ISACA (previously the Information Systems Audit and Control Association) is a world wide association of IS governance professionals. The association currently focuses on assurance, security, and governance and provides globally recognized certification in assurance (Certified Information Systems Auditor), security (Certified Information Security Manager), and governance (Certified in the Governance of Enterprise IT). The association is one of individual members, often the sole practitioner of information systems auditing, security, and/or governance in his or her company. The membership of the ISACA reflects a multiplicity of backgrounds and skills that make the information systems governance field challenging and dynamic. This chapter is run by volunteers who are ISACA members nominated through ISACA Annual General Meeting (AGM). ISACA members' participations in running the chapter are highly encouraged.
