Answer:
The correct answer is d. Repudiation.
Repudiation is not considered an essential characteristic of Information Security in the cloud. The essential characteristics of Information Security in the cloud are:
a. Availability: Ensuring that information and resources are accessible and usable by authorized users whenever they are needed.
b. Confidentiality: Protecting sensitive information from unauthorized access and ensuring that only authorized individuals can access and view the data.
c. Integrity: Maintaining the accuracy, consistency, and trustworthiness of data throughout its lifecycle, preventing unauthorized modifications or tampering.
These three characteristics are commonly known as the CIA triad (Confidentiality, Integrity, Availability) and are fundamental principles in information security. Repudiation, on the other hand, refers to the ability to prevent individuals from denying their actions or transactions, and it is not typically considered an essential characteristic of information security in the cloud.
