Answer to Question 1

A

Answer to Question 2

The CIA triad includes confidentiality, integrity, and availability. Confidentiality is the assurance of data privacy. The data or transmitted message is encrypted so that it is readable only by the person for whom it is intended. The confidentiality function prevents unauthorized disclosure of information. Integrity is the assurance that data are accurate or that a message has not been altered. It means that stored data has not been modified without authorization; a message that was sent is the same message that was received. Availability is the assurance that access to data, the Web site, or other EC data service is timely, available, reliable, and restricted to authorized users.
