Application-Level Gateway Firewall: A type of firewall that operates at the application layer of a network’s protocol stack. It filters incoming traffic to certain network services like FTP and Telnet servers and can inspect the actual content of the data packets, not just the source, destination, and port. This allows for a more thorough examination of the packet payload to detect malicious code or protocols, offering a higher level of security compared to other types of firewalls.
