Data Loss Prevention comes with a set of predefined
expressions. These expressions cannot be modified or deleted.
Data Loss Prevention verifies
these expressions using pattern matching and mathematical equations.
After Data Loss Prevention matches
potentially sensitive data with an expression, the data may also
undergo additional verification checks.
For a complete list of predefined expressions, see the Data Protection Lists
document at http://docs.trendmicro.com/en-us/enterprise/data-protection-reference-documents.aspx.
