Explanation:
Integrity refers to the ability to ensure that the data is not modified or tampered with.
Integrity means that data cannot be modified without authorization. Integrity is violated when an
employee accidentally or with malicious intent deletes important data files, when a computer virus
infects a computer, when an employee is able to modify his own salary in a payroll database,
when an unauthorized user vandalizes a Web site, when someone is able to cast a very large
of preventing disclosure of information to unauthorized individuals or systems. Breaches of
confidentiality take many forms. Permitting someone to look over your shoulder at your computer
screen while you have confidential data displayed on it could be a breach of confidentiality. If a
laptop computer containing sensitive information about a company’s employees is stolen or sold, it
ensuring that a party in a dispute cannot refuse to acknowledge, or refute the validity of a
statement or contract. As a service, it provides proof of the integrity and origin of data. Although
this concept can be applied to any transmission, including television and radio, by far the most
common application is in the verification and trust of signatures.
