Cyberphysical Security in Networked Control †MyAssignmenthelp.com

Question: Discuss about the Cyberphysical Security in Networked Control. Answer: Introduction Information is considered to be the most valued asset of any sector. Information is susceptible to various types of risks as well as threats. With the emergence of information technology, the cyber threats are increasing at a fast pace. Information security focuses on protecting the valuable and sensitive data of an organization. Information security is involved in protecting the integrity, confidentiality and availability of the information. Banking sectors deal with financial data that needs to be protected. Nabil Bank is known as the first commercial private bank of Nepal (Nabilbank.com 2017). Nabil Bank is involved in providing wide range of banking services via its 52 representation points. This report discusses and plans a security program for providing information security to Nabil Bank. It tries to improve the present security structure of Nabil Bank. This report gives a brief overview of information security. It gives suggestion about the kinds of security models that can be adopted by Nabil Bank for better and secure operations. Threat identification along with risk assessment is also carried out in this report. This report discusses about the ISO standards as well as modes that will be suitable for Nabil Bank with proper reasoning. The training requirements are also provided in this report for adopting security programs in an effective manner. This report recommends certain steps and procedures that can be taken by Nabil bank for improving its security infrastructure and for making the system of information security strong. Information security can be considered to be a practice of defending and protecting information from any kind of unauthorized access, misuse, disclosure, modification and disruption (Vacca 2012). The modern generation is completely dependent on the information and communication technology for confidential as well as commercial purposes. There are several risks as well as threats that are associated with information technology like safety risk, environmental risk, physical risk and financial risk. Security concerns that are related to ICT are gaining major importance with time. All the organizations in every sector face some kind of security issues (Webb et al. 2014). Strong information security structure as well as risks can be adopted in an organization to protect it from risks and threats. Risks can be mitigated and prevented by several methods and techniques. Information security has certain aspects like confidentiality, availability and integrity. When the information cannot be accessed by any unauthorized user then the confidential aspect of information is achieved (Von Solms and Van Niekerk 2013). When the information cannot be misused, destructed or modified by an attacker or user than the integrity of the information is maintained. When the right information is available to the right or authorized person at the correct time with no such interference or obstruction then the availability of information is achieved. Banking sectors have been a major target for the hackers, crackers as well as the cyber criminals. Information security aims at identifying the risks and mitigating it for protecting sensitive information. Current Security Situation and Titles of the Security Personnel Nabil Bank was founded in July, 1984. Their main objective is to extend the services of modern banking to different sectors of the society. Nabil Bank provides several banking and financial services via its 52 representation points. It has introduced several innovative and modern marketing concepts and products in banking sector. Their main objective is customer satisfaction. Highly qualified personnel are responsible for managing the daily operations. Sensitive financial information is handled by the bank. Risk management is carried out by highly experienced and qualifies management team. Nabil Bank is totally equipped with advanced technology that consists of banking software of international standard for supporting E-transactions and E-channels. Their aim is to provide a complete and secure financial solution to their customers. The risk management team is highly efficient in assessing the risk and providing information security to the organization (Sandberg, Amin and Johansson 20 15). There are many security personnel present in the risk management team. They are as follows: Chief Risk Officer: The main duty of the Chief Risk Officer is to implement risk functions, tools as well as systems for identifying, assessing, measuring, monitoring and reporting risks. They identify main risk areas and enhance the function of security architect. They are also responsible for implementing security program. Head of Credit Risk Management: They are responsible for implementing procedures and policies for the purpose of reducing credit risk. They are also involved in building financial models that have the capability to predict any type of credit risk that can affect the organization. The credit risk management team reports to their head regarding daily operations and activities. Senior Credit Analyst: They are responsible for reviewing and assessing financial history of a company or an individual for the purpose of determining whether the candidate is eligible for getting loan. They evaluate financial statements like balance sheets as well as income statements for understanding the default risk level. Compliance and Operational Risk Manager: They are responsible for handling the risk related to legal sanctions, financial loss or loss of banks reputation. They ensure that the bank complies with the government laws, standards and its own code of ethics and conducts. They also manage any type of risk arising because of failure of internal processes, systems, people as well as external events. Risk Assessment and Threat Identification Risk assessment deals with a number of steps and procedures for understanding the asset values, possible threats, system vulnerabilities, and predictable impacts of threats along with the likelihood of threats (Kit et al. 2014). Risk can be defined as