As a Certified Information Systems Auditor (CISA), you'll perform business-critical functions by assessing your organization's IT and business systems to ensure they are monitored, controlled, and protected.

CISA is on the level of CISSP and CCIE in prestige - and in the way it distinguishes you from your peers. It's globally recognized within the IT industry and beyond, used by the US Department of Defense and others as a minimum requirement for many high-end security positions. And studies have found that having the CISA credential can increase your salary potential.

This manual consists of five chapters, one for each of the domains tested, and each chapter has two sections: the first defines the tasks and knowledge statements a CISA auditor is expected to know and the second contains the details for the domain. This Nugget course is based on the knowledge statements and will thoroughly define information that will be tested on the CISA exam.
