Composite Rule

A composite classification rule lets you combine several rules together to form a more complex criterion. This can include content and behavioral type rules, and is defined by category.

• The data classification matches content or behavioral patterns to rules, and assign categories to resources according to these rules.

• After running data classification, composite rules use combinations of categories to define complex combinations of simple rules

Examples:

You can combine Personal Identification Information (PII) in conjunction with health-related information (ICD), to define a rule to identify Personal Health Information (PHI).

or

You can create a rule to list files that have at least two out of one list of categories, and must contain another specific category.

or

Identify all resources that would be defined by rules that belong to category X.

To define a composite classification rule, select one or more categories, and the created rule will be triggered for any existing rules within the selected categories.

In the first example above, if we define a rule as follows:

Contain at least 2 of  PII, ICD

This will add all business resources that fill any of the rules in PII category, and any of the rules in ICD category.

• The value column allows selecting one or more categories from the category repository.

Triggering the Composite Rules

• Composite rule tasks are trigger after each data classification task, and evaluate results from that application only.

• The Composite rule runs after of all content and behavioral rules, as it is based on their results.

• If you change a composite rule, this change will take effect only when a new classification task is executed, and triggers the composite rule.

• This task can not be scheduled.
