What defines a data leak?

A data leak is primarily defined by the accidental exposure of sensitive information. This often occurs when data that should remain confidential is inadvertently accessed or disclosed without authorization. Key factors that contribute to data leaks include human error, poor data handling practices, or inadequate security measures that fail to protect sensitive information.

In this context, the essence of a data leak lies in the unintentional aspect of the exposure, distinguishing it from other data mishandlings that may involve intentional acts or security breaches. This understanding is crucial because it highlights the need for organizations to implement robust data governance and security measures to minimize the possibility of unintentional disclosures, thereby protecting sensitive information.

The other options encompass different concepts pertaining to data management and security but do not specifically capture the accidental nature that characterizes a data leak.
