Youth Unemployment in the UK

Unemployment is a macro-economic situation whereby people are ready to work at the current wage rate but because of the prevailing factors of production are not in a position to get placement.Advertising We will write a custom essay sample on Youth Unemployment in the UK specifically for you for only $16.05 $11/page Learn More International Labour Organization defines unemployed people as those who are aged over 16 years and are willing to work and have actively sought employment during the previous four weeks and do not have any paid job. There are various types of unemployment namely: Cyclical unemployment, Frictional unemployment, Structural unemployment, Seasonal unemployment, Voluntary unemployment and under employment (Seymour 2005). Cyclical Unemployment is a type of unemployment, which occurs because of decline in Gross Domestic Product (GDP) especially during periods of contraction/recession or any period when the economy fails to operate at its potential. It is controllable thus receives a lot of attention from macro-economic policy analysts. Additionally, it is characterised by temporary suspension without pay due to reduced demand of goods or services they produce and has to last for a period of seven consecutive days (Seymour 2005). Frictional Unemployment is unemployment resulting from people leaving jobs that they do not like and are searching for new employment or people whom either entering or re-entering the labour force to search for a job. Time lapses between separation and discovery of new job. Structural Unemployment represents unemployment caused by permanent shifts in the pattern of demand for goods or services or changes in technology. This requires the employees to undergo training or move to other locations to find new jobs (Seymour 2005). Seasonal Unemployment is a type of unemployment, which is caused by seasonal conditions affecting specific factors. For example, the agricultural sector is dependent on rainwater. Hence, during periods of good rains there will be high economic activities creating jobs while during periods of dry season there will massive unemployment due to less economic activities. Voluntary Unemployment is unemployment by choice experienced in most of the developed countries. This happens because of the unemployment benefits given by the UK government thus encouraging most youths to look for highly paying jobs. Therefore, in the short-run most of them remain unemployed. Such decisions by most youth have led to increased level of youth unemployment in UK (UK National Statistics).Advertising Looking for essay on business economics? Let's see if we can help you!

Therefore, if an individual works for less than six hours then they are underemployed. This is because the talent or effort is not fully utilized. It can a lso occur when an individual is working in a sector where their skills are underutilized (Seymour 2005). Most of the youth in UK are either working fewer hours such as part time while others work in sectors where their skills are underutilized (BBC News). Unemployment rate measures the unemployment level. It is the proportion of economically energetic people who do not have jobs (i.e. number of people who are unemployed divided by number of those who are in paid jobs or employed, excluding those who are economically inactive from both numerator and denominators) (UK National Statistics). Statistics of Youth Unemployment in UK Economists and the government have carried out several researches over the years about the youth unemployment rate in the UK. According to Labour Force Survey (LFS), youth unemployment rate in the year 2004 rose from 12% to 15% in the year 2008 (BBC News). The number of unemployed youth between the age of sixteen and twenty five years has risen in the current r ecession by over 4% since 2008 and then by over 5% in the year 2010. This means that the unemployment rate for people aged 16-24 years is now triple the rate for older people. The rate of unemployment for individuals over 25 years have also followed similar trajectory since 2004. Therefore, the unemployment rate for people over 25 years in 2010 was still lower than that in the early 1990 (BBC News). The Office for National Statistics (ONS) says that the unemployed youth aged 16-24 has risen more than one million, which is the highest for 15 years. The total number of people unemployed is 2.62 million, which is the highest since 1994 according to ONS. The youth have borne the effect of economic slowdown. Thus, out of the 2.62 million, 1.02 million are youth aged between 16 and 24 according to survey carried between July and September last year (HRM Guide 2012). This has led to people claiming job seekers allowance to rise by 5300 to 1.6 million last month according to ONS. The ONS sa ys that this is the highest rate since they adopted the comparable method in 1992 despite the slight change in basis of calculation (HRM Guide 2012). The Institute for Public Policy Research statistics have shown that the unemployment rate of youth aged 18 is 18.5% for boys and 15.3% for girls (HRM Guide 2012). This is the highest rate they have ever witnessed in the UK. It is attributable to the current euro crisis. According to Lord Stevens, the official statistics of the unemployment rate of the youth hit the one million mark for the first time thus more than a fifth of people aged 16 to 24 years do not have jobs (HRM Guide 2012).Advertising We will write a custom essay sample on Youth Unemployment in the UK specifically for you for only $16.05 $11/page Learn More Causes of Youth Unemployment in the UK Financial Crisis of 2007-2010 The financial crisis that began in the United States caused by the bubble burst in the real estate industry affected sev eral banks .It spread across Europe since most of the banks affected were multinationals with operations across Europe. This led to economic slowdown in the economy of UK. Thus, most of the firms scaled down there production capacity. Consequentially, employers are forced to lay off some workers or were not hiring any more employees (Ruhm 2000). The effect of such circumstances has led to the rise of rate of unemployment among the youth since they are continuously completing colleges and are unable to secure employment (HRM Guide 2012). The Cuts in the Public Sector The government has been reducing its spending over the years. The reduction in public sector spending