Despite this, attacks are increasingly targeting the higher layers.

Historically, perpetrators have focused their efforts on vulnerabilities in the lower 4 layers. Cyber attacks can target weaknesses in any of these 7 layers. The differences between next-gen firewalls and traditional firewallsĪccording to the Open Systems Interconnection (OSI) model, there are 7 tiers of network communication from top to bottom: Application, Presentation, Session, Transport, Network, Data-link, and Physical. Perhaps the best way to understand next-gen firewalls is to compare them to traditional firewalls. Read more about the history of firewalls here. Surpassing the following second and third generations, next-gen firewalls are today's more comprehensive and secure type of firewall. These first-generation firewalls played a crucial role in early cyber security, and have served as a great foundation for more advanced technology. Firewalls have been around since the 1980s. This allows users to create more granular firewall rules based on specific types of data, applications, devices, and users. NGFWs use something called deep packet inspection (DPI) to inspect the content (payload) of data packets. Next generation firewalls (NGFWs) are the newest generation of firewall technology.

What is a next-generation firewall (NGFW)? Read on to learn more about what a next-generation firewall is, what they do, Sangfor’s own NGFW, and much more. This article will cover the ins and outs of next-generation firewalls. This is where the next-generation firewall (NGFW) comes in. Traditional firewalls may have once been ample to do this, but newer and more dangerous threats require a more advanced approach.

Rather, it requires a multi-faceted approach focusing on all different aspects of network communication. For organizations, it is paramount to keep sensitive business data and operating systems secure. Cyber security and the act of defending your business's digital presence is not a singular and straightforward process.
