Louisiana Serial Killer Ronald Dominique

Louisiana Serial Killer Ronald Dominique Ronald J. Dominique of Houma, LA has confessed to murdering 23 men over the course of nine years and dumping their bodies in sugarcane fields, ditches and small bayous in six southeast Louisiana parishes. His reason for killing? He did not want to return to jail after raping the men. The First Victims In 1997, authorities found 19-year-old David Levron Mitchells murdered body near Hahnville. The body of 20-year-old Gary Pierre was found in St. Charles Parish six months later. In July 1998, the body of 38-year-old Larry Ranson was found in St. Charles Parish. Over the next nine years, more bodies of men ranging in age from 19 to 40 would be found dumped in sugarcane fields, desolate bayous, and ditches in remote areas. Similarities in 23 of the murders lead investigators to suspect the men were victims of a serial killer. The Task Force A task force made up of nine South Louisiana parish sheriffs offices, the Louisiana State Police and the FBI were formed in March 2005, to investigate the murders. Investigators knew the 23 victims were mostly homeless men, many who led high-risk lifestyles, which included drug use and prostitution. The victims had been asphyxiated or strangled, some raped and several were barefooted. The Arrest After receiving a tip, authorities armed with forensic evidence, arrested Ronald Dominique, 42, and charged him with the murder and rape of 19-year-old Manuel Reed and 27-year-old Oliver Lebanks. Just days before his arrest, Dominique had moved from his sisters home into the Bunkhouse shelter in Houma, LA. Residents of the home described Dominique as odd, but no one suspected he was a killer.​ Dominique Confesses to 23 Murders Soon after his arrest, Dominique confessed to murdering 23 southeast Louisiana men. His tactics in capturing, sometimes raping then murdering the men was simple. He would lure homeless men with the promise of sex in exchange for money. Sometimes he would tell the men he wanted to pay them to have sex with his wife and then show a picture of an attractive woman. Dominique was not married. Dominique then led the men to his home, asked to tie them up, then raped and eventually murdered the men to avoid arrest. In his statement to the police, Dominique said the men who refused to be tied up would leave his home unharmed. Such was the case with one unnamed man who reported the incident to the task force, a tip that eventually led to Dominiques arrest. Who Is Ronald Dominique? Ronald Dominique spent much of his youth in the small bayou community of Thibodaux, LA. Thibodaux sits between New Orleans and Baton Rouge and is the type of community where everyone knows a little about each other. He attended Thibodaux High School where he was in the glee club and sang in the chorus. Classmates who remember Dominique say he was ridiculed for being homosexual during his teen years, but at the time he never admitted he was gay. As he got older, he seemed to live in two worlds. There was the Dominique who was helpful to his neighbors in the small trailer parks where he lived. Then there was the Dominique who cross-dressed and did bad impersonations of Patti LaBelle at the local gay club. Neither world embraced  him, and among the gay community, many remember him as someone who was not particularly well liked. Through most of his adulthood, Dominique struggled financially and would end up living with his mother or other relatives. In the weeks before his arrest, he was living with his sister in a single-wide trailer. He was suffering from declining health, having been hospitalized for a severe heart condition and forced to use a cane to walk. Outwardly, there was side to Dominique who enjoyed helping people. He joined the Lions Club just months before his arrest and spent Sunday afternoons calling out Bingo numbers to senior citizens. The membership director said he was well liked by everyone he had met through the Lions Club. Maybe Dominique had finally found a place he felt accepted. What sparked Dominique to move from the comfort of his sisters home to the dismal surroundings of a shelter for the homeless is uncertain. Some suspect the family grew uncomfortable by the 24-hour police surveillance and Dominique, knowing he was soon to be caught, moved away to avoid getting his family involved in his arrest. A Criminal History Dominiques past arrests include forcible rape, disturbing the peace and telephone harassment. Feb. 10, 2002 - Arrested in Terrebonne Parish after he allegedly slapped a woman during a Mardi Gras parade. According to the reports, Dominique accused a woman of hitting a baby stroller in a parking lot. The woman apologized, but Dominique continued to verbally assault her, and then slapped her across the face. He was arrested but entered a parish offenders program instead of standing trial. Reports show he met all his conditions in the program in October 2002.May 19, 2000 - He received a summons to appear in court on disturbing the peace charges. Since it was a misdemeanor, he was able to plead guilty and pay a fine to avoid appearing in court.Aug. 25, 1996 - Dominique was arrested on forcible rape charges and booked on a $100,000 bond. According to neighbors, a partially dressed young man escaped from the window of Dominiques home in Thibodaux, screaming that he had tried to kill him. When the case was brought to court, the victim could not be found to testify. In November 1996, the judge continued the case indefinitely. May 15, 1994 - Arrested and charged with driving while intoxicated and speeding.June 12, 1985 - Arrested and charged with telephone harassment. He pleaded guilty, paid a $74 fine and court costs. Three days after Dominiques arrest for killing Mitchell and Pierre, investigators said Dominique confessed to 21 other murders, giving details only the killer would know.

