Solution WPA2 Wi-Fi Protected Access 2 (WPA2) based on the IEEE 802.11i standard is an improvement to the 802.11 standard that specifying security mechanisms for wireless networks. On June 24th, 2004, this standard been uses to replaces the previous security specifications, Wired Equivalent Privacy (WEP), which was shown to have severe security weaknesses. Wi-Fi Protected Access (WPA) had previously been introduced as a solution to WEP insecurities. WPA implemented only a subset of IEEE 802.11i. WPA2 makes use of a specific mode of the Advanced Encryption Standard (AES) known as the Counter Mode Cipher Block Chaining-Message Authentication Code (CBC-MAC) protocol (CCMP). CCMP provides both data confidentiality (encryption) and data integrity. The use of the Advanced Encryption Standard (AES) is a more secure alternative to the RC4 stream cipher used by WEP and WPA. 802.11 Security solution WEP WPA WPA2 Cipher RC4 RC4 AES Key Size 40 bits 128 bits encryption 64 bits authentication 128 bits IV Size 24 bits 48 bits 48 bits Data Integrity CRC-32 Michael CCM Header Integrity None Michael CCM Replay Attack None IV Sequence IV Sequence Key Management None EAP-Based EAP-Based WPA2 Authentication One of the major changes introduced with the WPA2 standard is the separation of user authentication from the enforcement of message integrity and privacy, thereby providing a more scalable and robust security architecture suitable to home networks or corporate networks with equal prowess. Authentication in the WPA2 Personal mode, which does not require an authentication server, is performed between the client and the AP generating a 256-bit PSK from a plain-text pass phrase (from 8 to 63 characters). The PSK in conjunction with th... ...sed VPN offers high network throughput, better performance and more reliability, since there is no processor overhead. However, it is also more expensive. 3. A software-based VPN provides the most flexibility in how traffic is managed. This type is suitable when VPN endpoints are not controlled by the same party, and where different firewalls and routers are used. It can be used with hardware encryption accelerators to enhance performance. 4. An SSL VPN (Secure Sockets Layer virtual private network) is a form of VPN that can be used with a standard Web browser. In contrast to the traditional Internet Protocol Security (IPsec) VPN, an SSL VPN does not require the installation of specialized client software on the end user's computer. It's used to give remote users with access to Web applications, client/server applications and internal network connections.

