Shadowed Rules Report

Overview

The Shadowed Rules report identifies redundant rules based on shadowing information, including contextual attribution between the shadowing and shadowed rules. It lists all the shadowed and shadowing rules for each selected device.

This report enables you to:

• Eliminate unnecessary rules.

• Focus efforts to achieve network policy health in key domains.

Create a Shadowed Rules Report

Prerequisites

• In the Settings > General page, the administrator must configure the outgoing SMTP server and the remote repository.

Procedure

1. From the Create () menu, click Shadowed Rules.

   The Setup page for the report appears.

   

2. Complete the report fields:

   • General: Report name.

   • Domains and Devices: Select a domain and one or more devices or device groups.

   • Filters: Excludes rules based on filters. Select the check box and provide values for filter components.

     A filter definition excludes rules according to the value of the following components:

     Filter Component	Description	Example
     Source/Destination	Source and Destination	an IP (1.1.1.1), subnet (1.1.1.0/24), or any
     Service	Service	tcp:80
     Action
     Comment	Partial or full text from comments in the rule	Production environment
     Tag name (Palo Alto only)
     Source/Desitnation Device Zone

     In a single filter definition, the filter components are logically joined using the AND operator. In this example, a rule will be excluded if it has any in the source and 2.2.2.2 in the destination.

     

     You can create additional filter definitions. STRE treats the relation between filter definitions with an OR operator. In this example, a rule will be excluded if it has a source value of 1.1.1.1 or destination value of 2.2.2.2.

     • Calendar Month: Available only for Monthly frequencies. This is the second monthly scheduling option. Runs report on the 1st or 15th of the calendar month. Reports based on calendar months run automatically at midnight.
