Security On The Internet Essays (2415 words) - Cybercrime

Security On The Internet Security on the Internet How do you secure something that is changing faster than you can fix it? The Internet has had security problems since its earliest days as a pure research project. Today, after several years and orders of magnitude of growth, is still has security problems. It is being used for a purpose for which it was never intended: commerce. It is somewhat ironic that the early Internet was design as a prototype for a high-availability command and control network that could resist outages resulting from enemy actions, yet it cannot resist college undergraduates. The problem is that the attackers are on, and make up apart of, the network they are attacking. Designing a system that is capable of resisting attack from within, while still growing and evolving at a breakneck pace, is probably impossible. Deep infrastructure changes are needed, and once you have achieved a certain amount of size, the sheer inertia of the installed base may make it impossible to apply fixes. The challenges for the security industry are growing. With the electronic commerce spreading over the Internet, there are issues such as nonrepudiation to be solved. Financial institutions will have both technical concerns, such as the security of a credit card number or banking information, and legal concerns for holding individuals responsible for their actions such as their purchases or sales over the Internet. Issuance and management of encryption keys for millions of users will pose a new type of challenge. While some technologies have been developed, only an industry-wide effort and cooperation can minimize risks and ensure privacy for users, data confidentiality for the financial institutions, and nonrepudiation for electronic commerce. With the continuing growth in linking individuals and businesses over the Internet, some social issues are starting to surface. The society may take time in adapting to the new concept of transacting business over the Internet. Consumers may take time to trust the network and accept it as a substitute for transacting business in person. Another class of concerns relates to restricting access over the Internet. Preventing distribution of pornography and other objectionable material over the Internet has already been in the news. We can expect new social hurdles over time and hope the great benefits of the Internet will continue to override these hurdles through new technologies and legislations. The World Wide Web is the single largest, most ubiquitous source of information in the world, and it sprang up spontaneously. People use interactive Web pages to obtain stock quotes, receive tax information from the Internal Revenue Service, make appointments with a hairdresser, consult a pregnancy planner to determine ovulation dates, conduct election polls, register for a conference, search for old friends, and the list goes on. It is only natural that the Webs functionality, popularity, and ubiquity have made it the seemingly ideal platform for conducting electronic commerce. People can now go online to buy CDs, clothing, concert tickets, and stocks. Several companies, such Digicash, Cybercash, and First Virtual, have sprung up to provide mechanisms for conducting business on the Web. The savings in cost and the convenience of shopping via the Web are incalculable. Whereas most successful computer systems result from careful, methodical planning, followed by hard work, the Web too k on a life of its own from the very beginning. The introduction of a common protocol and a friendly graphical user interface was all that was needed to ignite the Internet explosion. The Webs virtues are extolled without end, but its rapid growth and universal adoption have not been without cost. In particular, security was added as an afterthought. New capabilities were added ad hoc to satisfy the growing demand for features without carefully considering the impact on security. As general-purpose scripts were introduced on both the client and the server sides, the dangers of accidental and malicious abuse grew. It did not take long for the Web to move from the scientific community to the commercial world. At this point, the security threats became much more serious. The incentive for malicious attackers to exploit vulnerabilities in the underlying technologies is at an all-time high. This is indeed frightening when we consider what attackers of computer systems have accomplished when their only incentive was

