Check If His/Her System is
Vulnerable or Not… By using some Penetration
Testing Skills. Then Capturing the Bugs and
Reporting To the Main Admin To Secure Their System
From Attackers. (Black Hat Hackers).
There are Number of Black Hat Hackers increasing Day
by Day, Who Steal Your Data and Go Away Unknown.
Like China Did …..
They Hacked Indian Citizens Important Data Just by
Sending A Simple Photo through Whatsapp Groups,
Facebook, and other Social Media Platforms…..
This Was Nothing But Steganography…. A method to
hide malicious(virus) file into a simple data like
image, audio or video.
Due To All of These Cases…. There is the Mostly Need of An Ethical
Hacker to Hire in Companies. These Ethical Hackers Also Get A Good
Amount Of Payment as per Their Post Or Job.
