Cyber Defense Program in Military Schools Essay Example
Cyber Defense Program in Military Schools Essay Cyberspace has developed into a difficult abstraction presenting innumerable fresh potential and services as well as possibilities for enemies to cause destruction. Lately, the United States Armed Forces has affixed ââ¬Å"Cyberspaceâ⬠to its mission statement because it distinguished the substantial effect of this new field of expertise. Education act as a fundamental role in producing cyber soldiers to maintain the mission of the United States Military. (Dodge Ragsdale, 2005) The NSA funded the cyber defense exercises presenting priceless real-world knowledge about the new field of cyberspace. The Cyber Defense curriculum was started in the Military schools in 1999. Another reason for the implementation of the Cyber Defense Curriculum for the military schools is the increasingly plausible fact of the growing number of hackers that threatens national defense. The Y2K predicament was a significant problem that was faced in the start of the millennium. (Dodge Ragsdale, 2005) Students started to receive training on how to create and defend cyber weaponry. The course was called Information Assurance. The objective of the course was to enhance consciousness of security issues with information systems. (Felder Brent, 2003) In the Information Assurance course, learn many offensive and defensive techniques in the cyber domain. Cadets can write malevolent applets and viruses but at the same time, form defense mechanisms from it. The reason of this course is not to craft them to become hackers but give them the knowledge of how potential enemies might exercise cyber warfare and target their vulnerability especially in the commercially prevailing information systems.

The partakers chosen were the West Point Academy, the US Air Force Academy and the Naval Postgraduate School. The schools were divided into teams were engaged into a cyber warfare. The team that scored the most number of points in the offensive and defensive ordeal is declared the winner. In the successive years, more military school joined the competition. (Cyber Defense Exercise, 2009) Evaluations of the Cyber Defense Program There were several evaluations that were made for the Cyber Defense Course and its relative fields. The studies focused on both technical and general aspect of the program. Although it was effective in developing the skills of the cadets, some other issues were still in question. The following were some of the research questions of the evaluations: Is the Cyber Defense Program cost efficient? In the study of Schepens et. Al. in 2003, it focused on the cost efficiency and impact of the Cyber Defense Course. The rough estimate of conducting the course would be $20,000 for all the hardware and software components. (Schepens, Schafer, Surdu, Ragsdale, 2002) Other costs were not yet included like technical monitoring and repair. The question rising would be if the hefty cost is worth the increase in education effectiveness. (Tomes, 2000) There is an eminent intuitive interest to the concept that innovative experience provided by the Information Assurance course. When cadets essentially execute an attack, they must also depict how they would guard against several attacks. The twofold function of the course instigates self learning since technology constantly upgrade. The course trains a studentââ¬â¢s critical, analytic and amalgamating skills. (Schepens, et al., 2002) Some remarks of the students under the first Information Assurance course said that it was a fresh breath of air and that it was invigorating to have hands down experience and learning about cyber defense. Another comment of the course is that it teaches them the indispensable lesson that security is an immense field to defend and it continuously expands. (Tomes, 2000) In terms of the cost efficiency, the starting point of the Information Assurance program was expensive and was shouldered by the National Security Agency. (Augustine Dodge, 2006) In time, more military schools implemented the Information Assurance course. With additional military school consumers, the expenditure of the course basically lessened. In another evaluation for cost efficiency of the Cyber Defense Program, it was noted that military schools can use open source software. Open source is computer software for which the source code and further rights are presented beneath a software license that convenes the open source characterization. (Gourley, 2009) This characterization allows consumers to utilize, alter and develop the software and restructure it in modified or unmodified figure. An example of Open Source software is Linux and an example of Closed Source software is Microsoft. Open Source software is continuously accessible for assessment, and in the majority situations it is cultivated in an open, public, mutual approach. Open source does not just signify approach to the source code, but also give the user the power to develop something greater. (Gourley, 2009) Another feature of open source is its inexpensive price. Since most of the open source software is not in the mainstream of the market, their prices are lower than the trendy closed source software. Therefore, the use of open source software can lower the cost of the Information Assurance course. (Gourley, 2009) One downfall for the use of open source software is its advance interface for beginners. It is not so much user friendly than its rival closed software. (Gourley, 2009) In a military school that is starting Information Assurance, its students might not be that specialized with open source software. Nevertheless, the application