A human service worker’s beliefs, values and clinical gestalt play very important role in how they treat and assist clients. Human service workers strive to put their clients at ease, and to help them meet their needs. Through the text exercises and classrooms discussions I have learned that there are many things that I need to work on in order to ensure that I will be an effective and productive social worker. In the exercise â€Å"Clients I might find hard to accept† I learned that it is not for me to agree or disagree with their beliefs, but it is for me to try to see things through their eyes in order to assist them properly. The goal of every human service professional is to help those in need. To do these human service professionals must not push their beliefs or values onto their clients. I will come across clients that come from different backgrounds, environments, and who different beliefs and values. None the less they are human and should be treated as such. One must keep an open mind when working with clients. When doing so clients will feel respected, confident, and comfortable. Human service professionals must learn, and grow from past experiences. A Human service professional’s repose should be calm, exhibit reliability and confidence. Clinical repose is an area that I need to work on. I need to be able to ensure that I can remain calm, regardless of what is occurring around me, or in my personal life. Large societal and system contexts, lead to immediate contexts. It is always good to know where a problem comes from, in order to find a solution that will be beneficial. Dillon & Murphy (2003) states: The clinician's anchored and relaxed presence acts as an island of calm and allows the client to stay self-focused without being distracted by the clinician's needs or anxieties. This repose is central to supportive presence. It provides a clear but unobtrusive holding environment for the work and the relationship. Clients come to know that they can count on the clinician to remain centered and steady regardless of events and developments. Even in the face of the unexpected, clinicians try to remain as calm and reliable as possible (p. 1). My personal and professional assumptions about clinical helping and their relationships to my beliefs, values, past experiences, familiar and cultural background are: that in clinical helping one must see value for the lives, health, and well being of others. In clinical helping one can learn from past experiences, from an individual’s cultural background, and maybe by even changing one’s values after learning and forming a connection with clients. Before this course I was under the impression that my beliefs, and values have no place in the human services field, I thought that leaving them out would be best for my clients, I have learned otherwise. I have come to the realization that one’s values and beliefs are what make them an excellent human services worker. Human service professionals have a genuine concern for other people. When seeking employment in the human services field, future employees look for agencies that share their beliefs and values. I would find it very difficult to work with staff members who do not try to the best of their ability to help clients due to differences in values, beliefs, backgrounds, or preconceived ideas. The National Association of Social Workers (2009) states that an ethical principal for social workers is that: Social workers treat each person in a caring and respectful fashion, mindful of individual differences and cultural and ethnic diversity. Social workers promote clients’ socially responsible self-determination. Social workers seek to enhance clients’ capacity and opportunity to change and to address their own needs. Social workers are cognizant of their dual responsibility to clients and to the broader society. They seek to resolve conflicts between clients’ interests and the broader society’s interests in a socially responsible manner consistent with the values, ethical principles, and ethical standards of the profession (p. 1). Insights that I have gained about the strengths, I have are that my strengths in listening, and open my mind to the views of my clients are needed strengths, and will be beneficial to me and my clients. There are some areas in which I have determined that I need to work on further. I need to be more aware of the gestures that I am making, and my facial expressions, so that my clients will feel comfortable, and place their trust in me. I also need to find a way to use my values and beliefs to assist clients, but not to form my opinions, or influence decisions. Dillon & Murphy (2003) acknowledges that: Individual values are cherished beliefs that develop in the context of family and sociocultural influences. Clinicians may value anything from personal autonomy to personal hygiene and can find themselves dismayed or offended by clients who do not share their value systems. As clinicians, we need to be aware of our values and how they influence our responses to clients in ways that may leave them feeling unaccepted. Clinicians must be dedicated to being nonjudgmental—unconditionally accepting people for who they are without necessarily accepting all their behaviors. The clinician's nonjudgmental stance leaves clients free to confide openly and honestly without fear of rejection, shaming, or reprisal. As we work with clients and are exposed to diverse situations and beliefs, we often find that our values are challenged and changed. A side benefit of clinical work is that our lenses are inevitably widened so that we both see and appreciate more of the world beyond our own. We ourselves stretch and grow through exposure to differences (p. 1). Human service professionals must be able to put their feelings aside in order to serve the client. It is our ethical responsibility to not let our beliefs and values get in the way of our decision making. It is up to the social workers to ensure that their clients feel comfortable, respected, and that they have confidence in them as a change agent. I believe that I have a lot to learn, and a lot of areas that I need to work on, but with practice and awareness I will go far.

