A Man In The Middle Attack Computer Science Essay

A Man In The Middle Attack Computer Science Essay Today computer networks are used to transmit large amounts of data which may or may not contain sensitive information. Within this document I will be discussing ways in which your networks may become venerable to attacks. Man in the middle attacks, spanning tree attacks, security issues related to trunking, and security issues relating to identity spoofing. What is a Man in the middle attack? Man in the middle attack is a name given to a type of attack where the person intercepts communication being sent across a data network. This type of attack is also known as a Bucket-brigade attack, Fire brigade attack, Monkey-in-the-middle attack, Session hijacking, TCP hijacking, TCP session hijacking etc. Man in the middle attack is an attack that is usually performed on a internal network. Man in the middle attacks are where hackers introduce a rouge device onto the network then intercept communication between two network devices. This is done by sending out a series of ARP requests and ARP responses to two devices making them think that they are talking to each other. An example of a man in the middle attack would consist of two hosts, host one and host two. The hacker would connect a rouge device, host three, most likely on the same switch that both host one and two are connected to. Once that he is able to communicate on the network he would then send out ARP requests and responses to both host one and two making them believe that he is the other host. This will make host one and two re-route there connection through host three. once host one and host two are communicating between each other via the new connection established by host three, the hacker will now be able to capture packets sent between them. Once an attacker has performed a man in the middle attack, they can use this in a number of ways for example Public Key Exchanging, Command Injection, Malicious Code Injection, Downgrade Attacks etc. There are many tools available that network managers will use in order to monitor their networks. These tools can also be used from a hackers point of view as they allow the hacker to capture packets that are being sent across the network. This essentially allows the hacker to see what you are doing. The following tools are commonly used for capturing and analysing network traffic by an attacker WiresharkÂÂ ® is a network protocol analyzer.

The Evolution of Financial Reporting in Kuwait Essay

The Evolution of Financial Reporting in Kuwait - Essay Example In general, the Kuwaiti government decided to take a macroeconomic approach to regulation, i.e., to take an active, interventionist position and dictate rules and regulations to the private sector. This paternalistic, protective approach is known as Kafala (Sponsorship of the State). Thus, laws were passed that outlined the responsibilities of companies to provide regular financial reports and to establish the enforcement agencies in the government. Explicit authority was given to the Registrar of Companies in Kuwait to regulate accounting. The Registrar has developed the detailed administrative guidelines indicating how companies should file their annual reports. In this way, the Registrar can control the quality of domestic accounting. In addition, the government began taking steps to monitor the economy and had to have accurate financial data. At the same time, the regulations should allow enough flexibility in the choice of financial accounting to not only provide a level playing field but also encourage entrepreneurs and venture capitalists. Businesses soon learned the value of accurate financial data. In this regard, the importance of private sector associations and regulatory bodies in the establishment of standards cannot be overestimated. Eventually, as the private sector grows and matures, more and more responsibility for accounting practices will fall to the private associations as long as they remain within the framework of reporting rules proscribed by the law, by administrative pronouncement, and by practices developed by International Accounting Standards (IAS). These accounting associations are crucial in maintaining proper standards and will become even more important in the future. Financial reporting has evolved along two separate but parallel lines: Accounting Securities and the Stock Exchange. 4.2: Laws Affecting Accounting: The first law concerning accounting defines the qualifications needed to practice the profession and was passed in 1962. At first, the authority was given to the Ministry of Finance and Economy, but a few years later, it was passed to the Ministry of Commerce and Industry which now issues the licenses. Many of the articles in this law outline requirements: registrants must be of good moral character,

Tourism Demand to the Portfolio of a Developing and Developed Country Research Paper

Tourism Demand to the Portfolio of a Developing and Developed Country - Research Paper Example Tourism is defined as travel for the purpose of business, leisure or recreation. However, tourism is a very important sector for several economies because of the resultant inflows of huge amounts of money in business activities as well as creation of employment opportunities in services associated with tourism such as hospitality services, cruise ships, entertainment, airlines and transport. This paper has examined the different aspects of tourism demand and after having defined the concepts and models of tourism, a detailed analysis has been made of the demand for tourism in Switzerland and Indonesia. In arriving at the different conclusions, this paper has mainly relied on journals, magazines and books that are available on the internet. Tourism is understood as the activity related to people moving away from their normal environments for reasons that are diverse from their work or profession. Tourism is not a new phenomenon and was favored with individuals that wished to enhance t heir education while the wealthy class traveled largely for pleasure, for socializing or to personally visit destinations that were widely described in the literature or reported by travelers. With the improvement of transport systems in terms of speed and comfort, the flow of visitors increased even to far flung areas. In recent times the traveling habits of people have increased considerably primarily because of: Fast, secure and comparatively cheap modes of transport Increasing interests relative to knowing of new cultures Widespread information about the attractiveness of different places Increasing disposable incomes and leisure time in several parts of the world The earliest attempts to study tourism were made by Ogilvie (1933) who held that the word tourism was the result of the curiosity of language because till that time there was no such word in the English language. He wrote that it can be used to describe an individual that simply leaves his home or country with the obje ctive of coming back to his home after some time. His definition of tourists was, â€Å"all people who satisfy two conditions, that they are away from home for any period of less than a year and second, that while they are away they spend money in the place they visit without earning it there† (Ogilvie, 1933, p.5). In considering Ogilvie’s definition, Burkart and Medlik (1981) identified four major characteristics of tourism: They are people who undertake journeys to stay in various destinations (Burkart and Medlik, 1981, p.42). Their destinations are distinct from their normal place of residence and work so that their activities are not the same as those of the residents and working populations of their destinations (Burkart and Medlik, 1981, p.42). Their intention is to return within a few days or months, so the journey is of a temporary and short term nature (Burkart and Medlik, 1981, p.42). Their purpose for undertaking the journey is other than to take up permanen t residence or employment remunerated from within the destinations (Burkart and Medlik, 1981, p.42). A socialist approach has been adopted by Cohen (1974) in defining a tourist as, â€Å"a voluntary, temperory traveler traveling in the expectation of

