Configuring the Dynamic Document Review (DDR) filtering threshold
Symantec Protection Engine compares the text on the requested Web pate to the DDR dictionaries that you activate for the content categories that are in the Deny Access list. Based on the results, Symantec Protection Engine determines whether to block or allow access to a site. Each occurrence of a word that is contained in an active dictionary receives a numerical score. Symantec Protection Engine keeps a total score for a given amount of text. If the total score exceeds the configured threshold, access to the site is blocked.
You can enable DDR filtering, and you can change the sensitivity of the DDR filtering for incoming and outgoing requests.
