...sophisticated over time. With the increase in threat levels, stronger legislations are being increasingly issued to prevent further attacks. Most of these measures have been aimed at increasing the security of Internet information. Among these methods, the most prominent approach is security authentication and protection. This paper comprehensively evaluates the security authentication process. The paper also introduces security systems that help provide resistance against common attacks. Security Authentication Process Authentication is the process that has increasingly been utilized in verification of the entity or person. Therefore, this is the process utilized in determining whether something or someone is what it is declared to be (LaRoche, 2008). Authentication hence acts as part of numerous online applications. Before accessing an email account, the authentication process is incorporated in identification of the foreign program. Therefore, the most common authentication application is done through incorporation of passwords. Before description of the authentication process, it is important to explain some of the important terms. In this concept, the term AAA is commonly employed to mean authentication, accounting, and authorizations. Let us now...

...Abused: Postville Raid Abused: Postville Raid is a documentary made by Luis Argueta. The documentary is about the Postville Raid that took place on May 12, 2008 at a meatpacking plant in Postville, Iowa. It was known to be one the largest, most expensive and brutal immigration raid in the history of the United States. Argueta reveals the devastating effects of enforcement policies on families, children and communities. The film serves as a cautionary tale against government abuses of the rule of law, the constitution and labor rights. The day of the raid, almost 400 illegal workers employed at the Agriprocessors Inc. meatpacking plant were arrested. The arrested workers were taken from the plant to a nearby fairground, the National Cattle Congress, in Waterloo, Iowa. They were bound by handcuffs at the wrists and chained from the upper torso to their ankles in groups of ten. Hearings were being put on as fast as possible, sentencing five at a time over the course of the three days following the raid. Few workers were allowed to talk to attorneys before being presented before the judge. These immigrant workers were arrested for having false identity paper and were charged with identity theft, document fraud, use of stolen social security numbers and other offenses. Most were convicted within four days of the arrest and sentenced to serve a five month prison sentence before being deported. Many of the immigrant workers had no prior criminal record so they were offered a...

...Activity 1: 1. Lincoln attempted to carve out a moderate position on slavery, by basically saying that he did not highly like the idea of slavery however he would not stop people or states from having or acquiring slaves. He says this because he knows that if he would completely go against slavery then the South would most likely wants to split from the Union. So Lincoln attempted to keep a moderate position. 2. Lincoln contended that Douglas' ultimate goal was with regard to the expansion of slavery within the country. While Lincoln argue that equality was for all people, Douglas argued strongly against him. However no matter how much they argued both knew that abolishing slavery would be hard because it was such in demand especially in the South. Lincoln contended that Douglas' ultimate goal was with regards to extend slavery. 3. During the debate each man accused the other one about certain things. In this debate Lincoln accused Douglas of not following with Dred Scott decision. Douglas then accuse Lincoln of being wrong about his accusation. Both lies go hand in hand, during those debates each man accused the other of lying. 4. Lincoln asked whether the people of a territory could exclude slavery prior to applying for statehood. Douglas responded with the answer of yes, that prior to applying for statehood people with a territory could exclude slavery. 5. Douglas use the audience's racial fears to discredit Lincoln during the debate. The fear that the audience...

...Abstract Redundant Array of Independent Disks, universally known as RAID is a subsystem for disks by definition and as first coined in the year 1987 by David, Garth and Randy Katz at the University of California. Initially RAID was created to combine a number of cheaper drives in order to provide high capacity. However today RAID is designed for providing one of the most important, essential and looked-for feature in any system i.e. “fault tolerance” or “failover protection”. Fault tolerance increases the overall efficiency and reliability of the system. This short paper provides a pragmatic overview of RAID in general, the two methods used in RAID to enhance its reliability and performance, pros and cons associated with RAID and a contrast of RAID level 1 and RAID level 5 schemas on the basis of read and write actions. Introduction RAID has a different drive just for replacing the drive that has crashed. This spare drive is called hot spare. This drive can be compared to a spare part that is used during emergency. This spare drive must always be ready and the replacement of the failed part (drive) should be done straightaway. After replacing the failed drive with the hot spare drive it is required that the entire system knows that the spare drive is being used. In addition we should also take a backup of all the data, just in case the spare drive also fails. However, RAID rules the technology used in implantation of secure systems. Physical and logical arrays and disks...

