Deployment of Firewall and Intrusion Detection and Prevention Systems

The combination of hardware and software that selectively allows communication between a computer and a network is known as a firewall (Fithen, Allen Stoner, 1999). It inspects the traffic during a network communication and blocks or permits passage depending on a given set of rules. The term Intrusion Detection and Prevention Systems (IDPS) refers to both Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS).Advertising We will write a custom essay sample on Deployment of Firewall and Intrusion Detection and Prevention Systems specifically for you for only $16.05 $11/page Learn More Intrusion Detection is a process of monitoring the activities occurring in a computer network and determining if they are in violation of standard security policies. The software that automatically carries out the process is known as IDS. IPS is able to carry out the intrusion detection process and can try to stop the intrusion/violation (Scarfone Mell, 2007). Various firewall arrangements can be used for multitier applications accessible from the World Wide Web and from an internal network. Multitier web applications of moderate complexity are segmented into three tiers. The first tier is made up of the presentation components that are accessible directly by end users. The second tier is composed of middleware components that execute the end users’ requests. End users cannot access them directly. The third tier consists of data components. They are the most sensitive and are hosted by databases or directory servers. Firewall deployment is based on three strategies. The first strategy is the single firewall strategy, which is used to protect all the three tiers from the internet and internal network. All the communication going in and out of the three tiers goes through a single firewall. The firewall offers equal protection to all the servers but can subdivide the network into different subnets and offer different protectio n level to the subnets. Firewall in series strategy is whereby several firewalls are deployed to eliminate reliance on a single firewall. The firewalls are deployed one behind another and therefore the more sensitive tiers are behind more firewalls. For example, the data components tier would be behind both the firewall protecting it and the one protecting the middleware components and presentation components. The last strategy is the hybrid strategy, which uses only two firewalls. Either presentation servers and middleware servers or data servers and middleware servers are grouped together. Although two tiers are grouped together, they remain under dedicated subnets. In the first grouping, presentation servers and middleware servers are behind one firewall while data servers are behind two firewalls. All firewall arrangements are on the internal side of a router.Advertising Looking for essay on it? Let's see if we can help you!

When connected out-of-band, it uses a hub, a spanning port or a network tap. Deploying both ISP and IDS is more beneficial and to do this, a router must be introduced. The IPS is connected on the external side of the router and the IDS is connected in internal side of the router either inline or out-of-band (Pappas, 2008). The IDS placed on the inside section of the edge router allows analyzing of communication within the internal network. The use of firewalls and IDPS is beneficial. Firewalls block network traffic that may be violating the security policy of an organization. Such traffic may include viruses, spam, email bombs and unwanted material. IDPS detect and stop malicious incidents that would compromise security of a given computer system. They can detect when an attacker has compromised the system and stop suspicious file transfers. By identifying reconnaissance activities, they can prevent e minent future attacks. Reference List Fithen, W.L., Allen, J.H. Stoner, E., (2008). Deploying firewalls. Software Engineering Institute.

Economies of Scope and the Modern Technology

Economies of Scope and the Modern Technology Introduction: Economies of Scope as an Object of the Research The role of economics of scope has increased considerably since recently, which presupposes that the changes occurred in the given sphere should be considered closer and analyzed to understand the methods that enhanced the growing development of the given economics.Advertising We will write a custom report sample on Economies of Scope and the Modern Technology specifically for you for only $16.05 $11/page Learn More Therefore, the elements that economies of scope are comprised of, as well as the effects that the recent surge of technological development, as well as the numerous technological innovations, had on the given entrepreneurship is of major importance. It is necessary to mark that the phenomenon of economics of scope must not be confused with the one of the economies of scale. Since the two phenomena concern the same sphere yet are composed of different elements, it is required to draw th e line between the two. According to the description provided by Parkin, Powell and Matthew (2007), â€Å"a firm experiences economics of scale when an increase in its output of a good or service brings a decrease in the average total cost of producing it† (227). However, the authors mark that both the economics of scale and of scope â€Å"can lead to natural monopoly† (Parkin, Powell and Matthew 2007, p.227). It is worth marking that Parkin, Powell and Matthew (2007) emphasize the importance of technological innovations for the economies of scale: â€Å"In a period of rapid and fars In the given paper, such economics of scope are considered as the Xerox Company, the U.S. Telecommunications Industry, as well as the local exchange company and local operating company are considered. With the help of the analysis of their peculiarities and development, one can come to the conclusion concerning the companies’ strategic operations, their tactics and the way the give n economies have utilized the new technologies that were at their disposal. However, it is important to mark the opportunities that each company had before the implementation of the technological changes. It is worth marking that Xerox Co. is one of the businesses that is developing rapidly and, hence, requires expanding, creating affiliates and managing them successfully. Speaking of the other sphere of economies of scope that are considered in the given paper, the one concerning the telecommunication issues, it is necessary to explain that in the given sphere, â€Å"the existence of economies of scope remains an important but ambiguous issue† (Banker et al 1998, p.254). Therefore, differences in the development of the given companies predetermine the complexity of the analysis, making the latter considerably objective, though. Tracking the Progress: The Role of the Technologies It is worth mentioning that in the companies under the considerations, the technological, innovat ions introduced have played quite different roles despite such common feature as the fact that the companies in question both belong to the economies of scope and, hence, are supposed to develop according to a certain pattern.Advertising We will write a custom report sample on Economies of Scope and the Modern Technology specifically for you for only $16.05 $11/page Learn More Nevertheless, it is worth mentioning that in the sphere of the U.S. telecommunications, the economies of scope are closely interconnected with the rapid progress of the U.S. telecommunications, yet there is no tangible connection between the two; as the authors claim, the given elements impact the same sphere of financial issues, yet the connection between the two is quite vague: â€Å"Moreover,†¦ the evidence cannot adequately disentangle the effects of two factors that both reduce unit costs – economies of scale and technological advance† (p.256). In contrast to t he given phenomenon, the economy of scale that Xerox Co. represents offers rather substantial reasons for implementing the strategy that economy of scale presupposes. Grounding their ideas and suggestions on the current state of the company’s affairs, the managers come to the conclusion that the technological innovations that have been implemented so far require the change of the company course of n economy of scope, marking that the old model of operating the company does not suit the innovations in the sphere of technologies: â€Å"In other cases, though, such a business model will not fit the circumstances of the technological or market opportunity† (p.2). Concerning the Course of Actions: Strategic Implications Analyzing the specific strategies that the given economies of scope utilize to achieve the maximum efficiency and decrease the costs that they suffer, one must mark that each of the given entrepreneurships has chosen it sown pace and model of development, wh ich calls for another comparison on the efficiency of the given approaches. Nevertheless, it is necessary to comment on the strategic implications themselves first. Observing the specifics of the strategic implications that the economies of scale presuppose for the given companies, one can come to the conclusion that with the help of the strategies chosen by the companies, a rapid increase in the revenues is about to occur.Advertising Looking for report on business economics?