vulnerability functions as well as the expected impacts of threats. Risk depends on the probability of the occurrence of threat. System characterization is the first step in risk assessment. Information about the software and hardware involved is initially found out (Aloini, Dulmin and Mininno 2012). NIST framework of risk management involves assessment of risk after all the risks have been framed. This framework integrates business processes, company goals, mission, SDLC processes and information security infrastructure for effective risk assessment. The methodology of risk assessment includes a process, risk model, an approach for assessment and analysis approach (Lo and Chen 2012). After risk identification is carried out, the risks are monitored. ENISA framework will be effective in the E-transaction processes of Nabil Bank for the purpose of assessing risks (Theoharidou, Mylonas and Gritzalis 2012). This model identifies the risk and analyses it for the purpose of evaluation. Information security can be enhanced in an organization only by identifying the possible threats and risks. Threat can be considered to be a potential for some kind of trouble or damage to IT infrastructure. After proper identification of threats a well planned security program can be carried out in order to protect the bank from any data and security breach. Nabil Bank provides several financial and banking services. It also provides online banking facilities to the customers. There are two broad categories of threats that are identified initially. These are the internal and external threats. Internal threats: Business practices and processes of a financial institute have a huge influence on internal threats. If more number of employees is able to access sensitive customer information then the probability of threats will be more. The intensity of internal threats is less as they are under the control of the bank. External threats: These threats have a greater intensity as they are not under the control of the bank. External threats can be reviewed by listing the reasons and ways in which personal data can be accessed, identifying the ways by which the banks system is connected to outside world via emails and networks, identifying service providers that have access to the data. Then the exposure of the threat is identified. Some of the threats that have been identified in the internet banking system of Nabil Bank are phishing, spyware, viruses, Trojan horses as well as key loggers. In phishing attack hoax mails are used for committing a fraud activity (Hong 2012). Online thieves can steal sensitive data of the customers to misuse it. Spyware is a type of malicious software that collects valuable information of the users in a secretive manner for misusing and modifying it (Giannetsos and Dimitriou 2013). Viruses can get attached to another program like spreadsheets for replicating itself. Trojan horses are another type of threat where an application acts like a secure application and harms the system in which it is downloaded or injected. Key logger software is considered to be the most harmful threat of Nabil Bank (Dadkhah and Jazi 2014). If key logger software is installed in the electronic device of the customer from where the customer accesses online banking services, then it tracks all the informati on that is used by the customers. This information can be used by the attackers in order to steal money from the bank. The financial database of the bank can be hacked to access sensitive financial data (Martins, C., Oliveira and Popovi? 2014). Deliberate and external threats are extremely harmful for the banking sector as it causes huge financial loss. After identifying the threats, their exposure must be determined to rank them based on their intensity. This will be extremely helpful for the bank to mitigate risk in an efficient manner. Security Models Security models are responsible for providing standards for the purpose of comparison and reference. Nabil Bank uses the NIST access control model for the purpose of identification of access mechanism that is used in different levels that exist in the bank. Management level is involved in dealing with information that will help in the strategic planning process. The level that deals with administration work will be responsible for controlling operational data. The technical layer of the bank deals with daily operational data that is needed for running the business. NIST framework is responsible for describing the present cyber security posture, their target state, find out ways to improve risk management and fosters the process of communication between the external and internal stakeholders of the bank. The present risk management procedure is not replaced when the bank uses NIST framework. Rather the NIST framework tries to complement the present security structure (Chang, Kuo and Ramachandran 2016). The bank can use its current structure and leverage NIST framework for the purpose of identifying opportunities for improving the current risk security management. The security models of NIST framework will be highly beneficial for Nabil Bank as their documents are available at free of cost. It can also be updated by government. Risk assessment guidelines, security plans and privacy control plans are provided NIST framework (Malik and Nazir 2012). Strong information security policies can be implemented for protecting the banks valuable information . Development of Security Program Nabil Bank is a large sized company having 52 points of representation across Nepal. The organization structure that is present in the bank is hierarchical in nature. The organization has code of ethics and conducts incorporated in its culture. The main objective of the bank is to provide a single and secure financial solution to its customers. Nabil Bank gives first priority to its customer. The employees follow a code of ethics in the organization (Peltier 2016). They act in an honest manner to protect the interest of their clients (Hu et al. 2012). The bank takes major action against any employee who commits any misconduct. Strong information security policies can be implemented for protecting the banks valuable information. A well planned security