AN INTRODUCTION TO INFORMATION AND CYBER SECURITY Thesis
AN INTRODUCTION TO INFORMATION AND CYBER SECURITY - Thesis Example Nessus, on the other hand, is used in more than 75,000 organizations around the globe and it is considered to be one of the worldââ¬â¢s most popular vulnerability scanner (Ferguson, n.d.). However, the third version, i.e. version 3, has now been converted to a proprietary license as the scanning engine is still free and updates are also available after a week on a release. When Nessus is incorporated in a large enterprise, most probably, a government organization such as Department of Defense (DOD) networks, it will initiate a port scan and target the defined host or a network. After opening the port, it examines all the services that are running on the system or network and tests all the detected services against vulnerabilities defined in the Nessus vulnerability database (Kim, n.d.). As this tool can develop a testing platform for network resilience, the report generation is very comprehensive that is ideal for large enterprises. As it is an easy remote based vulnerability analysis tool, it can be best suited for large enterprises that are geographically dispersed in more than one continent (Kim, n.d.). Moreover, in an ideal scenario where corporate networks for large organizations contain many client/server architectures, Nessus will detect the clients and the server automatically when connected to the specific network at a specific location (Kim, n.d.). Network security professionals of a large enterprise can customize plugins, as per their requirements, as the tool has its own scripting language for defining methods to test and identify network for vulnerabilities (Kim, n.d.). The tool will penetrate within the corporate network and start scanning anonymous File Transfer Protocol (FTP) and for the client/server architecture, secure socket Layer (SSL) will provide an additional layer of security for report results. However, for false positive detection, a validity check is required on the reports from

Infant mortality Essay Example for Free
Infant mortality Essay Infant mortality simply refers to the number of death amongst the young ones per 1000 births. In this historical study, infant mortality rate between a range of time starting from 1750 to 1917 is studied. Its rate varies from one century to another with the 18th century recording the highest number of deaths among the young. Progressing towards the 20th century, there has been a drastic decline in the death rate of infants. Some medical professionals believe that this is because of the social health reform and medical improvement during the 19th and 20 centuries. On the other hand, some scholars, like Thomas McKeown, strongly suggest that this is mainly attributed to the improved nutrition and sanitation of the infantââ¬â¢s environment (McKeown, 121). Thomas McKeown is the scholar who spearheaded the well known McKeown Thesis. There has been an ongoing debate between the two ideas about which played the main significant role in checking the rampant death of the infants for several decades featured in countless student reading, so who actually saw the truth between the 19 and the 20th centuries? Infant mortality reduced over the centuries starting in the late 19th and early 20th century in the United States. The highest rate of death among the infants was observed in the first half of the 18th century (McKeown, 65) , this high rate of infant mortality was viewed as caused by societal break-down and poor policies rather that specific pathological organism. This was considered as a reflection of a poor frame work in the society. Between 1750 and 1800, the infant mortality rate was at the peak with many of the infants succumbing to their diseases. At the time, the technical aspects in undertaking comprehensive investigation to establish the actual cause of the diseases and finally finding the cure had not been successful. Many infants therefore died in large numbers. The community attributed all this to the broad and unfortunate societal problems. Many major countries had areas with indecent housing, flooded basements, contaminated water supplies and poverty, resulting in diseases such as typhoid, scarlet fever, tuberculosis and typhus to thrive (McVeigh). This in the end challenged them to actually think of ways to handle these problems. What they have come to conclude was that prenatal and postnatal diseases were ultimately influenced by external factors such as food deficiency, alcohol and tobacco use (Mudd, 117). While diseases and disabilities that are determined during conception or after birth are invariably different, both their origins can still be potentially controlled. In the second half of the 19th century and the first decade of the 20th century, the government of the United States came up with efforts to curb this menace. They recommended the removal of infants in the cities; this was considered a major success since most mothers who were residing in the city end up having their young ones dying at a tender age. Some prenatal diseases, for example was due to exposure to harmful toxins in the environment, thereby affecting the childââ¬â¢s development in the motherââ¬â¢s womb (Mudd, 117-118). This was viewed that the city exposed the young to unhealthy environment hence exposing them to diseases. The congestion in the city was also found to facilitate the spread of contagious diseases among the young. Various forms of pollutants were rampant in the city and therefore the infant could easily contract infections. Many women at the turn of the 18th century were working in gas lit factories and sweatshops, which may affect their pregnancy (McVeigh). The mothers were advised to settle in their rural homes where these hazards were considered to have minimal consequences on the infants. It was fortunate that legislations were finally passed during 1848 to promote genuine concern for public health (McKeown, 66). Similarly, international city in Great Britain during the era, as well as an important location throughout Europe and the rest of the world in terms of international trade and human transit. Because of so many international produce, goods and people arriving in London