劳动者和劳役者的区别英文作文The world of work is a complex and multifaceted realm, encompassing a vast array of roles, responsibilities, and societal dynamics. At the heart of this intricate landscape lie two distinct groups - the workers and the laborers. While these terms are often used interchangeably, there are crucial distinctions that set them apart, both in terms of their nature and the societal implications they carry.At the most fundamental level, the primary difference between workers and laborers lies in the nature of their work and the skills required to perform it. Workers, by definition, are individuals who engage in skilled or specialized tasks that require a certain level of education, training, and expertise. They are often employed in professional or technical fields, such as engineering, accounting, or information technology, where their knowledge and problem-solving abilities are the driving force behind their contributions.In contrast, laborers are typically engaged in more physically demanding or manual tasks that require a lower level of specializedskills. These individuals may work in industries such as construction, manufacturing, or agriculture, where their primary role is to provide physical labor to support the overall production or construction process. While laborers may possess certain skills and experience, the emphasis is often on their physical capabilities rather than their intellectual or technical expertise.This distinction in the nature of work also translates into differences in the social and economic status of workers and laborers. Workers, with their specialized skills and educational backgrounds, are generally afforded a higher level of respect and social standing within the community. They are often seen as valuable assets to their employers and the broader economy, commanding higher salaries and enjoying greater job security and opportunities for advancement.In contrast, laborers, while essential to the functioning of many industries, are often perceived as interchangeable and replaceable. They may face challenges in terms of job stability, earning potential, and opportunities for professional growth. This, in turn, can contribute to a sense of marginalization and a perceived lack of social mobility, as laborers may find it more difficult to break out of the cycle of physical labor and low-income work.The differences between workers and laborers also have implications for the power dynamics within the workplace and the broadersociety. Workers, with their specialized skills and knowledge, often wield a greater degree of bargaining power and influence when it comes to negotiating wages, benefits, and working conditions. They may be better positioned to advocate for their interests and assert their rights, whether through collective bargaining or individual negotiations.Laborers, on the other hand, may face more significant challenges in this regard. Due to the perceived interchangeability of their roles and the relative abundance of unskilled labor in many regions, laborers may have less leverage when it comes to negotiating better working conditions or higher wages. This can lead to a power imbalance, where employers hold a greater degree of control over the lives and livelihoods of laborers.It is important to recognize that the distinction between workers and laborers is not absolute or rigid. In many cases, there is a spectrum of roles and occupations that exist between these two extremes, with individuals possessing a mix of specialized skills and physical labor capabilities. Additionally, the line between workers and laborers can become blurred as technological advancements and automation continue to transform the nature of work.Nonetheless, the fundamental differences between these two groups remain relevant and influential in shaping the social, economic, andpolitical dynamics of the modern workforce. Understanding and acknowledging these distinctions is crucial for addressing issues of equity, social mobility, and worker empowerment, as well as for developing policies and strategies that promote the well-being and advancement of all individuals engaged in the world of work.。

It marked a significant shift from an agrarian society to an industrial one, with profound impacts on society, economy, and technology.During the Industrial Revolution, there were several key technological advancements that played a crucial role in transforming the way goods were produced and transported. One of the most significant was the steam engine, which was developed by James Watt in the 18th century. This invention greatly increased the efficiency of factories and made it possible for goods to be produced on a much larger scale.Another important development was the spinning jenny, a machine that allowed for the mass production of thread. This invention, credited to James Hargreaves, revolutionized the textile industry and led to the growth of factories that were powered by water and steam.The railway system also emerged during this period, making transportation of goods and people much faster and more efficient. The first steam-powered locomotive, designed by George Stephenson, was completed in 1825, and it marked the beginning of the railway age.The Industrial Revolution had a profound impact on society as well. It led to the rise of the working class, as people moved from rural areas to urban centers in search of employment. This shift resulted in the development of new social and political structures, including labor unions and factories. It also brought about significant changes in the way people lived, with the advent ofnew forms of entertainment, such as theaters and music halls.1、What was the main purpose of the Industrial Revolution?A、To improve the quality of life for all people.B、To shift from an agrarian society to an industrial one.C、To increase the production of goods and services.D、To promote the spread of democracy and equality.2、Who is credited with the development of the steam engine?A、George StephensonB、James HargreavesC、James WattD、Richard Arkwright3、What impact did the spinning jenny have on the textile industry?A、It reduced the number of workers needed.B、It increased the efficiency of thread production.C、It decreased the quality of the thread produced.D、It made the textile industry less profitable.4、How did the railway system contribute to the Industrial Revolution?A、It decreased the cost of transportation.B、It decreased the speed of transportation.C、It increased the cost of transportation.D、It decreased the number of jobs in the transportation industry.5、What was one of the social impacts of the Industrial Revolution?A、The decline of rural communities.B、The rise of the working class.C、The decrease in the number of factories.D、The disappearance of theaters and music halls.