Part 3:

An enterprising group of entrepreneurs is starting a new data storage and retrieval business, SecureStore, Inc. For a fee, the new company will accept digitalized data (text and images, multimedia), and store it on hard drives until needed by the customer. Customer data will be transmitted to and from SecureStore over the Internet. SecureStore guarantees that the confidentiality and integrity of the datawill be maintained.

SecureStore also envisions certain information assurance requirements for their internal operations. Company employees will need to exchange confidential email, and will need a mechanism for verifying the integrity and originator of some email messages. Also, SecureStore intends a daily backup of all customer data to a remote facility via a leased line. They wish to do so as economically as possible, while ensuring the data's confidentiality and integrity.

SecureStore is interviewing candidates for the position of Chief Information Officer (CIO). They are asking candidates to describe briefly how they would satisfy SecureStore's requirements as stated above. How would a successful candidate respond?

First, distill the requirements from the above statements; once you have them then please address each requirement in a separate paragraph. Keep in mind that this business will be operating in the real world, which means please pay attention to economics. If you are unsure about the requirements, send them to me, I will comment on it.