of open source software in Information Assurance can be cost minimization scheme. Is the Cyber Defense Program time effective? In another study, the time effectiveness of the program was evaluated. The Cyber Defense Program demonstrated numeral of effective dealings utilized to preclude, or perceive, compromises. However, it is substantial that the application and execution of the course require more time to operate than regular military courses. (Mullins, Lacey, Mills, 2007) Also, scrupulously understanding attacks and defends were essential for safe security operations, but requiring a tedious learning process. Furthermore, it was imperative to make sure the systems applied have been correctly patched and renewed. It should be mentioned that in real-world procedures, patch management is a multifaceted matter that needs receptiveness and attention. This makes additional time consumption. Another time spending effect of the Cyber Defense Program is the time and resource intensity for the workload of the instructor. (Mullins, et al., 2007) However, even with time consuming activities of the course, it is still being managed. Military schools somehow compress the activities to course to conserve time consumption. The faculty of the military schools that has Information Assurance courses remark that the additional load given are worth the excellent performance of the students. Another remarkable activity of the course that improves time utilization is the further engagement in Cyber Defense Exercise between different schools. (Adams, Lacey, Gavas, Leblanc, 2009) This was mentioned earlier in the paper in which military schools take part in the annual Information Warfare. The warfare investigates the effectiveness and time efficiency of the Information Assurance course in the schools. Cadets will build up their own team and represent their school. The Information Warfare improves time effectiveness of the course because it compels the cadets to attack and defend as fast as possible in a certain given time. The improvemen t in time effectiveness in the course is a huge factor that helps the military schools to win the competition. In a given school year, cadets with potential skills in Information Assurance are time pressured to create attacks and concoct defensive schemes in a nick of time. (Adams, et al., 2009) The inclusiveness of time effectiveness in course permeates the time saving scheme in the program. In a recent Information Warfare between several military schools, the winner of the competition was the school that attacked and defended in the most number of times in a given time limit.à (Mullins, et al., 2007) Therefore, it can be deduced that time effectiveness is correlated with successful Information Assurance courses. Table 1. 2006 Cyber Defense Exercise Results School Score AFIT 50,550 USAFA 48,425 USMA 46,600 USNA 45,650 USCGA 44,100 USMMA 43,725 (Mullins, et al., 2007) Results and Conclusion The following evaluations were clear in addressing two vital concerns about the Cyber Defense Program which is cost efficiency and time effectiveness. In the cost effectiveness of the program, the evaluations clearly pointed out that the Cyber Defense Program is costly. A plausible solution for this predicament would be the increase of Information Assurance course military school users. The greater the consumers of the course would result into a reduced expenditure. Therefore, the Information Assurance course should be promoted to the different military schools around the United States. Also, it can be opened that the Information Assurance course should not be held back to military schools exclusively. Other school should also access the course for further learning improvement. Another concern of the evaluations would be the use of cheaper software. The open source software is relatively economical than the other commercially closed software. The problem concerned with open source software for the Information Assurance course would be its advanced interface in which new users of the program might not easily familiarize with the system compared to the other software. Therefore, it should be recommended that open source software may be used by military schools that have an established experience in Information Assurance to lessen expenditure and greater progress into advance technical systems. Time effectiveness was also addressed as an issue on the Information Assurance course. The technicality and complexity of the program spends much time. In a certain evaluation, it was seen that the military school faculty can still cope-up with the additional time effort as long as they can see the improvement in the cadets. Another activity that boosts the time effectiveness of the course is the construction of Cyber Defense Exercise between military schools. It inculcates time effectiveness in the students in attacking and defending during a certain period of time. However, it was not yet certain whether an increase in the budget of the Information Assurance course would increase the effectiveness of the program. Therefore the creation of competitive and spirited competition should be increased because it can improve the time effectiveness of the course. In all the gathered evaluations for Cyber Defense Program, it was unanimous that the students positively liked the program and has increased their analytic and cognitive skills. In a generalization, even with some unresolved matters, the effectiveness of the program is unwavering. The benefits produced by the program outweigh its costs. Therefore, the Cyber Defense Program should continue and grow. REFERENCES Adams, W. J., Lacey, T., Gavas, E., Leblanc, S. P. (2009).

