Abstract: Computer networks were primarily utilized by university researches for causation email, and by company workers for sharing printers. Beneath these conditions, security failed to get plenty of attention. But now, as many normal voters’ are victimization networks for banking, shopping, and filing their tax returns, network security is looming on the horizon as a doubtless huge drawback. Within the following sections, we are going to study network security from many angles, show various pitfalls, and protocols for creating networks safer. Network security issues are often divided roughly into four tangled areas: secrecy, authentication, Nonrepudiation, and integrity management. Secrecy must do with keeping data out of hands of approved users. This is often what typically involves mind once folks believe network security. Authentication deals with deciding who you're reprimand before revealing sensitive data or getting in a dealings. In the network layers firewalls are put in to stay packets in or keep packets out. Within the transport layer entire connections are often encrypted, end-to-end, that is, method to method. To tackle these issues, the solutions should be within the application layer, that is why there are being studied during this paper. Network security is turning into a lot of and a lot of crucial because the volume of knowledge being changed on the web will increase. once folks use the web, they need bound expectations. They expect confidentiality and therefore the information integrity. they need to be ready to establish the sender of a message. they need to be ready to prove that a message has indeed sent by an exact sender though the sender denies it.
