What are firewalls and application gateways and the difference between them?

Question

Accepted Answer

Firewalls and application gateways are both security measures used to protect networks, but they differ in their approach.

Firewalls are network security systems that monitor and control incoming and outgoing network traffic based on predetermined security rules.
Application gateways, also known as application-level gateways or application layer firewalls, operate at the application layer of the OSI model and can inspect and filter traffic based on the specific application being used.
Firewalls are typically used to protect entire networks, while application gateways are used to protect specific applications or services.
Firewalls can be hardware or software-based, while application gateways are typically software-based.
Examples of firewalls include Cisco ASA, Fortinet FortiGate, and Palo Alto Networks Next-Generation Firewall, while examples of application gateways include Microsoft Forefront Threat Management Gateway and F5 Networks BIG-IP Application Security Manager.