Business Ethics - Essay Example The manager in charge of the project, John Fisher was accused of paying somebody to buy the frozen drinks worth 10000 dollars to help in convincing the Burger king to become a pioneer in frozen Coke promotion that would take place nationally the following year (Lovell, 2012). From this case study, several stakeholders are involved in the malpractice. There is the Burger king franchise that was the organ to help in the testing as a business partner. From their point of view, they felt cheated and moved to court to seek compensation for the loss and expenses incurred. They also were angered that a partnering company used their reputed business name in a malpractice in business. The other stakeholder was the customer that was taking the frozen coke. The customer in this scenario was neither aware of the malpractice nor harmed by the malpractice. The customer however was betrayed by the fact that the biggest beverage company could afford to generate false results to promote a new brand. Though the research was not done to evaluate the drop in the customer loyalty of Coca-Cola then, this angered the customer and made the customer question the trust of other famous products of Coca-Cola (Laufer and Coombs, 2006). The other main stakeholder was Coca-Cola itself. Given the reputation of the company, it was hard for the company to explain the malpractice as well as the firing of employees who attempted to blow the whistle on the company. From the employees’ perspective, the question of ethics in this scenario is whether to quit or to blow the whistle. For the employee, Matthew Whitley, who blew the whistle the dilemma was in either choosing his job or his integrity. In the end when he chose his integrity, he and other employees lost their job. The management of the company had a decision to either preserve their name and fire the then manager, John Fisher or retain the manager and deny the claims of malpractice. In

Air pollution - Essay Example The paper "Air pollution" discovers the problem of air pollution. If the government rewards environment-friendly businesses and actions, it will be an example of positive consequence. On the opposite, instilling habits through adverse effects would be imposing financial penalty on an industry that is exceeding the limit of emitting pollutants in the air. Where technology has given so much to life, it has also been the source of many predicaments. Technology has given human beings too many machines that they constantly engage with and consume energy. In the end, environmental policies and their proper application can significantly contribute towards a healthier greener planet. Climate change and environmental pollution are the most crucial issues in the world. One needs to study them carefully and understand their magnitude. Recently, international attention has shifted towards studying this relationship of rapid development and the resulting environmental problems. In the last few de cades, an immense development has been observed around the world but this development comes at the cost of diminishing natural resources and negative impact on the ecosystem. One of the many problems facing Saudi Arabia is air pollution. Air pollution means the introduction of different gases and solid fumes into the atmosphere. These gases and particles are composed of biological, chemical and other dangerous components. Air pollution is becoming a major concern for the citizens of Riyadh. It is one of the largest metropolitan areas.

Large firms typically use a variety of structures to manage their Essay

Large firms typically use a variety of structures to manage their organisation. Summarise and evaluate the advantages and disadv - Essay Example Good decision making in an organization is because of good communication between members of the organization a virtue that is determined by the organization’s structure. This essay tries to analyze the different types of organizational structures and gives the advantages and disadvantages of each of them. It also evaluates the different structures to come up with the most preferable structure in terms of ensuring a business’ success. The first type of organization’s structure is a vertical structure. It is a structure whereby the business leaders or managers feature at the top while the bottom features the other employers. This structure can be either centralized or decentralized. For a centralized system, the organization’s members at the center of the structure make most of the decisions while, for a decentralized structure, most of the decisions are made by the members at the ends of the chain of the organization (Mills, 2007: p 54). The main advantage of this structure is its easiness in designating duties to the lower level employees. It forms a chain structure that can be followed without difficulty. The other advantage is that it promotes efficiency in the organization. Equally important is that, it encourages the development of skills and expertise as employees find it easy to go for further learning activities. The disadvantage of this stated structure is that it requires extensive power and effort to maintain order, balance, and power. It also narrows a department’s aims and objectives not to reflect the overall company’s goals (Mills, 2007: p 58). The next type of organizational structure is horizontal structure. This one differs from the vertical structure such that there are few power levels. A single department can oversee a number of activities in the same level without necessarily going to the next level. It has the advantage of giving employers greater freedom hence good turnaround and employee satisfac tion. It can help create competition in the different organizations hence innovation and creativity. There is also easy communication and cooperation between the departments. The disadvantage of this structure is its creation of loose management; the managers have little say over their employers due to tight schedules of meeting targets and finishing work. In addition, this is attributed to managers and workers maintaining a peer-to-peer relationship at the place of work hence no respect for leaders (Mills, 2007: p 89). Following on is the functional structure. In this type of structure, employees and departments are put into groups according to the function they play. The advantage of functional structure entails the help it has in growing specialists; people of the same skills are grouped in the same department. It also helps improve skills of employees, as the poor ones will learn from the better ones since they are grouped in the same department. Grouping skills of the same natu re at one place also helps improve performance. This is mainly through combined efforts of doing a task by many employees. It also boosts employee’s morale, as an employee has to do his best since it is his area of specialization according to the grouping. The main disadvantage of functional structure involves its complicated decision-making and communication processes. Communication between the different departments to enable the completion of a task is difficult since
