Can you explain what is meant by Next Generation Firewall?

Next Generation Firewall (NGFW) is a modern type of firewall that, in addition to traditional packet filtering and access control functions, includes additional capabilities for more in-depth network protection. Key features of NGFW:

• Application Layer Filtering — analyzes traffic not only by IP and ports but also by applications and protocols.
• Integration with Intrusion Prevention Systems (IPS) — detects and blocks attacks in real-time.
• User and device control — identifies users and applies security policies based on them.
• Support for encrypted traffic — analyzes HTTPS and other encrypted protocols.
• Integration with threat management and signature database update systems.

Example: if a regular firewall blocks traffic on port 80, NGFW can allow access to certain web applications and block others, as well as detect attempts to inject malicious code into the traffic.
