What is ethical hacking?

We all know about 'Hacking'. It's penetrating into someone's system without their permission. An 'Ethical Hacker' is that good hacker, who finds potential threats in a system, to stop other hackers from penetrating into them. 

So, there are three types of hackers: White hat hackers or ethical hackers, grey hat hackers, black hat hackers. 

Black hat hackers are those who hack for their own purposes and do harm to the system. Black Hat hacking is illegal and black hat hackers are actually criminals. Grey hat hackers are actually those hackers who hack just for fun. They don't have a particular reason to hack, and most of the time they don't do any big harm to the system. Grey Hat hacking is also illegal. 

And finally, they added white hat hackers, good hackers who try to penetrate into a system to find out its vulnerabilities. A white hat hackers finally make a report of the vulnerabilities he had found and all the process he has done to penetrate into that system and submit it to the authority. Here the authority can be the system administrator or a company who has hired that ethical hacker. 

Some Books You Should Read :

Ethical hackers must maintain these responsibilities:

Number 1, he must have the proper written permission to penetrate into that system, from the system administrator. if an Ethical Hacker tries to hack into a company's system or website, then the hacker must have permission from the company to penetrate into their system and find out the vulnerabilities. 

Number 2, he must respect the individual's or the company's privacy. 

Number three, he must inform the system authority about the vulnerabilities he had found. 

And ethical hacker can work towards being a CEH, a certified ethical hacker. The best certification is done from EC Council. 

Some people think that hacking is hacking, there are no such words like ethical hacking or black Hat hacking. But it's not true. Ethical hackers hack for the good, reports vulnerabilities found in that system to the administrator, and makes no harm to that system, while a Black hat hacker does harm to that system and the hacks that system for his own purposes. Black Hat hacking is illegal while ethical hacking is not illegal. Many companies hire advanced ethical hackers to penetrate into their system and find the vulnerabilities.

Keep Your Data Safe: Safety From KeyLoggers

Suppose you have a program on your computer, whose job is to send a complete list of all the buttons you press on your keyboard every day to a person, without your knowledge. All day long, you are logging in to your email, you are doing online banking, going to different websites, buying something with your credit card, or more. All these information when you are giving, using your keyboard, it's just getting sent to another end of the world ... now you can understand that I'm talking about the keyloggers.

I have seen a facility in Kaspersky Internet Security 2011that they have given a module called Virtual Keyboard. Believe it, it's a hard job to write using it.

QFX Software has come up with a 'key scrambler' to help you to cope with this kind of pain. Let's see how it works;

Before going to see how 'key scrambler' works, let's know some key points;

Important Path: 

When you type something with your keyboard, those keys reach the specified application through the operating system. (Suppose you are giving your name and password to Mozilla Firefox).

Key Logger: 

The key logger is a type of mailwire that is created by cyber criminals to steal your important information, just when you type something with your keyboard. Key loggers steal your information just before they reach specific apps.

Now let's see how the Key Scrambler works;

Encryption used to prevent Keyloggers

As soon as you press any key on the keyboard, the 'Key Scrambler' software inside the Kernel encrypts it.

Then when you reach the Destination app, 'Key Scrambler' decrypts it again, so that you can show what you have given.

No matter what kind of logger they are, they will only see your information encrypted version.

If you want, you can download the key Scrambler software from here.
