Application gateway/proxy
a) How is an application-layer gateway (ALG) different from a firewall?
An application firewall protects an application for being penetrated by unwanted software. This unwanted software could be malicious and could do damage to one's computer.
An application firewall specifically monitors and filters traffic to and from an application, focusing on the application layer (Layer 7) of the OSI model, which allows it to inspect and control specific application-level protocols, such as HTTP or FTP. In contrast, a network firewall operates at lower layers (Layers 3-4) and primarily filters traffic based on IP addresses, ports, and protocols, providing broader network protection. While network firewalls safeguard the overall network perimeter, application firewalls offer more granular security by examining the data being transmitted and enforcing policies specific to individual applications.
The default Windows Firewall also monitors the Application layer
Firewall appliances are stand-alone, self contained combinations of computing hardware and software. A commercial grade firewall system consists of application software that is configured for the firewall application and run on a general-purpose computer.

A network firewall prevents unlawful network access to your website. However, most website attacks are perpetrated via ports that must be kept open to allow legitimate HTTP, HTTPS and FTP traffic. This is where an application firewall is important because it inspects all the traffic and separates legitimate traffic from attack attempts against your website.Companies as Incapsula.com provides every web application, regardless of its size, with enterprise-grade Web Application Firewall, ensuring that the website's web application is safe and available.A web application firewall helps protect a website from illegitimate traffic