Occupational Safety and Health Act Essay Example | Topics and Well Written Essays - 750 words - 123

Occupational Safety and Health Act - Essay Example The employer should provide all safety information required by the employee to assess their workplace safety based on the requirements of the OSHA. The information should be provided in a language understandable by the employee (OSHA, 2015). In addition, an employee has the right to access the results from hazard inspections in the workplace. The employee is also provided with the right to access medical records of the workplace based on injuries and illnesses. Records of medical history can also be accessed by the employee (OSHA, 2014).Self-employed persons are not covered by the Occupational Safety and Health Act (OSHA, 2015). This is based on that the Act only covers employees who may have the work rights violated. In the case of self-employed persons, the responsibility to provide safe workplace is on themselves. In addition, the Act provide for both employee and employer, the parties are absent in self-employment. Immediate family members of farm owners who only employ family me mbers to the farm are not covered by the OSHA (OSHA, 2015). The family members are partially viewed as owners since this type of farm may be viewed as a family business. Consequently, all workers in the farm are viewed more as family members than employees. The OSHA also does not provide for working hazards that are under mandate of another Federal Agency (OSHA, 2014). For instance, mine safety coast guards provide specifications for employees in their own industry. When an employee realizes violation of a safe working environment, they may file a complaint with the OSHA. The complaint may be filed through email contact to the agency or by the physical visit to the nearest office. The OSHA may contact the employer based on the complaints filed (OSHA, 2015). However, the employee may insist on the inspection of their workplace. The employee is also not required to leave their place of work after filing the complaint.

