Screen capture protection rule does not work when opening multiple browser tabs
Technical Articles ID:   KB88967
Last Modified:  3/27/2019

Environment

McAfee Data Loss Prevention Endpoint (DLP Endpoint) 11.x,10.x

Problem

Screen capture protection rule does not work when opening multiple tabs in a browser with the following conditions configured in the rule:
 
[Condition]

and Application visible on screen: is one of the supported browsers.
and Source URL:  is any web URL (ALL)

[Exception]

and Application visible on screen: is one of the supported browsers.
and Source URL:  is one of the web URL (OR): https://www.xxxxx.com

Cause

Protection rules that allow URL-based definitions, such as, clipboard, printing, and screenshot, are designed to trigger for each open browser tab or window. Triggering occurs regardless of whether the browser tab or window is the active tab or window. When running multiple browser tabs or windows, one of them can have the protection rules enforced on it while the others do not.

Solution

The behavior is considered normal and DLP Endpoint is operating as intended.
