CISA

Certified Information Systems Auditor (CISA) is an audit professional certification sponsored by the Information Systems Audit and Control Association (ISACA). Candidates for the certification must meet requirements set by ISACA.
Candidates for a CISA certification must pass the examination, agree to adhere to ISACA's Code of Professional Ethics, submit evidence of a minimum of five years of professional IS auditing, control, or security work, and abide by a program of continuing professional education.
It was established for the following reasons:
1)Develop and maintain a tool that could be used to evaluate an individuals' competency in conducting information system audits.
2)Provide a motivational tool for information systems auditors to maintain their skills, and monitor the success of the maintenance programs.
3)Provide criteria to help aid management in the selection of personnel and development.
The first CISA examination was administered in 1981, and registration numbers have grown each year. Over 60,000 candidates have earned the CISA designation.
I think CISA is definitely helpful especially for managers as it can help them choose the best resources.