The Logic Behind -logic and -logical

The Logic Behind -logic and -logical The Logic Behind â€Å"-logic† and â€Å"-logical† The Logic Behind â€Å"-logic† and â€Å"-logical† By Mark Nichol Why does the English language allow one to select between, say, biologic and biological, neurologic and neurological, and technologic and technological? Why complicate our language lives with the choice? Is the universe malicious? According to one study, the suffix -ic is preferred over the variant -ical by a ratio of 8 to 1. Curiously, however, when -log precedes the suffix, the ratio is reversed. (In another example of this phenomenon, called potentiation, -ness is much more common than -ity except when the suffix is preceded by able.) But that doesn’t answer my questions. For the most part, the choice seems to be personal or institutional preference, because there’s usually no distinction no logic, for example, to selection of -logic or -logical. For example, the style guide of the American Academy of Neurology prefers the shorter form, but in other contexts, neurological prevails. One researcher points out that, as you might have guessed, -ic (from the Greek suffix -ikos) was the original suffix; -ical, formed by adding the French suffix -al, came later. For the most part, usage organically caused a divergence, so that, for example, a historic occasion is memorable, whereas a historical occasion is one that merely occurred. For another example, economic refers to economics, while economical is used more generally to refer to the quality of economy. In this case, as with some others, the former can mean the same thing as the latter but seldom does. Comic and comical, and geometric and geometrical, are two of the many other sister terms with both (occasionally) identical and (usually) distinctly different meanings. Sometimes, one form predominates for obvious reasons (fanatical, for example, developed in favor of fanatic because the original form came to be applied as a noun), but in other cases, the variation for reasons seldom clear triumphs (botanical versus botanic, for example.) So, which form should you use in a given context? The dictionary is helpful for most -ic/-ical debates, but the -logic/-logical (and -logous!) issue is an outlier. In such cases, consult an authoritative source. Want to improve your English in five minutes a day? Get a subscription and start receiving our writing tips and exercises daily! Keep learning!

Using Your Manager Skills Research Paper Example | Topics and Well Written Essays - 1000 words - 1

Using Your Manager Skills - Research Paper Example First is the definition of the words used in defining the act pollutant, point source, navigable waters, and person (Manheim, 2009). Pollutant represents the solid waste, sewage, sewage sludge, biological materials, municipal, industrial, agricultural, discarded equipment and other forms of waste dumped into the water. The point source defines pipes, vessels, or containers from which pollutants are discharged. Navigable waters are water surfaces including wetlands whether or not water vessels use them. Finally, person defines corporations, government agencies, and actual people that may dump waste in water (Manheim, 2009). Secondly, the meaning of â€Å"in compliance† with the clean water act is also fundamental in understanding the act. It means that before an individual releases waste into the water, he or she must receive approval from the National Pollutant Discharge Elimination System (Ferrey, 2010). The permit provided by the agency is dependent on the individual’s waste components in accordance with the effluent limitations. The effluent limitations are limits that determine the amount and type of pollutant that can be put in a particular mass of water (Buck, 2006). This ensures that the waste dumped in particular water masses does not have a negative impact on the people that use the water. It uses technology-based standards to determine the best existing technology that every industry can use to control water contamination. For instance, it ensures that an individual has treated the waste and reduce pollutants in the water as much as possible. Additionally, the agency determines whether a particular water surface can handle any more waste products or not. Solid Waste Disposal Act deals with solid waste disposal. Solid waste includes refuse, garbage, industrial waste, and sludge from waste treatment plants. The act aims to reduce solid waste contamination in the environment by developing cost-effective and environmentally

American religion Essay Example | Topics and Well Written Essays - 750 words

American religion - Essay Example The use of the term softening is a strategy to balance the increasing religiosity and the decline in certain religious aspects. The softening of religion in America has become an issue of debate. There are many reasons put forth to support the softening of religion. Although some scholars do not support the softening ideology, certain factors prove the idea of softening true. This paper will focus on describing what has caused the softening of religion in America. Religion diversity is one of the reasons why some authors believe that American religion is softening. In the early 1900s, there were many people who professed to be members of different religions. Specifically, there were many Americans who proved to be staunch Protestants and Catholics. In the 1970s, the number of such people had decreased immensely. Many Americans have let go of their religious affiliations and opted to become atheists. Although such people recognize the existence of God, they prefer to stay away from any specific church. Currently, there are different types of atheism exhibited by people in America. Chaves, one of the authors who have explored the softening of religion in America believes that American atheists who have distanced themselves from religious groups are more than people who are stuck to the religion. In addition, the increasing popularity of other religions such as Hinduism and Islam has contributed to increased softening of religion. The American p opulation no longer fits a homogeneous description of religion (Chaves 18). The reasons for this are because people exhibit diverse faiths and appreciate the value of religious diversity. Notably, there was a time when America registered a remarkable increase of Protestants. The increase was after different Protestant groups received much popularity. Many people joined the Protestant groups leaving behind the traditional Christianity groups. It emerges that the current trend depict a decline of Protestants. It is no

Pain in unresponsive patients Essay Example | Topics and Well Written Essays - 2500 words

