In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet.

Firewall can be implemented in many architectures. Conduct a study into the below firewall architectures, and explain each of them using diagrams.

1) Inside-Outside architecture

2) Three Home Architecture

3) Screened subnet architecture