...Sweatshops in America Having a globalized economy provides easy access to just about anything we want or need; however we almost never know where these items come from or how they were produced. You don’t need to go to a third world nation to find a sweatshop as they are very prevalent in California and New York. Sweatshops exist because large retailers don’t produce their own clothing. They hire manufactures to coordinate production, and the manufactures typically enter into contracts that require quick turnaround. Sweatshops in America produce a big portion of the shirts, dresses, blouses, and skirts on the shelves of big American retailers. Retailers often claim they are unaware of the conditions in which their clothes are produced. The retailer reaps the benefits of this labor; without, taking responsibility of the cheap production. Sweatshops are back in America because in recent decades, many garment manufacturers have moved overseas and unions have become less powerful. Devastating budget cuts severely limited the U.S. Department of Labor policing of garment factories. There are now only 800 wage, and hour inspectors employed by the Department of Labor. They inspect six million work sites of all kinds in the USA making it easy to avoid inspection. It is estimated that 4,500 of New York’s 7,000 garment factories are sweatshops. These sweatshops are often mobile operations, making them even more difficult to regulate. The only equipment that is really needed...

...Devin Capuani History 103 Book Report September 28, 2014 Raising Holy Hell The novel Raising Holy Hell at length discusses the madness of John Brown and his life leading up to his famous raid on Harper’s Ferry. John Brown was a radical abolitionist from Connecticut who believed in the violent overthrow of slavery as opposed to law .The raid was just the beginning to rising tensions between the North and South upon the issue of slavery. The raid on Harper’s Ferry lasted only three days until Robert E. Lee had a garrison of marines storm the engine room at Harper’s Ferry and capture all of the raiders. John Brown was captured as a result, put to trial where he was found guilty and executed by hanging. On page 31, there is a piece from John Brown Jr., which talks about the death of his mother. In the passage, the boy talks about how the death of his mother was explained to him and his siblings in religious terms. His father told them that their mother was now with God in heaven but the boy chose not to believe such things. The part of the passage that is the most interesting is the last bit, the boy was fearful of incurring his father’s wrath so never told him the truth. This signifies that John Brown was a very violent man, not only to slave supporters but for his own children to fear speaking their minds due to their father’s anger is a big clue into his personality and in the case of this book, his insanity. The next section that stands out is on page 37. The section...

Science College, Raipur (C.G.) sharmaanil.mail@gmail.com Abstract— Cloud computing is a new field in Internet computing that provides novel perspectives in internetworking technologies and raises issues in the architecture, design, and implementation of existing networks and data centers. In these beliefs, users of cloud storage services no longer physically maintain direct control over their data, which makes data security one of the major concerns of using cloud. This paper investigated the problem of data security in cloud data storage, which is fundamentally a dispersed storage system. Index Terms—Cloud Computing, Data Storage, Security, Green Computing. 1. INTRODUCTION The remarkable development of cloud computing in recent years is increasingly sparking the interest of Internet and IT users seeking to derive the greatest benefit from the services and applications available on line via the web in service-on-demand mode with per-usage billing. Cloud computing offers a new economic model for ICTs – a model which heralds new modes of investment in, and operation of, IT resources. With cloud computing, organizations, institutions and companies no longer need to invest heavily in such resources, which are of necessity limited and require burdensome and costly internal...

...Term Paper Data Warehousing and Data Mining Term Paper Data Warehousing and Data Mining A Data Warehouse Saves Time, Enhances Data Quality and Consistency, Provides Historical Intelligence, Generates a High return on investment. One of the benefits to using a data warehouse is that it conveys Business Intelligence By providing data from various sources. Management executives no longer need to make decisions based on finite data. Time is saved by allowing business users to get data quickly from one location so they can make quick knowledgeable decisions and will not waste time trying to get data from several places. Using a data warehouse implementation provides for better data quality and consistency by converting data from different sources into an individual common format. Since data from each department is standardized, each department will have results that are in alignment with the results of all other departments. Doing so assures the accuracy of data and that provides for better business decisions. Since a data warehouse holds large volumes of historical data, it can analyze trends over a time frame so that predictions can be made. This type of data usually cannot be kept or used to get reports in a transactional database. Finally the return on investment for companies instituting a data warehouse and a Business Intelligence system generate more money while also saving money. The purpose of data mining is to provide knowledge to give company an advantage...
