Trying to Automate Palo Alto Firewall Objects/Rules Cleanup
In this blog post, we will walk you through how to clean up Palo Alto Firewall Objects and Rules using a simple Python script. The script is designed to search for a specific IP address or an entire subnet and remove any associated references.
The Problem
Have you ever found yourself in a situation where you've decommissioned a server or maybe even an entire subnet, and now you're faced with the task of cleaning up your firewall? If you're using Palo Alto, you probably know that you can't just remove an address object; you first need to eliminate all its references from address groups and rules.
This can become especially cumbersome if a single object is referenced in multiple places—you'll have to remove them one by one. Now, imagine having to do this for an entire subnet where multiple objects are involved. If this sounds familiar, read on to find out how to make this process easier using a simple Python Script.
If you are looking for a more sophisticated solution, feel free to check my other blog post on how to achieve this via the 'pan-os-php' library.
