Data Loss Prevention

Definitions

1. Data Loss Prevention is technology and policy used to identify sensitive data and prevent unauthorized disclosure or movement. Security teams use it to enforce trust, reduce exposure, improve detection, or standardize secure operations in production environments. Its value depends on correct configuration, lifecycle management, and surrounding controls, because weak defaults, poor integration, or missing visibility can create gaps that attackers exploit.

   In plain English: Data Loss Prevention is a security concept or control that helps organizations protect systems, manage trust, and notice suspicious behavior before damage spreads.

   Example: "After the review, the security team rolled out Data Loss Prevention in the affected environment, documented the operating procedure, and verified through logs and test cases that the control reduced exposure without breaking normal administrative or user workflows."
