What is hacking?

The word 'hacking' has several meanings, but in the context of ICT, which means breaking into computer systems.

Who are hackers?

Hackers (hackers) in the context of computer security refers to computer hackers involved in computer security and able to exploit the system or enter without permission through skills, tactics and detailed knowledge.

In common usage, "hacker" refers to a black hat hacker (malicious or criminal hacker). There are also ethical hackers (commonly called white hat) and hackers are ambiguous position (gray cap).

Why do hackers hacking?

Hackers may break into the system because of curiosity or to test the extent of their ability to overcome a defense system. But, mostly they invaded to access data that has a value.

For example, if a hacker enters your computer and steal financial information like your credit card numbers, or passwords to your bank account, they can use the information to make a purchase.

If a lot of information about you is stolen, hackers can use this to impersonate you on-line. They may apply for a new credit card, take a bank loan, buy a car, etc.. All in your name. This is known as identity theft.

Are computers can be protected from Hacking?

Just like in the real world, there is no guaranteed way to stop someone from intruding into a building (you can make it very difficult, but every security system has flaws), however, you can make it quite difficult to move and switch to hackers an easier target.

You should:

  • Use strong passwords to protect your user login account
  • Never disclose your password to anyone login
  • Put a firewall between your computer and any network
  • Disconnect from the network when you are not using them
  • Encrypt any sensitive information (just in case they get in)