leads to decreased demand of certain goods and services since the government is the biggest consumer in an economy. Therefore, due to the decrease in demand, the production sector has to reduce its production. Thus, some people become redundant leading to sacking. Some of the firms also stop hiring new staff or reduce th e number of people employed compared to when the factors of production were being fully utilized. Therefore, the cuts in public spending have led to increased unemployment rate of the youth over the recent years (HRM Guide 2012). Immigration from European Union Since the integration of the UK in the European Union, people are free to move from one member state to another. This encouraged many people to migrate from other member states to UK in such for employment or business purposes. This has led to reduction of summer jobs that were available to university students from UK since most of the jobs go to the immigrants from other member states. Hence, such factors have led to the rise of the number of youth who are unable to secure paid jobs (UK National Statistics). Lack of Required Qualifications Researchers have link the lack of jobs by youths to their poor performance there studies such as in GCSE English and Maths. Most of the students have also not been able to proceed with the ir studies to acquire the necessary professional qualifications required in the job market thus unable to secure employment. This is attributable to laziness from the part of the students to work hard in their academics. The support groups in conjunction with the relevant government sectors have been working hard to ensure the students work towards achieving the relevant qualifications required in the job market.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Influx of Goods from Euro Zone After the UK joined, the European Union this allowed non-restrictive trade between member states. Such an agreement has led to the rise of goods exported to UK therefore increasing competition. This has resulted in the decrease in the demand for UK goods thus the decrease in the productivity of UK firms. They have resulted in lying down of workers and reduction in number of people employed. Therefore, this is one of the major contributions in the rise of level of youth unemployment in the UK. Higher Taxation The taxation rate in UK is high such that the cost of production is high. This leads to decreased demand of products thus firms end up retrenching some of the redundant workers. Effects of Youth Unemployment in UK Increase in Crime The youth would need money for consumption for clothing, food or shelter and since they do not have paid job they feel frustrated and start blaming the society for their misfortunes, hence they end up resulting to crimin al activities to get money. Lord Stevens acknowledged this when he said that unemployed youth would fuel disorder in the streets since dissatisfied youth lack hope for the future. He said disorder like the one experienced last year is evidence of the disquiet of youth due to lack of employment (Poverty Site 2012). Increased Chances of Workers Experiencing Unemployment in Adulthood The continued rise in the rate of youth unemployment increases the probability of a worker experiencing unemployment in his adulthood. The result of this the rise of number of people unemployed thus leading to increase of people claiming job seekers allowance which an increase in government expenditure in terms of transfers which is not healthy for the economy (Poverty Site 2012). Loss of Productivity The youth are the most active people in the society therefore when they are not employed statistics show that this equates to 10 million pounds a day of lost productivity. This translates to a direct cost of unemployed youth of close to 5 Billion pounds annually. Such statistics are worrying since this is a lot of potential wasted. The high levels of unemployment lead to too many people being idle thus high loss of productivity in the overall economy (Poverty Site 2012). Increase in Dependency Levels The rise of levels of youth unemployment has led to high levels in dependant population since they need basic human needs but do not have any source of income. Therefore, the rise in unemployment has increased the number of people depending on the government allowances for job seekers thus increasing the government expenditure. Responses Replacement of Future Jobs Fund with Apprenticeship Scheme The labour Party government initiated the Future Jobs Fund policy. It aimed at creating jobs in the future for the youth. The Conservative –Liberal Democrat coalition government viewed this not to very effective method to address the menace of youth unemployment. It replaced it with the curre nt policy of apprenticeship scheme whereby the youths attached to organizations where they will be working under skilled workers thus they end up acquiring necessary skills. This policy will be more effective in solving the youth unemployment problem than the future jobs fund. Overhaul of Schools Career Guidance The Recruitment and Employment Confederation have proposed an overhaul of the school’s career guidance to encourage students to work hard to acquire the necessary skills for job employment. This encourages students to achieve the necessary professional qualifications necessary for employment. Such policy will lead to students being prepared to join the apprenticeship scheme thus improving the level of youth employment. Scrapping of National Minimum wage Dominic Raab called for the scrapping of National Minimum Wage for the 16-21 year olds people thus increasing the level of youth employment. The minimum national wage is a hurdle to organizations since they incur certa in expenditure thus they end up being limited on the number of employees employed. Therefore, the scrapping of the minimum wage will lead to firms employing more people thus reducing the level of unemployment (Poverty Site 2012). Entrepreneurship Encouraged The government and non-governmental organizations have been implementing programmes that instil entrepreneurship skills in people. Such programmes have led to an increase in the level of people who are self-employed. This has led to rise of people who are self-employed in the UK over the years. It has been a very effective method of addressing the problem of youth unemployment (The Guardian 2012). Reference List BBC News, Economy Tracker. Web.

