Computer security is the process of
preventing and detecting unauthorized use of your computer.
Prevention measures help you to stop unauthorized users
(also known as "intruders") from accessing any part of your

2AdvanceIT is concerned with three main areas;
- information should be available only to those who
rightfully have access to it.
- information should be modified only by those who are
authorized to do so.
Availability - information should be accessible to
those who need it when they need it.
These concepts apply to home Internet users just as much as
they would to any corporate or government network. In the
same way, you may want to keep the tasks you perform on your
computer confidential, whether it's tracking your
investments or sending email messages. Also, you should have
some assurance that the information you enter into your
computer remains intact and is available when you need it.
