Packet Sniffing Software Is A Controversial Subject Information Technology Essay

Packet Sniffing Software Is A Controversial Subject Information Technology Essay Packet sniffing software is a controversial subject and a double-edged sword. It can be used to analyze network problems and detect Internet misuse. But at the same time, it allows hackers and people with malicious intention to sniff out your password, get your personal information, and invade your privacy. That is also why securing and encrypting data is so important. In this paper, the definition of packet sniffing will be introduced and several functionality and possible uses of packet sniffers will be explained. Also, information on how to protect against sniffers and man-in-the-middle attacks will be provided. An example of a packet sniffer program, Wireshark, will be given, followed by a case study involving the restaurant chain Dave Busters, which will show the negative consequences that can occur when organizations are not aware of the threat of packet sniffing by hackers. Definitions A packet sniffer is a computer program or a piece of computer hardware that can intercept and log traffic passing over a digital network or part of a network (Connolly, 2003). Packet sniffers are known by alternate names including network analyzer, protocol analyzer or sniffer, or for particular types of networks, an Ethernet sniffer or wireless sniffer (Connolly, 2003). As binary data travels through a network, the packet sniffer captures the data and provides the user an idea of what is happening in the network by allowing a view of the packet-by-packet data (Shimonski, 2002). Additionally, sniffers can also be used to steal information from a network (Whitman and Mattord, 2008). Legitimate and illegitimate usage will be explained in later sections. Packet sniffing programs can be used to perform man-in-the-middle attacks (MITM). This type of attack occurs when an attacker monitors network packets, modifies them, and inserts them back to the network (Whitman, et al., 2008). For example, a MITM attack could occur when two employees are communicating by email. An attacker could intercept and alter the email correspondence between each employee, without either knowing that the emails had been changed. MITM attacks have the potential to be a considerable threat to any individual or organization since such an attack compromises the integrity of data while in transmission. Packet sniffing programs work by capturing binary data that is passing through the network, and then the program decodes the data into a human-readable form.   A following step called protocol analysis makes it even easier for the data to be read.   The degree of these analyses varies by individual packet sniffing program. Simple programs may only break down the information in the packet, while more complicated ones can provide more detailed information and analysis, for example, by highlighting certain types of data such as passwords that pass through the network (Packet Sniffing, Surasoft.com, 2011). As for todays networks, switch technology is commonly used in network design. This technology makes it increasingly easy to set up sniffing programs on servers and routers, through which much traffic flows. In addition, there are already built-in sniffing modules being used in todays networks. For example, most hubs support a standard called Remote Network Monitoring (RMON). This kind of standard allows hackers to sniff remotely with the SNMP (Simple Network Management Protocol), used in most network devices, and only requires weak authentication. Network associates Distributed Sniffer Servers are used by many corporations. These servers are set up with passwords that are quite easy to guess or crack. In addition, computers with Windows NT system usually come with Network monitoring agent, which also allows remote sniffing (Packet Sniffing, ISS.net, 2011). Essentially, these sniffing programs are set up for the use of network administrators. However, the threat exists that hackers ca n gain access to the network and view the program logs. Packet sniffers capture all of the packets that travel through the point where the sniffer is located.   For example, if the program was installed next to the server of an organization, the user could have access to all the data being transferred across the company through that server.   Typical types of packets intercepted by attackers include the following: SMTP (email): The attacker can intercept unencrypted emails (Packet Sniffing, ISS.net, 2011). HTTP (web): Web traffic information and history can be easily captured (Packet Sniffing, ISS.net, 2011). Telnet Authentication: Login information to a Telnet account can be intercepted (Packet Sniffing, ISS.net, 2011). FTP traffic: Access to an FTP account can be sniffed in cleartext (Packet Sniffing, ISS.net, 2011). SQL database: Information from web databases is also vulnerable (Packet Sniffing, ISS.net, 2011). Functionality and Possible Uses of Packet Sniffers Good and Bad Uses Like any tool, a packet sniffer is a double-edged sword because it can be used for good or bad purposes (Orebaugh, Ramirez, and Beale, 2007). It can be used by security professionals to investigate and diagnose network problems and monitor network activity (Orebaugh, et al., 2007). Conversely, it can be used to eavesdrop on network traffic by hackers, criminals, and the like, who can use the data gathered for harmful purposes (Orebaugh, et al., 2007). Professionals such as system administrators, network engineers, security engineers, system operators, and programmers use packet sniffers