Firewall vs proxy

What exactly is a firewall?

The firewall is the version specified by the router. All data packets entering or leaving the network are routed through the firewall, which determines whether they should be allowed or denied. All traffic must pass through the firewall, and only authorized traffic should be permitted. A powerful firewall is required.

What exactly is a proxy server?

A proxy server is a server that acts as a middleman or gateway between any device and the rest of the internet. A proxy receives and forwards connections requests before returning data for those requests. It uses the anonymous network id instead of the client actual IP address, so that the clients actual IP address cannot be revealed.

Firewall vs proxy:

  • Firewall can monitor and filter all the incoming and outgoing traffic on a given local network, while the proxy server connects an external client with a server to communiicate with each other.
  • Firewall blocks connectionsfrom unauthorised network, while the proxy server facilitates connection over network.
  • Firewall involve network and transport layer data, while the proxy work on appliction layer data.
  • Firewall filters data by monitoring IP packets that are traversed, while the proxy server fileters the client side request that are made to connect to the network.
  • Firewall exist as interface between a public and private network, while the proxy server can exist with public network on both sides.
  • Firewall is used to protect an internal network agaist attacks, while the proxy used for anonymity and to bypass restrictions.
  • The overhead generated in firewall is more as comapred to a proxy server, while the overhead generated in proxy server is less comapred to a firewall.
  • Firewall works on the packet level, proxy server work on application protocol level.
