MANET is a nature of wireless network without a rigid topology and consists of lay down of self-organized nodes. It is a lay down of mobile devices that can be communicate to each other without have cabled network. In communication purpose, they do not need help from network infrastructure. MANET (Mobile AdHoc Networks) is second-hand in many real world applications. Some of them consist of battlefield applications; liberate work applications, civilian applications like outdoor meeting, money transfers, and ad-hoc classrooms. There are many advantages of ad hoc networks. However, they also throw security challenges. The security attacks might be either internal or external attacks or both. The internal attacks are cause by collude nodes in the MANETs. The nodes are randomly, repeatedly and impulsively mobile. It is a dynamic, infrastructure less and decentralized network. The self-configuration ability of AdHoc networks constitutes an extensive variety of applications in tactical and common life. Security is foremost problem faced by the Ad Hoc networks due to its open environments. The intrinsic features of Mobile AdHoc networks make it susceptible to many security attacks which may completely or partially destroys and changes the information contents and functionality of the networks. This paper aims to provide better understanding of routing protocols, classification of routing protocols, security attacks, trust models and various types of trust model.