第三题PassageThe concept of the “digital divide” has been around for a long time, but it’s only recently that we’ve begun to understand its full implications. In its simplest form, the digital divide refers to the gap between those who have ready access to computers and the internet, and those who do not. This gap can be seen along socioeconomic lines, with wealthier individuals and communities having greater access to technology than their less affluent counterparts. However, the digital divide is more complex than just a matter of income; it also encompasses issues of age, education, and even geography.In developed countries, the focus has often been on ensuring that all citizens, regardless of their economic status, have access to the internet. Governments and non-profit organizations have launched initiatives aimed at providing low-cost or free broadband services to underserved areas. Despite these efforts, disparities still exist. For example, rural areas often lag behind urban centers in terms of internet speed and availability, making it harder for residents to take advantage of online educational resources or telemedicine services.On the other hand, in developing nations, the digital divide can be even more pronounced. Here, the lack of infrastructure means that large portions of the population are completely cut off from the benefits of the digital age. Efforts to bridge this gap have included the distribution of smartphones and the establishment of public Wi-Fi hotspots, but these solutions often face challenges such as limited electricity supply and high data costs.As technology continues to advance, so too does the importance of bridging the digital divide. In an increasingly connected world, being on the wrong side of the divide can mean missing out on opportunities for education, employment, and social interaction. Moreover, as more and more essential services move online, those without access risk being left behind in a way that could have significant consequences for their quality of life.Addressing the digital divide requires a multifaceted approach, including investment in infrastructure, support for digital literacy programs, and policies that ensure affordable access to technology. Only by working together can we hope to create a truly inclusive digital future where everyone, no matter where they live or what their background, has the opportunity to participate and thrive in the 21st-century economy.1、According to the passage, which of the following is NOT a factor contributing to the digital divide?•A) Socioeconomic status•B) Age•C) Education•D) GenderAnswer: D) Gender2、What challenge do rural areas in developed countries often face in terms of the digital divide?•A) High cost of internet services•B) Lack of interest in using the internet•C) Slower internet speeds and lower availability•D) Overcrowded Wi-Fi hotspotsAnswer: C) Slower internet speeds and lower availability3、Which of the following measures is mentioned as a way to address the digital divide in developing nations?•A) Building more schools•B) Increasing the number of public libraries•C) Distributing smartphones and establishing public Wi-Fi hotspots •D) Providing free healthcare servicesAnswer: C) Distributing smartphones and establishing public Wi-Fi hotspots4、Why is bridging the digital divide becoming increasingly important as technology advances?•A) Because it ensures equal access to entertainment•B) Because it prevents people from accessing essential online services •C) Because it guarantees faster internet speeds for everyone•D) Because it helps reduce the cost of technologyAnswer: B) Because it prevents people from accessing essential online services5、What does the passage suggest is needed to effectively address the digital divide?•A) Investment in infrastructure, digital literacy programs, and policies for affordable access•B) Increased funding for traditional media•C) Restrictions on the use of smartphones•D) More emphasis on physical books and printed materialsAnswer: A) Investment in infrastructure, digital literacy programs, and policies for affordable access第四题Reading PassageAs the world becomes more and more complex, the importance of clear thinking and effective communication becomes increasingly important. One way to improve these skills is through the study of rhetoric, the art of persuasive communication. Rhetoric has been used for centuries to persuade people, whether in politics, business, or everyday life. In this article, we will explore the basics of rhetoric and how it can be applied in various contexts.Rhetoric is based on three key elements: ethos, logos, and pathos. Ethos refers to the credibility and character of the speaker or writer. Logos is the logical appeal of the argument, and pathos is the emotional appeal. A skilled rhetorician knows how to use these elements to persuade their audience.One of the most famous examples of rhetoric in action is the speech givenby Martin Luther King Jr. during the civil rights movement. King’s speech, “I Have a Dream,” was a powerful example of how ethos, logos, and pathos could be used to persuade a large audience. He established his ethos by presenting himself as a moral leader and a credible source of information. He used logos by presenting a logical argument for equality, and he used pathos by appealing to the emotions of his audience.In today’s world, effective commun ication is more important than ever. Here are some ways in which rhetoric can be applied:1.In politics, rhetoric is used to persuade voters to support certain candidates or policies.2.In business, rhetoric is used to persuade customers to buy products or services.3.In education, rhetoric is used to teach students how to communicate effectively.4.In everyday life, rhetoric is used to resolve conflicts and build relationships.Now, read the following passage and answer the questions that follow.Passage:The use of rhetoric in advertising has become increasingly sophisticated over the years. Advertisers understand that people are not just interested in the features of a product; they are also interested in how the product makes them feel. This is where pathos comes into play. Advertisers use emotional appeals to create a connection with the audience, making them feel a sense ofbelonging or aspiration. For example, a car commercial might show a family enjoying a happy, carefree life together, suggesting that the car will bring the same happiness to the viewers.1、What are the three key elements of rhetoric?2、How did Martin Luther King Jr. use ethos, logos, and pathos in his “I Have a Dream” speech?3、In what ways can rhetoric be applied in everyday life?4、What is the role of pathos in advertising?5、Give an example of how emotional appeals are used in a car commercial.Answers:1、The three key elements of rhetoric are ethos, logos, and pathos.2、Martin Luther King Jr. used ethos by presenting himself as a moral leader, logos by presenting a logical argument for equality, and pathos by appealing to the emotions of his audience.3、Rhetoric can be applied in everyday life to resolve conflicts and build relationships.4、The role of pathos in advertising is to create a connection with the audience by appealing to their emotions, making them feel a sense of belonging or aspiration.5、An example of how emotional appeals are used in a car commercial is a scene showing a family enjoying a happy, carefree life together, suggesting that the car will bring the same happiness to the viewers.三、阅读理解新题型(10分)Part III: New Type Reading ComprehensionDirections: Read the following passage carefully.