Interwar Essay Example | Topics and Well Written Essays - 750 words

Interwar - Essay Example Everybody concentrated on war, which subsequently bred mistrust among countries thereby paralyzing conducive relationships for business. Such precarious times discouraged effective economic activities resulting in a number of world economic disasters. One such disaster was the Great Depression; countries had concentrated all their efforts on the war. Countries had spent billions of dollars purchasing firearms and in the training soldiers, nobody at such times considered the economic repercussions of the exorbitant military spending that the world’s major economies such as the United States of American and the Soviet Union had undertaken. It is only after the war that the countries realized that they had spent more on military at the expense of other sectors of the economy. Furthermore, the war had bred unfriendly relationship between the countries. The regional alignment of countries resulted in the East locking themselves away from the Wets thereby curtailing all business rel ationships between the countries. ... â€Å"Before the war, while most European countries had acquired the constitutional governing systems of some kind, many of these were actually far from being actual democracies† (Martin 312).This implied that the countries had weaker economies and could not possibly afford the cost of the war. However, their participation on the war were inevitable and most countries invested larger amounts of both financial and human resources on the war at the expense of the economy. Combining the political instability of such countries to the implications of the war therefore resulted in a chaotic and unsustainable economic system thereby resulting in the great depression. The First World War lasted for three years a period within which minimal economic activity took place. The world took place in several battlegrounds such as Japan, Italy and Germany and in a number of countries within the Soviet Union. During the wars, such regions therefore became inaccessible and unconducive for any ec onomic activity such as either agriculture or trade. Furthermore, the concern of most governments was on how to save the civilians some of who were dying from the effects of the war and hunger. Three years without a reliable economic activity was likely to bear serious consequences on the countries including those not directly affected by the war. Countries therefore resorted to radical economic policies in the period preceding the war in an attempt to uplift their dwindling economies. The USSR for example implemented a five year plan through which it sought to revamp its economic power and in so doing alleviate the living standards of its people. â€Å"The party

The relationship between Entrepreneurship and Economic Growth Coursework

The relationship between Entrepreneurship and Economic Growth - Coursework Example In the modern business world, an entrepreneur can be defined by a number of definitions based on past empirical analytics & researches - an innovator, a leader, a manager, owner of an enterprise, coordinator of economic resources, resource manager, provider of capital, improvement of service levels, enhanced image of the economy on a global platter, and so on. But above all, fundamentally an entrepreneur is the person who has the guts to start and run a business as per the ideas generated by innovations. Entrepreneurs impact the local economies by increasing the diversity, invoking competition, creating jobs, managing social empowerment & practicing Change Agentry, increasing tax revenues, improving existing products & services, etc. and hence overall value adding to the economic performance, productivity and internationalization of the nation. A simple model of the relationship between entrepreneurship and economic growth is presented in the figure below (Figure 1): Figure 1: A simple model showing relationship between Entrepreneurship and Regional Economic Growth (Source: Gleave, Bill Dr. University of Essex. 2007) Entrepreneurs are expected to generate new ideas by virtue of innovations which may comprise of: 1 (a) Introduction of a new product (b) Introduction of a new technology (c) Introduction of a new methodology of production (d) Opening a new business potential & market in the region which has remained untouched largely (e) Discovery of a new source of supply of raw materials, support & services (f) Building a new organization system with innovative business model (g) Create new profit opportunities These opportunities lead to overall... An innovative entrepreneur is expected to possess high-risk appetite when starting a venture. Intelligent entrepreneurs clearly understand the correlation between risk & uncertainty which can be calculated by applying known probabilities and impacts. Knowing the dynamics, the entrepreneurs shall take calculated risks into account to bear the uncertainty of production & trade – the payoff is the profit earned by the entrepreneur which forms the primary motive anyway. A venture capitalist plays the role of trusting the risk appetite of an entrepreneur and funding him/her to help in transitioning the ideas into action thus forming good performing start-ups. A country having an effective framework of capitalists (Banks, Financial Institutions, Private lenders, etc.) ensures better development of entrepreneurship thus boosting the economic growth. This paper critically evaluates the correlation between Entrepreneurship and Economic Growth and the corresponding factors prevalent in the region influencing this relationship both on the positive as well as negative sides. Also, this paper intends to look at what measures of entrepreneurship are being used and discover whether the measures are appropriate. 4 Bosma, Neils and Harding, Rebecca.

