The narrow breadth Data Identifiers all have built-in validators that cannot be changed. In the case of keyword validators, that list is fixed. The Data Identifier keywords are evaluated before the optional validators. As a result, new keywords cannot be added to a Data Identifier with predefined values. The optional validator list can be used to reduce the number of keywords, not increase.
There are two possible courses of action:
Create a new Data Identifier
- Log into the DLP Enforce server
- Hover over Manage, then policies
- Select Data Identifier
- In the top left select Add Data Identifier
- Give the Date Identifier a name and description.
- In the patterns section, you can add one or more patterns separated by line breaks
- In the section titled Validators, you can select from a list of predefined validators or you can select custom script.
Change the breadth of the Data Identifier to either wide or medium
- Log into the DLP Enforce server
- Hover over Manage, then policies
- Select Policy List
- Find the policy that you need to change and click on it to open it.
- Open the rule that has your SSN date identifier in it.
- Under conditions, you will see an option for Breadth
- Select Medium
- Then find the "Also Match" at the bottom of the screen
- Select "Content Matches Keyword" from the drop-down.
- Select Match type and Key work Separator
- Add your list of keywords in the "Match any Keyword"