Katherine Stocked, The Help Analysis Essays

Katherine Stocked, The Help Analysis Essays Katherine Stocked, The Help Analysis Essay Katherine Stocked, The Help Analysis Essay My thoughts on this book was that I thought It could have been more interesting, but it felt very realistic. Another thought on this book was it was very dramatic in its own ways. With Miss Hilly getting everybody to turn on Skitter and Skitter having to deal with all the cold shoulders. What this book says about people in general (theme) is that everyone has there own problems and will react deferent ways to every situation. The way the white women In the book react to the help using their toilets, acting Like they have a disease. 99% of all colored diseases are carried In the urine. Compared throughout the story it seems like they start to somewhat respect the help, except the nest who helped write the book. Today we respect catheter a lot more than we did back then. Over all I would say that what this book says about people in general is that the way people react to one thing will differ from the other. The main characters In this book are Skitter, Albanian, and Mainly. The way Skitter changes Is a good change. She starts to look at the world around her and see all the problems In it. Its Like she Isnt blinded from the fake reality that everything Is fine and sees all the problems that are happening. Kind of like she had a reality check and found out that her maid had died, her best friend is a diva, that her mother is going to die from cancer, and the people she can only really turn to is the help which is basically against their laws. Abilene doesnt change at all. If anything she opens up more after writing the book with Skitter. Other than that she has not changed. Mainly has become strong enough to actually leave her husband. If she was strong before she just might be invincible now. Ninny hasnt changed much she just as even more courage than before. The author, Katherine Stocked, has been somewhat successful in creating a good piece of literature. I feel like she was trying to target the Juniors when in reality it targeted the adults. This was a slow read so it was very hard for me to keep interest In this book. Other than that she has produced an excellent book. It has very realistic scenes that may have happened In 1962-1964. For routines added to make this a good point of view type book. I feel like the author has done an outstanding Job on making this book a success.

Ethnicity and Class in Ethiopia essays

Ethnicity and Class in Ethiopia essays Cultural and ethnic diversity is extremely rich throughout all of Africa, The African continent is comprised of thousands of ethnic groups, class structures, and more than seventy mother spoken languages. The class concept is defined as a group of individuals who share a common status in society based on cultural, political, or economic position in the productive process of society (Schrader 147). Several of the ethnic groups are broken down into sub-group identities and loyalties based on kinship or age-set. Ethnicity, which is a sense of collective identity by which people perceive themselves as sharing a common historical past and a variety of social norms and customs, played a major role in the development of Ethiopia (Schrader 147). Class and Ethnicity, among a host of other elements such as education, played a major role in the impact of the relationships between males and females, the roles of elders and other age groups, as well as legitimate forms of governance and the proper means of resolving conflict. Class and ethnicity emerged as the most important factors in the social and political dynamics of the Ethiopian Revolution. A unique feature of Ethiopian society was the existence of well0defined essentially pre-capitalist social classes. Class draws on the Marxist theory and focused on economic position in the productive process of society. There was no other African country like Ethiopia, with its 2000-year-old institution of monarchy, semi-autonomous provincial nobility, and millions of downtrodden peasants. The Marxist though that all capitalist societies could be divided into a property-owning class who dominated society and exploited property, and a lower working class who were forced to accept poor jobs and unsafe working conditions. Social classes and ethnic groups were beginning to emerge with the impact of the economic changes under way and with the creation of small modern agricultural sectors and...

Obesity Essays - Obesity, Body Shape, Bariatrics, Human Weight

Obesity Essays - Obesity, Body Shape, Bariatrics, Human Weight Obesity Obesity also called CORPULENCE, or FATNESS, excessive accumulation of body fat, usually caused by the consumption of more calories than the body can use. The excess calories are then stored as fat, or adipose tissue. Overweight, if moderate, is not necessarily obesity, particularly in muscular or large-boned individuals. In general, however, a body weight 20 percent or more over the optimum tends to be associated with obesity. The body's ability to adjust food intake to body needs can be disturbed by numerous factors. Of these, hormone imbalances and glandular defects are believed to be of least importance, being demonstrable in only bout 5 percent of all obese individuals. Although obesity may be familial, suggestive of a genetic predisposition to fat accumulation, there is also evidence that early feeding patterns imposed by the obese mother upon her offspring may play a major role in a cultural, rather than genetic, transmission of obesity from one generation to the next. More generally, the distinctive way of life of a nation and the individual's behavioral and emotional reaction to it may contribute significantly to widespread obesity. Among the affluent populations, an abundant supply of readily available high-calorie foods and beverages, coupled with increasingly sedentary living habits that markedly reduce caloric needs, can easily lead to overeating. The stresses and tensions of modern liv! ing also cause some individuals to turn to foods and alcoholic drinks for "relief." Obesity may be undesirable from an aesthetic sense, especially in parts of the world where slimness is the popular preference; it is also a serious medical problem. Generally, obese persons have a shorter life expectancy; they suffer earlier, more often, and more severely from a large number of diseases than do their normal-weight counterparts. They are also more likely to die prematurely of degenerative diseases of the heart, arteries, and kidneys. More die of accidents and diabetes, and more constitute poor surgical risks than persons with normal weight. Mental health is also affected; behavioral consequences of an obese appearance, ranging from shyness and withdrawal to overly bold elf- assertion, may be rooted in neuroses and psychoses. The treatment of obesity has two main objectives: removal of the causative factors, which may be difficult if the causes are of emotional or psychological origin; and removal of surplus fat by reducing food intake. Return to normal body weight by reducing calorie intake is best done under medical supervision. Dietary fads and reducing diets that produce quick results without effort are of doubtful effectiveness in reducing body weight and keeping it down, and most are actually deleterious to health. (See dieting.) Obesity is to be distinguished from overweight caused by edema (excess retention of fluids) stemming from various diseases.

