Which of the following is not one of the "five pillars of the lA model"Confidentiality Availability Assurance Integrity

To determine which option is not one of the "five pillars of the IA (Information Assurance) model," we first need to understand what the five pillars generally include. The five pillars of information assurance are:

1. Confidentiality - Ensuring that information is not disclosed to unauthorized individuals.
2. Integrity - Maintaining the accuracy and completeness of information.
3. Availability - Ensuring that authorized users have access to information and resources when needed.
4. Authentication - Verifying the identity of users or systems.
5. Non-repudiation - Ensuring that a person or entity cannot deny the validity of their signature on a document or the sending of a message.

Looking at the options provided, "Assurance" is not specifically recognized as one of the five pillars of the IA model. Instead, it is a broader term that may encompass certain elements of the pillars, but is not one of them.

Final Answer

Assurance is not one of the "five pillars of the IA model."
