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

The Semantic Grid refers to an approach to Grid computing in which information, computing resources and services are described using the semantic data model. In this model the data and metadata are expressed through facts (small sentences). Therefore it becomes directly understandable for humans. This makes it easier for resources to be discovered and joined up automatically, which helps bring resources together to create virtual organizations. The descriptions constitute metadata and are typically represented using the technologies of the Sema ....etc

High performance and data-intensive computing and networking technology has become a vital part of large-scale scientific research projects in areas such as high energy physics, astronomy space exploration and human genome projects. One such example is the Large Hadron Collider project at CERN, where four major experiment groups will generate an order of Petabyte of raw data from four big underground particle detectors each year, data acquisition starting in from 2006.Grid Technology will play an essential role in constructing world wide data a ....etc

1. Introduction
The last decade has seen a substantial increase in commodity computing and network performance, mainly as a result of faster hardware and more sophisticated software. These commodity technologies have been used to develop low-cost high-performance computing systems, popularly called clusters, to solve resource-intensive problems in a number of application domains. Particularly, in the scientific arena, the availability of powerful computing resources has allowed scientists to broaden their simulations and e ....etc

Intruders
• Three classes of intruders (hackers or crackers):
– Masquerader
– Misfeasor
– Clandestine user
Intrusion Techniques
• System maintain a file that associates a password with each authorized user.
• Password file can be protected with:
– One-way encryption
– Access Control
• Techniques for guessing passwords:
– Try default passwords.
– Try all short words, 1 to 3 characters long.
– Try all the words in an electronic dictionary(60,000).
– Collect information ....etc

GEMINI (Generic Monitoring Infrastructure) is a lightweight
framework for providing monitoring data of various types over
Web Services in distributed environments. GEMINI can collect
data about different types of entities including applications,
resources or services. Generic sensor infrastructure is provided
to enable users to create and deploy their own sensors and produce
data into GEMINI infrastructure. In the design of GEMINI we have
combined lightweight technologies with web services to provide
both: efficiency and interoperabilit ....etc
