The terms “data leak” and “data loss” are often used interchangeably. However, while data loss prevention focuses on the prevention of data being lost or stolen by someone outside of the organization, data leakage includes the risk of data flowing between your organization’s critical systems, such as human resources or CRM. When data is leaked, it is not necessarily lost.
Other associated terms include information leak prevention (ILP), information leak detection and prevention (ILDP), information protection and control (IPC), content monitoring and filtering (CMF), and extrusion prevention system (EPS).