for a variety of uses, including troubleshooting network problems, figuring out system configuration issues, analyzing network performance (including usage and bottlenecks), debugging during the development stages of network programming, analyzing operations and diagnosing problems with applications, and ensuring compliance with company computer usage policies (Orebaugh, et al., 2007). Good: Troubleshoot Network Problems When an error occurs on a network or within an application, it can be very difficult for administrators to determine what exactly went wrong and how to correct the error. Many consider the packet sniffer to be the best tool for figuring out what is wrong with programs on a network (Neville-Neil, 2010). Examining packets as a starting point for solving problems is useful because a packet is the most basic piece of data and holds information, including the protocol being used and source and destination address (Banerjee, Vashishtha, and Saxena, 2010). Basically, at the packet level of analysis, nothing is hidden when all layers are visible (Neville-Neil, 2010). Understanding the timing of what happened is another important factor in debugging network problems (Neville-Neil, 2010). This information can be easily attained by using a packet sniffing program. Essentially, packet sniffers allow you to find out the who, what, and when of a situation, all of which are vital to understanding how to fix a problem (Neville-Neil, 2010). Once these things are known, the administrator can determine what is causing the problem and how to go about fixing it. As soon as a problem occurs, the first recommended step is for the network administrator to use a packet sniffing program to record all network traffic and wait for the bug to occur again (Neville-Neil, 2010). If the administrator already had a packet sniffing program with logging in place, then he or she could go back and examine the log records. Assuming the administrator did not have a log previously set up, the next step would be to only record as much information as necessary to repair the problem (Neville-Neil, 2010). It would not be a good idea to record every single packet of data because if too much data is collected, finding the error will be like finding a needle in a haystack although the administrator has likely never seen a haystack that big (Neville-Neil, 2010). For example, recording only one hour of Ethernet traffic on a LAN will capture a few hundred million packets, which will be too large to sort through (Neville-Neil, 2010). It goes without saying that the admini strator should not record the data on a network file system because the packet sniffer will capture itself (Neville-Neil, 2010). Once the data is recorded, the administrator can examine the packets to analyze and understand what occurred to solve the problem. Good: Network Optimization In addition to solving network communication problems, packet sniffers can help administrators plan network capacity and perform network optimization (Shimonski, 2002). A packet sniffer allows users to view data that travels over a network packet by packet (Shimonski, 2002). However, rather than having to examine each packet, the appropriate sniffer program will perform the analysis for the administrator. The tools are especially useful because depending on the packet sniffing program used, the packet data will appear in an easy-to-understand format. Packet sniffers can often generate and display statistics and analyze patterns of network activity (Shimonski, 2002). Data can appear in graphs and charts that make analysis and comprehension easy. Additionally, the network administrator can filter by selected criteria to capture only the relevant traffic rather than having to sort through irrelevant data (Shimonski, 2002). Knowing what programs and which users use the most bandwidth can help administrators manage resources efficiently and avoid bandwidth bottlenecks. Good: Detect Network Misuse Packet sniffers can be used to monitor application traffic and user behavior (Dubie, 2008). This can be used to detect misuse by company employees or by intruders. To use a packet sniffer to monitor employees legally, a network administrator must do three things. First, he must be on a network owned by the organization, second, he must be directly authorized by the networks owners, and finally, he must receive permission of those who created the content (Whitman, et al., 2008). Permission by content creators is needed because packet sniffing is a method of employee monitoring (Whitman, et al., 2008). Typically, an employee will sign a release form when first employed that allows the employer to monitor the employees computer usage. By using a packet sniffer, employers can find out exactly how each employee has been spending his or her time. Packet sniffers can be used to see all activity and administrators can monitor for behaviors such as viewing inappropriate websites, spending time on the job on personal matters, or abusing company resources. For example, a packet sniffer program could show that a particular employee was downloading music at work, both violating organizational policies and using a large amount of network bandwidth (Dubie, 2008). Packet sniffers are also used to detect network intrusion, log traffic for forensics and evidence, discover the source of attacks such as viruses or denial of service attacks, detect spyware, and detect compromised computers (Orebaugh, et al., 2007). A packet sniffer and logger that can detect malicious entries in a network is a form of an intrusion detection system (IDS) (Banerjee, et al., 2010). The packet