What differentiates a Next Generation Firewall (NGFW) from a traditional firewall?

1. It can only filter based on port numbers

2. It has no application management capabilities

3. It can manage applications and apply policies

4. It is less secure than traditional firewalls

The correct answer is: It can manage applications and apply policies

Next Generation Firewalls (NGFW) represent a significant advancement over traditional firewalls, primarily due to their ability to manage applications and apply security policies at a much higher level. Unlike traditional firewalls, which typically focus on filtering traffic based solely on port numbers and IP addresses, NGFWs integrate advanced features such as deep packet inspection, intrusion prevention systems, and application awareness. By incorporating application management capabilities, NGFWs can identify and control applications regardless of the port used, allowing organizations to enforce granular security policies. This is crucial in today's environment where applications often operate over non-standard ports, and threats can be disguised as legitimate traffic. In essence, the ability to recognize applications and enforce specific security policies enhances the overall security posture of a network, making NGFWs a critical component in modern cybersecurity strategies.
