Internet Security - Protect yourself in internet

When a computer connects to a network or internet and communicating with other computers, it is taking a risk of exposing data. Internet security involves the protection of a computer's Internet account and files from intrusion of an unsolicited user. Basic security measures involve protection by well selected passwords, change of file permissions and back up of computer's data.

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 computer system including data either it is private and sensitive or shared among group of users. Detection helps you to determine whether or not someone attempted to break into your system, if they were successful, and what they may have done to harm your system.

Three main areas of Information security
