When one is stressed out they may feel like they just want a place of comfort, or a peaceful place in their mind that makes them feel good. For some to feel thi s way they turn to activities such as drinking, and smoking. Every year more than 300,000 kids under the age of 18 start smoking. Also, some researchers from â€Å"BBC News† stated that alcohol and smoking combined, greatly reduce the sperm count of a young male. The more they smoke and drink the lower count, combined with marijuana there is a very small chance of getting a girl pregnant. Researchers from â€Å"BBC News† also stated that only 17% of kids under 18 years old indulge in tobacco products. Young people consuming all kinds of substances is drastically growing each and every year. For some teens peer pressure, curiosity, and also stress can all play major roles in why one might choose to indulge in alcoholism and smoking.

Huck and Jim in Adventures of Huckleberry Finn Essay

A flat character is one that stays the same throughout a book or story, and a round character is one that changes throughout the book due to challenges they face and resolve. While Huck and Jim are two very important characters throughout the book, it could be argued that they are flat or round. Neither change very much, but each have small discoveries. Throughout the book, Huck is independent and easy going. He never wants to be kept down or tied to one place. Even though he is the main character, he does not change very much during the book. Even at the end, he refuses a home saying, â€Å"She’s going to adopt me and civilize me and I can’t stand it. I been there before.† (Twain, 338.) Huck could have had a home with Aunt Sally, but chose†¦show more content†¦Jim is also a relatively flat character. He goes through the novel with very little change in his character. He is always superstitious, but also is very accepting of people. One example of his s uperstitions is, â€Å"And [Jim] said that handling a snake-skin was such awful bad luck that maybe we hadn’t got to the end of it yet.† (Twain, 64.) Jim always adheres to his superstitions, and in a way they govern his life. Even when Tom and Huck are attempting to set Jim free near the end of the book, Jim goes along with all their crazy machinations. This is similar to his superstitions, because he is willing to do silly things, since he believes they are essential to gaining freedom. Just as Huck does make some changes, so does Jim. At first Jim is willing to accept the â€Å"king† and the â€Å"duke.† But, after having to deal with all their schemes and the way they tie him up and are rude, Jim wishes they were gone. He tells Huck, â€Å"I doan’ mine one er two kings, but dat’s enough. Dis one’s powerful drunk, en de duke ain’ much better.† (Twain, 158.)

