Configure Firewall Credentials to Fetch Configuration and Rules
In a Firewall device, there could be numerous rules/access-list defined to secure the network from external attacks. Out of the rules/access-list configured, there could be certain rules which would be most used and certain which are least used or never used. Firewall Analyzer captures the most used rules in the Top Used Rules as they would be available in the logs generated by Firewall. But, to get the Unused Rules, one needs to configure the Firewall Analyzer to fetch the complete rules from the device. Once, Firewall Analyzer fetches the complete rules configured in the Firewall, it can provide the Unused Rules view.
To view Unused Firewall Rules, configure the Firewall Analyzer by following the steps given below:
- In the Firewall Analyzer web client, select the Settings tab.
- In Settings screen, select the Firewall > Firewall Server > Device Rule link. Device Rule Info page appears.