Developing YORKLAB HR strategy Essay Example | Topics and Well Written Essays - 3250 words

Developing YORKLAB HR strategy - Essay Example The company tries to retain its customers by ensuring timely delivery of goods which in turn enables to ascertain growth for the company throughout the year. Yorklab follows a flat organisational structure, which ensures a wide span of control with fewer level of management. The structure allows the company to be less costly, with less management levels. This structure will ensure a better and quick flow of decision within the organisation. Moreover, it will have a fast and clear communication of messages from the management ensuring timely and quality product. This structure helps the company to keep a proper track of the sales and the services provided. The HR policy of the company facilitates in employing people who have knowledge regarding the process and are friendly and ready to work in team. Satisfying the customer is the primary motive of the company and this is the core reason for the success of the organisation for years. The company is in the need to expand its business in to new areas of the market. In this context, the management realises that the current HR system or management structure will not be able to sustain the market growth. The HRM concept used is to bind the employees and the management to achieve the goal of the company. It entails the planning, controlling and organising the employees to add value to their service and achieve the desired objectives. In this regard, the objective of the paper is to explore the efficient structure requirement of the company, to mitigate the issue related with the market expansion. The upgraded HR strategies are required to be implemented by the Yorklab in order to attain profit and growth in the market. HR Strategy Content Human resource management is a strategic approach on managing employment and relation in order to achieve competitive advantage. The competitiveness of a business depends on the manager, employees and the knowledge and training provided. Yorklab in this regard followed the flat structu re of management, with a few number of employees and a wide span of control. This structure had various advantages such as the fast communication of information and quick decision regarding the process improvement. The fewer strata of management also help Yorklab to have a better recurrent communication between the higher level of authority and the staff. The purpose of the company is to expand its business keeping in view the quality and the level of customer satisfaction. This was not possible with the current flat HR strategy used by the company. As the level of guidance and coordination between the management and the employee was less there was no proper co-ordination. With the expansion of business, the current number of employee would not suffice the need of the company. With the increase in the business activities, the complexities would increase and the current flat structure would not support the requisite. The flat strategy with wider span of control renders less amount of time to focus on the individual decisions. This can thus be of a great disadvantage for taking significant strategic decisions which will have a long-term impact on Yorklab (Education-Portal,

The Perimeter Network Security System Computer Science Essay

The Perimeter Network Security System Computer Science Essay As like in the real life, securing the borders are the first level of defense to protect the internal network of an organisation. The purpose of this report is to design a perimeter network security system that will provide security enhancement on the existing network infrastructure of Napier University. Network perimeter is an important line of defence in an enterprise network and every organisation has this perimeter network. Perimeter network is where the internal network meets the border network. The main security architecture using this potential area of the network is firewalling. Here this report discusses the egress and ingress filtering of packets by the firewall in order to let the bad traffic out of the perimeter and allow only the good traffic to trusted internal network. One of the core ideas behind the securing the network from outside threat is to develop and implement multiple overlapping layers of security solutions with different security components like Firewalls, VPN, IDS/P and Proxying. Though there are no single security solutions to protect the university network, multiple layers of perimeter security solution will provide maximum available protection from both outside and internal threats. (Watkins, 2011) The design considers hardening of network devices by striping down unnecessary protocols and services and manages the security perimeter from a management network for proper monitoring and mitigation. The main challenges to design and implement a perimeter security is to determine the proper firewall design, as Perimeter firewall and border routers are key components that decide the security to internal network. Most modern day attacks are happening in the Application layer and filtering in this top layer is extremely important for a successful security design. An enhanced packet inspection with proper monitoring and reporting is required throughout the end points of the network to block the malicious traffic from in and out of the network. There are number of ways and techniques involved in designing a perimeter security and this design proposes the specific solutions to the security threats in a campus wide network than in a highly complex enterprise network. 