An enterprising group of entrepreneurs is starting a new data storage and retrieval business, AcmeStore, 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 AcmeStore over the Internet. AcmeStore guarantees that the data’s confidentiality and integrity will be maintained.

AcmeStore also envisions some 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, AcmeStore 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.

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