Data loss prevention (DLP) software detects potential data breaches/data exfiltration transmissions and prevents them by monitoring,[1] detecting and blocking sensitive data while in use (endpoint actions), in motion (network traffic), and at rest (data storage).[2]
The terms "data loss" and "data leak" are related and are often used interchangeably.[3] Data loss incidents turn into data leak incidents in cases where media containing sensitive information is lost and subsequently acquired by an unauthorized party. However, a data leak is possible without losing the data on the originating side. Other terms associated with data leakage prevention are information leak detection and prevention (ILDP), information leak prevention (ILP), content monitoring and filtering (CMF), information protection and control (IPC) and extrusion prevention system (EPS), as opposed to intrusion prevention system.
