Classification Types

Content-Based Classification

Content-based classification parses and indexes the files’ textual content and searches for specific patterns, according to predefined sets of rules. These patterns can consist of keywords or keyword lists, complex regular expressions representing patterns such as patent numbers and source codes, and other user-defined parameters.

Composite Classification

It is sometimes required to use additional logic with data classification rules by combining the results of several classifications. The composite data classification rule is based on Data Access Security categories that are already classified by the Content and Behavioral rules.


A Data Classification policy cannot have both composite rules and other types of rules.