daily, it became clear to medical professionals that foreign bodies can often be the bearers of disease; from London, such illnesses were doomed to spread throughout the rest of the country. In helping Londonââ¬â¢s citizens stay healthy, infant mortality rates were automatically dropped simultaneously. By exploring Londonââ¬â¢s newspaper archives, as well as other contemporary newspaper articles and even the correspondence of health care workers during the era, the information concerning infant mortality rates can be gathered and compared. In contrast, some scholars, such as Thomas McKeown, strongly suggest that this is mainly attributed to the improved nutrition and sanitation (Colgrove). The milk supply was improved among the young one, because the milk handling and supply of edible products was improved by the government. This government strategy has been significant in preserving the life of infants at the time. Child hygiene was another factor considered in checking the high rate of infant mortality. A child hygiene program was established by the government to ensure the infants were provided with the highest quality of hygiene . With the advancement on the technological innovations, infant mortality reduced in significant proportions over the centuries. The discovery of the various medical equipments and apparatus including the microscope and the stethoscope in the late 19th century boosted the medical fieldââ¬â¢s capabilities to handle these challenges (McVeigh). Simultaneous to this, great strides in the improvement of education of interns started happening in Europe. The scientist who specialized in medical microbiology studied deeper and discovered very many minute microbes which were found to cause high rate of infant mortality. These microbes were found to thrive on unhygienic conditions therefore causing high rate of infant mortality. They were found to be rampant especially in poorly handled milk and other foodstuff. With these discoveries of stethoscope and the microscope in the 20th century, many diseases were kept under control. This was because scientists had become knowledgeable about health matters. Before this tremendous discovery, many minute microorganisms causing several diseases amongst the young ones were at large and scientists were puzzled with unchecked high rate of infant mortality. The electron microscope with high magnification enabled these scientists to recognize the various disease causing organisms including viruses and bacteria. They managed to know the specific diseases that these microorganisms caused and the appropriate control measures needed to keep them at bay. They came up with antibiotics to cure infection in the infants. Antibiotics such as penicillin were also discovered in the early 20th century. At this time, due to these discoveries and appropriate measures taken by the government, the infant mortality drastically reduced. Medical attention to the infants was considered a priority and hence reducing the rate of infantââ¬â¢s death. Another important factor in curbing infant mortality is the development of obstetrics and the rise of gynecology in that time (McVeigh). It encompassed all aspects of pregnancy, and allowed sanitary and safe conditions for the mother and child. Arguably, poor sanitary conditions during childbirth are also one of the main causes of infant mortality in earlier centuries. McKeownââ¬â¢s views on public health sparked controversy during the 1970ââ¬â¢s and 1980ââ¬â¢s with its focus on allocation of medical resources. While the foundation of his empirical views might be considered flawed today, it spearheaded studies of where should public health practitioners should focus their efforts and the most important determinants of a societyââ¬â¢s mortality (Colgrove). The thesis he authored was about the explanation of the dramatic population growth from around 1770 to the present (Szreter). It stated that it was because of the domino effect of improved economic conditions: better standards of living and enhanced nutritional status that strengthened infant resistance to most diseases. His works have been about the synthesis of these advanced ideas and later on his works began getting much attention because of its profound content (Szreter). It was curious to note that it attracted more audiences during its later years, even though it didnââ¬â¢t substantially contain any new information. It was probably the stronger awareness in public health that caused this. However, McKeown will always be considered a figure of importance because of his role in shaping contemporary systems to prevent infant mortality. Other factors that can be attributed to a precipitous decline in infant mortality rate starting from the late 19th and early 20th century include the improvement in economic growth, improvement in nutrition, new sanitary measures by the government and advances in knowledge about infant care in the united states of America (Colgrove). Though little is known about how each of this factors contributed in the reduction in the infant mortality rate, a systematic review of the data from the specific period stressed that providing clean milk in market was the main contributor to this decline in the infant mortality . However, the writer of this journal was biased in the sense that handling milk supply and milk hygiene was not the only cause of infant mortality. Itââ¬Ës important to note that the both technological advancement and improved nutrition played a very crucial role in checking the infant mortality rate starting from the late 18th to early 20th century. The perception that the high rate of infant mortality was due to societal problems and poor policies could not help in reversing the trend in the first half of the 18th century. Technological advancement saw the discovery of the various medical apparatus and equipments in the 20th century which helped in the reduction of high infant mortality rate. The scientists discovered the actual causes of these deaths being pathological organism which could be controlled. The economic growth and education enabled this scientist to conduct further research and hence control measures were devised which came up with cure for various diseases affecting the infants.

