Mobile Ad-hoc Network (MANET) is a wireless network model which is infrastructure-less and consists of mobile nodes. Since MANET does not have any centralized base station and is robust in nature, it is a major center of attraction. Due to the open nature, access to trusted authorities, the security in MANET poses a huge threat. Also energy constraint is another factor to be considered and thus, routing in MANET is a big challenge .In this paper we have discussed in depth about the various routing protocols in MANET and classify them. We have also discussed and compared their vulnerabilities in form of attacks, and classify these attacks. Brief descriptions of these attacks are given, mainly emphasizing on the network level attacks. Further we briefly review the existing secured MANET routing protocols to tackle these attacks and discuss their efficiency and shortcomings.
