...Q1. NAME AND DESCRIBE THREE AUTHENTICATION METHODS. Authentication is defined by Essentials Guide as is the process of determining whether someone or something is, in fact, who or what it is declared to be. Authentication means verifying the identity of someone (a user, device, or an entity) who wants to access data, resources, or applications. Validating that identity establishes a trust relationship for further interactions. Authentication is the first step in access control, and there are three common methods used for authentication: What you have method: – Examples of this method includes keys, badges, ID, pass cards/smart card, tokens. These are physical objects and go towards identifying you by what you physically “own”. A smart card is credit card sized card that has an embedded certificate used to identify the holder. The obvious problem here is that objects can be taken and are not tied or "signed" to any particular person. This makes it easy to loan your verification for temporary uses like valet parking, but objects can be stolen. Keys can be duplicated and IDs can be faked, What you are method: - DNA, fingerprints, voice match, cadence of your typing, your walk, talk, act. Your smell, shoeprints, aura, your retinal scan, your vein patterns. Anything that leaves the impression of YOU, but nothing that can come from someone else. These are things that can be taken from you. They cannot be faked but can be stolen. Secondary level of security, what you are is better...

...the Availability Digest Towards Zero Downtime: High Availability Blueprints August 2007 Vishal Rupani focuses on Microsoft Clustering in his very readable book, Towards Zero 1 Downtime: High Availability Blueprints. He first provides a high-level overview of many topics pertinent to high availability. He then devotes most of his book to Microsoft Clustering and to the proper installation of Microsoft’s Cluster Server and several of Microsoft’s cluster-aware applications. He follows this with a brief discussion of disaster-tolerant architectures, and concludes with a case study. High-Availability Topics Rupani begins with a definition of several high-availability concepts, such as planned and unplanned outages, single points of failure, mean time between failures and interruptions, fault tolerance, and redundancy. He then provides an overview of several important high-availability technologies. RAID RAID technology is the most common method to provide data resiliency. With RAID (Redundant Arrays of Independent Disks), data is redundantly stored on multiple disks such that, should one disk fail, the data can still be reconstructed. RAID arrays typically provide a hot-swappable capability so that a failed disk can be replaced without taking down the array. There are several configurations of RAID. Most stripe data across multiple disks to achieve improved performance. Mirrored disks, used by fault-tolerant systems and designated as RAID 1, provide an...

...agile organization that take advantage of every resource in the most efficient and effective way. One of the metrics that international truck could use would be system availability. System Availability is usually measured inversely as downtime, or the average amount of time a system is down and unavailable to end users and customers. International Truck's previous IT systems didn't share information easily. The SoA allowed information to flow much easier to and from different departments and systems, resulting in less problems and errors in areas such as manufacturing. Other key infrastructure-centric metrics that could be used by International Truck to justify an SoA are, Accuracy, scalability, and through put. These would be justified by the problem in shortfalls in inventory, excessive defects and returns, more timely information on assembly-plant problems, and the lack of easily shared information by their current system. Scalability is how well a system can adapt to increased demands. This is more of a conceptual metric that assesses your ability to upgrade the implemented infrastructure at minimal cost and service interruption. Accuracy is usually measured inversely as error rate or the number of errors per thousand or million in manufacturing. Throughput is the amount of information that can pass through a system in a given amount of...

...examples of confidentiality, integrity and availability requirements associated with the system and, in each case, indicate the degree of importance of the requirements. Confidentiality is provided by two factors: a unique access card and a PIN that functions as a password. A user must have both of these to access the system. Confidentiality is compromised by the fact that most ATM systems connect to various banks, and the source of information cannot be guaranteed to be from a proper ATM. Also, ATMs are public, and can be accessed by the entire population, allowing things like card swipe readers to be used to attack them. The importance of confidentiality is medium to high. If it is the loss of confidence in a limited number of accounts, it is medium, because it does not stop the main functions of the organization and can be corrected. It would be high if a large number of accounts were compromised. Integrity of information at the ATM is provided by the very limited interface that the machine provides to the data stored on the back end. There is no comprehensive GUI or CLI to provide a point of attack. However, the previously mentioned public access and data exchange are threats to integrity. The importance of integrity is medium to high. The alteration of a small number of accounts does not stop the main functions of the organization and can be corrected. The alteration of many could be catastrophic. Availability of the system (and the currency or information it dispenses)...

...technologies have been developed that allow multiple low cost computers to work in a coordinated fashion to process applications. The economics, performance and flexibility of compute clusters makes cluster computing an attractive alternative to centralized computing models and the attendant to cost, inflexibility, and scalability issues inherent to these models. Many enterprises are now looking at clusters of high-performance, low cost computers to provide increased application performance, high availability, and ease of scaling within the data center. Interest in and deployment of computer clusters has largely been driven by the increase in the performance of off-the-shelf commodity computers, high-speed, low-latency network switches and the maturity of the software components. Application performance continues to be of significant concern for various entities including governments, military, education, scientific and now enterprise organizations. This document provides a review of cluster computing, the various types of clusters and their associated applications. This document is a high-level informational document; it does not provide details about various cluster implementations and applications. 1.1.1 Cluster Computing Cluster computing is best characterized as the integration of a number of off-the-shelf commodity computers and resources integrated through hardware, networks, and software to behave...

...category of eBay includes 19 different platforms (e.g. skype, payPal, rent) but we'll be focusing on the search and trade platform. The other sister platforms became part of eBay due to recent acquisitions and in some cases result in architectural mismatch which would be an interesting topic for a separate case study, therefore this case study focuses on the original platform's architecture and its evolution in recent years. EBay is an eCommerce system where a user can browse to the website eBay .com and search for anything they want to buy, in auction or right away from the buyer, or to post some item for sale which other users can search for as prospective buyers. The users then arrange for payments online (using eBay's payPal system which is a separate system designed solely for that purpose and recently integrated onto the eBay platform) and receive the item by mail. Like most internet-enabled business systems, eBay is constructed using distributed object technology. It requires scalability, high performance, high availability, and security. It needs to be able to handle large volumes of requests generated by the internet community and must be able to respond to these requests in a timely fashion. In addition to the end-user application,...
