CISA aspirants should be aware of the following aspects of change, configuration, and patch management processes for the exam.

Change Management Process

A change management process is used to change hardware, install software, and configure various network devices. It includes approval, testing, scheduling, and rollback arrangements.

When implementing a change, all relevant personnel should be informed and specific approval should be obtained from the relevant information asset owners.