1 CSN11111 Perimeter Network Security System 10800584 RESEARCH AND DESIGN (25/ 1000 words) Security is not a product but a process. Network security depends on multiple components, policy and procedure to enforce the best practices on systems, people and infrastructure (Michael E. Whitman, 2009). The basic idea of information security is to protect the three fundamental components of information security that are Confidentiality, Integrity and Availability. Perimeter security design follows this principle to protect these components by using various security components. The design of the perimeter security depends on what resources need to be protected and the business need. SECURITY ARCHITECTURE The main design of the security architecture consists of segregating different zones in a network. These zones have different levels of security trust levels that allow or deny traffic. This layered architecture will provide the University to keep out of attackers (the term attacker is used in this report and not hacker, as an attacker is a hacker with a malicious intent and not all hackers are malicious intent). In the enterprise network, the network is divided generally into three zones and these are Border Network, Perimeter network and internal network. The perimeter security consists of border network and perimeter network as shown in the picture. Each of these considered as single entity against potential threats. In a network perimeter has many points where an effective security policy should be established. The network perimeter is the most important points of security against 2 CSN11111 Perimeter Network Security System 10800584 external threats. Many types of security can be implemented like packet filtering, intrusion detection systems/prevention and anomaly detection etc. Border Network Border network is the Internet facing zone via a border router (Edge router) that provides an initial layer of protection against all the starting point of attacks. It is most likely an IDP (Intrusion Detection and Prevention) System to be placed to create an extra layer of security. The border router will allow the traffic as per the Ingress and Egress filtering rules set on the router. Apart from protecting the outside threats these edge router and IDP also help to reduce the network load on the perimeter firewall by filtering spoofed traffic out of reaching to the perimeter firewall. Egress filtering helps to prevent specific types of traffic going out of the University that may be some confidential information or can an attacker plant traffic from a payload. A common rules used in the border router is to filter out the ICMP traffic to avoid the probing of network infrastructure. (Dailey, 2009) Perimeter Network Perimeter network sits in between the Border network and the trusted internal network often referred as DMZ. A Perimeter Firewall is the main component to filter the traffic to DMZ and passes the traffic to internal network. This firewall allows traffic from outside the network to servers like Web server or Email Server and also allows a limited access from the internal users. 3 CSN11111 Perimeter Network Security System 10800584 Perimeter firewall allows the filtered traffic to internal firewall where traffic is further scrutinised by the set of rules according the security policies of the organisation. These firewalls are commonly uses the stateful inspection technology where the states of legitimate traffics are stored in the firewall cache. Only traffic matching the states of the connection is allowed and others are dropped. REQUIREMENT ANALYSIS When designing a secure network there are number of factors are taken into considerations. Security is not just a technical issue but a business issue. The goal is to make sure a balanced approach towards the requirements in general. The general security requiement is to provide the services according to the CIA triad of the information security. Apart from these there are also factors like budget, existing infrastructure and scalability. Other factors also constitute the decision making of a proper design are reduce cost, employee productivity, avoid business down time, comply with industry standards etc. SECURITY THREATS This section discusses the better known attacks and the reason behind using perimeter security as first line of defense. Attacks can be devided into external attacks- coming from the internet and internal attacks- coming from the internal network. Information Gathering is the first method an attacker try to get the maximum informaiton about the network architecture. 4 CSN11111 Perimeter Network Security System 10800584 The external attacks are from the simple probing of the network to DoS( Denial of Service Attacks). An insider attack considers one of the major threats to any perimeter security design. These attacks may come from a mischievous user to a disgruntled employee who wanted to grab confidential information or to steal company secrets like financial data, personal information etc. A well configured internal firewall along along with the perimeter firewall can be the good level of defense against these attacks Other types of attacks inlcude intrusion packet sniffing, IP spoofing and DoS attacks that poses a direct threat to the organisation. Application layer security is one of the important design area to be take care of. Well known attacks like SQL injection are of these types. These exploits the known or unknown vulnerability on a web server or database server in order to gain the unauthorised access to the internal network. DESIGN The design of each of the security zones for the Napier University may be different but as whole these components acts together to provide a common goals by protecting the perimeter. It is important to understand where the perimeter of the network exists and what technologies are used against the threats. Perimeter security is handled by several different technologies including border router, firewalls, intrusion detection sytems and prevention systems, VPNs. Border Router The border