Network Security Using Firewalls

As networks increase in size and complexity, security products are growing in sophistication and security threats are becoming more ingenious

Due to the ever increasing request for connectivity and inter-human communications, the Internet has known a booming growth in the last years. Even though it started as a way to connect Universities through expensive circuit switching methods, the following breakthroughs in networking protocols.

The whole philosophy of the Internet is based on the TCP/IP protocol. This protocol was designed as a set of overlaying layers, each with a complete and specific role. The four layers that compose the TCP/IP protocol.

The primary goal of the programmer when designing this application was to create a modular, efficient program, that occupies a minimum of resources when running.
