Where and when does network security comes in picture ?

Having said and written about Security and standards followed all across now it's the right time for me to start something real and interesting on this blog.

When does the Network Security or more precisely information security comes into picture. This seems to be a serious question.

Well lets say you are connected to internet and you want to visit any website may be google.com and you go on to IE or any browser and type google.com, now hereafter the moment you press enter and site lookup starts on internet, a complete information packet is formed ad this way we come to our first point of information making.

What is an IP Packet ?

Whenever an information is requested from web, it is broken into small blocks of packet to be sent across the web to the destination address and when all the blocks are received on the destination point all packets are reassembled and complete packet is formed.

These small blocks of information are called packets and hence all the packets are marked with source and destination ip address, hence the complete packet is known as IP PACKET.

How does an IP Packet Travels on Web ?

This is the most interesting aspect of web, where an IP Packet being originated from source are broken to pieces reaches the destination, reassembled again to complete the information.

Packet travel all across the globe follows the same standard sets of rules or are based on Basic OSI model which now in modern era are consolidated to 4 Layer standard now called TCP/IP Layer.
