Configuration management databases (CMDBs) are designed to hold information relating to all the components of an information system and provide a means to track configuration changes. This centralized repository allows organizations to monitor and control system changes, ensuring that all alterations are recorded and authorized. Auditing allows you to retrospectively analyze changes, but real-time alerts from a CMDB give you the ability to proactively respond to unauthorized changes. Periodic reviews are important, but they are not as effective as a CMDB for prevention. Using Jump Boxes, while valuable for secure management, does not directly help in tracking configuration changes.
