mesh topology SecurityIn the last decade, the number of computers in custom has exploded. For quite some time now, computers have been a crucial element in how we entertain and educate ourselves, and most importantly, how we do business. It seems obvious in retrospect that a natural result of the explosive growth in computer use would be an even more explosive (although delayed) growth in the desire and need for computers to talk with each other. For quite some time, businesses were primarily interested in sharing data within an office or campus environment, this direct to the development of various protocols suited specifically to this task. Within the last five years, businesses have begun to need to share data across wide areas. This has prompted efforts to convert in worldwide LAN-based protocols into WAN-friendly protocols. The result has spawned an entire industry of consultants who know how to manipulate routers gateways and networks to force principally broadcast protoco ls across point-to-point links. Frequently the protocol of choice has been TCP/IP which is similarly the primary protocol run on the Internet. The emerging ubiquitous ness of TCP/IP allows companies to interconnect with each other via private networks as come up as through public networks. In todays world businesses, governments, and individuals, all are communicating with each other across the world. While existence is rapidly approaching this utopian picture, several relatively minor issues have changed status from low priority to extreme importance. Security is probably the most substantially known of these problems. When businesses send private data across the net, they place a high value on it getting to its destination intact and without being intercepted by someone other than the intended recipient. Individuals sending private communications obviously desire secure communications. Finally, connecting a system to a network can break the system itself up to attacks. If a system is compromised, the risk of data loss is high.It can be useful to break network security into two general classes Methods used to secure data as it transits a network Methods which regulate what packets may transit the network While both significantly affect the trading going to and from a site, their objectives are quite different. Transit SecurityCurrently, there are no systems in wide use... ... monitor all activity, and very blue-blooded to quickly control what gets in and out of a network.ConclusionThere are two basic types of network security, transit security and traffic regulation, which when unite can help guarantee that the right information is securely delivered to the right place. It should be apparent that there is also a need for ensuring that the hosts that receive the information will properly process it, this raises the entire specter of host security a wide area which varies tremendously for each type of system. With the growth in business use of the Inte rnet, network security is rapidly becoming crucial to the development of the Internet. Soon, security will be an integral part of our day-to-day use of the Internet and other networks.BIBLIOGRAPHYAvaya Inc.
