Definition
Data Loss Prevention (DLP) is a set of policies, processes and mechanisms used to detect and limit unauthorised disclosure, transfer or loss of data.
Human Explanation
DLP helps prevent confidential information from leaving an organisation accidentally or without authorisation.
Why it Matters
It reduces the Risk of information leakage, regulatory breaches and loss of high-value data.
Conceptual Boundary
DLP is not a single program or device. It is an approach combining Data Classification, security policies and control mechanisms.
Practical Perspective
Effective DLP requires the organisation to determine first which data matters and needs particular protection.
