Adding a key phrase classifier

Use the Patterns & Phrases > Key Phrase Properties page in the Data Security module of the Forcepoint Security Manager to create or edit a key phrase classifier.

The presence of a keyword or phrase (such as “top secret” or “Project X”) in content intended for an external recipient may indicate that classified information is being leaked. Forcepoint DLP makes it possible to block distribution of this information by defining a key phrase classifier. No other protection features, such as fingerprinting, are required.

To access the Key Phrase Properties page:

  • To create a new key phrase, New > Key Phrase in the toolbar for the Patterns & Phrases page.
  • To edit an existing key phrase, click the name of the key phrase in the list on the Patterns & Phrases page.

To define or update the key phrase:

  1. Enter a Name for the key phrase classifier.
  2. Enter a Description for this key phrase.
  3. Use the Phrase to search field to enter the key word or phrase that might indicate classified information, up to 255 characters. Key phrases are case-insensitive.

    Leading and trailing white spaces are ignored. If you need to use slashes, tabs, hyphens, underscores, or carriage returns, define a regular expression classifier rather than a key word classifier.

  4. Click OK.

Unlike dictionaries, key phrases also identify partial matches. For example, the key phrase “uri” reports a match for “security”.

You can have up to 100 key phrase classifiers.