Infinite Truth Essay Example for Free

Infinite Truth Essay Since the dawn of philosophical thought there has been a desire to find truth. Now exactly what truth is depends upon whom you ask. Philosophers have been searching for truth in various forms for at least as far back as Aristotle in the first century B. C. all the way up to Carl Hempel in the 20th century A. D. To Aristotle and Plato truth was reality; To Descartes truth was found in God; To Hempel truth was found in explanation. None of these are accurate and yet all of them point toward the same truth. Reality, as defined by Plato and Aristotle, God, as proved be Descartes and ideal explanation as modeled by Hempel, all allude to the same thing. They point out that mankind is a finite being and that truth is only attainable in infinite understanding, an impossibility of man at our current stage of development. Two of the earliest known men to approach the study of reality, or metaphysics were Plato and his student/rival Aristotle. These two inquisitors of reality looked at it from opposite schools of thought. Plato sought after answers by looking at the world with an outside/in point of view. Meaning he used what he perceived in the world to draw conclusions. Aristotle on the other hand approached the world from an inside/out perspective. He applied his thoughts and beliefs to the world. Aristotles beliefs lead to him seeing only one level of reality. He felt there was only one imminent world and that forms existed within particular things. Aristotle held that form had no solitary existence and existed in matter. In order to explain that form is an inherent trait of matter he quotes Antiphon and points out that if you planted a bed and the rotting wood acquired the power of sending up a shoot, it would not be a bed that came up, but wood. (Matthews, pg. 9) To Aristotle the form of the matter was wood and form is the unchanging reality. Platos view of metaphysics shows two realms to our reality: there is the realm of changing, sense-perceptible, becoming things and a realm of forms; eternal, fixed, and perfect. The realm of form was the source of all reality and of all true knowledge. Both Plato and Aristotle use form to describe reality, which to them is truth, as being eternal in nature. So truth is eternal, or infinite in nature, but what of Platos other realm, the realm of perception. Plato, in the republic, gives an in depth explanation of how he views this sense-perceptible realm. He uses his allegory of the cave. In the allegory, Plato compares people, unlearned in his theory of forms, to prisoners chained in a cave. They are unable to turn their heads. All they can see is the wall of the cave and behind them burns a fire. Between the fire and the prisoners there is a parapet, along which puppeteers can walk. The puppeteers, who are behind the prisoners, hold up puppets that cast shadows on the wall of the cave. The prisoners are unable to see these puppets, the real objects that pass behind them. What the prisoners see and hear are shadows and echoes cast by objects that they do not see. Such prisoners would mistake appearance for reality. They would think the things they see on the wall were real. They would know nothing of the real causes of the shadows. So if the prisoners were to talk to one another about a passing object and called it a doll they would think they are talking about a doll, but they are really talking about a shadow. (Plato, Book VII) Plato portrays in his allegory of the cave a dualistic view of truth. He speaks of the eternal properties of form as Aristotle does, but he also adds his insight into mankinds finitude and inability to perceive the realm of forms completely. The fact that people take as truth what they perceive will plague philosophers into the modern era. Much later, in the 17th century A. D., in his Third Meditation Descartes proves the existence of God. He builds his entire argument upon his proof in the previous meditation that in order for him to think, he must exist. From this single observation, Descartes notices that the idea of his existence is very clear and distinct in his mind; based upon this clarity and the fact that he has just determined his own existence, he deduces a rule. All the things that he sees as very clear and very distinct are all true. He then explains that he knows that he is imperfect due to the fact that he has doubts. Clearly, knowing is more perfect than doubting. From this notion, he realizes that within him lies this idea of a perfect being and that he is incapable of producing this idea alone. Descartes also determines several qualities that God possesses merely by observing himself. Descartes thought that whatever ideas he himself had, if they contained perfections, then God would possess them. If the ideas were in any way imperfect, then God would not possess them. The attributes of God that Descartes came up with are that He is infinite, independent, supremely intelligent, supremely powerful, and which created myself and everything else (Descartes, Pg.45). Descartes then makes the point that he has the idea of infinite describing God. At the same time, Descartes is a finite being. Since it has already been established that this more perfect idea of infiniteness cannot come from the less perfect idea of finiteness, the idea could not have originated from Descartes alone. Therefore, Descartes concludes that God necessarily exists and in so doing is infinite. In his Principles on Philosophy Descartes describes how God is the primary cause of motion; and that he always maintains an equal quantity of it in the universe. (Matthews, pg. 99) To Descartes God is the infinite cause and balance in the universe. Descartes states in the beginning of his proof that all things clear and distinct are true. That is no more accurate than saying that all ideas that are ambiguous to someone are unconditionally untrue. He also states, the existence of God depends on the clarity and distinctness with which we perceive the idea of God. Therefore, if to me, it was not clear and distinct then it would not necessarily be true. But the clarity and distinctness of our thoughts depends on the existence of God. This seems to be a very circular argument and is dependent on the existence of God to prove the existence of God. Again human perception falls short of truth. Do people understand truth more in more modern settings? Over the course of the 20th century Carl Hempel came up with two models of human explanation that he organized as ideals. Bas Van Fraassen puts forth a few problems with the models. The problems he states are; asymmetry, relevance, low probability, and legality. These are not the problems with the models. The real problems come from, as Hempel puts it, the universal laws invoked?can have only been established on the basis of a finite body of evidence, which surely affords no exhaustive verification. (Balashov, pg. 51) He also says that because of this all the laws used in the deductive-nomological method of explanation are all only probabilistic. This means that the only method that Hempel actually explains is his probabilistic method. Since all laws have been shown to be probabilistic the problem falls back to the fact that they been established on the basis of a finite body of evidence and therefore causes an epistemological problem. We cant define to what degree our laws are true. We cant know the probability of these laws on an infinite scale. Hempels models should be taken as models for ideal situations, for if we had the knowledge of infinity then the laws needed would be defined and all of the infinite variables could be accounted for. So true explanation can only be attained with infinite understanding. The search for truth is as old as man himself. The world in which we live seems as true to us as anything. We see, feel, smell and touch what is around us and yet we cannot accept that that is all there is. Man instinctively has a need to organize, order and explain the universe. We have concepts like reality, God and perfection, all of which we cannot completely grasp. We are not perfect and we are not sure what it means to be real, for we know only what we can sense and yet we know our senses can fool us or be wrong. If our senses and thoughts are the only way for us to interpret the universe and they can be fooled then we cannot know what is real. We cannot fully explain anything. And yet we have a need, a desire for a force that is infinite and true. We name that force God. For in God is explanation and truth and the infinite understanding that we lack. God is what we use to explain Platos form and we are the shackled prisoners in a cave of illusion. Work Cited Balashov, Yuri and Rosenberg, Alex. Philosophy of Science: Contemporary Readings.