program can be effective for protecting the bank from any security risks and threats. Financial data breach will cause loss to the clients and also will affect the reputation of the bank. The following steps can be taken in order to dev elop an efficient security program: Risk assessment: The first step in this process is to identify what department deals with what information. The bank also needs to find out who has access to what sensitive information. The second step will be to identify external and internal threats and determine its probability of occurrence. The last step is to determine whether the existing policies are adequate for protecting the information. Current policy adjustments: A security policy must be designed to protect the customer information. This policy must be approved by the board of directors in order to carry enhance the information security of the bank. Security control design: The management should focus on developing security control plans for all the business units. There must be security guidelines present. Access controls need to be designed where authentication procedures like passwords, PINs, electronic tokens are used. Biometric identification and firewalls can be implemented for protecting the databases that store sensitive financial data. The networks can be protected by implementing firewalls. The customer details can be encrypted to protect it from any unauthorized access. Response plan: The management team must develop and design a response plan for overcoming a security breach situation. The person who is in charge of maintaining customer information must design this plan. It must be well written. The plan needs to include the contact details of law agencies for taking appropriate steps. Service provider: The contract between the bank and service provider must contain effective response plans. The bank must ensure that the contract contains appropriate standards for information security. Testing: The testing of the security controls and plans must be done to make sure that the bank is well protected from any type of security threat and risk (Shackelford et al. 2015). The parties involved in the contract must conduct control testing. They must conduct ethical hacking to find out the effectiveness of the security policies and plans. Roles and Responsibilities Chief Risk Officer: The main duty of the Chief Risk Officer is to implement risk functions, tools as well as systems for identifying, assessing, measuring, monitoring and reporting risks. They identify main risk areas and enhance the function of security architect. They are also responsible for implementing security program. Security Manager: The role of the security manager is to collect and utilize information in an effective manner to achieve the goal of the organization. They are responsible for proper communication of information among various layers. Senior Credit Analyst: They are responsible for reviewing and assessing financial history of a company or an individual for the purpose of determining whether the candidate is eligible for getting loan. They evaluate financial statements like balance sheets as well as income statements for understanding the default risk level. Information security of Nabil Bank can be improved by adding more designations and roles so that there is no overlap of responsibilities of the employees (Ahmad, Maynard and Park 2014). Some of the new titles that can play an effective role in improving information security are: Technical security manager: The technical aspects of security will be looked after by these managers. They will be involved in firewall implementation and encryption processes. Program security manager: The third pert or vendor risks can be evaluated by these managers. CISO: The whole security policies can be looked after by CISO. CISO can take the responsibility of design strong security policies for the organization. Source code manager: The source codes can be reviewed by these managers for detecting any type of vulnerability. There can be many specialized roles like virus technicians whose responsibility will be to detect new virus as well as develop a defense plan to fight the virus. Training Requirements The employees of Nabil Bank must be aware of the need of a strong information security program. Employee training can be considered to be a critical component for the information security of bank. Management must document the information regarding which employee has access to what valuable information of the customers (Hu et al. 2012). The employees must be made aware of the security policies of the bank. They must be trained to identify valuable customer information. Employees must be given training on how to implement the written policies that governs the disclosure of the information of the customers (Lebek et al. 2013). There need to be regular meetings to discuss new policies and modify existing policies for improving the present information security policy. ISO Standards and Models ISO model is used in most of the industries. ISO standards provide a common base to all the organizations in order to develop security standards and policies (Disterer 2013). Organizations are able to develop inter organizational deals by using ISO standards. ISO/IEC 27001: This standard helps in implementing ISO/IEC 27002 in order to set up ISMS (Susanto, Almunawar and Tuan 2012). ISO/IEC 27002: This standard addresses the security needs of an organization. It also helps in developing security policies (Ramanauskaite et al. 2013). ISO model is well suited for Nabil Bank because it will assist the bank in developing management system for managing information security. The ENISA model can also be suitable for Nabil Bank for the purpose of securing the E-transaction and E-channel. Conclusion This report concluded that Nabil Bank can improve its information security by adopting a well defined security program. This report discussed about the critical factors of information security like confidentiality, availability and integrity. It said that the breach of data and information security can lead to serious and potential losses. The main purpose of assessing risk is to identify organizational threats and