Pain in unresponsive patients - Essay Example A contributing factor for this could be that the various pain scales available for noncommunicative patients generally are subjective and, therefore, lacking in inter-rater reliability. Besides, research in pain assessment tools has not been adequate. The major aims of this study are (1) to compare the Numerical Rating Scale and the Behavioral Pain Scale for measuring pain in unresponsive patients, and Pain is an important problem in critical care and accurate assessment of pain in the unresponsive patient is indeed a challenge. The unresponsive patients include pediatric, trauma, surgery, cancer, and critically ill, end-of- life cases. The attending nurses are generally accountable for pain management in the patient. It is estimated that critically ill patients dying in the ICU account for nearly 20% of the hospital deaths (Rocker & Curtis, 2003). Hence, nursing care decisions made at the end of life are crucial for the comfort of the patient. Palliative care has been defined by the World Health Organization as "the total care of patients and families whose disease is not responsive to curative treatment" (WHO, 1990, p.11). Assessment and management of pain in the palliative care is a very difficult process especially in the case of a non-verbal patient (Gambrell, 2005). Health-care providers play an active role in managing pain and providing comfort to such patients. But unmitig ated pain in the absence of adequate use of analgesics and sedatives can lead to enhanced morbidity and mortality in patients in the ICU (Ahlers et al., 2008). The tools available for pain assessment in noncommunicative patients are mostly subjective which is a great drawback. Ideally, an objective tool for quantification of pain intensity capable of providing a quick feedback would be needed to provide comfort to the unresponsive patient (Gambrell, 2005). Critically ill patients show a variety of hormonal changes and neurogenic blockade and analgesia with local anaesthetics can prevent

