Next-Generation Firewalls (NGFW) belong to the third generation of firewall technology. It combines the functionality of a traditional firewall with other networks and application firewalls using in-line deep packet inspection (DPI), advanced malware protection, and URL filtering.
NGFW generally has the following features:
These firewalls work better and faster than traditional firewalls, and they are better in controlling the traffic entering and exiting a network.
Traditionally, firewalls and intrusion prevention systems are separate devices. But NGFW integrates firewall and intrusion prevention system (IPS) capabilities into one device. This integration provides improved performance and accessibility.
Below are a few examples of NGFW devices:

Exercise 4 - Next-Generation IPS
Next-Generation Intrusion Prevention System(NGIPS) provides additional capabilities to secure the network from threats. It is used alongside firewalls to prevent any malicious attacks in the network. NGIPS is a security device that works with predefined signatures. These signatures are codes of known exploit. When a threat is discovered, its signature is added to the dictionary. In this exercise, you will learn about the NGIPS security device.
