Application, Network Layer, Proxy all protect us on the Internet to create a Layer as a firewall. In this article, I Explain what does proxy means, What is the Network layer, and the Application Layer.

What does proxy mean?


A proxy server act as a gateway between the User and the internet. It’s an intermediary server separating end users from the websites they browse. A Proxy device may act as a firewall by responding to input packets(connection request) in the manner of an application, whilst blocking other packets.

However, Proxies make tampering with an internal system from the external network more difficult. Misuse of one internal system would not necessarily cause a security breach exploitable from outside the firewall. Conversely, intruders may hijack a publicly reachable system to other internal machines. While the use of internal address spaces enhances security, crackers may still employ methods such as IP spoofing to attempt to pass packets to the target network.

What is Network Layer?


Network layer firewalls operate at a low level of the TCP/IP Protocol stack as IP-packet filters, not allowing packets to pass through the firewall. The firewall administrator may define the rules, or built-in rules may apply as in some inflexible firewall systems.

A more permissive setup could allow any packet to pass the filter. As long as it does not match one or more “negative rules”, or “deny rules”. Today network firewalls are built into most computer operating systems and network appliances.

Modern firewalls can filter traffic based on many packet attributes like source IP address, Source port, destination IP address, destination services like WWW or FTP. They can filter based on protocols, TTL values, netblock of the originator, the domain name of the source, and many other Attributes.

What is the Application Layer?


Application layer firewall works on the application level of the TCP/IP stack and may intercept all packets from an application. In other words, application firewalls can prevent all unwanted outside traffic from reaching protected machines.

However inspecting all packets for improper content, firewalls can even prevent the spread of viruses. In principle, however, this becomes so complex and so difficult to attempt. That comprehensive firewall design does not generally attempt this approach.


I hope you get the all information about the Proxy, What is the Network layer, and the Application Layer. If you like this article, you can share and comment. So that we too have a chance to learn something from your ideas and improve something.🙂

  • Full-Form of FDDI: Fiber Distributed Data Interface.

FDDI is a network protocol. Which is used primarily to interconnect two or more local area networks, often over large distances. The access method used by FDDI involves token-passing. FDDI uses a dual-ring physical topology. Transmission normally occurs on one of the rings; however, if a break occurs. So, the system keeps information moving by automatically using portions of the second ring to create a new complete ring. A major advantage of FDDI is Speed. It Operates over fiber optic cable at 100 Mbps.

It’s working by transmitting all data in small packets of a fixed size; Whereas, other protocols transfer variable-length packets. Asynchronous Transfer Mode supports a variety of media such as video, CD-quality audio, and imaging. ATM employs a star topology, which can work with fiber optic as well as twisted pair cable.

Asynchronous Transfer Mode is most often used to interconnect two or more local area networks. It is also frequently used by Internet Service providers to utilize speed access to the Internet for their clients. However, as ATM technology becomes more cost-effective, it will provide another solution for constructing faster local area networks.