router sits in the border or the edge of network where there is a direct interface to Internet. It acts like a traffic policeman, directs the traffic in or out of the network and also block the traffic which are not allowed to. The border router will do a NATing to provide this feature. This will give the outside network to probe the internal network. Although these routers are do not act like a firewall, it helps to protect the very first line of defense. Firewall 5 CSN11111 Perimeter Network Security System 10800584 A firewall is an active device that job is to permit or deny the data packets as per the rules set or the states of the connection. Perimeter firewall is the center point of defense against all the threat that coming to internal network. Firewall can be software based or hardware based hardned for the filtering of packets. The proposed perimeter security can be stand alone or multiple layers that combined with other security devices like IDS, IDP and VPN. A static filter firewall is the common and simplest firewalls. These firewal allow or block traffic based on the packet header. A perfect example is blocking of Spoofed IP traffic. The main advantage of this type is that I has a very fast throughput but the down side is this firewall block already established connection which may be malicious intent. On the other hand the stateful inspection firewall is the best way of defending the maliciuos attacks. Stateful inspection firewall keeps a copy of the state of each connection so that the traffic will be allowed or denied according the states in the state cache maintained in the firewall. The disadvantage of using this firewall is slow traffic coming out of the firewall as invidiual packets need to be verified and checked with the cache table. Another firewall which is effective against the application layer attacks are the Proxy firewalls. Since the most modern day attacks are pointed against the application protocols the stateful or stateful firewalls will not block the malicious traffic coming to/out of the network. A proxy firewall acts in the middle of the internet and private hosts and the proxy by acting on behalf of the host. The filtering rules are applied in the application layer. The ruleset or signature can be created according to the latest threats. Because of the huge number of traffic these firewalls considered the lowest throughput than any other firewall but top end in droping unwanted malicous application layer traffic. A web application filter and a spam filter are the example of a proxy firewall. DMZ A DeMilitarized Zone or DMZ is the separate zone from the perimeter firewall between the external network and trusted internal network. The public internet facing servers like Web servers, email servers are placed in this area because the DMZ is considered the the most sensitive area with high security stance. The firewall restrict the traffic in this zones in order to avoid the potential threats that may come into the internal 6 CSN11111 Perimeter Network Security System 10800584 network. The network inside this zone cannot initiate a session to the outside world unlcess it is a reply to an incoming connection. Intrusion Detection Systems (IDS)/ Prevention systems (IPS) An intrusion detection system or prevention system works in sync with the firewalls by providing a coming security goal of blocking unwanted traffic and notify any event that pop up in the network or host. IDS anlayse the packets for any suspicious activity and alerts the administrator. An IPS will prevent these activity by droping apart from the detection the same way IDS does. IDS and IPS have extensive rules set or singnatures of malicious activity which matches the incoming or outdoing traffic when in operation. One disadvantages with the IPS or IDS is that it may alert an legitimate traffic which considered false positive. A proper configuration of these devices is required in order to kept the false positive minimum as some times this will be a menace to handle too many logs with many thousands of false positives. A host based IDS also provide the security administrator with alerts against he malicious activity destined against a particular server like in Database server. VPN Virtual Private Nework (VPN) establish a secure remote connection to the private network by creating a secure virtual tunnel through the public untrusted network. VPN provides perimeter security by ecrypting the data in the tunnel and establish a secure connection over the internet. VPN considered to be the potential threat when an attacker comprise the tunnel as the traffic cannot be verified by the IDS or IPS because of the encrypted pakcets it uses for communication. An SSL VPN with an end-to-end VPN can be the best possible way to stay the attacker out of the network. A perimeter security design is incomplete without a proper firewall policy and an organisation wide security practices. For example if an administrator keep a weak password for these devices or any hosts in the network can nullify the entire effort put on designing a perimeter security. These security policy should also be applied to 7 CSN11111 Perimeter Network Security System 10800584 systems, and users as there needs to be a minimum level of secure access policy with proper Authentication, Autherisation and Authentication(AAA) methods. http://www.cisco.com/en/US/products/sw/secursw/ps1018/products_tech_note09186a00808bc994.shtml Management Network Management and logging is the most important aspects of a perimeter security. This network has the high security stance as all the administrative access are controlled in the management network. An attacker can take direct access by accessing the management network. The traffic to management network to be encrypted to avoid any possible attack on the internal network. For example to access the