For each scenario, discuss the potential consequences and give a prevention technique.

a) A company has recently installed a new computer network. The operating philosophy adopted by the new network administrator was to establish an open system that would foster work group date to the network users. To accomplish this objective, the data administrator assigned employee access privileges to data based on department and functional affliation rather than specific tasks.

b) Mira is a system programmer who told he would be terminated in three weeks due to poor performance and was asked to conclude all of her projects during three week period. Two week later Mira created a logic bomb designed to get activated three months after her departure. Subsequently, the bomb destroyed hundreds of records in her previous employer's accounts receivable invoice file.
