How is "data leakage" defined?

"Data leakage" is defined as the unauthorized transmission of data from within an organization to an external destination. This can occur through various means, such as emails, file transfers, or even physical departures where sensitive information is inadvertently or maliciously shared. The focus is on protecting sensitive information that should remain confidential and within the organization's control.

Effective data leakage prevention mechanisms are essential for organizations to maintain their security posture, as they help identify and mitigate the risks associated with unintentional or malicious data transfers. By understanding this definition, individuals can better appreciate the importance of implementing robust security measures to safeguard sensitive information and ensure compliance with relevant regulations.

The other options do not accurately describe data leakage; they either relate to data protection, auditing, or backup processes, which are vital but distinct aspects of data management and security.