Augustus and Pax Romana Essay Example
Augustus and Pax Romana Essay Example Augustus and Pax Romana Paper Augustus and Pax Romana Paper Name: Course: Tutor: Date: Augustus and Pax Romana Pax Romana is a Latin word that literally means the Roman Peace. It was a period in the Roman Empire that had relative peace. There was minimal military force expansion and this period lasted for approximately two hundred years. The leader who is attributed to having established this period was Caesar Augustus. Through this period, there was economic growth, art and architectural development and the commerce flourished. Augustus contribution to the Pax Romana period became a foundation to the Western rule in the past and Today. As earlier identified, Augustus is mostly credited for establishing this period. This period began after he won the Battle of Actium by defeating Marc Anthony. Since he could not succeed using the one-man rule, he formed a junta of which he placed himself as the front man. The junta was formed by joining the two great military magnates. This was a form of eliminating civil war. Even though this did not mark the end of civil wars (there was a civil war in the Alps and Spain) and Pax Romana did not begin immediately, it paved the way for its existence. By closing the Gates of Janus (Roman ceremony marking world peace) thrice, the Period slowly came into being. Through propaganda, he was able to convince the citizens that peace was better and more flourishing than obtaining wealth through dangerous wars (Matz Lawrence 150). The above only took place between the 27 B.C and 14 AD, the period, which Augustus ruled. Nevertheless, this strong foundation made this period last for another 160years. Due to its strong foundation, the period successful lasted through the Commodus rule. This is because he misruled despotically and with dispendious excesses. This ruling made the roman politics be unstable in the middle of the Germanic invasions. When Cosmmodus was assassinated, the crisis was resolved, and the peace period continued. This period was faced by many challenges even by the succeeding rulers. However, most of them followed the actions of Augustus in order to maintain this peace. When a crisis came up they sometimes made lavish ceremonies in order to close the Gates of Janus. In other cases, coins with Pax on the reverse were issued to the citizens as a way of encouraging them to choose peace over war. Literature that advocated the advantages of the Pax Romana were also established. All these enabled this era to last until the fall of the Julio-Claudian and the Nero line. It is important to note that this period was called the peace period because there were law and civil order thus lesser civil wars and other wars that came due to lack of these concepts. Due to this great foundation, most of the Western laws are formed from the Roman law. The founders of the United States spoke of establishing the Augustan Age when they decided to establish the Office of the president (Matz Lawrence 216). This meant that they recognized the works done by this emperor, the effectiveness of his concepts during his time and the centuries after. Caesar Augustus contributions to the Pax Romana were not only effective during his reign, but they were also effective in the succeeding reigns. They are greatly recognized in the modern ruling and thus incorporated in the making of some European laws. Although there are other rulers who played their role in making sure that this period was established for the longest time, he laid down the basics and the concepts. His persistent nature and propaganda were also helpful in making sure that the people got a hold of his concepts, even though they were not effected immediately as expected.

The Effects Of Mobile Phones Essay Example | Topics and Well Written Essays - 500 words
The Effects Of Mobile Phones - Essay Example Health Problems According to BBC News (2002), studies have linked the use of mobile phones with headaches, hotspots in the brain as well as cancer. However, Foster and Moulder (2000) indicated that lawsuits that have been filed in courts in the United States have not been able to provide any concrete evidence of this claim as there has been no proven associated increase in cancer among the population and the complainants have not been able to provide any evidence to substantiate that their case is caused by the use of mobile phones. ARPHANSA (n.d.) has also indicated that although there is a possibility of a small risk, there is no clear evidence in the scientific literature to suggest that it poses a long-term health hazard. Teenagers are high users of mobile phones. Studies carried out in the U.K. have found that approximately 80% of 11 to 14 year olds own a mobile phone (The Institute of Science in Society n.d.). Studies also indicate that prolonged use may cause teenage brains to age prematurely (The Institute of Science in Society n.d.). Behavioral Problems in Young Children According to Divan et al (2010), prenatal and postnatal exposures to mobile phones have resulted in behavioral problems in young children.

