Why you should worry about privacy?

  • You do not want anyone but you to control that system.
  • You do not want anyone but you to delete or add or edit anything in your disk without your consent
  • You do not want your system to become victim of hackers
  • You do not want them to identify you without asking permission
  • You do not want anyone to follow what you just did in that computer or where you’ve been

All of the above can be done by anyone without your consent or knowledge not only locally but remotely.  That is true if you will not learn how to maintain your privacy.