带动效应英语Here is an essay on the topic of "Spillover Effect" in English, with the content exceeding 1000 words as per your instructions. The essay does not include a title and has no extra punctuation marks in the main body.The modern global economy is a complex and interconnected system, where the actions and decisions of one entity can have far-reaching consequences on others. This phenomenon, known as the "spillover effect," is a crucial concept in understanding the dynamics of the world's economic landscape. The spillover effect refers to the indirect impact that one event, decision, or change can have on other related entities, sectors, or regions, even if they are not directly involved.One of the most prominent examples of the spillover effect can be seen in the financial markets. When a major financial institution experiences a crisis or instability, the ripple effects can be felt across the entire financial system. The collapse of Lehman Brothers in 2008, for instance, triggered a global financial crisis that had devastating consequences for economies around the world. The failure of this one investment bank led to a domino effect, as other financialinstitutions, businesses, and consumers were impacted by the resulting credit crunch, stock market volatility, and economic downturn.The spillover effect is not limited to the financial sector; it can also be observed in various other industries and domains. In the realm of international trade, for example, the imposition of tariffs or trade barriers by one country can have a significant impact on the economies of its trading partners. When a country raises import duties on certain goods, the increased costs can lead to higher prices for consumers in that country, as well as reduced demand for the affected products. This, in turn, can affect the suppliers and producers in the exporting countries, leading to decreased sales, job losses, and economic slowdown.Similarly, the development of new technologies or innovations can have a profound spillover effect on related industries and sectors. The advent of the internet, for instance, has transformed the way we communicate, work, and access information, leading to the disruption of traditional business models and the emergence of entirely new industries. The rise of e-commerce, for example, has had a significant impact on the retail sector, forcing traditional brick-and-mortar stores to adapt their strategies and operations to compete with online platforms.The spillover effect can also be observed in the realm of social and environmental issues. The outbreak of a pandemic, such as the COVID-19 crisis, can have far-reaching consequences beyond the immediate health impact. The lockdowns and social distancing measures implemented to control the spread of the virus have led to widespread economic disruption, job losses, and mental health challenges. These ripple effects have been felt across various sectors, from hospitality and transportation to education and healthcare.Moreover, the environmental impact of human activities can also have spillover effects. The deforestation of the Amazon rainforest, for instance, not only affects the local ecosystem but also has global implications for climate change, biodiversity, and the well-being of indigenous communities. The loss of these vital natural resources can then have cascading effects on related industries, such as agriculture, tourism, and the pharmaceutical industry, which rely on the preservation of these ecosystems.The recognition of the spillover effect is crucial for policymakers, business leaders, and individuals alike. Understanding how actions and decisions in one area can have unintended consequences in other domains is essential for developing effective strategies and policies that address complex, interconnected challenges. By anticipating and mitigating potential spillover effects, stakeholders can make more informed decisions and implement more holisticsolutions that consider the broader implications of their actions.In conclusion, the spillover effect is a fundamental concept that highlights the interconnectedness of the modern world. From financial markets to technological innovations, social issues to environmental concerns, the ripple effects of one event or decision can have far-reaching consequences that extend beyond the immediate scope of the initial action. By recognizing and understanding the dynamics of the spillover effect, we can better navigate the complex and ever-evolving global landscape, fostering more resilient and sustainable systems for the benefit of all.。

This period began with the British industrial revolution around the 1860s and completed the establishment of industrial society in European and American countries around the 1870s, including the whole period of capitalism, which lasted about 100 years. The formation of the world economy in this period was based on the large machinery industry, mainly marked by the establishment of the international division of labor system and the development of the world market.(3) Final formation period. From the 1870s to the beginning of the20th century, with the deepening of international division of labor and the expansion of the scope of the world market, especially the great progress of production and capital internationalization characterized by capital export, and the completion of the division of world territory, the real world economy finally took shape.Chapter II1. How to understand the process and connotation of economic globalization?Process: economic globalization is a process and a state of the development of the world economy to a higher level. Economic globalization is driven by the contemporary scientific and technological revolution, the market economy and the great development of multinational corporations. The great development of international trade, international finance, international investment, international transportationand communication, as well as the migration of international population, has led to the large-scale flow of production factors all over the world, and expanded the internal division of labor of enterprise production into a global division of labor, It is a state and process of unprecedented acceleration and deepening of interdependence and integration of countries by optimizing the combination and allocation of production factors on a global scale.Connotation: (1) economic globalization is the unity of economic category and historical category(2) Economic globalization is a concept related to time and space(3) The essence of economic globalization is the globalization of capital and its carrier expansion(4) Economic globalization is dominated by developed countries, and there are many asymmetries in its structure.2. Reasons and manifestations of the accelerated process of post-war economic globalization.Reasons: (1) the great development of scientific and technological revolution(2) The market economy system expands to the whole world(3) The development of trade, investment and financial liberalization in western countries(4) The great development of multinational corporations.Performance: (1) trade liberalization and global networking: with trade liberalization and information networking, the scope and scale of world trade have expanded sharply(2) Globalization of financial, monetary and investment markets: globalization of financial markets, currency circulation and investment activities(3) Globalization of human resource flow: the number and scope of worldwide immigrants have expanded, the transnational training and flowof talents have increased significantly, and the trend of "hidden transnational flow" of talents has increased.