The Birthday Party :: Literary Analysis, Katherine Brush

When a wife surprises her husband on his birthday, an ironic turn of events occurs. Katherine Brush’s â€Å"The Birthday Party† is a short story about relationships, told from the perspective of a nearby observer. Brush uses the words and actions of the married couple to assert that a relationship based on selfishness is weak. Immediately, the narrator stereotypes the couple by saying â€Å"they looked unmistakably married† (1). The couple symbolizes a relationship. Because marriage is the deepest human relationship, Brush chose a married couple to underscore her message and strengthen the story. The husband’s words weaken their relationship. When the man rejects his wife’s gift with â€Å"punishing†¦quick, curt, and unkind† (19) words, he is being selfish. Selfishness is a matter of taking, just as love is a matter of giving. He has taken her emotional energy, and she is left â€Å"crying quietly and heartbrokenly† (21). Using unkind words, the husband drains his wife of emotional strength and damages their relationship. The husband was also selfish in his actions. With good intentions, the wife had planned a surprise for him, but he was not pleased. â€Å"Instead, he was hotly embarrassed, and indignant at his wife for embarrassing him† (13). When the narrator describes the husband at the beginning, he has a â€Å"self-satisfied face† (3). Embarrassment is a result of feeling self-conscious. Because of his self-conscious nature, he assesses first how the few people in the restaurant will view him because of his wife’s actions. He does not prioritize appreciation for his wife’s effort and care, but rather sees the worst in her misguided actions. The husband’s selfishness causes him to be prideful, which in turn causes him to destroy his relationship with his wife through his actions. In a subtle way, Brush also makes the wife’s actions selfish. Even though her husband was wrong to react in the way that he did, she was also selfish in her actions. Clearly, her husband has a shy personality because â€Å"he was hotly embarrassed† (13) in front of â€Å"such few people as there were in the restaurant† (11). Using a couple of this age (â€Å"late thirties† (1)), Brush asserts that the wife should have known her husband’s preferences and been sensitive to them. The author also uses the seemingly opposite descriptions the couple: â€Å"There was nothing conspicuous about them† (5) and the â€Å"big hat† (4) of the woman. The big hat reveals the wife’s desire to be noticed.

A Bird Came Down to the Walk

A Bird came down the  walk WRITTEN BY EMILY DICKINSON A Bird came down the walk Background †¢ Dickinson liked to write about small moments in life. †¢ She liked to write about moments between people and animals. Poem Stanza one †¢ From the first line we have the animal world entering the human world. The bird is oblivious to the presence of Dickinson. She watches on as the bird eats a worm. The use of the word ‘fellow’ is suggested to show how impolite this act is but it is only used as an element of humour. Dickinson finds this both fascinating and playful. Stanza two Dickinson continues the observation and continues to run with the gentleman theme and gives the bird an element of grace. By mentioning ‘Dew’ Dickinson shows how closely she is watching the bird as if under a microscope seeing all the minute elements perfectly. Stanza three †¢ There is a change in this stanza as the bird moves from one of grace and poise to one of caution as if it is watchful of possible threats. Even during this time of caution the bird manages to remain beautiful ‘Velvet Head’. Stanza four †¢ In this stanza the word cautious refers to both speaker and bird. While Dickinson tries to bridge the gap between man and animal the bird flying away shows that this will not happen. The bird’s flight is not shown as one of terror but rather with elegance as the bird retains its beauty. Stanza five †¢ This beauteous flight continues into stanza five. This flight is shown to be graceful and noiseless. By showing it this way Dickinson shows that the bird is graceful and is a natural part of this world disturbing nothing. She emphasises this by comparing it to more of nature’s creations. Points to note †¢ Expressing the beauty of nature †¢ Positive poem †¢ Use of imagery and punctuation key

