Real time transmission of voice over the Internet also known as Internet Telephony is sure to take a big leap into the modern world of technologies. Web phone lets two users to talk over the Internet for only the cost of connecting to a local server instead of calling over regular phone lines and paying long distance charges. The benefits of IP Telephony provides sufficient justification to evaluate the technology today to determine how an Internet dial tone can complement traditional PSTN services for the organization. Web phone promises free, ....etc

Internet Security
Protect your computer in 4 steps.

Step 1. Keep your firewall turned on
A firewall is a software program or piece of hardware that helps screen out hackers, viruses, and worms that try to reach your computer over the Internet.
A firewall helps protect your computer from hackers who might try to delete information, make your computer crash, or even steal personal information such as passwords or credit c ....etc

DCOM Technical Overview
Introduction
Microsoft Distributed COM (DCOM) extends the Component Object Model
(COM) to support communication among objects on different computers on
a LAN, a WAN, or even the Internet. With DCOM, your application can be
distributed at locations that make the most sense to your customer and
to the application.
Because DCOM is a seamless evolution of COM, the world's leading
component technology, you can take advantage of your existing
investment in COM-based applications, compo ....etc

INTRODUCTION
Security has prime importance in the field of networking. In a small closed environment, in which all systems are owned and operated by a single organization, the security risks are less. But in a more open environment, in which network connections to other machines are supported, we need a good authentication service to protect user information and resources housed at the server. For this purpose, Kerberos is used. Kerberos is an authentication service developed at Massachusetts Institute of Technology (MIT). ....etc

Flexible Rollback Recovery in
Dynamic Heterogeneous Grid Computing
Large applications executing on Grid or cluster architectures
consisting of hundreds or thousands of computational
nodes create problems with respect to reliability.node failures and the need for dynamic
configuration over extensive run-time maybe the sources of the problem. Theft Induced Checkpointing
and Systematic Event Logging methods for fault-tolerance are described here.

Authentication

User Authentication - Defined
The rapid spread of e-Business has necessitated the securing of transactions
Authentication is a fundamental security function. During authentication, credentials presented by an individual are validated and associated with the person's identity.This binding between credentials and identity is typically done for the purpose of granting (or denying) authorization to perform some restricted operation, like accessing secured files or executing sensitive transactions

A Novel Secure Communication Protocol for Ad Hoc networks
Abstract
An ad hoc network is a self organized entity with a number of mobile nodes without any centralized access point and also there is a topology control problem which leads to high power consumption and no security, while routing the packets between mobile hosts. Authentication is one of the important security requirements of a communication network. The common authentication schemes are not applicable in Ad hoc networks.
In this paper, we propose a s ....etc

CRYPTOGRAPHY AND NETWORK SECURITY
Abstract
Network security is a complicated subject, historically only tackled by
well-trained and experienced experts. However, as more and more people
become wired'', an increasing number of people need to understand the
basics of security in a networked world. This document was written with
the basic computer user and information systems manager in mind,
explaining the concepts needed to read through the hype in the
marketplace and understand risks and how to deal ....etc

Kerberos

Kerberos (pronounced / k rb r s/) is a computer network authentication protocol, which allows nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Its designers aimed primarily at a client server model, and it provides mutual authentication both the user and the server verify each other's identity. Kerberos protocol messages are protected against eavesdropping and replay attacks.
Kerberos builds on symmetric key cryptography and requires a trusted third party, and ....etc
