What is a primary purpose of Data Loss Prevention?

The primary purpose of Data Loss Prevention (DLP) is to identify, monitor, and protect sensitive data from unauthorized access and sharing. Specifically, restricting sensitive document emailing involves the enforcement of policies that prevent users from unintentionally or maliciously sharing sensitive information through email. This is crucial for organizations that need to comply with regulations regarding data privacy, such as GDPR or HIPAA, which mandate that personal or sensitive information is not improperly disclosed to external parties.

In this context, while encryption, data backup, and monitoring network traffic are important aspects of an overall data security strategy, they serve different functionalities. Encrypting data ensures that it is protected while at rest or in transit, but it does not prevent the sharing of sensitive information altogether. Backing up data is essential for recovery purposes but does not actively prevent loss or unauthorized disclosure. Monitoring network traffic for anomalies is critical for detecting potential threats, yet it does not specifically focus on preventing sensitive data from being shared inappropriately. Therefore, restricting sensitive document emailing aligns directly with the goals of Data Loss Prevention by proactively safeguarding sensitive information from being sent outside the organization.