sniffer IDS consists of a database of known attack signatures. It will then compare the signatures in the database to the logged information to see if a close match between the signature and recent behavior has occurred. If it has, then the IDS can send out an alert to the network administrator (Banerjee, et al., 2010). Despite this use of packet sniffers to detect intrusion, hackers have methods of making themselves very hard to detect and can use packet sniffers for their own advantages. Bad: Gain Information for Intrusion Intruders maliciously and illegally use sniffers on networks for an innumerable number of things. Some of the most common are to capture cleartext usernames and passwords, discover usage patterns of users, compromise confidential or proprietary information, capture voice over IP (VoIP) telephone conversations, map out a networks layout, and fingerprint an operating system (Orebaugh, et al., 2007). The previously listed uses are illegal unless the user is a penetration tester hired to detect such types of weaknesses (Orebaugh, et al., 2007). An intruder must first gain entry to the communication cable in order to begin sniffing (Orebaugh, et al., 2006). This means that he must be on the same shared network segment or tap into a cable along the path of communication (Orebaugh, et al., 2007). This can be done in many ways. Firstly, the intruder can be physically on-site at the target system or communications access point (Orebaugh, et al., 2007). If this is not the case, the intruder can access the system in a variety of ways. These include breaking into a certain computer and installing sniffing software that will be controlled remotely, breaking into an access point such as an Internet Service Provider (ISP) and installing sniffing software there, using sniffing software that is already installed on a system at the ISP, using social engineering to gain physical access to install the software, working with an inside accomplice to gain access, and redirecting or copying communications to take a path that the intruders comp uter is on (Orebaugh, et al., 2007). Intruders can use sniffing programs designed to detect certain things such as passwords and then use other programs to have this data automatically sent to themselves (Orebaugh, et al., 2007). Protocols that are especially vulnerable to such intrusion include Telnet, File Transfer Protocol (FTP), Post Office Protocol version 3 (POP3), Internet Message Access Protocol (IMAP), Simple Mail Transfer Program (SMTP), Hypertext Transfer Protocol (HTTP), Remote Login (rlogin), and Simple Network Management Protocol (SNMP) (Orebaugh, et al., 2007). Once the intruder has access to the network, he can collect data and use it as he likes. Common examples of stolen data include credit card numbers and proprietary organizational secrets, but include anything the hacker desires. Although organizations may use a primarily switched network, they are not protected from sniffer attacks because many programs exist that allow packet sniffing in a switched network (Whitman, et al., 2008). Because intruders who use packet sniffers do not directly interface or connect to other systems on the network, they are considered to be a passive-type of attack (Orebaugh, et al., 2007). It is this passive nature that makes sniffers so difficult to detect (Orebaugh, et al., 2007). In addition to this, hackers use normally use rootkits to cover their tracks so that their intrusion will not be detected (Orebaugh, et al., 2007). A rootkit is a collection of Trojan programs hackers use to replace the legitimate programs on a system so that their intrusion will not be detected (Orebaugh, et al., 2007). Rootkits replace commands and utilities that the hacker inputs and clears log entries so that there will be no record of his entry (Orebaugh, et al., 2007). Though it is difficult, there are some ways to detect rootkits. Methods of detection include using an alternate, trusted operating system, analyzing normal behaviors, scanning signatures, and analyzing memory dumps (Rootkit, Wikipedia , 2011). Removing rootkits can be very complicated and difficult and if the rootkit is in the central operating system, reinstalling the operating system may be the only option (Rootkit, Wikipedia, 2011). The threat of eavesdropping by intruders is large and challenging. However, there are some defenses that can be taken to prevent hackers from using packet sniffers against an organization. Protecting Against Packet-Sniffers and Man-in-the-Middle Attacks Packet sniffing and man-in-the-middle attacks compromise the integrity and confidentiality of data while in transmission.   Fortunately, there are several techniques that can be used by organizations and individuals to protect against these threats and reduce risk.   Specifically, technology, policy, and education are typically used to cover all aspects of security.    Technology Encryption is the best form of protection against any kind of packet interception (Orebaugh, et al., 2007).   The reason behind this is that even if the data is captured by the packet sniffer, the information is completely unreadable by the attacker (Orebaugh, et al., 2007). By using this technique, messages are encrypted once the data leaves the senders computer.   Both sender and receiver hold a key that decrypts the message being transferred.   Most popular websites apply a level encryption by using the HTTP Secure (HTTPS) protocol.   With this technology, the connection between the web server and the users computer is encrypted; making the information intercepted by a third party useless.   