What is a configuration drift?

Configuration drift refers to the gradual deviation of a device's configuration from its intended, approved state over time. This phenomenon often occurs when unauthorized or unintended updates are applied to a device, leading to inconsistencies between the current configuration and the baseline or desired configuration. As systems evolve, especially in dynamic environments where multiple users or automated processes may make changes, it's common for these alterations to go untracked or unnoticed. Recognizing configuration drift is crucial for maintaining system integrity, security, and compliance, as it can introduce vulnerabilities or unforeseen behaviors in the device's operations.

In contrast, the other options relate to different aspects of configuration management but do not accurately define configuration drift. Standardizing device configurations ensures consistency across devices, automating system provisioning streamlines the deployment process, and creating backups of configurations is focused on recovery, not on the gradual changes that represent drift. Thus, the focus on unauthorized updates as the root cause of drift makes the selected answer the most relevant.