(4) The formation of global industrial chain and the globalization of international production system: the development of global industrialization and the formation of industrial chain followed by echelons around the world; Formation of global production system(5) The international economic coordination mechanism has gradually taken shape.3. How to understand the opportunities and challenges brought by economic globalization to developing countries?Opportunities: developing countries and regions adapt to the general trend of economic globalization, actively take advantage of the opportunities of deepening international division of labor and worldwide industrial structure adjustment, adopt opening-up strategies and policies in line with their national conditions, introduce foreign capital, technology and management experience, and improve their industrial structure and product quality, We should improve the competitiveness of our national enterprises as soon as possible, vigorously develop foreign trade, fully and reasonably allocate domestic resources and realize the rapid development of our economy. Economic globalization can also promote political reform in developing countries and accelerate the process of democratization.Challenges: (1) developing countries are at a disadvantage in the current process of economic globalization. With the rapid development of Global trade and global production system, the national economy of developing countries is facing great pressure and impact, and its dependence on developed countries is also increasing.(2) Economic globalization has led to and exacerbated the further imbalance of world economic development, and developing countries lag behind developed countries, especially those at the bottom.(3) the unbalanced development of China's developing countries is also increasing, which poses a potential threat to investment, stimulatesthe development of the bubble economy, and lays hidden danger for the financial crisis.(4) The biggest problem or threat brought by economic globalization to developing countries is that their national sovereignty has been impacted and weakened, and their national economic security has been challenged.(5) It has brought enormous pressure on the reform of developing countries. Economic globalization has strengthened the economic transmission and synchronization. How to accept the positive transmission and curb the negative transmission has become a major problem urgently needed to be solved by developing countries.5. What impact has economic globalization had on national sovereignty and the world pattern?Economic globalization has impacted national sovereignty, and mutual coordination has become the main theme of the times. Originally a unique right of a country, it has increasingly become a common power of the international community. National economic activities are increasingly operating in accordance with international treaties, agreements, norms and practices; The improvement of the status of multinational corporations in the economic life of various countries weakens the intervention of the state in industrial policy.Economic globalization is one of the decisive factors in the development, evolution and final formation of the world pattern after the cold war. As economic globalization has greatly strengthened the role of the law of unbalanced development, the status of some countries in the world pattern has declined, while the influence and role of others in the world pattern have increased. In this way, the world pattern, as the global core structure, will undergo a major adjustment in the balance of power. Economic globalization has promoted world multipolarization, which has enhanced human harmony.In economic globalization, with the accelerated transfer and movement of production factors in the world, the problem of global public hazards has become increasingly prominent. Their harm involves not only developing countries, but also developed countries, and even the whole world. Therefore, the process of economic globalization will inevitably bring many international political and economic frictions.Chapter III1. What are the basic characteristics of the post-war scientific and technological revolution? What impact does it have on the development of national economy and world economy?Basic features of the post-war scientific and technological revolution:1) Comprehensive and worldwide. 2) The scientific revolution and the technological revolution have developed simultaneously and formed the integration of science, technology and production.3) The machine system, labor style and lifestyle have been innovated. 4) the development of science and technology and its application in production have been strongly supported by the government.Impact: the post-war scientific and technological revolution has brought about great development of social productive forces and great changes in the structure of productive forces:(1) The great development of productive forces. It has greatly improved labor productivity, expanded capital accumulation and expanded the commodity market.(2) The transformation of the substantive elements of productivity: the workers are becoming more and more intelligent, the labor tools are becoming more and more automatic, and the labor objects are becoming more and more artificial.(3) Strengthening of non substantive elements of productivity: Science and technology has become the first productivity, and education has become an important reinforcing element in modern productivity.(4) Changes in industrial structure. The basic feature of its change is the shift of the focus of industrial structure. The proportion of material production sectors such as industry and agriculture in the national economy decreased, while the proportion of non-material production sectors such as service industry increased.The third scientific and technological revolution raised the level of world productivity and accelerated the recovery and development of the world economy after the war; Promoted the development of international trade; It has promoted the development of multinational corporations and international economic integration, widened the gap between the rich and the poor all over the world, and promoted the changes of social production relations all over the world(5) The third scientific and technological revolution not only brought about the modernization of things, caused changes in the way of labor and life, and gradually modernized people's ideas, ways of thinking, ways of behavior and ways of life.。

