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
