Hackers

As long as this is in the public mind that hackers are bad people who work by breaking into a computer system or network the Internet to steal data for its own benefit.Though not all hackers work for personal gain.

Those who work for private purposes is called black hat hackers or also sometimes called a cracker. His job is to attack a particular system and take advantage of it. There also are doing that only to be famous.
One example of this black hat hacker is break into a bank to steal data about customers and take over the accounts of the clients in order to steal money from customers. Another example is to break through into the system from the government for stole its data and leaked or sold to others.

Not all lay people know that there is also a good hacker. They are referred to as white hat hackers. They do not work for the benefit of himself. They usually work in the system which aims to keep the system can work well and have a good security that can not be infiltrated and compromised by unwanted people. They usually seek to identify a system in depth in order to know the weaknesses of the system and trying to fix it.
Examples of white hat hackers are analyzing the security of a website and find a weakness or a bug of the website, but not barging into the website. If there is a bug that is found it will be notified to the admin of the website in order to be patched.

Activities of these hackers give some benefits.
Of black hat hackers, no benefit is gained, but they motivate people working in the security network to work harder in order not to be compromised.

Of white hat hackers, we can get some benefits, there are:

• Securing systems and data, so can not be compromised and stolen by the black hat hackers.
• Trap the black hat hackers and catch them by trying to seek to know their location
• Save costs because the cost to maintain the security system is definitely much cheaper than having made the system from the beginning again.
• Makes the internet technology be better because they use their expertise to fix the weaknesses in the security system.

After learning that the hacker is divided into two type, good and evil hacker, I expected people do not believe anymore that the hacker was entirely a villain who work only for their personal gain.