vulnerabilities. Internal threats can be identified by finding out which staff has access to which information and overlapping information. It pointed out that the security system of the bank is accessed by an unauthorized outsider then this result in external threats. It gave a description about the security program that can be adopted by Nabil Bank. This report discussed about the current roles and suggested an improvement plan for making the information security of the organization strong. It suggested that the employees must be made aware of the security policies of th e bank. This report concluded that ISO model is suitable for the bank and ENISA model is suitable for its electronic transaction system. The advanced technologies as well the communication channels need to be protected from attackers. Recommendations Nabil Bank can secure its information and data from unauthorized access by following certain steps: Encryption: Financial data must be encrypted so that the hackers cannot get access to it. Employee training: Proper training must be imparted to the employees to enhance the information security. Updated software: Latest version of the software must be installed in the system. It must be updated regularly. Firewall: Firewall implementation will protect financial information from any external intrusion. References Ahmad, A., Maynard, S.B. and Park, S., 2014.

Should Tobacco Companies Be Held Responsible free essay sample

Should tobacco companies be held responsible for smoking-related illnesses and deaths? I. Introduction A. Should tobacco companies be held responsible for smoking related illnesses? In most cases I believe they should be held liable. Most Americans ask this question and want to know about cigarette companies and why they are allowed to keep selling these products that cause health problems. B. Most people that were smokers way back in the days before they actually had to label their products as unsafe and deadly. In the 70’s it was legal to purchase cigarettes as a teenager and the companies knew that their product was dangerous. Especially since minors were able to purchase these deadly products, they should be held accountable for those that began smoking in their teenage years and were sold to with the reassurance from the company and the government. II. Are the people responsible for their actions. A. Should the people make the sound choice to buy cigarettes who know the risk of smoking be held accountable for their health issues. We will write a custom essay sample on Should Tobacco Companies Be Held Responsible or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I believe it is called free will in this point being that people today know the repercussions of smoking. B. The fact that all tobacco companies today have to label the warnings on their products and people still make that choice to light up The general public has been well educated about the health risks of smoking, so people who smoke are fully informed about the possible consequences of their habit. Where will that lead our society, more than likely people will try and sue fast food companies for making them fat; trending on down to point the finger at all these companies for the bad choices they made. C. The people that actually started smoking before the surgeon general made these companies put warnings on their products; these people on the other hand did not know the facts about the health issues from smoking. In my eyes these people have every right to be angry or disgruntled with Big tobacco. These people are the victims of our society because they on the other hand like the present were not as informed of the health issues caused from smoking. So they should not be held liable because of these companies getting rich from other peoples suffering. III. Are the companies lying to the public. A. Do tobacco companies oversell and manipulate their products in order for consumers to keep smoking and should the government step in to control their habit? The tobacco industries have to put these labels because the government makes them do so. So now they have to make their product more appealing to offset their outcome of consuming their product. B. Tobacco companies are an evil industry and it’s not surprising they shredded documents to cover up strategic actions for addicting people to their cancer sticks. They try and promote their product as sexy but would rather make a buck from the deadly outcome from smoking their product.

Is Galileo considered a hero or anti-hero Essay Example

Is Galileo considered a hero or anti-hero? Paper Galileo Galilei, the central character of Brechts play, is known as one of the most famous scientists of all the times. He was one of the first to study in depth the universe and is known as the Father of Modern Science. I consider a hero a person noted for his acts of courage or noble purpose, especially one who has risked or sacrificed his/her life for the advantages of the human society. Galileo is shown as a hero on the first nine scenes of the play, for his courage to stand up the church and also for his passion and enthusiasm towards his aims. On the other hand, on the following scenes he is exposed with some characteristics of an anti-hero for his irreverence towards the church showing no respects whatsoever towards its privileged leaders and also for his coolness towards his daughter Virginia. Nevertheless, should Galileo be considered a hero or anti-hero for his actions? One of the most important characteristics that make Galileo a hero is his great determination and self-confidence in proving and demonstrating his ideas. He dedicated almost his entire life proving that his discoveries about the universe were right. Although, he knew that it would cost him a lot, he did not gave up the discoveries that he made. This is shown when he says: The sum of the angles in a triangle cannot be varied to suit the Vaticans convenience. P.68 This sentence shows that he refuses to ignore the changes for the sake of compromise on political and religious purposes. Even during the plague, he says: I didnt let the plague stop me from recording my observations, Pg.58 which shows his great determination towards his aim: scientific truth.