The Related Concepts: Discussing the Commercial Integrity Obviously, the issue of economies of scope and the technological innovations tat trigger the latter cannot be considered alone, since there is a number of factors dependent on the aforementioned economies, and, vice versa, the given corporations depend considerably on the issues intertwined with the problem of providing innovations in the sphere of economic and business. Crating the specific environment for the developme nt of the given ventures, one can claim with certainty that the success of the entrepreneurship follows immediately, which means that the elements of the environment that the companies in question operate in must be considered thoroughly. Introducing the peculiar details, one will be able to see the related concepts that contribute to building a successful business. Among the concepts of the kind, the commercial integrity takes the first place. As Chesbrough and Rosembloom (2002) say, â€Å"some scholars conclude that firms may indeed develop the ability to manage new technological opportunities effectively if they invest in integrative capabilities†¦, ambidextrous internal processes†¦, or complementary assets† (p.5), hence, emphasizing the necessity to create the commercial integrity of the economies in question. Hence, the integrity of the U.S. telecommunication companies cannot be doubted at the moment, which obviously leads to the prosperity of the latter, where as Xerox Corporation seems to have problems concerning the integrity of the company (Banker et al 1998), which triggers certain concerns for the company future. Hence, the integrity of the economies of scope is essential for the well-being of the latter. Conclusions: Economies of Scope: The Importance of Technologies Development Judging from the research conducted and the data obtained, one can come to the conclusion that in most cases, the transition to the development of economies of scope is predetermined by the necessity to implement certain technological changes and offer various innovations into the company. Therefore, the transition to the strategies of economies of scope can be considered a natural course of events for major companies like Xerox or the U.S. Telecommunications. With the help of the strategies that the acceptance of the economies of scope presupposes, Xerox and the U.S. Telecommunications can develop into larger corporations, keeping their integrity and creati ng the environment auspicious for further improvements and progress. Executive Summary In the modern world of economics, the aspect of technological innovations plays one of the major roles. Providing an efficient operation of companies, facilitating the work of the employees and simplifying the working process in general and certain operations in particular, the technological aspect is one of the prior issues in the sphere of economies of scope. Hence, the scale of the recent technological innovations, as well as their impact on the modern economies of scope, is to be considered. In addition, the general features of the modern examples of economies of scope are to be observed as well. Narrowing the research to featuring the peculiarities of several entrepreneurships, the strategies chosen by them, the tactics the businesses in question implement and the goals that they pursue, as well as analyzing the commercial integrity within the companies in question, one can come to certain co nclusions concerning the methods in which the modern economies of scope are operated and the issues that arise on certain stages of the development of the given economies. Hence, the general assessment of the current situation in the sphere of economies of scope can be conducted. With the help of the specific methods of research, precise data can be obtained, a thorough analysis can be conducted, and cohesive conclusions can be made. In the given paper, several companies that represent the economies of scope and utilize the correspondent elements their corporation strategy are going to be considered, their recent technological innovations are going to be enumerated, and the changes that have occurred in the given companies are going to be analyzed. It is important to mark that the given research focuses on the technological innovations used in the process of operating the economies of scope, and argues that for the economies of scope, the recent technological innovations can be cons idered as an efficient means of tackling certain entrepreneurship issues, namely, the ones concerning the efficiency of the company, the quality of the products and the efficiency of the staff. Therefore, the given paper claims that the current technologies are to be incorporated for an efficient implementation of the strategies of the economies of scope. In addition, the issues concerning the technological sphere are to be considered in the paper. Moreover, the social complexities are to be taken into account. Conducting an extensive observation of the given entrepreneurships, the paper offers profound conclusions.
