As there is a rapid increase in computer application of mobile and wireless network has changed the features of network security. Nowadays, there is an increase in internet attack and some fraudulent acts on companies and also on some individual networks. The way of protecting the computer networks are firewalls and security encryption are not sufficient and effective. Network security has become very important to personal computer users, organizations, and the military. In this paper RC4 based encryption algorithmic rule is pre-owned to secure Email communications. With the advent of the internet, security became a major concern and the history of security allows a better understanding of the emergence of security technology. Due to rapid requirement of computer's in business and other organizations many networks has been established. Nowadays, attacks on computer networks has increased to a great extend. So, there is a need of some methods for developing new mechanisms to protect wireless networks and mobile applications. This paper will be very important and useful for the network security. As there are many types of attacks which can be penetrated in our networks or edge devices. In this paper we would analyze different available mechanism to protect our network. Inside the day to day life people constantly uses communication tools that are e-mail promotional, instant communicating, social networking, search engines, bookmarking systems, affiliate systems, print media and direct mail. The encryption and decryption techniques are configured to manage with this security interval.
