Abstract: Mobile ad hoc networks (MANET) are becoming increasingly popular wireless networking model in various areas of technology usage from every-day to specific military purposes. Security in ad hoc networks is a key concern in order to provide protected communication between mobile nodes in an unknown and heterogeneous environment. The main challenge of MANETs is their vulnerability to security attacks and how to operate securely and efficiently while preserving its own resources. This paper discusses the most common type of attack on MANET and their security challenges. There are a lot of existing solutions in this field which propose increasing of MANETs security by new protocol design, evaluate existing protocols and their abilities, propose new routing protocols, find solutions and prevention measures for existing attacks or improving specific characteristics of MANET such as the packet drop rate, the overhead, end-to-end packet delays, network throughput etc.This paper attempts to provide an overview of MANET security challenges.The paper finishing by presenting current and possible solutions as a problems requiring for further research in the future.

Key words: Ad Hoc Networks, MANET, Security.