Illicit Trafficking of All Types Research Paper
Illicit Trafficking of All Types - Research Paper Example The activities along these ports have attracted human traffickers, drug barons and even terrorists. Many South American illegal goods find their way in Africa through the ports in the Indian Ocean. This may be attributed to corruption and poor custom laws and regulations (Ploch, 2010). With the effects of the trafficking activities affecting many international countries the sensitivity of the matter has increased. In this paper I will focus on Kenya activities along the Kenyan coast. The paper will focus on human, drugs and weapon trafficking in Kenya. Additionally, it will focus on the effects of these activities in the country and the international community. The paper will have an insight on how the trafficking activities affect the United States. Kenyaââ¬â¢s port city of Mombasa is one of the largest cities along the coast of the horn of Africa. Neighboring countries like Uganda and Rwanda use the port for export purposes since they are landlocked. This has made the port becom e the largest port in East Africa. This has attracted interests from many illegal stakeholders. First on focus is the issue of weapon trafficking. According to Shelly (2010) about 5,000 illegal firearms enter the country on an annual basis. These weapons find their way into the hands of interested people in the country. They are later sold at cheaper prices to pastoralist communities and other illegal gangs. In other instances, the firearms end up in other neighboring countries. Apart from the trafficking of firearms, explosive devices in Kenya are also on the increase. During this year, the country has had about seven explosive attacks in major cities. The explosives used in the scenes are said to have originated from a foreign country. Most firearms in Kenya are usually from the neighboring Somalia or destined to Somalia. Somalia is an unstable country, hence, traffickers find it an easier route to smuggle weapons to Kenya. Weapon trafficking in Kenya also involves top government officials. These powerful individuals are usually the masterminds of trafficking activities in the country. This hinders any investigative procedures from taking place. Weapon trafficking in Kenya has greatly affected the United States. In the year 1998 the US embassy was a main target in a terrorist attack in Nairobi. The terrorist attack was the worst attack experienced in the country. The Al- Qaeda group claimed responsibility for the attack and said it was aimed at destroying the US embassy. This was evidence that weapon trafficking in the country is a more complicated and strategized crime (Clinton, 2010). The United States government had to highly compensate the victims of the attack. Drug trafficking in Kenya has also been an emerging issue as far legality is concerned. Through its coastal town Mombasa, drugs enter the country from South American countries. Large consignments of drugs find their way to Kenya through various entry points. Entry points include border with neigh boring countries, through airports and majorly through the port of Mombasa. In the coastal city, many youths are now in rehabilitation centers after being exposed to drugs at a very young age. Many youths turn into small scale peddlers. They sell the drugs to school students and other young people. This has destroyed the young generation in Kenyan coastal region. Just like the weapon trafficking menace, powerful personalities are greatly involved in the smuggling of drugs into the country (Ploch, 2010). From the coastal

Salem Witch Trials and Vengeance Essay Example for Free
Salem Witch Trials and Vengeance Essay In Arthur Millers play, The Crucible, vengeance plays a major role in the actions of the characters through the witchcraft trials in the Puritan village of Salem, Massachusetts in 1692. Anger, jealousy, rejection, and betrayal all occur throughout the play and are all things that could provoke someone to seek vengeance on someone else. Abigail Williams, niece of Reverend Parris, is one of the main characters who is very guilty of wanting vengeance on others throughout The Crucible. In Act I, the reader gets a taste of who each character is and the previous troubles theyve had with each other at Reverend Parris house, where many of the characters have come to check on Betty who is supposedly ill after a night of dancing in the woods. Abigail shows that she does not favor Elizabeth Proctor when Parris asks her why she was no longer a servant for the