Currently, most popular websites such as Google, Facebook, Yahoo, and Twitter use the https technology.   However, some sites (such as Amazon.com) use https only at the login page and fail to provide a secure connection afterwards.   In order to assure complete security, it is im portant to apply the https protocol throughout the users browsing experience.   The main disadvantage of this feature is that it slightly slows down the users connection.    Email can also be protected from packet sniffers by using encryption.   Email extensions such as Pretty Good Protection (PGP) can be easily implemented using standard email platforms like Microsoft Outlook (Orebaugh, et al., 2007).   Once sender and receiver start using the encryption techniques, intercepted email messages cannot be interpreted by an attacker (Orebaugh, et al., 2007). Another way to protect against sniffers is by using One Time Passwords (OTP). With this method, a different password is sent every time the authentication is requested to the user (Orebaugh, et al., 2007).   Similarly to the case of encryption, if a third party intercepts someones password, this information will be useless since these can only be used once (Orebaugh, et al., 2007).   This technology can be extremely useful to ensure security; however, remembering new passwords for each login can be very challenging and frustrating for most users. A new security technique called quantum encryption is also provides good protection against sniffing attacks.   This technique consists of making each bit of data as small as a photon (McDougall, 2006).   The data is then transferred across fiber-optic lines.   Ã‚  If the information is picked up and intercepted by any kind of packet sniffer, the entire photon message is disrupted, ending up the entire transmission (McDougall, 2006).   A technology like this would make it impossible to intercept information since the communication will be cut in the case of interception.   However, it requires fiber-optic Internet connections, which many service providers do not own and its installation can be expensive. Policy Information security professionals can help secure employees connections by requiring the use of any of the technologies explained before.   For example, if certain employees need to access websites that are outside of the organizations network, they should be allowed to use only websites that use the https protocol such as Google and Yahoo.   Policies requiring Access Control Lists (ACL) can also help prevent sniffer attacks.   All secured networks and assets should be supported by an ACL to prevent unauthorized access.   Additionally, physical security policies should be implemented to efficiently protect the computer and server rooms in the organization.   Unauthorized access to these locations could cause the installation of sniffer programs and equipment. Education Every security initiative should have a training program supporting it.   Basic but regular training sessions given to employees about the dangers of packet sniffing can prove to be very valuable when protecting a network.   Security facts such as not allowing strangers to computer rooms should be explained to all employees. Example and Demonstration of a Packer-Sniffer Program: Wireshark Originally named Ethereal, Wireshark is a free and open-source packet analyzer (sniffer) typically used by network and security professionals for troubleshooting and analysis (Orebaugh, et al., 2007).   However, many potential attackers also use it to perform man-in-the middle attacks and gain information for password cracking.   Wireshark is available for most operating systems (including OS X, Windows, and Linux) and allows users to see all the traffic that goes through a specific network (Orebaugh, et al., 2007). Wireshark differs from other packet-sniffer programs mainly because of its easy-to-understand format and simple Graphical User Interface (GUI) (Orebaugh, et al., 2007).   Wireshark can be easily set up to capture packets from a specific channel.   Once the program is running, all the network packets are shown in the screen.   The top panel (summary panel) shows a summary of the entire packet, including source, destination, and protocol information (Orebaugh, et al., 2007).   Since one quick web browse can provide a large amount of packets, Wireshark solves packet browsing issues by categorizing each packet according to its type and showing each category with a specific color in the GUI.   Additionally, the user has the option of applying filters to see only one type of packets.   For example, only packets dealing with http functions may be shown.   The middle panel in the GUI is called the protocol-tree window. It provides decoded information of the packet (Orebaugh, et al., 2007). Finally, the bottom panel (data view window) shows the raw data of the packet selected in the Summary panel (Orebaugh, et al., 2007).   Figure 1 shows a screenshot of Wireshark while running and graphically shows the three main panels of the GUI. Figure 1 Screenshot of Wireshark while running and the three main panels. To troubleshoot network problems, Information Systems professionals use Wireshark by installing the sniffer program in various locations in the network and seeing which protocols are being run in each location (Orebaugh, et al., 2007).   Additionally, if the sniffer is placed in a location where it can capture all data flowing to the main server, Wireshark can detect network misuse by providing the source and destination of all packets.   