How To Prevent Hacker Attacks

Hackers are always looking for a way to get into computers of other persons. It can be something as simple as phising confidential information (like credit card or bank account numbers) to complex hacking routines that use your computer as a repository for illegal content (like music or movies with copyright). 

Unfortunately there is no magical software to prevent hackers; and it will never exist. It doesn't matter how much money or resources you invest in designing the perfect system, someone will find the way to crack it. Even the biggest government agencies like NASA, CIA and NSA have been victims of hackers. And the same thing happens in the private sector with companies like Citigroup or Wal-Mart.
