Evaluative Writing Essay

This article is based on the art of attack prevention and it aims at illustrating how security attack scenarios can be used to check the effectiveness of a system in preventing a system attack. Through the use of a system known as eSAP, the authors have made a report on how scenarios of possible attacks were selected and tested giving recommendations based on their results. The article comes in handy especially at a time where the issue on information system security is quite vital for companies to maintain. This paper analyzes the article by Haralambos, Paolo and Gordon’s article as to determine its appropriateness, usefulness and validity of the study. Throughout the study, examples and comparisons will be used to evaluate the work. Further justifications will be given for all arguments put forth. Evaluation The writer starts of the paper quite well by explaining what the paper will cover in the introduction. This gives the reader an overview of what to expect because he or she already has an idea of what the article is about (Memering’, 2008). The manner in which the introduction is done is also enticing such that the reader is encouraged to read on. Further, the authors introduce the article by referring to another article from which the current one stems from. This actually encourages the reader to desire to read the previous article. For those that cannot access it however, this is a disadvantage to them. Accordingly, it would have been wise for the writers to start with a brief history of the previously completed work so that the reader does can effectively understand where they started. Failure to do this is therefore a flaw in the paper and could impact on the desire of the reader to look at the paper. The authors make use of a real life example in the article to explain how the use of scenarios can be used to analyze the information systems design. eSAP (electronic Single Assessment Process) is assessed to using possible security attacks to establish whether its three main security features which include integrity, availability and privacy can be achieved in case of an attack (Haralambos, Paolo and Gordon, 2007). Attacks such as interruption, interception and modification were used to check eSAP. The use of an example not only makes the article more interesting to read but also enhances the understandability or the reader so that he or she can grasp exactly what the writers intend to say (Memering’, 2008). Besides this, the authors make use of a diagram for illustration. According to Memering, 2007), this is an effective way of making the readers to get the idea that the author is trying to pass across at a glance. For example, when a procedure is described in steps, the reader can actually follow these steps to and understand the described process better than when only the text was available. The article by Haralambos, Paolo and Gordon is quite useful in attack prevention. In the current times, many companies have been faced with threats of system attacks hence the need to avoid them. An example is a recent attack on Kaspersky, a major anti-virus vendor which occurred on the customer support site in February 2009 (O’Donnell, 2009). Since this paper addresses the possible ways in which systems meant to handle such cases can be tested, it is of significant importance. This paper could form a useful background for information system analysts to gauge the ability of different systems to effectively address the desired security concerns. Another reason why this article is very useful is that for every factor tested, there is a recommendation given to reduce the likelihood of the occurrence of that action in real life. For example, after testing the validity of passwords and the ability of the system to keep off intruders, the authors suggest the use of one-time passwords. Such kind of advice could be used by technicians to further enhance system security and thereby protect it from attack. This study is quite relevant in the study of information system security because it is quite unique in its own way. While other studies concentrate on showing the likely situations that are may face the security system, this paper suggests ways of testing them as well. Liu and Yu (2007) are some of the authors who came closest to doing this kind of research by analyzing the possible intentions of attackers which are also contained in this paper. They however left the research at that and did not proceed to test the scenarios. According to Liu and Yu (2007), once the attackers’ intentions are identified, the countermeasures to prevent attack can then be identified. They however fail to show the criteria that would be used to prevent attacks. Through the use of the eSAP scenario, Haralambos, Paolo and Gordon bring out the concept so well and even give suggestions on how to handle attacks. It is a good way of testing the effectiveness of a system in handling various security attacks which the management can utilize to establish which system to use in attack prevention. This is in line with what Liu and Yu (2009) suggest. According to them, a system can only be useful if it performs the job it is designed for. As an example, there is no way a system can allow every employee in a department to have a password and expect that this to be a secure way of protecting their system from attackers. This is a well researched article and it would be right to say that it is valid both in terms of facts and expressions made by the authors. Before the authors could perform the test, a set of scenarios are selected which are then put through a scenario validation procedure. This is done using software inspections so that the data validity is assured. The authors also make use of numerous sources to as backup for the study which makes the information contained valid to a large extent. Conclusion A paper that succeeds in putting across the desired message is said to be appropriate. If it is of benefit, then it is useful to the leaders. Should the paper give facts that can be evidenced then we can afford to say that it is valid. The article by Haralambos, Paolo and Gordon leaves the reader with a lot of knowledge to grasp. It is well researched using various books and the results can be said to be valid as they made use of a real life situation to test the system. The authors make the article simpler to understand through the use of examples and a diagram. The recommendations given in the paper could also prove useful to future managers and system technicians in designing strategies of attack prevention.