Galileo had a great courage shown by the fact that he was not afraid to put up with the opposition. While the Italian church, scientists and the whole population of that time still held their believes strongly on the Ptolemaic system (which placed the earth in the center of the universe), Galileo explored and found out that the Copernican system of heliocentricism was the real one. The church did not accept his findings because they would look very stupid and according to them it is better to be wrong than to question what they called it the Gods creation. They blindly believed that the earth was in the center of the universe and changing this would mean that people would no longer be in the center of gods eyes. This is strongly supported by Sagredo who says Do you imagine the Pope will hear the truth when you tell them hes wrong, and not just hear that hes wrong? Do you imagine he will merely note in his diary: January 10th 1610-got rid of heaven? Pg.33 The courage he showed to have had grew weaker when the Inquisition forced him to recant publicly his support of Copernicus. He gets arrested and recants his theories, an act this that shows some negative qualities because he refuses to sacrifice himself for the sake of scientific truth. Andrea furious when he finds out claims: Unhappy is the land, that has no heroes. Andrea feels betrayed by this renounce of Galileo who in this scene has a sound change in appearance, giving the impression of having an indecisive and weak character. Galileo is shown as a sensible and reasonable person because he understands that knowledge and particularly scientific discoveries take always time to be accepted. On one of the dialogues Galileo had with the Little Monk, he says Your Campagna peasants are paying for the wars which the representative of gentle Jesus is waging in Germany and Spain p.66 where he blames the church on spending money on wars and not on the well being of the peasant and therefore showing no respect and fairness for these poor and unfortunate people. He says that otherwise they could live in plenty and develop the virtues of happiness and prosperity. Pg.66 This noble character he shows towards the society, is sometimes counteracted by some weaknesses of his like the fact that he himself wasnt very sensible when he took the idea of the telescope from a Dutch scientist. Although, this was a smart and cunning way to earn money he is shown as a dishonest person behaving very hideously for stealing credit for ot hers discoveries. In his personal relations with others, Galileo is shown affectionate and sympathetic towards both Andrea and Mrs. Sarti. However, he alienates and doesnt give any attention to his daughter, Virginia treating her (from the start of the play) in a very careless way. When Virginia asks him if she can have a look at the telescope, Galileo answers in a very unkind way saying What for? Its not a toy, leaving Virginia without words. Here, he behaves in a very unfair and biased way towards Virginia because while he got Andrea out of the bed to show him his discoveries, he treats his daughter in very humiliating and cold manner by making it clear to her that he things she is not a clever person. Also, on the third scene Virginia tries to comfort her father who is worried weather the court will have him or not, by telling him Of course theyll have you, Father, with your new stars and all that. Galileo to this affectionate and caring encouragement answers in a very revolting and unpleasantly cold manner saying to her Run along to your mass. These acts show how unfair and unpleasantly cold he was to his daughter showing no attention and kindness whatsoever towards her. During the plague, Galileo asks a man to bring (me) a small book and bread while the man laughing tells him youll be lucky if u get bread. Here, Galileo is shown very self-centered and irrational because his request is very absurd in that circumstance. He is presented as a very passionate and dedicated person who spent almost his entire life proving that his ideas about the universe were right. He had a great desire for scientific research, a thing this that makes him even more a hero His great enthusiasm and passion towards science, is shown on the conversation he has with his friend Sagredo where he says: The lure of proof is too great. Nearly everyone succumbs to it, sooner or later we all do. Thinking is one of the chief pleasures of the human race. Pg.29 His enthusiasm towards science is also shown on the conversation he has with the Little Monk who suggests to Galileo that the truth will get through without pg.68 their help and Galileo responds the only truth that gets though will be what we force through and he later concludes And the worst thing is that what I know I have to tell people, like a lover, like a drunken, like a traitor, even knowing that it is an absolute vice and leads to disaster.Pg.68 At last, Galileo says I enjoy doing my stuff pg.17 showing once more his great satisfaction and determination towards the scientific research. Galileo has the ability to communicate and explain the most complex ideas with clarity and precision, things these that makes him a very comprehensive teacher. He is shown as a patient teacher and especially with Andrea to whom he teaches and explains all his discoveries in great details. He is also an enthusiastic teacher and this is shown when he praises Andrea for his comprehension saying Very well pg.10 and also giving Andrea good advices like you must learn to think cautiously. Pg.74 He was a great influence to Andrea and this is shown when Andrea quotes Galileos doctrine Someone who doesnt