摘要：In modern world, our entire life moves around Computers. Most of our tasks are dependent on the Computers, like Communication, Ticket Reservations, Researches, Printing, Education, etc. When we communicate with each other by using Computers through E Mails, a number of Computers are used for this purpose and the collection of these computers forms a network, which is called a Computer Network. As more and more peoples are going to be connected through the general network (INTERNET), the problem of security arises. Now a day, a number of security issues occur in networks which include Sniffing, Spoofing, Security Attacks, Malwares, Unauthorized Access, etc. This will create havoc for the users, who wants to communicate with each other through these networks. So, to make the communication between two users via the Computer Networks, we have to follow some security measures, which include using the Firewalls, Anti Malicious Software, Intrusion Detection Systems, Cryptography Techniques, etc. This paper is basically focused on how the communication between two users has been performed by using Computer Networks and how to make such a communication safe and secure.
