Computer Security
Computer security or Home Computer Security is the effort to
create a secure computing platform, designed so that agents
(users or programs) can only perform actions that have been
allowed. This involves specifying and implementing a
security policy.
Home Computer Security is a effort to make a secure
computing platform for home users.
The
actions in question can be reduced to operations of access,
modification and deletion. Computer security can be seen as
a subfield of security engineering, which looks at broader
security issues in addition to computer security.
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.
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.
We use computers for everything from banking and investing
to shopping and communicating with others through email or
chat programs. Although you may not consider your
communications "top secret," you probably do not want
strangers reading your email, using your computer to attack
other systems, sending forged email from your computer, or
examining personal information stored on your computer (such
as financial statements).
