An information system (IS) auditor has been asked to represent the internal audit department of hero rganization on a task force to define the requirements for a new branch automation project for Brown Bank, a community bank with 16 branches. This new system would handle deposit and loan information and other confidential customer information. The branches are located within the same geographic area, so the director of branch operations has suggested the use of a microwave radio system to provide connectivity due to its low cost of operation and the fact that it is a private network. The director has also strongly suggested that it would be preferable to provide each branch with a direct coaxial connection to the internet (using the local cable television provider) as a backup if the microwave system develops a fault. The direct internet connection would also be connected to a wireless access point at each branch to provide free wireless access to customers. The director also asked that each branch be provided with mail and application servers that the administrative manager of each branch would administer. The IS auditor was informed by the IT manager for the bank that the cable service provider will encrypt all traffic sent over the direct coaxial connection to the internet. Questions: a. In reviewing the information for the project, what would be the MOST important concern about the use of microwave radio systems of Bank Brown? Justify your answer in no more than five (5) sentences. b. Give at least one (1) best possible way to reduce the likelihood of business systems being successfully attacked from the public internet through the wireless network. Discuss your answeri n no more than five (5) sentences.
