This report begins with a review of segregation of duties and sensitive access controls, and reasons why both subjects are often misunderstood by the audit and compliance community. It then offers an 11-step method for assessing business processes to find gaps where SoD and SA controls are necessary, establishing those controls, testing them for effectiveness, and documenting the process for outside review. The book includes (as appendices) several Excel spreadsheets giving examples of SoD and SA rules, and of capability listings to help assess control risks in key business processes.
