Computer security is a branch of Information Technology applied to both theoretical and actual computer systems. Computer security is a branch of Computer Science
that addresses enforcement of 'secure' behavior on the operation of
computers. The definition of 'secure' varies by application, and is
typically defined implicitly or explicitly by a Security Policy that addresses confidentiality, integrityavailability of electronic information that is processed by or stored on computer systems. and
The traditional approach is to create a trusted security kernel that
exploits special-purpose hardware mechanisms in the microprocessor to
constrain the operating system and the application programs to conform
to the security policy. These systems can isolate processes and data to
specifier domains and restrict access and privilegesof users. This approach avoids trusting most of the operating system and applications.
In addition to restricting actions to a secure subset, a secure
system should still permit authorized users to carry out legitimate and
useful tasks. It might be possible to secure a computer against misuse
using extreme measures:
