Create a Classification using Proximity

You can identify sensitive data with text patterns using advanced patterns, dictionaries, and keywords in a classification. Use a proximity match in your classification to define how many characters can separate items in advanced patterns, dictionaries, and keywords and still trigger a match. If two items are found within the selected number of characters, it's a match. 

To create a classification using proximity:

  1. Go to Policy > DLP Policies > Classifications
  2. Click Actions > Create Classification
  3. Classification Name. Enter a name for this classification. For example, Proximity Match Classification. Enter an optional description to describe its use or purpose.
  4. Category. Select a Category from the list. 
  5. Conditions. For IF, for this example, select Proximity.

  6. Define your proximity classification criteria:

    • Proximity is less than <number> characters. Enter a number to specify how close the values must appear. The number of characters should be between 1 and not more than 99,999 characters.
      For Example: If you enter 20, the two values must appear within 20 characters of each other to trigger the classification criteria.
    • between: Select Criteria. Select two values to specify proximity for. The values can be a dictionary, an advanced pattern, or a keyword. Select one of the following:
      • Dictionary. Select from: 
        • is any of. To match any of the items. 
        • Then select one or more Dictionaries from the side panel. (To close the side panel, click X.)

    • and. The values again can be a dictionary, an advanced pattern, or a keyword.
    • and found at least <number> times. This is the match count. Enter a number to specify how many times the values must appear in proximity to each other to trigger the classification criteria. The number can be between 1 and 5000. 

NOTE: The proximity rule limit should be within 1 to 5000. If the proximity limit exceeds, the error message is displayed as an Invalid value.
