Network has become a very important aspect in the technology development because it has the biggest effect on the communication between people, exchange and share resources. Network is a group of computers and other devices connected together in order to allow information to be exchanged or shared between each other. Having a high level of security in any system in network has become the desire that most of people want to reach. Therefore, the intention of this paper is to explore the security Issues in mobile Ad-hoc network. The paper has been divided into five impotent sections. The first section discusses the weaknesses or vulnerabilities in mobile Ad-hoc network. The second section mentions the types of Attack in mobile Ad-hoc network. The third discusses the routing protocols in mobile Ad-hoc network. Fourth, discusses the goals security of mobile Ad-hoc network. Finally, the paper will offer security solutions for mobile Ad-hoc network which can provide a high performance security to mobile Ad-hoc network.

Excerpt from the Book
II. VULNERABILITIES OF THE MOBILE AD-HOC NETWORK
Before suggesting solutions for the security problems in mobile Ad-hoc network, it is necessary first to understand the vulnerabilities of this network and the difficulties that usually affect the performance of the mobile Ad-hoc network .To begin with, the heaviest elements of these weaknesses that actually minimize the efficiency of the Ad-hoc network are five in number. [4]
Firstly, the lack of secure boundaries in mobile Ad-hoc network is the major deficiency and simultaneously the biggest difference from the wired traditional network which has a solid line defense that can protect it from any attacks. As a matter of fact, this vulnerability in mobile Ad-hoc network is originated from the exact nature of the structure of mobile Ad hoc network .more specifically the nodes themselves are able to move inside the network and leave their places freely and haphazardly. On the other hand, to get access to the wired network means that the user needs to pass through different kind of protection walls such as firewall and gateway. Whereas in mobile Ad-hoc network, there is no need for adversary to gain the physical access to the network.

What are the core thematic areas covered in the document?
The study covers network vulnerabilities, types of malicious attacks, the role of various routing protocols, and established security goals like confidentiality and integrity.
What is the main objective of the research?
The main objective is to provide a comprehensive security framework for mobile Ad-hoc networks that can prevent unauthorized access and protect transmitted data.
Which scientific methodologies are employed?
The paper utilizes a comparative analysis of routing protocols and an evaluation of cryptographic encryption methods, including symmetric and public key techniques.
What topics are discussed in the main body?
The main body covers the inherent weaknesses of MANETs due to node mobility, a classification of attacks, details on routing mechanisms, and the application of digital certificates for authentication.
How can these findings be summarized by keywords?
The work is characterized by terms such as MANET, Network Security, Cryptography, Public Key Infrastructure, and Routing Protocols.
Why is node mobility considered a significant security risk?
Node mobility makes it difficult to maintain secure boundaries, as nodes frequently join and leave the network, preventing the implementation of fixed defensive perimeters like firewalls.
How do hybrid protocols differ from table-driven and demand protocols?
Hybrid protocols are designed to minimize control overhead by combining features of both proactive (table-driven) and reactive (on-demand) approaches, optimizing the discovery and maintenance of routes.
What role does the Key Distribution Center (KDC) play in network security?
The KDC facilitates secure communication by managing and distributing keys, which allows nodes to encrypt and decrypt data effectively.