For example, if an employee in a company uses his computer to access inappropriate websites, Wireshark will show the employees and the websites IP addresses in the source and destination columns with detailed information about the website in the info column and the protocol tree panel. It is easy to see how useful Wireshark is for network troubleshooting and identifying misuse; however, the program can also be used with malicious intent.   For example, the program can be used to find out passwords on unencrypted websites.   To demonstrate this case, the username john_doe_user and password 123mypasswrd were used to log in to the unencrypted and unsecured www.bit.ly website.   At the same time, Wireshark was set up to capture all packets in the computer.   After the packets were captured by the sniffer, the data can easily be filtered by the http category.   In the info column, a packet labeled POST means that someone has entered text to a website.   After clicking on this specific packet, all the username and password information can be seen in the center section of Wireshark (as shown in figure 2).   Unencrypted and unsecured websites are very vulnerable to these types of attacks.   On the other hand, websites using the https security feature prove to be safer for users.   For example, the same situation as before was applied to the encrypted website www.facebook.com by trying to log in, but Wireshark was unable to capture any packets with login information. Figure 2 Wireshark screenshot showing username and password. Other types of malicious attacks can also be performed with Wireshark.   For example, some toolkit add-ins to Wireshark such as Dsniff and Ettercap can be used to perform man-in-the-middle attacks and password cracking (Orebaugh, et al., 2007).   Even if the incoming data is encrypted, these tools can crack some passwords by using dictionary brute force attacks (Orebaugh, et al., 2007). Case Study: A costly attack at Dave Busters In 2007, the popular restaurant chain Dave Busters experienced the power of malicious packet-sniffing software attacks.   A multinational group of hackers was able to penetrate the companys corporate network and install basic packet-sniffing software at 11 of the chains restaurant locations (Thibodeau, 2008).   During a four-month period, the attackers were able to intercept customer credit card data going from Dave Busters restaurant locations to the corporate headquarters network in Dallas (McMillan. 2008).   Extremely sensitive information such as credit card numbers and security codes were sold to criminals, who used this data to perform fraudulent transactions to online merchants (McMillan, 2008).   The attack proved to be very profitable for the hackers.   For example, from information coming from only one restaurant location, the criminals were able to gain over $600,000 in profits (McMillan, 2008).   It was estimated that approximately 130,000 credit or debit ca rds were compromised by this attack (Westermeier, 2010). To access Dave Busters network, the attackers simply drove around a restaurant location with a laptop computer and took advantage of vulnerable wireless signals to access the computer networks (Westermeier, 2010).   Malicious sniffing software was then installed in the network to intercept credit and debit card information (Westermeier, 2010).   The packet-sniffing software was written by one of the groups hackers and consisted of SQL injection attacks (Thibodeau, 2008).   However, many organizations have stated that the code was not very impressive.   For example, the CERT Coordination Center described the programs source code as a college-level piece of technology (Thibodeau, 2008).   Additionally, the malicious code had one weakness: it would shut down every time the computer that was monitoring rebooted (McMillan, 2008).   Therefore, the criminals had to go back to the restaurant location, gain access, and re-start the packet-sniffer every time this happened. The fac t that this costly program was developed by someone with just basic programming skills and how they consistently gained access to the network highlights the lack of protection of Dave Busters security systems.    According to the Federal Trade Commission (FTC), Dave Busters information security systems and policies did not provide the necessary security features to protect customers information (Westermeier, 2010).   The attackers were able to access the network not just once, but repeatedly over a time frame of four months (Westermeier, 2010).   The fact that the company was oblivious to these multiple intrusions during a long time period proves that they were vulnerable to attacks and that Dave Busters did not apply any Intrusion Detection Systems (IDS) to their networks, nor did they monitor outbound traffic (Westermeier, 2010).   Additionally, sensitive customer information was not given special protection.   Credit card data was transferred across simple unprotected and unencrypted networks (Westermeier, 2010).    What could Dave Busters have done? First of all, private networks should have been protected in a better way.   It was just too easy for hackers to gain access and install malware.   By allowing only a specific group of IP addresses, or granting only temporary access, the firm could have been safe from unauthorized access by strangers.   But even in the case of hacker access, tools such as IDS can help monitor the network during an attack.   If the company had implemented an IDS in their network, the unauthorized intruders would have been detected in time to prevent losses. Additionally, by treating sensitive data differently than regular communications, the company could have considerably reduced the threat.   