Automation Technologies in IT Organisations
Automation Technologies in IT Organisations Most IT organizations would have several automation technologies in use. Scripting would be the most popular method of automation in IT. Automation is the connecting of different systems and software in a way that they become self-operating. Examples of these systems used are: Artificial Neural Network Distributed Control System Programmable Logic Controllers Supervisory Control and Data Acquisition Intelligent Automation In many organizations, automation could be used for data centre operations and batch processing of large files. This would do away with the need for IT employees during this period, with the I.T professionals only being required if a processing situation accoutred. This use of mechanical and electronic equipment will decrease the need for human interaction Distributed Control systems control action is distributed and monitoring is centralised. The whole system of controllers is linked by networks for communication and monitoring. It a designed control system used to control complex, large, and geographically distributed applications in industrial processes. It divide a large application into multiple smaller subsystems, each of which carries out a portion of the application, and allow these subsystems to communicate with one another. Distributed control systems have advanced from two older technologies, direct digital control, and hybrid control. (Siemens, 2007) Distributed controllers are linked to field devices and operating PCs through high speed communication networks. Discrete field devices such as sensors and actuators are directly connected to input and output controller modules through communication bus. These field devices or smart instruments can communicate with PLCs or other controllers while interacting with real world parameters like temperature, pressure, etc. (robo, 2016) Discrete Control Systems features Can process complex processes System redundancy Scalable platform System security (robo, 2016) says An important concept in a DCS is the of breaking down of software into smaller logical parts, independent of system hardware. This makes system design much more effective as the software is smaller. This makes it easier to write, debug and maintain than the larger programs in computer and PLC systems An automated system doesnt learn from previous experiences, a simple example of this would be an email spam filter. Occasionally, vital emails wind up in the spam folder while spam emails gets past the filter (Rouse, 2012). Intelligent automation is helps to solve this errors. The benefits would not just be cost reduction but can lead to Accountability Efficiency Predictability Greater scale Product innovations Intelligent automation is changing the way business is done and has progressed substantially in recent years. These new developments is to have a massive impact in the world of work. IBM has announced a $1 billion investment to commercialize its Watson cognitive computing technology. (Deloitte, 2015) Systems and software can detect and produce enormous amounts of data that then automates the entire processes, adapts, and improves.Ã Application variety from the essentials to the ground-breaking. These can be anything from data analysis to unmanned self-driving cars.Ã Intelligent automation software needs to understand your business developments and their variations. It has to take into account that data when performing automated business developments authentication to verify that the correct business result happens. The variety of business difficulties in which these services and software can be used on the increase as new technologies for voice recognition, natural language processing, and machine learning advance. They can be used by most people and are gradually becoming accessible as open source or low-cost products. Employee resistance (worker displacement) Less versatility by having a machine that can perform a certain task limits to the flexibility and variety of tasks that an employee could do. High Cost of upgraded machines can be expensive, operating costs and maintenance for this equipment will add extra cost. Machines can be anywhere between thousands and millions of euro depending on the automation. Increase in unemployment more advanced automation will leave more people out of work. Unpredictable costs there can be several unpredictable costs that may exceed the actual cost saved by the automation itself. Some of these costs could include research and development costs of automating a process, preventative maintenance costs, and the cost of training employees to operate automated machines. The technologies are starting to become available and if applied correctly and it can lead to opportunities for the future. The opportunity could be beneficial for workers, doing away with repetitive and dangerous work in all forms. This could lead for people having a higher standard of living and a better way of life. Business benefits would not only be cost reduction over time but can better use the highly skilled workers in other project critical areas. It would lead to faster and better results, better services and products. Deloitte. (2015, 03). deloitte.com.

