Ad-hoc networks are the collection of autonomous nodes where all the nodes are configured dynamically without any centralized management system. Mobile Adhoc NETworks (MANETs) are self-configuring network of mobile routers connected via a wireless link. However, the feature of decentralization and dynamic configuration of nodes makes MANETs vulnerable to various security attacks that are otherwise not so common in a wired network. For mitigation of these attacks, several secured routing protocols are being proposed till now. This paper provides the view of overall security breaches present in the Ad-hoc Networks till now and will discuss in brief about the several proposed secure routing protocols.
