The banks are required to put in place a risk based internal audit (RBIA) system as part of their internal control framework that relies on a well-defined policy for internal audit, functional independence with sufficient standing and authority within the bank, effective channels of communication, adequate audit resources with sufficient professional competence, among others. Banks are expected to re-orient their approach, in line with the evolving best practices, as a part of their overall Governance and Internal Control framework. Banks are encouraged to adopt the International Internal Audit standards, like those issued by the Basel Committee on Banking Supervision (BCBS) and the Institute of Internal Auditors (IIA).
