Abstract

Networking is a way of connecting geographically distributed devices so as to communicate and share resources such as printers, files etc. Nowadays, Networking is extensively used in banking sector, e–commerce, social networking sites, news groups, sharing of software, sharing of valuable information among others and so many more. The unauthorized access to these networks is restrained by the administrator who apply and use various provisions and policies which is termed as network securities. Network security refers to any activity designed to protect network. Network security is an extremely valuable and procreative amenity. A threat exists whenever the security is perceived to get breached and vulnerability likely to be exploited. To enhance and strengthen a safeguard mechanism in protecting information multiple layers of security are implemented in our algorithm instead of adopting a single layer which at times may fall through.
