It covers five key domains: the process of auditing information systems and governance, the acquisition, development, and implementation of information systems, the delivery and support of IT services, the protection of information assets and risk management, and the concepts and practices of business continuity and disaster recovery. Each domain delves into specific topics, such as governance and management control programs, IT project management, service level management, information security policies and procedures, business impact analysis, and disaster recovery planning. Candidates must demonstrate their knowledge and skills in these areas to pass the exam and obtain the prestigious CISA certification. By understanding the exam's structure and content, aspiring auditors can effectively prepare and showcase their expertise in information systems auditing.