IDS, ISP and or routers to be through a secure shell, or SSL, or a https access. Log monitoring is another important aspect of a perimeter security like keeping the IDS and IPS logs or firewall logs. Log files can help to identify the probable attack on the internal or malicious activity originating from the internal network. Another possible thing to do to harden all the security devices destined to do only services that (Convery, 2004). IMPLEMENTATION (20/ 800 words) Building a perimeter security system consists of bringing different security technologies explained in the previous topic; together for a common goal-to protect the internal network from external or internal threats. The router and firewall separate the public untrusted network from the internal network, the IDS/IPS monitors all traffic, and the VPN provides remote access. All of these components together form a defense in depth security in a perimeter. Figure xxx shows the outline prototype of the proposed design. 8 CSN11111 Perimeter Network Security System 10800584 authentication server-dmz One of the first best practices before the implementation is to develop a firewall policy. The policy mainly defines the security trust levels of each zone in the network and the flow of the data traffic. The flow of data traffic is one of core in implementing the organisation wide security technologies. Perimeter firewall is the centre point in this prototype. This firewall is a stateful inspection firewall and manages traffic from external and internal network. This firewall is a closed security stance by blocking all traffic except those required for the University network. 9 CSN11111 Perimeter Network Security System 10800584 The figure - above shows how the data flows through different layers of security first where the first line of defense is border router. This multiple layers of security filter the bad traffic in different layers in the network. The first level of defense is border router with a backup from the NIDS. This can be implemented by enabling basic packet filtering rules and Access Control Lists. Blocking the IP Spoofing and ICMP traffic are the examples. This outline NIDS will detect the any unknown behaviour in the traffic, which will be alerted to the administrator through management network. In some cases border router may not required as the perimeter firewall it self can handle the security threats but that depends on the business decision like cost and availability. Diagram for flow of trafficà ¢Ã¢â€š ¬Ã‚ ¦ As shown in the figure the data flow in the perimeter firewall. Perimeter firewalls allows or deny traffic as per the ingress and egress filter rules. Almost all the traffic coming to the internal network will be blocked by firewall and only allow as per the egress rules. The exception for this rule is for VPN clients and the VPN uses the encrypted tunnel and the VPN server is inbuilt in the Firewall itself. The Perimeter firewall also allows ingress traffic to DMZ zone but drop traffic originates from the webserver other than the reply to the already established connection. DMZ is the least trust level and this is why DMZ is isolated from other network zones. The internal network is allowed to access the Internet and Intranet through a proxy server in the DMZ zone. A web filtering software in the Proxy server can be implemented to filter out the unintended malicious URLs and links. The DMZ also has an inline NIPS in order to defend attacks against the application level threats like DoS attacks. The in line IPS behind the Perimeter firewall act like a sub-cop to check the malicious activity originating both from external and 10 CSN11111 Perimeter Network Security System 10800584 internal network. Internal threat may come from a disgruntled employee or a malicious traffic from a Trojan program or a zombie for a possible DDoS (Distributed Denial of Service) attack by a hacker (black hat off course!) harvested by using techniques like social engineering. The table explains the detailed egress and ingress rules on the Perimeter firewall. TRAFFIC TYPES INGRESS EGRESS ALLOW HTTP/S Request, DMZ Allow ICMP DMZ Deny Email (SMTP) Request DMZ Allow Email (Exchange RPC) DMZ Allow All Other Traffic DMZ Deny HTTP Reply DMZ Allow SMTP Reply DMZ Allow Exchange RPC Reply DMZ Allow All Other Traffic DMZ Deny ICMP (depends on policy) Internal Network Deny Remote VPN Connection Internal Network Allow All Other (Including from DMZ) Internal Network Deny Proxy Server (Port 8080)- Internet Internal Network Allow Email Server Access (DMZ) Internal Network Allow ICMP Internal Network Deny All Other Traffic Internal Network Deny Management network in the proposed diagram is one of the top security trust level where the management of all the security devices can be done. Log analysis, Secure tunnel access to routers, firewalls, IDS/P are all done in this network. The trusted servers in the internal network are protected with an internal packet filter firewall with only few of the protocols and ports are allowed. This will give the server farms with highest level of security. The staff and student networks are segregated with VLAN, as staffs should have access to student network but not vice versa. VLAN separate the traffic like a router and this will be important when considered in a University network. 