Why is it necessary to define policy elements? Discuss the terms confidentiality, integrity, and availability as they relate to information systems. Why are they important?

First, it is important to know the definition of policy and its relevance to society and organizations.

Politics is the science of organization, direction and administration, linked to government, the state and public administration, with the aim of guiding the administration and promoting the public good. Therefore in every act of managing, whether in the fields of public or private administration, there will be policies for the direction of society and business.

Public policies are composed of 4 main elements: government involvement, perception of a problem, definition of an objective and definition of an action process.

Integrity corresponds to preserving the reliability, accuracy and consistency of information, in politics we can relate how the protection of information change by unauthorized persons and the design of policies that integrate and benefit the whole society.