Green Logistics and Corporate Initiatives Research Paper

Green Logistics and Corporate Initiatives - Research Paper Example The concept and awareness about the green logistics have evolved over time. Earlier it was a matter of public policy agendas which was forcefully implemented by environmental pressure groups that focused on the mitigation of damages caused by the transportation system. Later on it gained more importance as the businesses realized their responsibilities towards the environment and wider society perspective stressing upon the need of sustainable development for the future. Additionally the scope of green logistics has expanded over time, it not only includes the physical distribution of finished goods but it also deals with the entire transportation system including integrated logistics which includes storing, warehousing and handling systems etc. and the supply chain management which includes interaction with upstream suppliers and downstream customers. (Ann, Button, Hensher.340) The modern researches unlike the traditional ones take into account the environmental effects of all the a ctivities of the supply chain. The traditional system while only recognized the forward distribution and logistic system, a ‘reverse’ logistic system has also been introduced over time which led to a new dimension of sustainable and green logistics. This involves movement of waste, used materials including toxic and hazardous goods for recycling and disposing purposes. This whole concept has created new markets for recyclable products and its movement. (McKinnon, Alan C.243) Reverse logistics is a modern concept in logistics which is now regarded as part of green logistics. This involves processing, planning, and utilization of resources from the point of consumption to the point of origin, unlike the traditional logistics concepts which focus on movement from point to origin to consumption only. These will usually involve activities like transportation and collection, storage, reprocessing, recycling, reusing or disposal etc. This topic has been a center of attention f or many types of research and work has been done to determine the drivers and constraints in reverse logistics and how techniques like speculation and postponement can be used to develop a better reverse green logistics. As the volume of waste is growing the government regulations for its recycling, reusing or disposing of are tightening too. (Farahani et al.206)

Current event analysis Essay Example | Topics and Well Written Essays - 250 words - 1

Current event analysis - Essay Example The article argues that the study is highly significant as the prevalence of alcoholism and depression is frequently interrelated, and no substantial treatments have yet been designed to specifically address this diagnosis. The study was conducted by Helen Pettinati Ph.D. and her associates at the University of Pennsylvania. In addition to receiving the medical treatments, the patients underwent cognitive-behavioral therapy. Over a fourteen week period, one-hundred seventy people were tested, using four treatment groups. All four treatment groups demonstrated improvements. While all four groups demonstrated improvements, the group that received the combined treatment demonstrated the highest rate of abstinence and also had the longest intervals in between drinking. The difference in intervals was extreme, with the average interval for patients with the combined drug 61 days; while the other groups combined was 15 days. While the article states that the combined treatment was most effective in reducing adverse side effects (namely hospitalization for rehabilitation), it neglects to mention if there were new side effects from the combination of the drugs. It also doesn’t neglect if research is looking into a hybrid drug that would function to treat alcoholism and depression