Strategies for Developing Policies and Requirements for Secure Electronic Commerce SystemsSubmitted to: 1st Workshop on Security and Privacy in E-Commerce at CCS2000Annie I. Antón Julia B. EarpDepartment of Computer Science Department of Business Management College of Engineering College of ManagementNorth Carolina State University North Carolina State University Engineering Graduate Research Center 408Campus Box 7229Raleigh, NC 27695-7534Raleigh, NC 27695-7229+1.919.515.5764+1.919.513.1707aianton@ Julia_Earp@AbstractWhile the Internet is dramatically changing the way business is conducted, security and privacy issues are of deeper concern than ever before. A primary fault in evolutionary electronic commerce systems is the failure to adequately address security and privacy issues; therefore, security and privacy policies are either developed as an afterthought to the system or not at all. One reason for this failure is the difficulty in applying traditional software requirements engineering techniques to systems in which policy is continually changing due to the need to respond to the rapid introduction of new technologies which compromise those policies. Security and privacy should be major concerns from the onset, but practitioners need new systematic mechanisms for determining and assessing security and privacy. To provide this support, we employ scenario management and goal-driven analysis strategies to facilitate the design and evolution of electronic commerce systems. Risk and impact assessment is critical for ensuring that system requirements are aligned with an enterprise’s security policy and privacy policy. Consequently, we tailor our goal-based approach by including a compliance activity to ensure that all policies are reflected in the actual system requirements. Our integrated strategy thus focuses on the initial specification of security policy and privacy policy and their operationalization into system requirements. The ultimate goal of our work is to demonstrate viable solutions for supporting the early stages of the software lifecycle, specifically addressing the need for novel approaches to ensure security and privacy requirements coverage.1.IntroductionOrganizations are hastily investing time and monetary resources in electronic commerce systems to support traditional business activities. By enhancing customer responsiveness and speeding up product delivery time, electronic commerce greatly reduces administrative costs and improves efficiency. However, protecting a digital marketplace is more complex than protecting the physical one. Information is dispersed so easily through electronic transactions that it is often difficult to differentiate between illegal actions and legitimate market research or flexible actions to accommodate electronic commerce partners [ATW98, Bor96]. Concerns over the security and integrity of electronic commerce transactions initially stifled the adoption of e-commerce [Ale98, Ger97]; however, this is no longer a primary concern. Although Internet security is sometimes considered poor, it is not impeding the rapid growth of electronic commerce. Some businesses, as well as individuals, are willing to accept the risks; however, Internet users as a whole are concerned about their personal privacy and the security of their online transactions [CRA99].When compared to information systems of the past, electronic commerce systems are more vulnerable to accidental distortion, distribution and deletion of critical transaction data [EPB00]. Transactions conveyed on paper are somewhat secure because of the inherent difficulty of accessing and searching their content, thus hindering the usefulness to abusers who might breach confidentiality. When transactions are stored and exchanged using electronic commerce systems, however, information such as credit card numbers, electronic receipts and purchase orders become more accessible. This ease of access creates the potential for wider and more systematic breaches of information privacy. Information assets are core components of electronic commerce systems; therefore, protection of these assets is not an option but a necessity if commerce is to flourish.Successful privacy and data protection is a result of appropriate security measures. Moreover, protecting an electronic commerce system cannot be accomplished with a single security method. It is important to identify appropriate combinations of proven policies, procedures and devices to ensure the success of a secure networked environment.Although the Internet is a promising means of facilitating the growth of electronic commerce, there remain many challenges that we seek to address. Technology problems of slow modem access and congestion are common, but are receiving widespread attention via new technologies such as ADSL (Asymmetrical Digital Subscriber Line) and intelligent routing. In contrast, software problems related to privacy and security pose a much greater challenge for researchers and software practitioners. To keep pace with the predicted explosive growth of electronic commerce, there is a great need for proven methods aimed at developing secure systems. This paper outlines an innovative approach for designing electronic commerce systems with a direct emphasis on addressing security and privacy needs from the early stages of conceptual design.Our integrated approach applies goal and scenario-driven requirements engineering methods for secure electronic commerce systems resulting in the specification of: privacy policies, security policies and the corresponding system requirements for these proposed or envisioned systems. Section 2 provides an overview of the state of the research and practice in security and privacy policy. Section 3 provides relevant background in requirements engineering. Our strategy (an instantiated GBRAM model for policy development) is presented in Section 4, followed by a summary and discussion of future work in Section 5. 