This document discusses security attacks in mobile ad-hoc networks (MANETs). It begins by defining MANETs as decentralized wireless networks composed of mobile nodes that communicate in a peer-to-peer fashion without fixed infrastructure. It notes that MANETs are vulnerable to both passive and active attacks. Passive attacks target confidentiality by snooping data, while active attacks disrupt normal operation by modifying, injecting, or dropping packets. Several specific active attacks are described, including black hole attacks, wormhole attacks, and routing table poisoning attacks. The document aims to identify security objectives, potential threats, and vulnerabilities in order to analyze attacks on MANETs.

- 2. Mobile Ad-Hoc Network Mobile Ad-Hoc Network is collection of mobile nodes which forms temporary network. In Mobile Ad-Hoc Network node communicate in peer to peer fashion. Nodes in MANET play both role of router and terminal, It is decentralized type of Wireless network. It is self organizing network without need of fixed network infrastructure and hence have dynamic network topology.
- 3. Mobile Ad-Hoc Network Communication between nodes in Mobile Ad-Hoc Network network via radio communication. Mobile Ad-Hoc Network supports anytime and anywhere. In general routes between nodes in an Mobile ad-hoc network may include multiple hops and call such network as multi-hop Mobile ad-hoc network. It reduced Administrative cost.
- 4. Application of MANET Mobile Ad-Hoc Network can increase mobility and flexibility, as Mobile ad-hoc networks can be brought up and torn down in a very short time. Mobile Ad-Hoc Network can be more economical in some case, as they eliminate fixed infrastructure costs and reduces power consumption at mobile nodes. Mobile Ad-Hoc network can be more robust then conventional wireless network because of their non-hierarchical distributed control and management mechanisms.
- 5. Vulnerability of MANET Dynamic Topology Wireless Links Cooperativeness Lack of clear line of defence Limited resources
- 6. Threat Model Identify the Security Objectives Identify the application overview Decompose Application Identify Threat Identify Vulnerability
- 7. Attacks on Mobile Ad-Hoc Network Attacks on Mobile ad-hoc network can be classified as active attacks or passive attacks. depending on normal operation of network disrupted or not. Passive Attack Passive attacks is difficult to detect because of this attacks normal operation of network is not affected. This attack target confidentiality attribute of the system. Attacker snoops the data exchanged in network without altering it.
- 8. Attacks on Mobile Ad-Hoc Network Active Attack In active attacks the intruders can modify the packet,inject the packets, drops the packets. It may disrupts the normal operation of the network. It confuses routing procedure and degrades network performance.
- 9. Attacks on Ad-Hoc Network Active Attack is classified as External Attack and Internal Attack. External Attack Carried out by nodes that do not belong to the domain of the network. Such attacks can be defended by using source an Authentication, firewalls and encryption. Internal Attack Internal Attacks are from Compromised nodes which are actually part of network.
