Hacking is an endeavor to misuse a computer system or a private network. Basically, it is the unapproved access to or command over computers or computer networks for some unlawful reason. Hacking is to gain access to a unauthorized system.
for example, login into an unauthorized email account , is also an act of hacking that account.
Gaining access to a unauthorized remote computer , is hacking that computer.
There are large number of ways to hack into a system and the word hacking can refer to a number of things but the main concept is the same.
Types of Hackers
There are three main types of hackers.
- Black Hat Hackers
- White Hack Hackers
- Grey Hat Hackers
Black Hat Hackers
These people are the some bad people that use to hack systems illegally in order to steal money/information or to achieve their own illegal goals.
White Hack Hackers
These people are good people who use the same techniques used by the bad people/black hat hackers and they also hack into systems, but they hack into only those systems that they have permission to hack, in order to test the security of these systems.
Grey Hat Hackers
They’ll hack into any system, even if they don’t have permission to test the security of this system.
In case of Grey Hat Hackers, They do not steal money or information from any system they hacked, also they will not cause any damage to that system.No doubt what they do is illegal, because they test the systems for flaws, for which they do not have any permissions which is against the law.
Why should we learn hacking?
Hacking is an existing industry.There is a number of job opportunities for ethical hackers, who would be able to test the security of systems/websites to confirm that these systems are secure and safe to be used and these are not vulnerable to black hat hackers.
There is a big demand of ethical hackers in these days, because the amount of hacking attacks are increasing day by day. Almost every single day we can find a news about big systems and big companies are getting hacked. Recently Big tech company Uber got hacked and senstive information/data of millions of users were exposed to the open internet. Major Companies like Uber/OLA , Facebook/Instagram and Google/Bing, they hire hackers in order to try and hack into their systems and tell them where the weaknesses are, so that they can fix it.
They frequently run bug bounty programs, where they ask all the hackers available in the whole world, to go and try to hack into their websites, systems or their web applications and if anyone will able to do that, they will pay them a bounty for the bugs or issues that they find.
