Popularly Used Security Protocols on All Layers of Network Communication

TCP/IP is used to provide network communication throughout the world. Now-a-days all organization are dependent on Internet and perform all sort of communication. Security controls exists for network communication at each layer of the TCP/IP Model. Even as this communication contains a lot of secret information which has to travel securely, more protection is required. Having developed and identified various security mechanisms for achieving network security, it is essential to decide where to apply them; both physically (at what location) and logically (at what layer of an architecture such as TCP/IP). Security professionals must understand the issues and risks associated with these transactions if they want to provide viable and scalable security solutions for Internet commerce. In this paper, we have discussed various security protocols existing in all layers and what are the best protocols which have to be implemented to perform any communication on the network.