Dave Busters could have simply used readily available firewall systems to the networks that held customer data (Westermeier, 2010). Encryption devices could have also proven to be useful.   If link encryptors had been used, the intercepted data would have been completely useless for the hackers.   Data isolation could have also been useful.   The firm could have separated the payment card systems from the rest of the corporate network (Westermeier, 2010). Sensitive information did not necessarily require connection to the Internet; so the company should have separated these transmissions from the network. Finally, a general company-wide policy requiring access restriction, IDS installation, firewall usage, and sensitive data isolation throughout all restaurant locations could have been extremely useful.   A uniform and thorough information security policy along with a comprehensive training program given to specific employees would help enforce the security features.   Considering that Dave Busters had not implemented any of the security features explained in this section, it is obvious that their story would have been different if these techniques had been used. Conclusion Packet sniffing is a sophisticated subject that wears two hats. It can be used for either good or evil depending on the intentions of the person using the program. It can help with analyzing network problems and detect misuses in the network for good purposes. Meanwhile, it can also help hackers and other cyber-criminals steal data from insecure networks and commit crimes, as in the case of Dave Busters. The best way to protect data from being sniffed is to encrypt it. Necessary policies and training also help with the protection. As technology evolves, there will be more and more ways to commit cyber crime. Extremely sensitive data like credit card information and health care data should be well protected, from the perspectives of both the business and personal. In order to protect this information, organizations and individuals must be aware of the threat of packet sniffers.

Education of Shelby Knox Essay

The education of Shelby Knox was a complete mind-blower for me. The video follows young Shelby Knox, from Lubbock, Texas, as she aspires to get sex education into schools in Lubbock. This town preaches abstinence, and the town’s people appear to be incredibly ignorant. Ignorant may be an understatement . The teen pregnancy rates here are twice the national average, as are the sexual transmitted disease rates. They don’t believe in teaching sex education because the town’s people believe very strongly in the idea that sex isn’t permitted until marriage. Shelby’s fight goes for naught as the town holds their ground. The video also shows Shelby’s unique relationship with her parent’s, and the resistance they even have with her and her fight for sex education in schools. The film also touches on gays and their fight for equal rights within the schools. Lubbock , Texas is a place I would never like to visit. The people there seem to be living in the 1800’s still. Shelby and the youth commission were fighting for a very good cause. Sex education is very important. It can teach the rewards, dangers, and consequences of having sex. As the old saying goes, knowledge is strength. If these kids don’t have the knowledge, how can they ever be expected to make smart decisions? Based on the bible and their commitment to the church? It is absolutely ridiculous that religion is even mentioned when this topic comes up. The town, as mentioned above, has earned twice the national average for teen pregnancy and std rates. The church angle clearly isn’t working. I agree with Shelby’s fight, it is very courageous of her. I disagree with the towns council, the residents , and the school boards stance on the issue. I do believe this film covered all perspectives and issues at hand. No, Shelby Knox’s fight didn’t turn out the way one would have hoped, but it did enlighten every viewer to the fact that Lubbock, Texas and the vast majority of their residents are incredibly naiive. I do not like the religious views, on the subject, shared by the vast majority of the people in this film. Religion should not even be mentioned when the issue of sex education in public schools comes up. Shelby maybe should have spoke up on that issue a little more. Coming from a family that has never preached religion, I never really realized how crazy some people can be over t. It all makes no sense to me. The video was about sex education. Religion has to be tied into it for whatever reason. I don’t understand the downside to teaching our countries teenagers the dangers and consequences of sex. It is in our nature to have sex. Suppressing teenagers from knowledge and their sexual urges based on religion is a complete joke. I learned that religion shouldn’t even be mentioned when it comes to such issues. I also learned that Mr. Ainsworth is a crazy person, and I need to keep my future kids as far away from that guy as possible. The society we live in today needs to wake up, and stop basing important decisions on religious beliefs. This video ties directly into all of our course material. Sex is a huge part of life, for all of us, beginning with puberty. America’s teenagers need to be educated on every aspect of sex and its consequences. As std rates, teen pregnancy rates and overall teenage sex rates continue to climb, it is more important than ever to educate them. This class, Psych 240, should literally be installed into every high school across the country. Teaching about every aspect of sex can only be beneficial to our country.