know the truth is just thick-headed. But someone who does knows it and calls it a lie is a crook. Pg. 75 and 95. He lives the discovering of these scientific researches in a very optimistic and joyful way saying: A new time has begun, a time its a pleasure to live in. pg.10 He understands however that knowledge takes always time to be accepted and this is shown when he says I believe in Humanity, which means to say I believe in human reason. If it werent for that belief each morning I wouldnt have the power to get out of bed. Pg.29 Here, Galileo shows his faith in human reason and his optimism that only reason will be able to get the peoples support for astronomical truth. Then, he drops a pebble on the ground (scene 3) showing people that if they believe in the force of gravity seeing it, then they should also believe in astronomy by proofing it. Scene 6 His strong optimism is also shown when he claims that the old days are over, and this is a new time.Pg.6 and also But now the word is thats how things are, but they wont stay like that,Pg.6 both of these showing his great optimism towards him aim but also show him as a combatant of truth and progressivism. In conclusion, I would like to state that in my opinion Galileo Galilei has shown qualities, merits, talent and contributions that make him a real hero. His outstanding abilities, his great courage, his faith in universal truth, his comprehension and reasoning of some complex ideas, his great social concerns of the time and his fighting for the progress in science make Galileo with no doubts a heroic character. His feeble points and weaknesses of his personality, which all humans have, are for the most part minor taking into account his merits. With his famous mythical saying Eppur si muove, (english-and yet it moves) he has remained for the last four centuries as a great hero, which symbolizes that the conviction and confidence towards the truth is stronger than any obstacle.

Importance of Natural Resources essay

Importance of Natural Resources essay Importance of Natural Resources essay Importance of Natural Resources essayNatural resources were historically an important condition of the successful development of countries. The disparity in the access to natural resources predetermined, to a significant extent, the socioeconomic disparity in the development of Northern countries and Southern ones. In fact, the economic and technological development of countries and the difference in their development was driven by the availability of natural resources, which stimulated the development of technology and, therefore, economic progress of those communities and countries, which benefited from the available natural resources and the backwardness of those countries and communities, which lacked natural resources. Even though today the process of globalization makes natural resources available worldwide, but the world economy still depends on natural resources and those countries, which have access to natural resources, especially fossil fuels, such as oil and gas, can keep progressing fast, while those, which have limited opportunities to use natural resources are doomed to backwardness.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Historically, natural resources played the role of the main driver of the economic development of nations (Deudney Flavin 114). For example, coal mining and the availability of iron to Great Britain allowed the country to become one of the leaders in the world economy and conduct its industrial revolution successfully. Similarly the availability of natural resources became the major condition of the successful economic and technological development of other powers, including the US, France, Germany and others (Kraft Kameniecky 158).At the same time, the significant role of natural resources as the major driver of the economic development becomes obvious, when the availability of natural resources, their use and historical socioeconomic and technological development of countries is compared. In this regard, the disparity b etween North and South is particularly obvious (McCormick 214). For example, early civilizations emerged in Northern hemisphere of the world basically due to the availability of natural resources, such as iron ore, for example, which allowed people to start making first tools as well as weapon. At this point, it is worth mentioning early civilizations in Egypt, Mesopotamia, Greece, India and China, which were all located in Northern hemisphere due to the available natural resources, such as iron ores (Best 664). For example, the beginning of the early production of bronze boosted the technological and economic development of those civilizations. The further introduction of iron, steel and other materials based on the use of natural resources accelerated their economic and technological development even more. Moreover, even the early settlement of people were determined by their natural environment and availability of natural resources, such as water and fertile soil, which people us ed for their regular life and basic needs.In the course of time, the role of natural resources increased even more because they became essential for the economic development of nations and fast technological progress (Lewis 245). At this point, it is possible to return to the time of the industrial revolution once again since the industrial revolution would be impossible without rich natural resources available to leading nations, such as Great Britain, France, Germany and the US (McCormick 148). The availability of such natural resources as coal and iron ore allowed them to boost their