Symantec Data Loss Prevention supports metadata detection for servers and endpoints, the latter as of version 11.5. Symantec Data Loss Prevention provides a utility program called
filter that you should always use to verify file format metadata support. Using this utility helps you determine the metadata the system extracts for a specific file format. Once you have verified metadata extraction for the desired file format or formats, you can enable metadata extraction and implement policies to detect file format metadata.
Refer to the document "Metadata Detection Considerations" that is attached to this article. This document describes how to use the
filter utility to verify metadata extraction, how to enable metadata detection for server and endpoint, and what to consider when implementing metadata detection.