Virtual Private Network (VPN) Computer Networks

Question: Discuss about the Report for Virtual Private Network (VPN) of Computer Networks. Answer: Introduction A virtual private network (VPN) is an expansion of the corporate network linking the companies and remote employees at different geographical areas through public networks like internet so that secure network connection establishes [1]. The term virtual is used in the sense that the physical network is not held by the individual user of the network but it is the public network. The term private is used to indicate the privacy of the traffic flow over VPN. This report discusses the implementation of two types of VPN Multiple business sites and Tele worker. The functionalities, security features, advantages, disadvantages, applications, extension of the network are discussed. Virtual Private Network (VPN) and types For expansion of the companys computer network, beyond its local geographical area, Wide Area Network (WAN) can be used. WAN uses leased lines like ISDN and Optical carrier to provide network coverage [13, 14]. The major advantages of WAN over Internet are performance, security and reliability. But the drawbacks of WAN are that the installation and maintenance of WAN is expensive, particularly if the distance between the remote offices increases. Hence, now-a-days companies build their own Virtual Private Network (VPN) which is a easy solution to the installation and maintenance cost. In VPN, secured virtual connections between remote users are routed through the Internet via the companys private network instead of dedicated leased lines. The major advantages of VPN are reduced operational costs, improved security, scalability, reliability and simplified network topology. Figure 1 illustrates the structure of Virtual Private Network. There are two types of VPN Remote Access VPN and Site-to-Site VPN Figure 1 Illustration of Virtual Private Network Site-to-Site VPN with GRE Tunnels Implementation (without IPsec protection) Companies located at different sites are connected through Site-to-Site VPN over Internet. It is of two types Intranet VPN and Extranet VPN. Intranet VPN permits connections between LAN to LAN to connect the same company located at remote locations. Extranet VPN permits connections between LAN to LAN to connect a company with another company which is in close association, like partners so that a collaborative environment exists [15]. Figure 2 shows the network diagram of site-to-site VPN connection. Figure 2 - Network Diagram of Site to Site VPN connection The VPNs use the mechanism of tunneling for transmission in the network. An entire packet is placed within another packet and sent over the network. The interfaces where the packet enters and leaves the network are called tunnel interfaces. Three protocols are used in tunneling. Carrier Protocol is used by the network Encapsulating Protocol which is used to cover the original data Passenger Protocol used to represent the original data In Site-to-Site VPN, Generic Routing Encapsulation (GRE) is the protocol generally used for encapsulation. Generic Route Encapsulation (GRE) encapsulates the packets with a GRE header and the packets travel inside a GRE tunnel. They are not encrypted by GRE. The Point-to-Point (PPP) protocols at layer 2 used in remote access VPNs for tunneling are Layer 2 Forwarding (L2F), Point-to-Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP). Security Features Firewall acts as a barrier between the secured internal network and the public Internet which is not trusted [4]. The type of packets to be passed through the network, the number of open ports and the protocols to be allowed are restricted by the firewall. VPNs provide secured connection between two remotely located sites. A combination of firewalls and VPN establishes both trust and privacy between the two sites. Authentication, Authorization and Accounting (AAA) servers provide secured connection for Remote Access VPN [9]. Authentication checks for the valid user, Authorization checks for the granting of services which may be restricted, and Accounting checks for the consumption of network resources for billing, planning etc., Advantages Low cost of VPN with no use of leased lines. Scalability that means adaptability if the organization grows. Disadvantages Security Issues arise since the data packets are not protected by GRE. Different vendors use different VPN technologies and they may not be compatible. Applications Suited for organizations which have geographically separated offices and virtual connections established in the network with less attention to security issues. Site-to-Site VPN with GRE Tunnels using IPsec ESP Implementation IPSec, which is layer 3 protocol, is suited for both remote-access and site-to-site VPNs. If the data packets encapsulated by GRE are to be protected, IPSec must be configured. Then the GRE tunnel is converted into a secure VPN GRE tunnel through the addition of IPSec. With the use of Generic Route Encapsulation (GRE) tunnels in addition to IPSec, Multi Protocol traffic can be carried between the two sites. It also enables the end stations to use private address space rather than registered IP addresses by means of encapsulating the IP packet in tunnelling protocol. It is illustrated in Figure 3. Figure 3 - Generic Route Encapsulation as the carrier protocol of IP The payload of an IP packet is encrypted using Encapsulating Security Payload (ESP). It is illustrated in Figure 4. Figure 4 IPSec Encapsulating Security Payload The header provides the protocol carried in the payload. The encryption transforms used in ESP are Data Encryption Standard (DES) and NULL encryption algorithms. Security Features Through Internet Protocol Security (IPSec), better encryption algorithms and authentication schemes are provided [7]. Encryption is the process of encoding the data to be transmitted into a form such that only the intended computer will decode the data [10, 11]. There are two types of encryption Symmetric-key encryption and Public-key encryption. In Symmetric-key encryption, the same private key is used by both the sender and the receiver to encrypt and decrypt the data. In public-key encryption, public key is used for encryption and private key is used for decryption. There are two encryption modes in IPSec Tunnel and Transport. The payload alone is encrypted in Transport mode while both the header and payload are encrypted in Tunnel mode. Data transmitted between various devices such as router-router, Firewall-router, PC-router and PC-Server are encrypted by IPSec. Advantages Low cost and scalability. Flexibility for business partners to have secured virtual connections to the network. Secured communication among the users. Disadvantages VPNs require a thorough understanding of the security issues of the public network and proper methods have to be deployed to overcome the issues. Implementation of VPNs needs additional protocols other than IP and hence they should be able to accommodate them. The performance of the VPN and its availability largely depends on external factors and hence not able to control. Applications Suited for organizations which have geographically separated offices and secured communication between them is an essential criterion. Remote Access VPN (Telework connectivity) without cryptographic technology It is also called Virtual Private Dial-up Network (VPDN). It enables the remote employees of the company to be connected to the private network through Enterprise Service Provider (ESP). The ESP provides a Network Access Server (NAS) and the desktop client software is used by the remote users to access the corporate network. Figure 5 shows the network diagram of Remote Access VPN. Figure 5 Network diagram of Remote Access VPN A NAS is the server which connects the user with the internet and provides access to the VPN by valid user authentication. The tunnelled connection to a Network Access Server is set up by the client software by its Internet address. Advantages It incurs low cost for the implementation of remote access VPN. Remote workers can easily communicate with the office. Disadvantages Security Issues If the computer used to connect remote access VPN is not provided by the company, it is susceptible to security issues like virus which may also affect the company network [5, 6]. Applications Remote-access VPN uses public network like internet to access the organizations network. Hence they are largely employed where the remote employees uses wi-fi or other technologies to access the internet and get connected to their corporate network. Secure Socket Layer (SSL) VPN for remote access IPSec or SSL is used by the remote-access VPN to establish secure connection to the network [3]. SSL VPN can be used with the standard web browser which does not require the installation of specialized client software as in the case of IPSec. It allows the remote users to access the client/server applications, web applications and internal network applications. SSL protocol or Transport Layer Security Protocol (TLS) is used to encrypt the traffic between SSL VPN device and web browser. Advantages SSL VPN provides secured network access to remote employees and also they provide some limited network access to business partners. This greatly improves the business productivity while maintaining security. Disadvantages Network Traffic Many simultaneous VPN connections increase the network traffic and slow down the speed and reduce the bandwidth. Network Delays and disconnections Since the virtual connections are made through public network, delays and disconnections may occur. Since the authentication has to be re-established after disconnection, it incurs additional delay. Applications SSL VPN finds applications in organization where remote employees need secured access to the corporate network thus improving business productivity and reducing the communication costs. VPN design and implementation factors The factors to be considered in VPN design and implementation are: Type of VPN Remote Access or Site-to-Site or combination Application to be met time constraints, bandwidth requirement, security requirements etc.,[2] Required levels of protection Authentication, Encryption etc., Scalability of the network geographical span, cost of implementation etc., Support and Management of the network Policies and Configuration, Authentication, accounting, QOS, Routing and backup paths etc.,[8] Maintenance of the Network By contractor or ISP, cost factor etc., VPN Implementation considerations The following factors are to be considered in the implementation of Site-to-Site VPN. Access Control: The business partners are not allowed to access all the information of the company and they should have limited access. Data Confidentiality: The data should be hidden while travelling through the partners intranet. The factors to be considered in the implementation of Remote Access VPN are Data Confidentiality and authentication, addressing and routing issues and multiprotocol support. To build the optimal virtual networks across multiple domains is an essential technology to offer flexible services [12]. Conclusion This report discusses the implementation of two types of VPN Multiple business sites and Tele worker. The principle behind Virtual Private Network is explained with its types. The implementation of both networks with and without IPSec, applications, advantages and disadvantages are summarized. The security and tunneling methods of VPN are discussed. The design and implementation factors are analyzed. References A comprehensive guide to virtual private networks. IBM Corp., 1999. Cui and M. A.

