How Do I Create a Network Topology Diagram for Managing Firewalls?
Asked by

Hey everyone! I've recently been promoted to manage our Checkpoint firewalls, but I have to admit, I'm feeling a bit overwhelmed since I don't have much experience in this area, and the existing documentation is pretty much non-existent. I'm trying to create a comprehensive network diagram to better understand our network topology and I could use some advice. Are there any tools that can integrate with our Management Deployment System (MDS) to help with this diagram? Also, what initial steps should I take now that I'm in charge of the firewalls?

You might want to check out NetCrunch; they offer a free trial that can discover all the devices on your network and automatically generate a network topology diagram along with switch port mapping. It could save you a lot of time in the initial setup.

Just a heads up during your rule audits: be careful with something called 'Any.' It’s often the most used application by your users, but it can be confusing because ‘Any’ is also the name of a common location in your network. Make sure to clarify what you’re actually looking at!

Definitely take a closer look at your firewall rules and audit each one thoroughly. Make no assumptions about what they do. Understanding each rule is crucial for maintaining security and efficiency.
