In this seminar I am going to telling about ‘Firewall’ and ‘Proxy’ . Firewalls are network security tools that operate between the connection of an organization’s internal and the external network.
My reason to choose this domain for seminar is that every day we use internet too much time and we all know what firewall and proxy do but many user don’t know how it is work and how firewall protect our PC. But I think we should know about firewall because we are using it daily so I want to tell a basic introduction about Firewall and Proxy and Gain a better understanding of what a firewall is ?
The scope of this domain is in this days unautorized data access using internet called as “Hacking” is increasing contineuesly so to prevent this thing all servers and workstation using Firewall. In all OS, a firewall are installed to prevent attacks and control the flow of traffic into and out-of a network. Firewall is usually software running on a server or workstation.

Castles firstly appeared in the middle ages and they were concealed by high walls that were able to confront enemy armies and invaders. This concept of concealing an area of great interest finds great implementation in network security in a more modern setting with the use of firewalls.