The Whitmans essays

The Whitmans essays The Whitmans played an integral role in the settling of the West and made a lasting impression in history. The story surrounding the Whitman couple is of tragedy. They set out to do good but because of cultural differences, they did not fulfill their mission. In the course of the Whitmans lives in the Oregon Country, they encouraged and helped the westward expansion of America. They are one of the major factors of the settlement of Washington, Oregon, and Idaho. Today, there are images across the country that remind us of what the Whitmans did out in the Oregon Country. Marcus Whitman was born in 1802 in Rushville, a small town located in upstate New York. He studied under a local doctor and became interested in the medical practice. Later on, Marcus left home and went to Fairfield, New York to attend a medical school there during the early 1830s. He received his degree and practiced medicine up north in Canada (Burns and Ives). Marcus came back to New York after four years of practice in Canada and settled in the town of Wheeler. He also practiced medicine there (Morris) and became an elder of a Presbyterian church (Burns and Ives). As an elder, Marcus organized temperance, or non-drinking meetings (Morris). In the year of 1835, Marcus made a journey to the Oregon Country to look for possible mission sites (Burns and Ives). Narcissa Prentiss was also born in upstate New York in a town called Prattsburg. She was born into a devout Presbyterian family and was very committed to her religion. At the age of sixteen, Narcissa pledged her life to missionary work (Burns and Ives). She was very interested in saving the sinful and heathen souls, namely the Native Americans (Morris). After finishing her education, Narcissa taught at a primary school in Prattsburgh. She moved to Belmont, New York along with her family in 1834. At that time, Narcissa was still awaiting the opportunity to receive her pl...

Acheulean Tradition

Acheulean Tradition The Acheulean (sometimes spelled Acheulian) is a stone tool techno-complex that emerged in East Africa during the Lower Paleolithic about 1.76 million years ago (abbreviated mya), and persisted until 300,000-200,000 years ago (300-200 ka), although in some places it continued as recently as 100 ka. The humans who produced the Acheulean stone tool industry were members of the species Homo erectus and H. heidelbergensis. During this period, Homo erectus left Africa through the Levantine Corridor and traveled into Eurasia and eventually Asia and Europe, bringing the technology with them. The Acheulean was preceded by the Oldowan in Africa and parts of Eurasia, and it was followed by the Mousterian Middle Paleolithic in western Eurasia and the Middle Stone Age in Africa. The Acheulean was named after the Acheul site, a Lower Paleolithic site on the Somme River in France. Acheul was discovered in the mid-19th century. Stone Tool Technology The defining artifact for the Acheulean tradition is the Acheulean handaxe, but the toolkit also included other formal and informal tools. Those tools included flakes, flake tools and cores; elongated tools (or bifaces) such as cleavers and picks (sometimes called trihedrals for their triangular cross-sections); and spheroids or bolas, roughly rounded sedimentary limestone rocks used as a percussion tool. Other percussion devices on Acheulean sites are hammerstones and anvils. Acheulean tools demonstrate a significant technological advance over the earlier Oldowan; an advance thought to parallel a cognitive and adaptive increase in brain power. The Acheulean tradition is broadly correlated with the emergence of H. erectus, although the dating for this event is /- 200,000 years, so the association of the evolution of  H. erectus with the Acheulean toolkit is a bit of a controversy. Besides flint-knapping, the Acheulean hominin was cracking nuts, working wood, and butchering carcasses with these tools. She had the ability to purposely create large flakes (10 centimeters [4 inches] in length), and reproduce standard tool shapes. Timing of the Acheulean Pioneer paleontologist Mary Leakey established the Acheuleans position in time at Olduvai Gorge in Tanzania, where she found Acheulean tools stratified above the older Oldowan. Since those discoveries, hundreds of thousands of Acheulean handaxes have been found throughout Africa, Europe, and Asia, spanning several million square kilometers, in multiple ecological regions, and accounting for at least one hundred thousand generations of people. The Acheulean is the oldest and longest-lasting stone tool technology in the worlds history, accounting for more than half of all recorded tool-making. Scholars have identified technological improvements along the way, and although they agree that there were changes and developments during this huge chunk of time, there are no widely-accepted names for the periods of technology change, except in the Levant. Further, since the technology is so wide-spread, local and regional changes occurred differently at different times. Chronology The following is compiled from several different sources: see the bibliography below for further information. 1.76-1.6 mya: Early Acheulean. Sites: Gona (1.6 mya), Kokiselei (1.75), Konso (1.75), FLK West, Koobi Fora, West Turkana, Sterkfontein, Bouri, all in eastern or southern Africa. Tool assemblages are dominated by large picks and thick bifaces/unifaces made on large flake blanks.1.6-1.2 mya: Sterkfontein, Konso Gardula; refinement of handaxe shape begins, advanced shaping of handaxes seen at Konso, Melka Kunture Gombore II by 850 ka.1.5 mya outside Africa: Ubeidiya in the Jordan Rift Valley of Israel, bifacial tools, including picks and handaxes, which account for over 20% of the tools. Additional tools are chopping tools, choppers and flake tools but no cleavers. Raw source material varies by tool: bifacial tools on basalt, chopping tools and flake tools on flint; spheroids in limestone1.5-1.4 in Africa: Peninj, Olduvai, Gadeb Garba. Massive production of large, shaped tools, high-quality raw materials, flake blanks, cleavers1.0 mya-700 ka: known as Large Flake Acheulian in some place s: Gesher Benot Yaaqov (780-660 ka Israel); Atapuerca, Baranc de la Boella (1 mya), Porto Maior, El Sotillo (all in Spain); Ternifine (Morocco). Numerous bifacial tools, handaxes, and cleavers make up the site assemblages; large flakes (exceeding 10 cm in maximal dimension) were used to produce handaxes. Basalt was the  preferred source for cutting materials, and true flake cleavers were the most common tool. 700-250 ka: Late Acheulean: Venosa Notarchirico (700-600 ka, Italy); La Noira (France, 700,000), Caune de lArago (690-90 ka, France), Pakefield (UK 700 ka), Boxgrove (UK, 500 ka). There are hundreds of sites dated to the Late Acheulean with many thousands of handaxes, found in harsh deserts to Mediterranean landscapes, and some of the sites have hundreds or thousands of handaxes. Cleavers are almost absent and large flake production no longer used as a primary technology for handaxes, which are at the end made with early Levallois techniquesMousterian: replaced all LP industries beginning around 250,000, widely associated with Neanderthals and later with the spread of Early Modern Humans.