Effective Distribution Strategy Wonderful Widgets Essay

Effective Distribution Strategy Wonderful Widgets - Essay Example It is also essential to understand the reason for approving or rejecting a certain strategy in order to determine whether a unique advantage of the cost is overlooked. The more the time spent in selecting the distribution strategy, the less the costs the company will incur after implementing the strategy. After evaluation of the above aspects, the best option for Wonderful Widgets is central management strategy. Centralized distribution strategy refers to a way of organizing the product’s recipient from the suppliers of the company and the onward delivery of the products to individual branches since the company has multiple retailing operations. After implementation of the centralized management strategy, the deliveries from the company are delivered to a central place, in huge amount, instead of delivering to a specific branch. Loads are then transported to all branches, retailers, or customers. One of the most appropriate ways for Wonderful Widgets Company to address its cur rent issues is through the creation of the central distribution center. From this distribution center, the distribution management will be able to make access to all the products of the company. In addition, the distribution department will be able to ship the products to any geographical location of its choice in a timely style. A central management strategy will allow the company management to focus on the essential aspects of the company such as retail, instead of trying to find means on how to get the products to the customers.

Shakespeare's Othello Essay Example | Topics and Well Written Essays - 1500 words

Shakespeare's Othello - Essay Example So when, convinced by Iago that Desdemona has indeed deceived him with Cassio, and after accusing Desdemona and hearing her reply of innocence, Othello is able without any doubt to attack with the sarcastic retort, "I cry you mercy then/ I took you for that cunning whore of Venice/That married with Othello" (4.2. 89-91). A long and established friend might be able to place doubt upon a new marriage, particularly in a culture where free exchange between the sexes is not allowed, and a new wife will necessarily be almost a stranger. But why such a sudden and violent response The answer there lies in several places: the culture of the time, Othello's character and Desdemona's character. When Othello begins, Iago reveals to Rodrigo his hatred of Othello. Othello had seen fit to elevate Cassio above Iago in the ranks of the military they both served. It was a position Iago thought should have been his. As Iago tells Rodrigo, Othello's own "eyes had seen the proof/At Rhodes, at Cyprus, and on other grounds" (1.1 26-27) of Iago's worthiness, and yet not elevated him to the position he deserves. Iago views Othello's decision both as a betrayal and a trap: he sees himself forever the Moor's servant, and impotent. He stays with Othello only to exact his revenge: "I follow him to serve my turn upon him" (1.1. 40). Iago's revenge is to destroy Othello, as Othello has destroyed him, not just to kill him; and perhaps to cuckold Othello, as he feels cuckolded by Othello, though via power, not sex. But where is Othello vulnerable In his position as a military leader No, Othello is the Hero-Warrior: his reputation is known far and wide; all who served with or under him hold his military prowess in the highest regard; a stranger to Venetian society due to his background, Othello has risen to a renowned, entrusted rank. Othello is the good soldier, through and through; and Desdemona-a woman of high status in Venetian society, beautiful and wealthy--is the mirror in which he sees himself. Othello, as the good soldier, followed orders and expected others to follow his. Othello came to Venetian society as a slave, kidnapped, and ended by converting, and rising within the new society, almost literally, by tooth and nail. Desdemona, on the other hand, had the opposite response to her treatment as property at least in respect to her marriage: she simply behaved as would a free woman; she loved whom she chose, and married when she chose. In this way, Desdemona rejected her casting in life as property. She had in fact shown no interest in marriage before: "So opposite to marriage that she shunned/The wealthy curled darlings of our nation" (1.2. 66-67). Does it not hint to Othello of a dangerous sense of freedom Desdemona has not acted according to convention; Desdemona has done what she will: what else is Desdemona capable of that defies convention Othello says of Iago: "This fellow's of exceeding honesty/And knows all qualities with a learned spirit/Of human dealings" (3.3, 258-259). Suddenly, Othello begins to suspect depths, complexities, dishonesties, nuances, that

