Layer 3 vs Layer 7 Firewalls: What’s the Difference?

Today, there are two primary strategies for monitoring, passing, and removing data as it passes through a firewall. Categorized into Layer 3 (Network Firewalls), and Layer 7 (Application Firewalls), these firewall configurations work at different transportation layers to determine what data is permissible to enter a given network.

Layer 3 Firewalls or the Network Firewall is designed to permit data transmission based on IP Address, port number, and service protocols. This firewall protocol is designed to accept traffic from certain IPs known as whitelisting and blocking other IPs known as blacklisting.

Layer 7 Firewalls or Application Firewalls permit data transmission through the firewall based on the application that is sending that data. For example, Layer 7 Firewalls may permit communication via a deemed safe application and deny application communication such as SQL injections.

As organizations look to maximize their network's security, it's often both the use of Layer 3 and Layer 7 Firewalls working in tandem that mitigate malicious attacks in the most effective manner.
