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 device, which can functions both as a 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.

- What is a firewall designed to guard against?Packet filtering is governed by a set of rules.arrow_forwardHow does HTTP Strict Transport Security Work?arrow_forwardIn what ways do firewalls function as described below? 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
- When a web client attempts to gain access to protected resources hosted by a web server, it is important to demonstrate the step-by-step implementation of native authentication and authorization services. What are the two most compelling arguments in favor of layered protocols and why should they be used? You need to provide specific examples to back up your claim.arrow_forwardNote that the TCP/IP protocol suite's transport stage is where reassembly and reordering of packets occurs. A firewall may function at the Internet or data layer level of abstraction. If a traffic stream is corrupted or removed, a stateful inspection firewall will be unable to learn anything about it.arrow_forwardNative authentication and authorization services are run step by step when a web client seeks access to protected resources on a web server.

- Do not forget that the TCP/IP protocol suite's transport stage is where reassembly and reordering of packets occurs.

What are the two strongest arguments for using layered protocols? Give examples to support your claims.arrow_forwardRemember that the TCP/IP protocol suite's transport step reassembles and reorders packets.