Documentary on Newfoundland :: essays research papers
Canada is internationally recognized for its excellence in documentary film, and in recent years several of Canada's finest documentary makers have come from this province. Some of them work primarily in Newfoundland and Labrador while others take their cameras around the world. Their films often tell highly personal stories that reflect universal themes, and many are characterized by an unmistakable passion for grass-roots politics, social change and human rights. For most of this century Newfoundland and Labrador stories and events were interpreted through the eyes of visiting filmmakers. Producers from Great Britain and the United States arrived as early as 1907 to do brief pieces about hunting, fishing and wildlife. The National Film Board of Canada (N.F.B.) made several short films here in the 1940s and came regularly after Confederation, eventually building a library of over 100 films about the province. Local directors and producers did not contribute to that library until the 1980s. A few Newfoundlanders were shooting footage in these early years, but usually out of personal interest and with no intention of creating narrative films. Finished projects by local cameramen and editors began to appear after the second World War. They included The Golden Jubilee of Archbishop Roach (1947) by W.J. Ryan and The Land We Love (1955), a travelogue of the Avalon Peninsula by Len Earle. By the late 1960s the CBC and CJON television stations were filming news, entertainment and information programs. Memorial University's Extension Service established a "media unit" to make educational films and documentaries and record significant public events. The unit also worked with the NFB on several projects, including a series of short films on Fogo Island that incorporated input and feedback from local residents. CJON at Buckmaster's Circle, 1952.

Fourteen of them formed the Newfoundland Independent Filmmaker's Cooperative (NIFCO) in 1975. although dedicated to the making of dramatic and artistic films, NIFCO has also been vital to the development of a home-grown documentary industry. The early NIFCO documentaries focus on the province's history and heritage and are only a few minutes long. Stone's Cove (1980) profiles a resettled community through contemporary footage and old photographs. Dig At Cow Head (1982) is a brief portrait of an archaeological dig.

ETs And UFOs :: essays research papers
ET’s & UFO’s à à à à à Nearly 600 years before Christ was born, the biblical prophet Ezekiel saw something unusual, very unusual, that he tried to explain; “And I looked and behold a whirlwind came out of the north, a great cloud, and a fire enfolding itself. Also out of the midst thereof came the likeness of four living creatures.'; Since then, several similar Unidentified Flying Objects (UFO’s) are reported around the world. The Romans, the Greeks, moreover the great emperor Charlemagne saw it… saw what? For Christians, there is no doubt about it; Ezekiel described angels coming down on Earth bringing messages from God. However, this is not the only possible explanation. Where scientists see a complex natural phenomenon, others will see a “wheel in the middle of a wheel'; simply as an extra-terrestrial vehicle observing our planet Earth. à à à à à The movie ‘UFO’s, It Has Begun’ seems to be persuading enough to prove that extra-terrestrials do visit Earth. Burnt grass, cattle mutilations, capturing aliens, photographs, strange powder; all this evidence is presented in the movie. Unfortunately, most of it is incomplete, and there is nothing that could explain the sightings, besides, incredible film techniques and mysterious music highlights the obvious bias of the movie. On the other hand, 96 per cent of all the sightings can be explained by today’s science, that are identified as Venus, the Moon, reflections of light, electric charges, and weather balloons. The remaining 4 per cent maybe flying saucers which scientists deny the idea. Truly, if we think about the unimaginable time and energy needed for such an interstellar journey, it seems that visits of ET life forms to earth are quite unlikely. à à à à à Stanley Miller showed in 1953 that organic molecules can be made if ammonia, water vapour and hydrogen were irradiated. Therefore, scientists do have a strong belief that ET’s exist. An American astronomer, Frank Drake, tried to detail the probability of life elsewhere in the galaxy, and according to him, 10 per cent of nearly 400 billion stars in our galaxy are similarly like our sun. Therefore about 40 billion are possibly life-giving stars, and of these, maybe only 4 billion are like our Earth. The remaining 90 per cent are either too hot or too cold. Of course life and intelligence are not the same, and that means that our Earth is surrounded by at least 400 galactic neighbours. à à à à à Later on, humans decided to launch signals into space with modern technology, in hope to make contact with aliens.