2.Security and PrivacyThis section provides an overview of the relevant work in security, security policy, privacy and privacy policy.SecurityReducing threats to sensitive data is the focus of several studies addressing methods to provide better security for data privacy [BB95, BS96, MW98]. However, the balance between security and information accessibility necessary for normal business operation must also be considered [EP00]. Most organizations are aware of the problem of unauthorized access to personal data, but few have established an effective security program for their systems [SKR99]. Electronic commerce systems must be protected from both internal and external threats and their protection deserves special consideration during the early design stages. Despite the increased awareness of heightened security needs, most organizations are facing a shortage of security skills [Mak99], highlighting the need for a heavier focus on systems with security requirements at the conceptual design phase. Similarly, Shimeall et.al. [SM99] highlight the increasing need for applications to be written with more concern for security to thwart the potential for vulnerabilities often exploited by attackers.Although many organizations employ ethical codes for employees to follow; these policies provide no real guarantee against unauthorized access. The ability to determine where the business need is for security and what security features are appropriate, given the organizational environment, is vital when developing electronic commerce applications for today’s businesses. The challenge lies in ensuring that thepolicies are reflected in the system requirements from which these electronic commerce applications will be designed.Security PolicyThe primary step in securing an electronic commerce system is developing and implementing a dynamic document called a security policy [Dea00], which identifies system aspects such as security goals and risks. It is important to establish who the authorized users might be, how they will access the system and data, how unauthorized users will be denied access, and how data will be protected within the organization as well as outside the organization.Thoroughly planned security policies help minimize break-ins by communicating with and managing the users in an organization. Unfortunately, security policies are often treated as an after-thought [Trc00]. The strategies presented in this paper address this occurrence in electronic commerce systems by integrating policy creation and security considerations with requirements specification activities.Although several methods for developing specific types of security policies have been proposed [AB95, And96, ISO98, Lic97, NI94, OA95, Oln94, PFI99, SW98, Trc00,]; few consider the dynamic nature and innovativeness of creating policies specific to electronic commerce applications [Oli97]. A security policy must address an organization’s specific risks. To understand risks, an appropriate player should perform a security audit that identifies vulnerabilities and rates both the severity of each threat and its likelihood of occurring. Today’s digital economy offers more areas for risk to be introduced through the involvement of various parties, such as suppliers, distributors, customers, and partners. Researchers [Lic97, SM99] highlight the immediate need to address key research issues in current security development methods. Specific challenges to policy research raised by Lichtenstein [Lic97] include the need to address the ill-defined content and structuring of content in policy development.The PFIRES (Policy Framework for Interpreting Risk in eCommerce Security), developed at the Purdue University CERIAS (Center for Education and Research in Information Assurance and Security), provides a framework for managing information security policy for electronic commerce applications [PFI99]. The framework addresses the need to unify security policies in a manner consistent with organizational electronic commerce objectives. Security policies must be continually reviewed and updated to respond to changes in technology as well as the business environment; the PFIRES lifecycle model supports this iterative process by managing risks as an organization adopts new technologies which may compromise its existing security and/or privacy policies. While the PFIRES plan phase does include a requirements definition step, it does not currently offer systematic prescriptive guidance to the analysts who are actually responsible for translating policy recommendations into requirements.Trcek [Trc00] has developed an approach to security policy management that provides an integrated solution from various fields (e.g. cryptography and human management). Trcek observes that development of information systems is typically top-down, whereas security methods are incorporated bottom-up; he thus advocates addressing policy development during analysis and design. His approach begins with an analysis of the business processes and identification of individual entities to be classified into security domains. Data flow diagrams are employed to model the process in a static perspective so that information flows may then be evaluated and enforced by flow controls. Trcek identifies some important aspects of policy management, but provides no guidance for the process of defining policy requirements. PrivacyPrivacy is a concept that is not easily defined [Tav99], but it is often thought of as a moral or legal right [Cla99]. Clarke describes privacy as the “interest individuals have in sustaining personal space free from interference by other people and organizations” [Cla99]. Privacy thus affects electronic commerce consumers as well as consumers, or stakeholders, in other domains. Consider, for example, the role of a patient's information privacy in the health care industry as explored in a recent study [EP00]. The study measured privacy perceptions of employees having daily exposure to information processing activities. The findings concluded that employees are torn between their respect for personal privacy and the need,whether imposed by management or through individual thinking, to collect personal information. Similarly, there exists a need to explore these same issues within the context of developing electronic commerce applications.Self-regulation has been proposed as means to address concerns about consumer privacy [McG99]. The FTC (Federal Trade Commission) recently issued a report to the United States Congress encouraging industry to address consumer concerns about privacy through self-regulation [FTC98]. This report was presented despite the fact that self-regulation had previously been encouraged and most online businesses still had not adopted the fundamental fair information practices that address consumer privacy. In response, [Ben99] suggests privacy seals (e.g. TRUSTe, BBBonline and WebTrust) to prevent the introduction of legislation that will be introduced if companies can not effectively achieve self-regulation. Alternatively, the P3P project (Platform for Privacy Practices Project) offers a means to enable Internet users to exercise preferences over Web site privacy practices [RC97].Information privacy is impacted by organizational functions such as electronic commerce, database management, security techniques, telecommunications, collaborative systems and systems implementation [EP99]. Developers of electronic commerce systems need to be aware of this connection and realize the need for early privacy planning. Clearly, it is necessary to consider these factors throughout the requirements determination and software design of electronic commerce systems.Privacy PolicyA privacy policy is defined as a comprehensive description of a Web site’s practices which is located in one place on the site and may be