For this example, you might create a DLP policy that uses the HIPAA and HITECH template. This 
template includes the Patient Identification Numbers content matching classifier, which you can 
customize to detect a patient’s identification number. To detect numbers in the pattern of 123-CL456789, 
you would enter the regular expression 

[0-9]{3}\-[A-Z]{2}[0-9]{6}

 for the classifier. Enter “Patient 

ID” for a related phrase. Finish creating the policy and enable it in an outgoing mail policy. Submit and 
commit your changes. Now, if the policy detects the number pattern in an outgoing message with the 
phrase “Patient ID” in close proximity to the number pattern, the DLP policy returns a DLP violation.

Many of the predefined DLP policy templates include content matching classifiers from RSA. Some of 
these classifiers require customization in order to identify the patterns that are used for data in your 
organization. 

If you create a custom DLP policy, you can choose a predefined classifier or create one of your own.
