Solved Step by step explanation- What is the primary value of a firewall

On the other hand, an application layer proxy firewall, also known as an application firewall or proxy firewall, operates at the application layer (Layer 7) of the OSI model. It provides more advanced security features by inspecting the contents of the network traffic, including the application data. Rather than simply looking at packet headers, an application layer proxy firewall understands the application protocols being used, such as HTTP, FTP, or SMTP.

The key difference is that an application layer proxy firewall acts as an intermediary between clients and servers. It receives requests from clients, validates and interprets them, and establishes separate connections with the intended servers on behalf of the clients. It inspects the entire communication, including the data payload, and can make more informed decisions about allowing or blocking traffic based on application-specific rules. This level of inspection provides better protection against application-level attacks and gives administrators more control over the network traffic.

Generally, it is faster and more efficient than an application layer proxy firewall because it focuses on packet header information.

Provides basic filtering capabilities but lacks advanced inspection of application layer protocols and data payloads.

Acts as an intermediary between clients and servers, establishing separate connections on behalf of the clients.

Inspects the entire communication, including application data payloads, to make more informed decisions.
