An information assurance plan for an organization should be formalised and approved policies of the Organization and have the following components: confidentiality, integrity, availability, accountability and non-repudiation.

The "need" must be aligned with an employee's job requirements and the Mission of the organization.

C. availability is this feature of information, ensuring that critical information and access exactly when and where it is needed and where it is required, so that decisions can be made. Computers and networks must be protected to ensure, the mission-critical data on page if necessary.
D. accountability refers to the idea of responsibility to an individual or a group of people for each part of the digital processing infrastructure. The information infrastructure is accessed each time, someone must be responsible for its safe and legitimate use. Otherwise, the system is open to serious security breaches.
E. non-repudiation is this component of the information assurance which guarantees that each party to a transaction to its results is bound. E-Commerce, would be, for example, impossible without provisions to ensure that a customer is actually a purchase made.
