Overview on Network Security and its Vulnerabilities

Abstract

In this paper, we talk about security issues and their current results in the versatile specially appointed system. Mobile ad hoc network can be defined as a collection of mobile nodes which can be useful for form a network without help existing network. Nodes in network act as host and router which is used for send the packets for other device. The nature of MANET are dynamic topology, node mobility, scalability, self organizing capability is lead the network. Many security threats that disturb the open and distributed communication development which is challenging task .We first break down the primary vulnerabilities in the portable mobile ad hoc networks, which have made it much simpler to experience the ill effects of assaults than the conventional wired system. At that point we talk about the security criteria of the portable mobile ad hoc network what more present the principle assault sorts that exist in it. At last we overview the current security answers for the portable specially appointed system.