Leadership Failure Assignment Example | Topics and Well Written Essays - 1250 words

Leadership Failure - Assignment Example Many factors, from a leadership perspective, have been accounted for Lehman brothers’ downfall that burst out by the end of 2008. Foremost, the executive leaders of the institution seemed to be unaware of the market complexities that had changed drastically over the last few decades. Leadership can be well executed only if the leaders are proactive with respect to all aspects of the organization and changing behaviors of people, customers, market, and shareholders. Kelly and Csorba’s (2009) extensive report on leadership gaps at Lehman Brothers clearly identifies reasons for its failure. In short, this report points at factors such as leadership autonomy, inappropriate human resource practices, hierarchy versus authority, personal character and values of leaders, inappropriate decisions with respect to alignment of individual goals and objectives with that of organization’s objectives. Bill George (2008) of Lehman Brothers also pointed at the critical decisions made by leadership that focused on short-term monetary targets and incentives and lack of risk assessment. Incidences of resistance from leadership level towards risk assessment have also been reported in the Lehman’s history. This not only indicates lack of risk assessment but also lack of shared leadership concept that is extremely important to run large organizations (O’Toole, Galbrath & Lawler, 2002). Leaders need to have the courage of taking risks, however, taking uncalculated risks can be the potential threat to the organization at large. Investment in complex and highly uncertain areas were some of the most critical leadership decisions that changed the plight of the organization and all its stakeholders. Leaders need to develop careful judgment of risks and strategize appropriate risk management practices to save the organization when faced with risky situations.  Ã‚  In conclusion, leadership is a quality that an individual must possess, but not limited to fulfilling the individual’s desires, motives, or goals; it is more about taking decisions and doing actions that contribute to the development of business through all people associated with the business.

Domain Name System Problems Assignment Example | Topics and Well Written Essays - 500 words

Domain Name System Problems - Assignment Example These problems are usually associated with the system’s sparse documentation particularly in relation to maintaining and managing DNS data (National Research Council (U.S.), 2005). These problems make its master zone file to be prone to error. Therefore, this essay aims at addressing fundamental problems associated with DNS application and probable solutions to such identified problems. There are numerous but distinct DNS threat categories. Most of the problems are usually general; however, few of them are DNS protocol problems with specific peculiarities. Some of the DNS problems include packet interception, ID query and guessing prediction, name chaining, trusted server betrayal, service denial, domain names authenticated denial, and wildcards. Packet interception forms are the simplest threats on DNS including eavesdropping that translates to spoofed responses. This usually takes the real back response to the resolver. In this case, the attackers will simply tell any resolver whatever it intends the party to believe. It should be noted that the attacks from the packet interceptions are not usually unique to the DNS; however, they unencrypted the UDP packets thereby making the attacked data vulnerable to the people who can intercept such data packets; hence, transmitting or sharing them to other networks (Deturbide and Scassa, 2004). Moreover, the attacker intercepts are likely to return the desired results through reply message with other parts of the correct message; thus, generating further complications to the desired data. The solutions to the interception attacks may include assigning DNS messages through a security mechanism including IPsec or encrypting messages using IPsec. These solutions are not the best since they are expensive especially for the heavy internet or private service data users.Â
