Firewalls Questions
An application-layer firewall, also known as a proxy firewall, operates at the application layer of the network protocol stack. It differs from other types of firewalls, such as packet-filtering firewalls and stateful inspection firewalls, in that it can understand and interpret application-specific protocols and traffic. This allows it to make more informed decisions about whether to allow or block certain network traffic based on the content and context of the application data. Application-layer firewalls provide more granular control and can offer additional security features, such as content filtering and intrusion detection, compared to other types of firewalls.
