Note on difference between the security objectives: Integrity and Availability:
In thinking through our discussion of the possible overlap in meaning and confusion between integrity and availability, the difference between the two becomes clear when we recognize that:
- Integrity of information implies trust in the validity, correctness, and authorized value of each datum (i.e. single data value) in information
- Availability of information implies physical/virtual ability to access and use information.
Thus a loss or breach of integrity may result in an incorrect decision or mistake due to data inaccuracy or reliance on a datum or data (i.e. plural of datum) lacking authoritative sanction. In contrast, a loss of availability of information may result in inability to perform one or more tasks. A breach of either integrity or availability may lead to adverse effect on organizational operations, organizational assets, or individuals. We will continue our discussion next week in class.
