Computer Security
Computer security is information security as applied to computers and
computer networks.
NIST Computer Security Handbook defines the term computer security as
“The protection afforded to an automated information system in order to
attain the applicable objectives of preserving the integrity, availability, and
confidentiality of information system resources (includes hardware,
software, firmware, information/ data, and telecommunications).”
The three important objectives of computer security are:
i) Confidentiality: Confidentiality can be in terms of data and privacy.
Data confidentiality means that the confidential information is not
disclosed to unauthorized individuals or not made available to public.
Privacy is about assuring individuals control or influence as what
information is to be collected and stored and by whom and to whom
that information is to be disclosed