Proctor household. Abigail replied to him, ââ¬Å"She hates me, uncle, she must, for I would not be her slave. Its a bitter woman, a lying, cold, sniveling woman, and I will not work for such a woman! â⬠(Miller 1240). This statement foreshadows that there was an incident between the Proctors and Abigail while she was working for them. Then once Abigail and John Proctor are alone in Bettys room, she speaks to him about his affair with her and how she waits for him every night. He then tells her, ââ¬Å"Abby, I may think of you softly from time to time. But I will cut off my hand before Ill ever reach for you again. Wipe it out of mind. We never touched, Abby. â⬠(Miller 1246). This greatly angered Abigail. Feeling a sense of rejection, she decided that she needed to seek vengeance on Elizabeth, since she is unable to be with John. Also, when Abigail was alone with Betty and Mary Warren, she threatened to get vengeance on them if either of them turned her in. ââ¬Å"And mark this. Let either of you breathe a word, or the edge of a word, about the other things, and I will come to you in the black of some terrible night and I will bring a pointy reckoning that will shudder you. And you know I can do it; I saw Indians smash my dear parents heads on the pillow next to mine and I have seen some reddish work done at night, and I can make you wish you had never seen the sun go down! â⬠(Miller 1244). After reading about Abigails anger towards the other characters, it is very evident that she will be a major problem throughout the rest of the play. Knowing that Abigail was very angry about John Proctor, it was like her character to get accusations in order against Elizabeth Proctor. Not only did Abigail hate Elizabeth, but she also saw her as the only thing holding John back from being with her, which is selfish, yet typical. In Act II John and Elizabeth end up arguing about him going into Salem that day, which turned into an argument about Johns affair with Abigail. It is then, that Mary Warren comes home with a poppet to give to Elizabeth as a gift. Once Mary informs them that Elizabeths name was mentioned in court she automatically knows that Abigail has to be behind this searching for vengeance. ââ¬Å"It is her dearest hope, John, I know it. There be a thousand names; why does she call mine? There be a certain danger in calling such a name I am no Goody Good that sleeps in ditches, nor Osburn, drunk and half-witted. Shed dare not call out such a farmers wife but there be monstrous profit in it. She thinks to take my place, John. â⬠(Miller 1274). When Elizabeth was about to get taken away after finding the poppet, John was angry and said, ââ¬Å"If she is innocent! Why do you never wonder if Parris be innocent, or Abigail? Is the accuser always holy now? Were they born this morning as clean as Gods fingers? Ill tell you whats walking Salem vengeance is walking Salem. We are what we always were in Salem, but now the little crazy children are jangling the keys of the kingdom, and common vengeance writes the law! This warrants vengeance! Ill not give my wife to vengeance! â⬠(Miller 1283). Act III of The Crucible takes place in court and John Proctor ends up confessing to having an affair with Abigail when he says, ââ¬Å"She used to serve me in my house, sir. A man may think God sleeps, but God sees everything. I know it now. I beg you, sir, I beg you see her what she is She thinks to dance with me on my wifes grave! And well she might, for I thought of her softly. God help me, I lusted, and there is a promise in such sweat. But it is a whores vengeanceâ⬠(Miller 1309). Not only did this cause an emotional breakdown for John, it also disclosed that Abigail only set Elizabeth up with the needle in the poppet to get her out of the way so she could be with John. Even though Abigail had managed to get vengeance on Elizabeth Proctor, she still did not reach her goal of being with John Proctor. Instead, all of her conniving tricks, ridiculous accusing, ealousy, lying and pretending led John to his death; leaving Abigail Williams with nothing but ââ¬Å"his nameâ⬠. In this play, the salvation of innocent people has been sacrificed for the satisfaction of one seeking vengeance on another; innocent or not, confession was the only way to get out of death. It goes to show that vengeance can go a long way if the hatred, jealousy and anger is strong enough. In Arthur Millers play, The Crucible, vengeance plays a major role in the actions of the characters through the witchcraft trials in the Puritan village of Salem, Massachusetts in 1692.