Conclusion for the thesis - Essay Example However, rural areas of the world are lacking behind the modern world, in terms of growth as well as learning due to lack of exposure to the internet. This paper is seeks to examine the solutions to the rural sectors of the world with this regard. Since using a cable is far too expensive as well as complex, we will study the use of an antenna instead. An antenna is not only inexpensive, but also very easy to install and use, as well as covers a greater area as compared to the cable. An antenna can make WLAN, WMAN, WPAN as well as WWAN very easy to use. Before I start my paper, it is essential to know certain properties of antennas, to get familiar with certain terms in the rest of my paper. An antenna has four different properties. The properties are as follows: If the antenna is perpendicular to the wire, it is radiating electricity at its maximum. In case the pattern of the radiation is vertical to the whip, it could be labeled as omnidirectional. In case the whip is slightly tilted, the signal minimum, also known as the ‘null’ tends to disappear. The reason why the radiation pattern is important is because one needs to ensure that in the desired direction of communication, the null is not existent. Polarization refers to the orientation of the communication system. In case other antennas in a similar structure are oriented similarly, they are regarded as having similar polarization. In case the whip is vertical, while the antenna has a horizontal polarization, the communication pattern would not be very effective. One of the most essential concerns that would arise during this procedure would involve how well the power is transmitted to the antenna. In case the antenna’s circuit is able to carry a load of 50 ohm, the antenna needs to have an ‘impedance’ of at least 50 ohms in order to maximize its results. An antenna is essentially an electronic device that converts the

TD 5- HRM - 402 Delivering Training and Development - Essay Example This will also help the management to develop further their future training programs, including pinpointing the relevant topics or areas that are absent from the training. Level 2: Learning – Under this level, Walmart Human resource manager measures what the employees under training have learned and by how much their knowledge has increased due to the training. This level of evaluation allows the management to measure learning using the specific objectives set for the training, and this will influence their decision on whether to changes in skills, knowledge or attitude. This is beneficial to the Walmart organization as it helps them to know what the employees are learning and what they are not as this will assist them to improve future training sessions. (Clifford & Thorpe, 2007) Level 3: Behavior – On this level the management evaluates how the employees’ behavior has changed basing on training that they underwent. Behavior change translates to how much information the employees got from the training program. The Walmart management, through training, they can now provide the necessary conditions to initiate the change in their organization. (Siddons & Development, 2006) Level 4: Results – The Management analyzes the results of the training at this level. This consist of outcomes that the organization has resolute to be the best for the business, best for its employees, good for the overall Walmart

Software to Support Assessment of the Comprehensive Classroom Essay

Software to Support Assessment of the Comprehensive Classroom Technology Plan - Essay Example I am supposed to click to and fro through many pages. I am forced to look at pictures of commodities whether I want to or not, whilst attempting to find the product that I need. As a student, I am bound to figure out that the design of this website is flat. Whilst the criteria are split into sub-segments, these sub-segments are not visually identified in navigation. Therefore, in the organization platform section, there is not a single item in the look of the course-plotting links to inform the student that all administration platforms are a different sub-segment from other types of administration platforms. Additionally, varying commodities exhibited and sold on this website are supposed to be the leading items even if it means navigating through this website through the â€Å"all† criterion. Every sub-segment is supposed to have its individual color piece so that it is distinct where the student is on the website (Williams, Boone and Kingsley, 2004, p. 213). Adding a â€Å" quick search† section would enable a student to simply list all commodities or services on one page. Utilizing the uncomplicated visual technology, it is likely to have the picture for every commodity come forth when the cursor is moved above the product. Visual recognition is still existent. The stocking of the commodity is slow and makes the impression of a heavy site. Is a student looks at the home page of a commodity’s criterion; there is a huge chance that they will look at the following page. Consequently, preloading the pictures for the following pages in the background will be helpful. Such an approach will make the pictures appear on the following pages. The commodity data is surrounded by exceedingly additional visual dialogue. It is similar to attempting to hear trades tone in a noisy room. The segment that deals with the number of people who purchased a certain commodity is very busy and distracts new students (Williams,

Research Paper Example Our subject belongs to the last stage, teenager. The physical size is normal for the Asian race. His vital signs are presumed normal since he was dancing with his friends at the park. Their group is composed of dance enthusiasts. I cannot assume about his organ development. But looking at his physically, nothing seemed to be abnormal. He dances well and this shows that his vision and hearing are refined. The subject’s developmental stage showed his capability to function normally. Piaget’s Stages of Cognitive Development The Swiss biologist and psychologist Jean Piaget observed his children and in the end developed a four-stage model of how the mind processes new information met. He speculated that children improve through 4 stages and they all do in the same order. The four stages of Piaget’s cognitive development include sensorimotor stage, preoperational stage, concrete operations, and formal operations. Our subject belongs to the formal operations stage which includes ages 11 to 15. The cognition is in its final form. Our subject no longer needs concrete objects to make reasonable and logical judgments. He is already competent of hypothetical and deductive reasoning.
