Why can’t I just plug in my firewall and forget about it?The PCI DSS requires that all firewalls should be configured properly to fit their business environment.
If your firewall isn’t set up, configured properly, and maintained, you’re not PCI compliant.Having a firewall running won’t do you any good if you don’t have any rules established for what the firewall should be filtering. You need to set up your firewall so it’s restricting network traffic to only those authorized to access it.

If a firewall isn't properly configured, you might as well not have one. In a recent data breach investigation, the organization had a fairly sophisticated security and IT system. However, two incorrectly written firewall rules (amongst 300 pages of firewall rules, with about 100 rules on every page) essentially negated the whole firewall, leaving the entire network exposed. It was through this vulnerability that the attacker accessed their network.
Your firewall is your first line of defense, so you should dedicate some time to make sure it’s set up correctly and functioning properly.

Why aren’t businesses configuring firewalls properly?Many businesses don’t realize that firewalls aren’t a quick plug-and-play solution. They don’t realize it takes more to configure the firewall to help with their business’s unique environment.
To ensure your firewall does what it’s supposed to, I recommend seeking the help of a third-party expert. This will prevent common mistakes and ensure everything is set up correctly.
