Program Plan Intro
Firewall:
A firewall is security software, which imposes a set of protocols to prevent specific types of data from moving among trusted and untrusted level of networks.
Application Layer proxy firewall:
It is a device, which can function both on proxy server and as a firewall. It is also denoted as “application firewall” or “reverse proxy”.
- It has been configured to execute special software, which act as a proxy for a package request.
Packet filtering firewall:
It is a network device from the types of firewall, which examines header of packets that transmits into a network and finds whether to drop it or forward it through next network based on its rules.

A packet filtering firewall may prevent malicious data from being downloaded. Packet-filtering firewalls either accept or reject data packets without giving any indication of their decision to the sender. The packet filter firewall inspects each data packet as it passes through the firewall. It's possible that packet-filtering firewalls will investigate the application layer.arrow_forward
