Security issues

As the technology rises, the need for the its securty becomes more obvious because of all the problems that come along with it. I personally have suffered a lot because of the security issues with my PCs. One problem is the hackers or the people that try to break nto your computer online. But the problem I've suffered from comes from people getting on my PCs and getting my personal information from the PC physically. That is done by breaching the password in the begning of the computer and then they have access to all your information, from your pictures to your phone book and god knows what.There are many ways to prevent problems such as this, but there are many ways to break those tricks also therefore the more you try securing your data, the more you are vulnerable for security breaches