easily accessed [FTC98]. Every organization involved in electronic commerce transactions has a responsibility to adopt and implement a policy for protecting the privacy of individually identifiable information. Organizations also need to consider other organizations with which they interact and take steps that foster the adoption and implementation of effective online privacy policies by those organizations as well. Although, organizations engaged in electronic transactions should disclose a privacy policy that is based on fair information practices, the Georgetown Internet Privacy Policy Survey [GIP99] found that Internet privacy disclosures did not always reflect fair information practices. This highlights the need for electronic commerce professionals to gain experience in developing proper privacy policies and for practitioners to have access to prescriptive guidance for specifying the corresponding system requirements. The strategies presented in Section 4 include heuristics and techniques to aid practitioners as they develop both security and privacy policies which may be operationalized into system requirements.3.The Role of Requirements Engineering in the Design of eCommerce SystemsRequirements engineering is the principled application of proven methods and tools to describe the behavior and constraints of a proposed system. As such, it arguably influences the outcome of a software project more than any other sub-discipline within software engineering [FB91] as well as the outcome of other analysis activities such as policy formation. Lichtenstein’s framework for developing Internet security policy promotes a four phase strategy to engineer information security: requirements definition, design, integration, and certification or accreditation [Lic97]. Unfortunately, the framework offers no specific methods to address the requirements definition phase. Similarly, as previously mentioned, the PFIRES framework, does not provide adequate support for translating policy recommendations into system requirements [PFI99]. Although researchers in the requirements engineering community are beginning to focus on electronic commerce applications [AP98, ADS00, Rob97] there remains a need to apply proven requirements analysis methods (a routine activity in software engineering) and demonstrate how to best apply these methods within the context of establishing policy. Goal and scenario analysis have been successfully applied within the context of evolving electronic commerce systems [AP98] as we now discuss.Goals and ScenariosGoals are the objectives and targets of achievement for a system. In requirements engineering, goal-driven approaches focus on why systems are constructed, expressing the rationale and justification for the proposed system. Since goals are evolutionary, they provide a common language for analysts and stakeholders. Focusing on goals, instead of specific requirements, allows analysts to communicate with stakeholders using a language based on concepts with which they are both comfortable and familiar. Furthermore, since goals are typically more stable than requirements [Ant97], they are a beneficial source for requirements derivation. Goals are operationalized and refined into requirements and point to new, previously unconsidered scenarios. Scenarios are descriptions of concrete system behaviors. They may summarize the behavior traces of an existing system. Scenarios also help in the discovery of goals [AMP94, AP98, JBC98, Pot99, RSB98]. Although the merits and benefits of scenario-based and goal-based analysis in requirements engineering are well understood, researchers are now faced with the question of how to use scenarios and goals in a complimentary fashion for evolving systems in which risk and impact assessment as well as compliance become more paramount.Goal-Based Requirements EngineeringThe Goal-Based Requirements Analysis Method (GBRAM) [Ant96, Ant97, AP98, ADS00] is a straightforward methodical approach to identifying system and enterprise goals and requirements. It is useful for identifying and refining the goals that software systems must achieve, managing trade-offs among the goals, and converting them into operational requirements. The method suggests goal identification and refinement strategies and techniques through the inclusion of a set of heuristics, guidelines and recurring question types. Four sets of heuristics are included: identification heuristics, classification heuristics, refinement heuristics, and elaboration heuristics. The heuristics are useful for identifying and analyzing specified goals and scenarios as well as for refining these goals and scenarios. The GBRAM heuristics and supporting inquiry include references to appropriate construction of scenarios and the process by which they should be discussed and analyzed. We have successfully applied this method to the analysis of systems for various organizations [AMP94, Ant96, Ant97, AP98, ADS00]. The latter two of these systems were electronic commerce applications [AP98, ADS00].Securing sensitive data is essential from the initial design phase of a system and the cost of security controls must be appropriate for the risk environment of the individual system. A risk analysis is needed to determine the stringency of the policy. This, in turn, will affect the cost of the security controls employed to meet the requirements of the security policy. Although methods and guidelines exist for managing and developing security policies [AB95, And96, ISO98, Lic97, NI94, OA95, Oln94, PFI99, SW98, Trc00], our goal-driven approach provides structured prescriptive guidance, in the form of a set of heuristics [Ant97, AP98, Dem00], for identifying new, previously overlooked goals based on the results of risk assessment activities. These goals are, in turn, operationalized into policies and system requirements. 4.Specification Strategies for Security Policy and RequirementsThe primary goals in developing a security policy are to define organizational expectations for proper system use and define procedures to prevent, and respond to, security events. Similar to other organizational policies, the security policy must maintain and complement the organization’s business objectives. The creation of a security policy for networked systems is inherently an ongoing and iterative process due to the dynamic nature of electronic commerce systems. When new technologies are adopted, an organization’s security policy and privacy policy must be revisited and oftentimes revised to respond to the policy conflicts introduced by these new technologies. Thus, there is a need for an evolutionary approach for security policy development. Our proposed strategies involve the application of proven goal-and scenario-based requirements analysis techniques in the design and implementation of electronic commerce applications. The strategies and associated heuristics are designed to ensure that system requirements are in compliance with enterprise security and privacy policy.The