(Abstract) Keywords—component; formatting; style; styling; insert (key words) Introduction There are many different kind of fault tolerance in computer architecture like failure in operating system and other hardware issues raised in our daily lives among them there is a soft error issues which is also called as semiconductor transient faults. This fault occurred by the cosmic rays or substrate alpha particle that can also have possibly corrupt the user data. A soft error event causes enough of a charge disturbance to reverse or flip the data state of a memory cell, register, latch, or flip-flop. [1] The error is called “soft” because the circuit/device itself is not permanently damaged by the radiation; if new data are written to the bit, the device will store it correctly. The soft error is also often referred to as a single event upset(SEU). If the...

...Week 9 Chapter 13 and 14 Assignment #3 Eddie L. Rhoden Instructor: Dr. Janet Durgin CIS 512 May 31, 2012 Kerberos security model: Kerberos is a security protocol invented by the Massachusetts Institute of Technology (MIT) for computer networks. Using key encryption, Kerberos allows both client and server to mutually verify each other's identity in order to safely transfer data over an otherwise unsecured connection. Since its inception, Kerberos has gained the acceptance of numerous major entities and continues to grow. When a user logs in, an authentication service verifies the user's identity and grants an encrypted ticket, which contains identification credentials (such as a randomly-created session key) and only works for a limited time of eight hours. A user decrypts the ticket with his password and the credentials are stored in the user's cache to gain access to the intended service. Once the time is up, the user will have to log in once again and request a new ticket. The ticket is destroyed when a user logs out. Compared to a firewall, which offers protection from outside attacks but limits the actions a user can perform, Kerberos allows a user to continue to safely operate over an unsecured connection by encrypting the data transfer without limiting a user's abilities. Because Kerberos requires mutual client and server verification, it prevents phishing by keeping malicious entities from posing as the server and...

...University Nanyang Avenue Singapore 2263 idicula@ntu.ac.sg 1. Introduction Organizations need to rapidly adapt to changes in dynamic markets. The design of an organization can hinder or even prevent it from responding quickly to changes in its environment. The processes along with other resources in the organization drive its workand responses to changes in its environment. Processes of an agile organization must be effective, efficient, reusable and well managed. Furthermore, they must ease quick responses to changesin the environmentof the organization. The study of designing organizational processes can stimulate us to design better organizations. It can borrow ideas, tools and techniques fromareas such as artificial intelligence, computer science, coordination science, logic and operations research. Mostof the activities performedin organizations deal with the processing of information to meet various goals. The design of an organization must support the primary activities that help the organization to achieve its goals. Information technology is providing new ways of organizing and performing activities. Transactions that required several hours of human attention can nowbe achieved in a few seconds. There are various kinds of communicationfacilities that have increased efficiency at reduced coordination costs. Information technology based tools are influencing the ways in which organizations perform their activities. Therefore, we need to design and re-engineer organizations...

...Airport Security Abstract Through the history of aviation the significance of airport security has progressively increased. Since the catastrophic terrorist attack of September 11, 2001, many changes have taken place at airports to prevent such an attack from occurring again. The purpose of this paper is to: outline airport security procedures, discuss the different technologies involved with airport security, as well as examine the components of airport security. In addition I will also discuss the Transportation Security Administration’s role in our nation’s airport security. Airport Security Airport Security is an essential of life both in America and throughout the world. Without airport security our airports would not be able to function and terrorist attacks like those of September 11th, 2001, would be more common. Passengers would be afraid to fly in fear of such a terrorist attack happening again. The airline industry would lose more revenue from lost ticket sales. Then the airports themselves would lose money from the lack of passengers boarding through their gates. Finally this lack of security would trickle down to the entire economy not only in the communities surrounding the airport and aviation industry, but to the nation’s economy as well. To keep this economic failure associated with another terrorist attack from happening, our nation must take the appropriate measures to prevent it. “Airport security procedures are designed to deter...
