RBAC & Sarbanes-Oxley Compliance

The Sarbanes-Oxley Act establishes a set of requirements for financial systems, to deter fraud and increase corporate accountability. For information technology systems, regulators may need to know who used a system, when they logged in and out, what accesses or modifications were made to what files, and what authorizations were in effect. IT vendors responding to Sarbanes-Oxley requirements have adopted RBAC as central to compliance solutions because RBAC was designed to solve this type of problem.
