A number of policy templates require customization of one or more classifiers in 
order to detect sensitive data. Customization includes creating a regular 
expression to search for identification numbers and a list of words and phrases 
that may consistently appear with the identification number. For example, adding 
a policy based on the FERPA (Family Educational Rights and Privacy Act) 
template requires creating a regular expression to match custom student ID 
numbers. If the ID numbers consistently appear with the phrase “Student ID,” 
such as “Student ID: 123-45-6789,” adding the phrase to the policy would 
improve content matching accuracy. For more information on required 
customization for DLP policies, see 

For policies that do not have a classifier, the scanning engine always returns a risk 
factor value of “75” when a message violates the policy. You may want to adjust 
the severity scale for such policies, depending on the type of DLP violations that 
may occur. See 

 for more information.