steps involved in security policy development for networked systems in general, include the following activities [Sun99]:•identifying assets centered around software, hardware, people and documentation;•evaluating and prioritizing those assets;•identifying risks and vulnerabilities, including the probabilities of each;•defining a policy of acceptable use based on work ethic and culture;•identifying necessary safeguards, including physical security, audit/logging and incident response;•creating the plan for a phased approach to introducing the policy; and•communicating policy to users within the organization, as well as appropriate external individuals such as partners.When applied specifically to electronic commerce systems, the risk identification phase is more significant and critical because such a highly interconnected environment inherently sustains added vulnerabilities. A risk occurs when a threat exploits a vulnerability to cause harm to the system. Security policies provide a baseline for implementing security controls to lessen risk introduced by vulnerabilities. The number of vulnerabilities in today’s electronic commerce systems is massive when compared to the earlier environments of mainframes and dumb terminals. For this reason, system developers of the present require meticulous methods for organizing risk profiles into electronic commerce systems and system policy.The strategies described below build on the PFIRES approach for assessing risk in eCommerce systems [PFI99]. The PFIRES framework employs a lifecycle model that consists of the following phases: Assessment, Planning, Delivery and Operation. While each phase of the model is marked by specific exit criteria that must be met before proceeding to the next phase, it does include feedback loops due to the iterative nature of policy development in eCommerce systems. Risk assessment is built into the lifecycle and policy changes are classified along a “change continuum”; tactical changes involve short-term goal achievement whereas strategic changes involve long-term, broad-based initiatives. Our strategy for policy formation focuses on goals that reside along this change continuum.In requirements engineering, “strategic goals” are those that reflect high-level enterprise goals. Since these goals are typically more stable than requirements [Ant97], they are a beneficial source for requirements derivation. Similarly, one can safely assume that strategic goals are more stable, due to their long-term nature, than tactical goals. Both strategic and tactical goals are important, but as observed in previous studies, scenario analysis aids in ensuring that tactical (low-level) goals support an organization’s strategic (high-level) goals [AMP94]. During goal analysis, analysts first explore any available information sources such as existing security and privacy policies, requirements specifications and design documentation to identify both strategic and tactical goals. These goals are documented and annotated with auxiliary information including the stakeholders and responsible agents. Goals are then organized according to goal type and arranged, according to their dependency relations, in a goal hierarchy. Detailed techniques and heuristics for each of these operations are described in [Ant97]. Once the goals are identified, they are elaborated. Goal elaboration entails analyzing each goal for the purpose of documenting goal obstacles, scenarios, constraints, preconditions, postconditions, questions and rationale. Goal refinement consists of removing synonymous and redundant goals, resolving any inconsistencies that exist within the goal set [Dem00], and operationalizing the goals into a requirements specification.Figure 1 portrays the activities involved when instantiating the GBRAM for policy development. The rectangles represent information sources and/or artifacts whereas the ovals represent specific activities in which an analyst engages during the goal analysis process. The figure includes the traditional GBRAM activities (identify, elaborate, refine and operationalize goals) [Ant96, Ant97, AP98], but has been tailored for defining privacy policy and security policy. As previously mentioned, a critical step in policy formation is iterative risk assessment [PFI99, Sun99]. Risk assessment is thus introduced in this tailored version of the GBRAM; each goal is assessed for risks and potential impacts. As shown in Figure 1, risk identification may require one of two actions: goal refinement (e.g. by adding a constraint to mitigate the risk) or the addition of a new goal or sub-goal to respond to the risk. This is extremely important since system requirements in response to the adoption of new technologies, such as auctions [PFI99], mayintroduce a conflict with respect to the resulting policy. Heuristics, available in [Dem00], are applied to prevent such conflicts from being overlooked during the analysis process.Figure 1: The GBRAM instantiated for Policy FormulationIn the GBRAM, goals are categorized in one of five goal classes: user, system, communication, knowledge and quality goals [Dem00]. User goals are associated with the actions performed by users while interacting with a given system. System goals involve processing actions or ongoing provision of services by the system. Communication goals describe the organization and presentation of information by the system as well as general system notification and messaging [AP98]. All communication goals are functional since they involve goal achievement. Knowledge goals are associated with information that should be known by the system or by the users. Security goals describe those goals involved in limiting access to authorized users [AP98]. Finally, quality goals describe the system, its data, or its processes in terms of standards or constraints. These categories are not mutually exclusive; that is, a particular goal can be, and often is, classified according to more than of these goal classes.Our analyses of electronic commerce systems [AP98, ADS00] demonstrate that the availability of goal classes can be very beneficial when developing the requirements for systems since the goal classes can help ensure that all expected behaviors have been considered for the given system. When goals are operationalized, we expect a correspondence between these goal classes and specific parts of the security policy as summarized in Table 1.GBRAM Goal Classes [Dem00]Common Security Policies [PFI99] User Goals User behavior policySystem Goals Extranet/Internet policyAccess to data policyAdministration policyCommunication Goals Administration policySecurity Goals Password policyRemote access policyExtranet/Internet policyIncident response policySecurity monitoring and audit policyPrivacy policyKnowledge Goals User identification policyAccess to data policyIncident response policyAwareness procedure pollicyPrivacy policyQuality Goals Security monitoring and audit policyTable 1: Security Policies and Corresponding Goal Classes。
