CISA (Certified Information Systems Auditor) is an ISACA certification for IT audit, control, and assurance professionals. It validates the ability to assess and audit an organization's information systems, controls, and governance.
What it means
ISACA's credentialing page lists CISA among its certifications and provides a free exam content outline plus a free practice quiz; review manuals and courses are paid. CISA is oriented toward auditing and assurance work — evaluating IT systems, controls, and processes — rather than hands-on security engineering.