How effective an adaptation of the play Macbeth is the film ‘Macbeth on the Estate’?

Macbeth on the Estate is a modern adaptation of Macbeth. It is set on a modern, run-down housing estate in Birmingham. The major changes from the play are the setting and the characters. There are much fewer noble qualities about the people and places shown. Instead, the setting is very run-down and poor. The characters are also corrupt and indulgent. A lot of the blame for the bad things that happen in the play seems to be given to characters. For example, the possibility that the witches control Macbeth, and he is not in control is implied to be untrue by suggesting that the effects that seem to be supernatural are simply caused by drugs and the poor conditions. There are also some things done that cannot be done in a theatre, such as camerawork to direct the audience. I believe that the film is a reasonable good conversion of the play into a modern film. I believe that it managed to portray the meaning of the original in a modern way that is easy to understand for modern people, as well as making suggestions about the story. I like how every aspect of Shakespearean world was converted into something of the modern world, for example the castle being converted into a social club. What I don't like about it is the fact that the language wasn't changed from the original text. Although it is quite important to keep the film similar to the original, so as not to forget that it is the same play, I think it made the film too much like the original play. I believe that if the setting is changed, the modernisation should be completed by making the language more modern. The point of the film is, after all, to give a modern slant. The language is the most out-of-date part and the most difficult-to-understand part of the play, and I believe that modern language should have been included. I will answer the question of how the ideas have been modernised mainly by giving various examples and explanation of what has been shown in their modernisation. I will answer the question of how the beginning and ending of the play have been changed by describing both beginnings and endings, explaining the changes made and also by giving reasons for changes. I will discuss the change in theatricality by first describing the differences between what can be done in film compared with theatre, and then describing and explaining the particular changes. I will discuss the characters by giving a description of the general change in the characters, and why this is, and then by analysing the change in each character individually, with possible reasons for these changes. I will then discuss how and why the adaptation loses its social and historical meaning and adds a meaning of its own. Shakespeare plays are often modernised to make them more accessible to modern people. This is so that people now can understand the plays, and can understand the meanings behind the plays, because they have been put into a modern context that we can relate to. Some ideas are not actually just translated; they are completed changed, or some are added. For example, the idea of Macbeth being totally evil is changed. Because this modernisation is a film, which means that it has certain ways to direct the audience in a certain way, a select few of the ideas from the original play are translated. An example of these is the idea that Macduff is a complete hero. Although I do not like the fact that only a few ideas are translated, I believe that on the whole, the few that have been translated have been translated well. The beginning and ending of a play or film can be very important for the meaning behind it. Beginnings give the audience a place to start from, to understand the story. They introduce the story and characters, and give the producers a place to start the story from. Endings are useful to round off the story, and give the producers a place to end the story. They are also useful to round off the story for the audience, whether it is a resolved ending or a cliffhanger. The very beginning scene of the play involves the three witches discussing Macbeth. This gives and impression of them controlling the plot, and makes this scene seem like the original source of Macbeth's evil. The beginning of the film is very different to that of the play. Macduff says an invented dialogue, although the audience does not know who he is at the time. The beginning has a lot of subtle references to the setting and the meanings. Macduff recites the new speech on a large wasteland. When the camera first shows this setting, before Macduff enters the scene, there is nothing restricting the view, and the whole of the frame is used, including the very extremities, so there is no particular focus point. This makes suggestions about the idea of confusion and the lack of focus in the story. The fact that the camera fades in re-enforces this with a feeling of fog. This barren landscape could be a battlefield, possibly like one in the play, reflecting the war-like culture. The fact that we don't know what it is re-enforces the idea of confusion, and also the idea about the audience deciding themselves about the true meaning of the play. The shot of Macduff is very close to him, and he looks right into the camera. This gives the impression that he is talking directly to the audience. This and the fact that Macduff is in the very first scene, rather than the witches, give an impression that Macduff is controlling the whole story, instead of the supernatural. I believe that Macduff is used as part of the way that the director makes him a larger part of the story, to ask questions about his true character. There are many differences between a play and a film. The main one is that with a play, the audience can interact much more, and can decide the story for themselves. This mainly comes from lack of direction, and the ability to imagine elements of the story. One way in which this is done is by not directing