The next generation firewall (NGFW) is designed to address the requirements of better bandwidth management, deep packet inspection, and advanced inspection capabilities. Unlike traditional firewalls, NGFWs include additional features such as application awareness and control, integrated intrusion prevention, and cloud-delivered threat intelligence. They are capable of performing deeper inspections at Layer 7, identifying applications, and enforcing security policies more effectively. This makes them suitable for managing bandwidth efficiently, conducting deep packet inspection to prevent advanced threats, and performing thorough inspections for harmful activities1234.
Reference:
EC-Council's Certified Network Defender (CND) program outlines the importance of understanding and using IDS/IPS technologies and configuring optimum firewall solutions, which aligns with the capabilities of NGFWs5.
The CND course also emphasizes the protect, detect, respond, and predict approach to network security, which is a core feature of NGFWs6.
Additional information on NGFWs and their role in network security can be found in the detailed descriptions provided by various cybersecurity resources1234.