Slavery in Ancient Rome

Slavery in Ancient Rome A slave was a person who was usually captured in battle and send back to Rome to be sold. Most slaves in ancient Rome were acquired through warfare, and the Roman armies would bring back captives as part of a reward for their presence in battles. Some of the defeated soldiers were also brought back as slaves and normally brought in a lot of money and this could also serve as an alternative to imprisoning them or killing them. Fathers could also go on and sell their children into slavery if they had a need for money and this was actually lawful. The abandoned children on the streets could also be brought up as slaves. Slaves were brought in from all over Europe and the Mediterranean especially among the Germans, Thracians, Celts and Eastern Mediterranean. It was against the law to enslave Roman citizens or Italians living in Gallia Cisalpina. New slaves were acquired first by wholesalers who dealt directly with the Roman armies. Many of these dealers were Jewish in origin and slavery trade served as their main source of livelihood for the Roman Jews. Julius Ceasar once sold the whole populace of a conquered region in Gaul of almost 53000 people to slave traders at a go. Slaves were sold at public auctions within the empire or in shops and the most valuable were sold by private sales. The sales were overseen by Roman fiscal officials called Quaestors. Sometimes the traders built revolving stands where the slaves stood and they hung around their necks a plaque describing each slave in terms of their origin, health, intelligence, character and any other information that would help the buyer make a sale. Prices were usually pegged on age and strength and some sales have been documented to have fetched thousands of dollars in todays dollars. The dealers gave a six months guarantee if the slave showed any defects that were not stated at the time of the sale by taking back the slave or returning the buyers money. Slaves that were sold without a guarantee were made to wear a cap at the time of the auction. The experiences of slaves generally varied with the place and the person who owned them. There were many reports of abuse and harsh treatment given to slaves though it is not possible to indicate how widespread this was at the time. Cato the Elder was recorded as saying that he expelled any old and sick slaves within his household. Some defeated soldiers usually chose to commit suicide rather than be taken into slavery by the Romans. Seneca who was a Roman writer held the view that a well treated slave performed better than a mistreated slave. An example of different experience by slaves would be that of Cicero who had a slave called Tiro. Tiro was Ciceros secretary, confidant editor and right-hand man. After Ciceros death Tiro went on to publish a number of Ciceros speeches since he had known where they had kept them. Tiro also wrote the biography of Cicero, a grammar book and a book on philosophical questions and also invented a new type of shorthand that he had used to take notes from Cicero. Ciceros brother and his family were very close to Tiro and when Tiro had been taken ill before, his master; Cicero had literally taken care of him like he would have his own child. Ciceros son, Marcus, often wrote to Tiro whenever he needed any advice and the two had a relationship more of an uncle and nephew rather than that of a young lord and family slave. In 53BCE, Cicero freed Tiro. On that day Ciceros brother Quintos wrote him a letter of congratulations that read,: I am truly grateful for what you have done about Tiro, in judging his former condition to be below his deserts and preferring us to have him as a friend rather than a slave. Believe me, I jumped for joy when I read your letter and his. Thank you, and congratulations. [Tr. K. Bradley, Slavery and Society at Rome]. Scholars believe that Tiro may have turned 50 on the day he was freed. This relationship raises many questions about slavery, why did it take Cicero so many years too free Tiro if he had noted for all those years how loyal and true Tiro was? Most compelling of all, if you grew up in a world where the social institution of slavery was normal, even normative, how could one recognize the human dignity of any slave? As many enemies as slaves was common proverb heard throughout Roman lands. Most citizens believed there was a constant danger of servile insurrection, which had more than once seriously threatened the republic, and as such this justified the severest measures in self-defense. They used the law of collective responsibility: if a slave killed his master, the authorities put all of the slaves in that household to death. Slaves who misbehaved have been known to be beaten, burned with an iron or sometimes even killed, regardless of their age or sex although most slaves were usually males. Slaves normally sought freedom by escaping their homes. Historian Moses Finley noted as such, fugitive slaves are almost an obsession in the sources. Harboring of fugitive slaves in Rome was illegal and professional slave-catchers were hired to hunt down runaways. Advertisements were posted everywhere which provided descriptions of escaped slaves, and offered rewards in some cases. When caught, fugitives were brutally punished and branded on the forehead with the letter F, for fugitivus. Sometimes slaves had a metal collar riveted around the neck and such a collar was preserved in Rome and states in Latin, I have run away. Catch me. If you take me back to my master Zoninus, youll be rewarded. The legal status of slaves in ancient Rome was well defined. First and foremost slaves were property and their owners exercised dominium over slaves. Dominium was the absolute right to dispose of and control the use of a piece of property. Secondly, slaves could have no family. Any children conceived of the slaves automatically became slaves and mothers chose to kill their babies rather than expose them to slavery. Slaves formed families but they had no legal authority to protect these relationships. Third, a slave by all definition had no honor and dignity and the essence of being a slave was the inability to protect ones body. A slave was also defined by the absence of the right to a fair trial and appeal before suffering any physical punishment. Owners could beat slaves as they wished and even demand for sexual relations with slaves of either sex. The mere experience of a state in which an individual could not protect his own body from abuse was inherently and permanently degradin g. As in the case of Tiro and Cicero, Tiro was still a slave in spite of all the respect and loyalty he received from his master and his family. No-one is sure how many slaves existed in the Roman Empire. Even after Rome has passed it days of greatness, it is thought that 25% of all people in Rome were slaves. Slavery in the Roman Empire did not suddenly end, but it was slowly replaced when new economic forces introduced other forms of cheap labor.

Geologist :: essays research papers fc

Geologist The goal in mineral exploraion is to find imperious meatless. It’s what they call Ore. Ore is a mineral that have a lot of value. To find ore you want to identify target areas. Overtime narrow it down and pin point the ore of the minerals. The way geologists do this is first they would look at geological maps that show worth different rock types. Sometimes they use maps that people have already made. Geologist also uses geophysical maps to find out the different properties of rocks. Geologist use magnetic instruments to find out were magnetic rocks are. The rocks that have metal in them are magnetic. Gold and silver have different electrical signals then rocks without gold and silver.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Step two is to go in the field and try to find the rocks. Then geologist would pick different types of soil, and rock samples. Then they would take the samples to the lavatory an analyze them. If they are a high amount of gold, silver, and zinc. Geologist would call that a good area.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   If the site looked promising then the next step is they would bring in a drill. And they would drill through the rock anywhere from 100 to 500 feet. Then a geologist would look at the rock samples from drilling and have them tested at a lab.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The educational requirements for a geologist are a minimum of a bachelor’s degree in geology. The average salary for a year is anywhere from 25,00 to 70,000.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Right now there are a lot of job opportunities for geologist in South America. That’s why I would choose to live and work in South America. The geography in South America is rugged mountain terrain. Some leisure activities are skiing,snowboarding, and mountain climbing. That’s why I think South America would be a great place to live for my type of job.
