What is Information Security?

Information security means protecting information and information systems from unauthorized access, use, modification, or destruction. The terms information security, computer security, and information assurance are frequently used interchangeably.
These fields are interrelated and share the common goals of protecting the confidentiality, integrity, and availability of information.

Computer Security

With the introduction of the computer, the need for automated tools for protecting the files and other information stored on the computer became evident.
This is especially the case for a shared system as like the internet. Thus, computer security is the generic name for the collection of tools designed to protect data and to prevent hackers.
