SET TASKS

ABC has several branch offices across Australia with about 60 mobile sales employees at each branch office. Each employee is provided with an iPad and smartphone as well as access permission to remotely read and upload data to the database server at their branch office. The chief information security officer (CISO) at ABC believes that the use of password and malicious software (malware) poses threat to the database at ABC. The CISO estimates that a successful malware attack will cost ABC $28,000 for hiring external security consultant, $15,000 for containment and cleaning and $50,000 due to losses of sales. In order to mitigate the password related threats, ABC's password management system automatically rejects passwords that are found in the dictionary, passwords that are not seven characters long and passwords that do not have at least one capital letter, one number and one special character. The password management system also lockouts after a three failed log-in attempts. To mitigate malware risks, the ABC management is planning to purchase an antimalware solution at a cost of $50,000. It is expected that the annualized loss expectancy will be reduced to $75,000 if the antimalware solution is deployed on ABC system.