Romantism Essays - Lecturers, Civil Disobedience,

Romantism And Rationalism Romanticism began in the mid-18th century and reached its height in the 19th century. The Romantic literature of the nineteenth century holds in its topics the ideals of the time period, concentrating on emotion, nature, and the expression of "nothing." The Romantic era was one that focused on the commonality of humankind and, while using emotion and nature; the poets and their works shed light on people's universal natures. Romanticism as a movement declined in the late 19th century and early 20th century with the growing dominance of Realism in the literature and the rapid advancement of science and technology. However, Romanticism was very impressionative on most individuals during its time. Rationalism or Realism was erected during the mid 19th century. Realism are ideas that are brought up in philosophical thinking. The realistic movement of the late 19th century saw authors accurately depict life and it's problems. Realists attempted to give a comprehensive picture of modern life by presenting the entire picture. They did not try to give one view of life but instead attempted to show the different classes, manners, and stratification of life. The Rationalist recognizes that they must master their own destiny, using their unique powers of reason and the scientific method to solve problems. Such authors that represent these two eras are Ralph Waldo Emerson, Henry David Thoreau, William Wordsworth and Charles Darwin. Romantics believed that one needed to understand nature to understand oneself. In other words, only through nature could one discover who they are. Emerson shows this in his writing called "Nature". In the exert "...man beholds somewhat as beautiful as his own nature." This depicts Emerson's feelings toward nature; view nature as you view yourself. If one views nature as caring and compassionate, one will also see themselves as caring and compassionate. Similarly if you understand nature you will know yourself better. As one gains wisdom from nature, one begins to realize that understanding is a gate way to the divine as well as to oneself. Other writers also agreed with this notion of nature. In the essay "Walden" by Thoreau, Thoreau had left society to move into a shelter outside of his town. By living on only the necessities he lived his life as simple as he could, thus finding the divine within himself. By being separate from society and being one with yourself are the only ways one can find the divine. Thoreau felt by doing this society would have a harder time to mold him into what it wanted him to think. Thoreau left a life of luxury for "voluntary poverty". Even though he was "poorer in his outward riches" he was wealthy in his "inward riches". A good number of romantic views of Nature suggested using Nature as ones tool to learn. This is evident in William Wordsworth's poem "The Tables Turned. In the poem "The Tables Turned" Wordsworth states to "quit your books [for it is] a dull and endless strife[;] enough of Science; close up those barren leaves." Wordsworth believed piece that books were useless to learn from. He believed that we should "Let Nature be [our] Teacher [for it]...may teach you more of man [and] moral good and evil[, more] than all the sages can." Wordsworth agreed with the previous notion that to understand the divine and oneself, they must first start with understanding Nature. This View of studying Nature is taken one step further by Charles Darwin. Perhaps the most appealing quality of Darwin's work was that it accounted for phenomenon in a purely naturalistic manner. It was the most scientific explanation yet, completely removing the supernatural explanation, and setting him apart from the theorists before him. The major unsettled scientific question of Darwin's Theory was be in regards to natural selection as the mechanism for change, which became the issue among the general public as well. It took several years for the idea of natural selection to become accepted within the scientific community. Darwin's work was not immediately accepted as science. In a sense, he was revolutionary, not just for proposing an explanation of evolution that removed the supernatural element, but also for the fact that he was able to present his ideas to the scientific community in an unconventional manner, through speculative thought. The essential idea in Darwinian evolutionary thought is that species are not immutable. The prevailing assumption prior to Darwin was that species were immutable ( i.e. fixed in their characteristics). This idea was held in opposition to the evidence that humans had been doing selective breeding on cattle, horses, birds, fruit Romantism Essays - Lecturers, Civil Disobedience, Romantism And Rationalism Romanticism began in the mid-18th century and reached its height in the 19th century.
