Security Issues of P2P Networks

Abstract
P2P applications introduce a whole new series of security issues, security within the virtual P2P networks themselves and security with respect to the environments they ride on. P2P technology can undermine network security and can leave computing devices open to threats ranging from violations of intellectual property laws, virus ....etc

Security Issues in MANETs
Presented By:
Abhishek Seth 04329001
Abstract
Mobile Ad hoc Networks (MANET) has become an ex¬citing and important technology in recent years because of the rapid proliferation of wireless devices. A mo¬bile adhoc network consists of mobile nodes that can move freely in an open environment. Communicating nodes in a Mobile Adhoc Network usually seek the help ofother intermediate nodes to establish communication channels. In such an environment, malicious interme¬ ....etc

Introduction
A mobile ad hoc network (MANET), sometimes called a mobile mesh network, is a self-configuring network of mobile devices connected by wireless links.
Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic.
Such networks m ....etc

A Computational Grid is a collection of heterogeneous computers and resources spread across multiple administrative domains with the intent of providing users easy access to these resources. There are many ways to access the resources of a Computational Grid, each with unique security requirements and implications for both the resource user and the resource provider. A comprehensive set of Grid usage scenarios is presented and analyzed with regard to security requirements such as authentication, authorization, integrity, and confidentiality. Th ....etc

Router
Router is a device which extracts the destination address from the incoming packet and sends it to the destination through the optimal path. Directing data between portions of a network is the purpose of a router.

Routers operate at the ....etc

Security Issues in Mobile Ad hoc Networks
Mobile Ad hoc Networks (MANETs) - Overview
MANET is a self-configuring network of mobile nodes connected by wireless links—the union of which form an arbitrary topology
Individual nodes act as routers
- cooperate to forward both its own traffic as well as its neighbors traffic
Minimal configuration and quick deployment make ad hoc networks suitable for emergency situations like natural or human-induced disasters, military con ....etc