Euthanasia Needs to be a Legal Option Essay -- Argumentative Persuasiv
Euthanasia Needs to be a Legal Option à "Warren Hauser is dying. Should the Supreme Court decide that terminally ill Americans have a constitutional right to commit suicide with a doctor's help, he would qualify. Emphysema and valvular heart disease have left him debilitated and physically dependent" (Byock). For terminally ill patients like Warren, where death is inevitable and would be less painful than living, euthanasia should be a legal option. Euthanasia is Greek for "easy or happy death" and implies measures deliberately taken by a physician to curtail pain and suffering. This concept has been enlarged to include such action in incurable diseases, especially those in which the patient must endure torment and extreme pain and/or is terminally ill ("Euthanasia"). Euthanasia is the intentional killing by act or omission of a dependent human being for their alleged benefit. If the death is not intended, it is not an act of euthanasia, so the key word is "intentional." Assisted suicide is when a person provides an individual with the information, guidance, and means to take their own life. When a doctor helps them take their life, it is labeled physician-assisted suicide. However, there is no euthanasia if what was or sometimes was not done does not intentionally cause the death. In some cases, medical actions are labeled "passive euthanasia" since the intention of taking life is lacking. Active euthanasia is intentionally cau sing a person's death by performing an action such as giving lethal injection ("Euthanasia Definitions"). Passive euthanasia can be more painful because neglecting care for a terminal patient puts them through more suffering and pain than active euthanasia, which speeds up death and avoids pain and s... ...bout/newsday.htm> à Hendin, M.D. Herbert.

Charge of the Light Brigade and the Last of the Light Brigade Essay
The themes of The Charge of the Light Brigade and The Last of the Light Brigade both have to deal with soldiers battling for their country; however, the key difference that separates the two is that the theme of The Charge of the Light Brigade has more of a positive tone than The Last of the Light Brigade The themes of both The Charge of the Light Brigade and The Last of the Light Brigade bot have to deal with soldiers battling for their country; however, the tone of the two different poems is different that differentiate the two. In The Charge of the Light Brigade, the tone of the poem has more of a positive aspect: ââ¬Å"Boldy they rode and well,/Into the jaws of Death,/Into the mouth of Hell/Rode the six hundred,â⬠(Paragraph 3, line 6-8). This shows how they boldly rode into battle, which is a more of a positive connotation because they are doing an act of bravery for their country. In this instance, the people in The Charge of the Light Brigade were portrayed in a more positive aspect than the latter. Another key contrast between these two poems is that the connotation and the diction they used is quite different. In The Last of the Light Brigade, they use diction that conveys the tone of melancholy and depression, whereas The Charge of the Light Brigade has a more positive aspect. ââ¬Å"They had neither food nor money, they had neither service nor trade;/They were only shiftless soldiers, the Last of the Light Brigade,â⬠(Lines 3-4). This gives the poem a more desolate tone by saying they did not have money or food, and that is the words that the author uses to convey the message in the poem, whereas The Charge of the Light Brigade use more positive diction that gives the reader a sense of optimism. ââ¬Å"Stormââ¬â¢d at with and shot and shell,/ boldly they rode and well,â⬠(21-22). In this aspect, it shows that the soldiers were given a more positive aspect just by the words they used compared to the Last of the Light Brigade, which is a more desolate poem due to the words they chose. Overall, the poem is very similar in many aspects, but the differences keep these poems extremely distinct from each other. They all have to do with battle, but the diction and themes in both poems causes them to be different from each other.
