NGFWs, or Next Generation Firewalls are the latest addition in the arena of firewall technology. The procedure involves the implementation of DPI or Deep Pocket Technology. This helps in the inspection of the payload of the content of your data packets. As a result, you can create a greater number of firewall rules.
Understand the devices
There are many devices to follow the firewalls. This happens on the basis of different types of devices, data, applications, and also users. The 1st generation firewall, which started in the 1980s, revolutionized the web world. After evolution with the 2nd and 3rd generation firewall, the NGFWs offer more sophisticated and comprehensive features, among other benefits.
Why is Upgradation needed?
There is a need for upgradation everywhere. As per the model of OSI or Open Systems Interconnection, there are as many as 7 layers of network communication. Starting from top to bottom, it involves Application, followed by Presentation, then Session, after that Transport, then Network, followed by Data-link, and finally Physical. Recurrent cyber-attacks are likely to target the vulnerabilities of just about any of the layers. To meet this issue, next generation firewall is helpful.
The Difference between the two
Conventional firewalls can handle only relatively simple activities. This might involve filtering packets or stateful inspection. They can operate no more than the 4th level of the OSI model. So, the possible threats on 5-7 do not have adequate protection exclusively through conventional firewalls. However, Contrastingly, NGFWs can filter network traffic up to level 7. The system takes the basic elements of conventional firewalls. Besides, they add more components that heighten security.
Understand the Benefits
It’s time to understand the benefits of multiple firewalls. By using Next-generation firewalls, you can enjoy better security than that of 3rd Generation Firewalls. The old version of Firewall has a lacuna of rules specific to applications. Moreover, it does not offer comprehensive malware protection and might not always block or detect any indication of unusual behavior. However, the NGFWs have the capacity to process updations for external networks of threat intelligence.
