It does not browse the content of them packets, however , and this type of fire wall has a limited quality of protection.

Next generation firewalls (NGFWs) use heightened methods of filtering, including deep packet inspection. This type of inspection looks at more granular facts in every single packet including the packet payload, application protocols and which specific computer the box is looking to communicate with. This permits a fire wall to implement much more correct rules and stop malicious conversation. It also helps defend against attacks apply a single attacked computer to infect additional computers and create significant groups of the living dead to send a denial-of-service infiltration or perform other forms of malware.
