ISCA Practical Case Laws

I am about to write my Chartered Accountancy Final in May 2011.

One of the subjects is "Information Systems Control and Audit" from which practical case laws may be asked from the following areas 

1 Systems Development Life Cycle(Programming & Design), 2 Types of System Control, 3 System Testing, 4 Business Continuity Planning(), 5 Enterprise Resource Planning, 6 Information Systems Auditing, 7 Information Systems Security Policy(Security)

I want to answer practical cases addressing the above topics so as to be prepared for my exams. So if anyone could help me in finding them I would be very grateful. Please remember I cannot answer cases relevant to MCA, but only CA

Thank you.