The Benefits of Environmentally Responsible Residential Housing Essays
The Benefits of Environmentally Responsible Residential Housing à Beginning in the 1960s, our society has become increasingly aware of mankindââ¬â¢s negative impact on the earth. We have heard more about topics such as pollution, water contamination, Acid Rain, and Global Warming. All of these environmental concerns have displayed a need for more environmentally sensitive development. Environmentally responsible residential development is defined by Brewster as, "the production of building and communities that conserve resources and reduce waste through more efficient use of materials, energy, and water; that are more durable and useful; and that are designed for adaptive use or the recycling of their materials" (33). By definition alone, this type of development fits the description of sensitive development. I propose that we, as a society, must provide more incentives to encourage development such as environmentally responsible residential houses, because it will help reduce pollution, conserve limited and natural resources, and ensure a susta inable future. The need for such housing must be established with consumers before more environmentally responsible houses are demanded in the market. One reason for this type of building, would be to properly address the problems of the energy crisis. The Oxford English Dictionary defines the energy crisis as, "a serious shortage of energy-producing fuels" (Simpson 5:241). Today, we are consuming our fossil fuels at ten million times the rate they are produced naturally (Griffin 4). At this rate, we will eventually deplete all of our fossil fuels, such as coal, oil, and natural gases. The energy crisis also addresses another reason to build environmentally responsible development, which... ...itute, 1974. Loeb, Penny.

Substitution and Income Effects of the Working Tax Credit on Labour Supply
Labour essay: Having considered the implications for the WTC, we can now analyse the effects of the policy on labour supply by determining the substitution and income effects. Itââ¬â¢s clear that the effect of the working tax credit on work behaviour depends upon how much a worker is currently working. To analyse these effects we will only look at one type of individual; a lone parent in the labour force. This will simplify our analysis such that we can divide the diagram below into 3 sections and describe the effects separately. draw:frame} Figure 1: Diagram showing how the imposition of the WTC affects the individuals labour supply decision When the lone parent is either not working at all, or working less than 16 hours (Labelled A in the diagram), her current wage rate and therefore income is unaffected by the WTC. This is simply because they have not yet received any tax credit and therefore have no added incentives to work. However, if they work over16 hours, the programme wi ll raise their overall take home wage as they receive a lump sum payment, shown by the first vertical blue line. Therefore, at this low level of work, there is a very small, or 0, income effect, and a positive substitution effect, thus increasing the individualââ¬â¢s labour supply. These effects are the same as would be under an increase in the wage rate, shown diagrammatically in Figure 2. {draw:frame} Figure 2: Diagram showing the effects of a wage increase The movement around the original indifference curve from A to C is the substitution effect; this arises due the change in price of leisure relative to hours of work, holding utility as constant. As the wage rate has increased the opportunity cost of leisure opposed to work has risen. The substitution effect encourages the worker to decrease his hours of leisure. The movement from C to B donates the income effect illustrating the workers response to an increase in real income. Overall, the substitution effect dominates the income effect and therefore increases labour supply from L1 to L2. There is also the possibility that the income effect may overpower the substitution effect resulting in a decrease in the supply of labour. However, this depends on the position of the indifference curves, hence the workerââ¬â¢s preferences for work and leisure. On the other hand, it is unlikely at this low wage rate for the worker to choose leisure over the opportunity to earn a higher wage. Section ââ¬ËCââ¬â¢ of our WTC diagram shows the area at which an individual works more than 30 hours. The workerââ¬â¢s net income is now higher at this point, however the workerââ¬â¢s marginal wage is lower which is demonstrated by the gradient of the WTC line being shallower than gradient of the No WTC line. The Substitution and Income effects here are the same as would be with a decrease in wage. Both the Income and substitution effects work together to reduce the amount of labour; shown in Figure 3: {draw:frame} Figure 3: Diagram showing the effects of a wage decrease The substitution effect is shown by the movement around the old indifference curve, from A to C. The income effect is shown by the movement from A to B. Although the substitution effect is stronger, both effects work together to reduce the hours of work from L1 to L3. Lastly, section ââ¬ËBââ¬â¢ represents the area at which an individual works between 16 and 30 hours. Here, the effects of the WTC on labour supply are much more complex. Despite the gradient of the WTC line being the same as section C, this time there is the possibility of increasing work to above 30 hours and receiving the additional payment. This therefore results in lone parents bunching around the 16 and 30 hour marks in order to gain the greatest benefit from the WTC payment. Some will therefore substitute leisure for work and work longer hours to gain the additional bonus at 30 hours, whilst others will choose to forgo work for leisure and be content with the benefit of working over 16 hours.