industrial production and develop transportation system, which, in its turn, accelerated trade within those countries as well as between those countries. At the same time, the rest of the world that had limited access to natural resources remained under-developed and suffered from technological and economic backwardness.The role of natural resources as the major driver of the economic and technologic al development became even more evident in the 20th century, when the traditional major powers, such as Great Britain, the US and others faced the tightening competition from the part of emerging economies of Southeast Asia (Kassman 149). In fact, the successful economic and technological development became possible due to the process of accelerated industrialization with the further transition to scientific, knowledge-based industries. The economic development of nations was therefore determined by the use of natural resources.In this respect, it is possible to refer to the level of the energy consumption in the world in the 20th century as well as today. The energy consumption is the major indicator of the level of economic and technological development of nations (Best 665). So far, the most developed nations have the highest level of the energy consumption, although they are trying to do their best to reduce this level to protect their environment and focus on the sustainable de velopment (McCormick 124). However, the energy is still an essential condition of the successful economic and technological development as well as it is an essential condition of the maintenance of the competitive position of nations in the global economy.At the same time, the lion share of energy in the world is generated by means of using natural resources, especially fossil fuels, like oil and gas. The share of renewable or alternative sources of energy is still low, whereas the major source of energy remains to be fossil fuels (McCormick 195). The availability of fossil fuels becomes the major factor that determines the competitive position of nations in the global economy. At this point, it is possible to refer to the crisis of the mid-1970s, which was triggered by the refusal of the Middle Eastern countries to sell oil at the low price (McCormick 202). This energy war resulted in a profound downturn in the economic development of the US and other well-developed nations. Today, the dependence of nations on fossil fuels is still very significant.On the other hand, the availability of oil and natural gas allow countries to boost their economic development, even if they are mere exporters of natural resources. At this point, it is possible to refer to countries of the Persian Gulf region, which used to be poor, under-developed nations, while today, they have become prosperous, technologically advanced nations that play an important part in the global economy. Their progress was the result of the oil export, which boosted their development and allowed them to increase their role in the world economy since they become the major suppliers of oil to the global market (McCormick 215). At any rate, decisions taken by Saudi Arabia and other oil exporting countries located in the Persian Gulf have a considerable impact on the oil price and situation in the global economy because oil is still the major source of energy, which is required for the fast economic develop ment and maintenance of stable functioning of well-developed economies. In such a way, the oil production and consumption has become the major driver of the economic development in the second half of the 20th century and still remains today. Hence, oil is one of the most valuable natural resources today, which is essential for the normal existence of the modern civilization because without oil the current level of the energy production would be impossible, while the modern civilization will not survive without the high level of the energy production at the moment.On the other hand, oil is just an example of the great significance of natural resources in the economic development of nations. The consumption of natural resources have become a norm that leads to the destructive impact of human economic activities as well as regular, everyday life activities on their environment (McCormick 156). For example, the consumption of timber has triggered the deforestation of many regions of the world that raises the problem of the threat to the natural environment. In addition, the use of natural resources leads to the pollution of the environment but the real problem of the modern world is the dilemma which virtually all countries face. On the one hand, they need natural resources to boost their economic and technological development, whereas, on the other hand, the use of natural resources leads to the further deterioration of the environmental situation.Thus, today, nations need to develop new policies oriented on the wise and effective use of natural resources. However, what proves to be beyond a doubt is the great role of natural resources in the development of nations. Historically, naturally resources played the key part in the economic and technological development of countries and today they still play the crucial part in the development of nations because they determine the competitive position of nations in the global economy.

Morality is internal as it reflects the habits, beliefs, culture, and religion of an individual while ethics are external since they are set by the profession. Morality is guided by the existing cultural norms while the ethics are guided by the legal and professional guidelines. Dutelle (2011) asserts that the morals are
