Network security is a grouping of policy and necessities for make certain the protection of its possessions and the entire network interruption. It is evident in an execution of security rule and other computer network devices. The communication within the networks would deals with a range of hazards. Hence, the provision of protection system definitely needs within the communication channels. In existing scheme, the broadcasted information secured by many kind of Encryption Schemes and protect attacks by using Signature schemes to avoid intrusions during the transactions, but it may also leads in intrusion behaviors in some situation. Therefore, the priority based encoding encryption scheme is involved to prevent the intrusions within the channel allocation and in transactions using dynamic patterns. In some case, it may also cause security issues and make interruption in transactions, if any outflow of the encoding encryption patterns by the intruder. Thus, the objective of this paper is to construct a tough security strategy to prevent intrusions within the network transactions. In this paper, the Matrix Encoding and Decoding Scheme (MEDS) is included with the encryption scheme to build a hard-hitting intrusion protection system. This Scheme classifies the data packets in a matrix format and allows the encoding progression in a probabilistic manner to avoid the leakage of the security patterns. I. Introduction Computer network is collections of computing devices that are connected in assorted traditions in classify to commune and allocate resources. However, some connections are wireless, using radio waves or infrared signals. The generic term node or host refers to any device on a network. Data transfer rate: the speed with which data is moved from one place on a network to another. Data transfer rate is a key issue in computer networks. Computer networks have opened up an entire frontier in the world of computing called the client/server model. A machine and its software that serve as a special gateway to a network, protecting it from inappropriate access is known to be Firewall. Filters the network traffic that comes in, checking the validity of the messages as much as possible and perhaps denying some messages altogether and enforces an organization’s access control policy. Network security is intentional attacks on computing resources and networks persist for a number of reasons. Complexity of computer software and newly emerging hardware and software combinations make computer and the network susceptible to intrusion. It is difficult to thoroughly test an application for all possible intrusions. There are several security threats occurs in the communication channel of the networks such as denial of service, an intermediary for another attacks, unprotected window shares, email spoofing, packets sniffing, etc. Many businesses rely heavily on computers to operate critical business processes. Individuals are using computers for tasks that required discretion. Advent of Internet has provided a physical path of entry for every computer connected to the Internet. An always connected broadband connection is always vulnerable in this case providing security requires action on two fronts, namely the management and the technical fronts respectively. The management aspect relates to organizational policies and behavior that would address security threats and issues. The technical aspect relates to the implementation of hardware and software to secure access
