  • Predefined—Use the predefined data patterns to scan files for social security and credit card numbers.
  • Regular Expression—Create custom data patterns using regular expressions.
  • File Properties—Scan files for specific file properties and values.

Shared
Select this option if you want the data pattern to be available to:
  • Every virtual system (vsys) on a multi-vsys firewall. If you clear this selection, the data pattern will be available only to the Virtual System selected in the Objects tab.
  • Every device group on Panorama. If you clear this selection, the data pattern will be available only to the Device Group selected in the Objects tab.
Disable override (Panorama only)
Select this option to prevent administrators from overriding the settings of this data pattern object in device groups that inherit the object. This selection is cleared by default, which means administrators can override the settings for any device group that inherits the object.
Pattern Type
Select the type of data pattern you want to create:
Predefined Pattern
Palo Alto Networks provides predefined data patterns to scan for certain types of information in files, for example, for credit card numbers or social security numbers. To configure data filtering based on a predefined pattern, Add a pattern and select the following:
  • Name—Select a predefined pattern to use to filter for sensitive data. When you pick a predefined pattern, the Description populates automatically.
  • Select the File Type in which you want to detect the predefined pattern.
Regular Expression
Add a custom data pattern. Give the pattern a descriptive Name, set the File Type you want to scan for the data pattern, and enter the regular expression that defines the Data Pattern.
For regular expression data pattern syntax details and examples, see:
File Properties
Build a data pattern to scan for file properties and the associated values. For example, Add a data pattern to filter for Microsoft Word documents and PDFs where the document title includes the words “sensitive”, “internal”, or “confidential”.
  • Give the data pattern a descriptive Name.
  • Select the File Type that you want to scan.
  • Select the File Property that you want to scan for a specific value.
  • Enter the Property Value for which you want to scan.