11 CSN11111 Perimeter Network Security System 10800584 Both staffs and Students can have access to trusted servers through the internal firewalls. The NIDS is also monitor any suspicious event and alerted. The other Host based IDS and personal firewall in each of the workstations provides an extra layer of security. So the proposed design with a defense-in-depth can be implemented to enhance the existing infrastructure of the Napier. TESTING AND EVALUATION (25/ 1000 words) 12 CSN11111 Perimeter Network Security System 10800584 CONCLUSION (15/ 600 words) Unifiied threat management Appliance emerging cobbà ¢Ã¢â€š ¬Ã‚ ¦. One persons good enough is another persons never! Bandwidth for authentication is trivial in any case I can think of that doesnt include downloading extremely large biological mappings of the authentication target. As far as security measurements, I dont know what yard stick youre using, but strong on-host, per-host authentication works well when you have a trusted path, everything else is a usability or management compromise, I dont think Id tout them as security features. Placement of authentication server Placement of internal firewall. http://www.sans.org/reading_room/whitepapers/firewalls/achieving-defense-in-depth-internal-firewalls_797 he single, authenticated/anonymous, and individualized DMZ designs are all secure designs that provide the best protection for various network sizes. The single DMZ is respected for its simple design which separates itself from a private network. The authenticated/anonymous DMZ classifies servers and the data they protect in order to segregate servers that need strong access controls from the ones that do not. The 13 CSN11111 Perimeter Network Security System 10800584 individualized DMZ gives the greatest security for a mature network, but also has the highest setup and maintenance costs. All of these secure DMZ designs are susceptible to a poorly configured server which can allow a criminal access to a data store or worse, the entire private network. In a nutshell, theres no such thing as absolute security. How much you invest in firewalls should be a function of how much you have to lose if an attack is successful. (reword) You probably heard a number of so called security experts claim the perimeter is dead because it is not effective at blocking attacks. Nothing cluld be further from the trust. Its true that attacks have become far more complex. The concern is no longer simple port scans. What we need to do however is enhance our posture, not scrap useful technologies. To be fair however, its not just the perimeter that is having the problems with modern attacks vectors. Tools like metasploit have reduced the time of exploit development from days to minutes. Networks are being spear targested with Malware which goes undetected by their Antivirus software, in some cases for as long as two years. Attackers have figured out that they do need to completely defeat forensics, they just need to make it difficult enough that it is no longer cost effective in a CFOs eyes to fully analyse the comprosmised system. So the true problem is attack technology is advancing and we need to keep up. Sometimes this is finding new security technologies and sometimes its by retasking the ones we are already using. To draw a parallel, think of what has happened with the common automobile. 40+ years ago a tuner could tweak more power out of an engine with a simple toolkit from sears. Many of those old times tuners will tell you that engines are now too complex t work on. T o the modern tuner however who is willing to add things like OBD-II adapters and laptops to their toolki, the payoffs are huge. Power levels that used to equire huge V8 engines can be produced in tiny four cylinders with as much displacement as half gallono fmilk. 14 CSN11111 Perimeter Network Security System 10800584 https://ondemand.sans.org/b20080814/viewer.php?mode=2lo=7652moduleid=530 7pos=0hint=1#viewer Properly configured firewalls and border routers are the cornerstone for perimeter security The Internet and mobility increase security risks VPNs have exposed a destructive, pernicious entry point for viruses and worms in many organizations Traditional packet-filtering firewalls only block network ports and computer addresses Most modern attacks occur at the application layer 15 CSN11111 Perimeter Network Security System 10800584

The Rabies Virus and Treatment Essay -- Biology Medical Biomedical

Rabies Virus and Treatment Rabies is a virus that is characterized under the family name Rhabdoviridae and genus name Lyssavirus which travels to either the brain or the spinal cord, where it attacks a victim's nervous system until death occurs as discovered by Pasteur. It is rabies unique bullet-shaped body and tubular extensions, along with its specialized proteins that contribute to its deadliness. Aside from one case of rabies that occurred in 2004 in Wisconsin, rabies has proven fatal; there is no real treatment besides prevention. Vaccinations and precaution serve to be most effective pre-exposure, while post-exposure treatment can be a combination of respiratory and cardiac support, and intensive care. As part of the Rhabdovirus, Rabies is similar to 75 other viruses, but only closely related to 5, which are believed to have originated in Africa. Each year, around 7,000 cases of rabies are recorded according to an article for parents on Kids health website, but because of vaccinations, only one or two die. All, including Rabies virus, have a bullet shaped body accompanied by â€Å"bizarre elongated filaments V or Y shaped†(Kaplan, et al. 2). Once the rabid viruses infect the blood stream, they begin their migration to the brain where the virus begins to multiply effectively and abundantly in cerebral matter, producing defective interfering particles, as described in the book Rabies by Kaplan, Turner, and Warrell. Like many other viruses, rabies has an excellent way of transmitting itself, allowing it to be efficient-saliva. While it is true that simple UV rays found in the sun can kill the virus in a dead body laying around, as well as acidity and soaps, because organic matter like soaps are able to dissolve the virus’ out... ...y day, doctors look for new and more effective methods of treatment, looking for solutions in vaccinations and in the infamous G protein, but again, prevention is key.
