What is Next Generation Firewall?
With the advent of digital transformation, gravely accelerated by the pandemic, some aspects need closer attention. And that is the case for Cyber Security.
Inserted in this context are the firewalls solutions, with the goal to protect the network against intruders and to safeguard systems and data. Amongst those is the Next Generation Firewall.
So what differs from Traditional to Next-Generation Firewall?
The Next Generation Firewall, also known as NGFW, is a third generation firewall technology that can be implemented in any software or hardware to prevent advanced cyber attacks. It is able to detect and block such threats by applying safety policies in three levels: application, port and protocol.
In other words, the Next Generation has additional resources when compared with a traditional firewall, as it goes beyond the port/protocol adding complex rules based on application awareness.
With this technology for instance, professionals of cyber security can analyze if a download has some type of threat, like ransomware, backdoor, or any other malware, known or unknown.
The Next Generation firewall operates with a layer 7 application filtering in the IOS model, while older versions only reached the 4th, which is the transport layer.
What are the NGFW main functions?
As we mentioned, the Next Generation Firewall has some of the same functions as a traditional firewall, with some add-ins such as:
- Application awareness;
- Intrusion Prevention System (IPS);
- Deep Pack Inspection (DPI);
- High performance;
- External threat intelligence;
- Etc.
Why do I need a NGFW?
A common misconception is that native digital businesses are already secured by the cloud tools. That is not always the case as, even though the cloud environment may be well protected, the wider structure can be left unprotected, with the use of insecure devices or internet connection, for instance.
With that said, the best solution for your business depends on the size of your network and the level of security needed, but the NGFW is currently the most effective and sophisticated solution for cyber security in the cloud age. Do you want do know more about this? Send us a message.