the audience's view. In a film, because there is a camera, the audience's view can be directed onto a particular character or object. This means that the audience's view can also be sub-consciously directed towards a particular meaning to the film. In a play, on the other hand, the audience is free to look at whichever characters they wish, to watch their actions and reactions to other events. This adds an element of the audience being able to decide what really happens in the play, and being able to decide which ideas are true, as well as the director being able to direct the audience to parts which show their own feelings. Another way in which is this is achieved is the difference in how the setting is portrayed. A film can be shot in different locations, making the setting much more believable, and making it seem much more like the characters are in the place where they are supposed to be. One again, this allows the audience to be directed, and shown exactly what the director believes the setting is, leaving no room for imagining it. A play has a much less vivid, defined setting. It is demonstrated by symbolic references to the actual things, meaning that the audience has to imagine them more. This means that a film is better if the director wants to deliberately highlight a particular idea to the audience, and wants to tell them something that they believe in. A play is better for giving a more open story, in which the audience is independent, and decides what is true about the story. Although the setting and characters are updated in the film, the language is not. As I have already mentioned, personally, I do not believe that this is very effective, because I think that if some parts are modernised, all the parts should be, although it is quite important to keep the conversion similar to the original. Tension can be shown very well in film, by using particular camera angles or special effects. This means that the tension in the film is shown much better, which is good, but only some elements of tension are properly shown, because the director has chosen to use only certain ideas. Because of the differences between film and theatre, the audience can also be directed towards certain elements of tension. In film, visual images can be used very well, because it is a visual medium, by using special effects. I do not believe that visual effects are used to a great extent in Macbeth on the Estate. The images used are not particularly used much more than they would be in a play. I do not believe that the potential for visual effects is used fully. Instead, the film loses some of the quality of the language from the play, which is an oral medium, making the film a less effective adaptation. It may be true, though, that the director has chosen to do this because what she wants to tell us is done much more subtly by using changes in the characters and setting. The soliloquies in the film are not adapted from the play very much. No elements that are exclusive to film are used, such as visual effects, making the soliloquies very similar to the originals. This is again because the director only wanted to make subtle changes. The actor can change their character by showing different body language, for example facial expression, and can use different tones to change the meaning of what the character is saying. The way that an actor can change the character is subtle, by changing subtle things not mentioned in the script. The part can be changed in many different ways. Some of these are quite significant, such as changing the original lines, adding soliloquies and changing things that are described directly in the original script. Others are less significant, and only involve changing parts that are not directly expressed in the original script, for example set locations and body language for the actors to use to help slightly change the emotions and related things, which make up the characters. The main alteration to the characters was to make them seem corrupt and not noble, to put them and society partly to blame for everything. It is mainly the characters that are very noble in the play who are changed, to make them seem less so. The major of these is King Duncan. In the play, he was known as a good and much-loved king. In the film, although he is liked a lot by the main characters, he has lost his nobility and kingliness. Instead of his castle, he has a social club, and he is very indulgent. Although all of the characters drink and smoke, he does these to more extent, and he almost never seen without a pint of beer. As well as having un-noble habits, he is also quite a sleazy character. For example, he hassles Lady Macbeth and is unpleasant to some of his servants. He is the main element in the way that the new director shows the environment around Macbeth as being corrupt and his character is changed more extremely than the others, in this way, because he is seen as the figurehead of the nobility in the play, being the most noble. Duncan's son, Malcolm, seems to be changed to also reflect the corrupt environment, but not as much. As in the play, he does what his father does, and copies him, but this is different in the film. He joins in with the indulgence, but this could just be the result of the world around him. Like in the play, he is quite good-natured, and a good person. The director could have used this to make suggestions about young people, not just now, but always, compared to adults. I believe that the fact that she shows the young people joining in with what the adults are doing, implies that they copy what the people around them do, and they quickly become just like the rest of society. The fact that he is a good person, and is not like his father suggests that people are born good and not corrupt, though, and are not like their environment until it indoctrinates them, and it becomes normality to them. This is one of the suggestions that the director makes about society that is true about today and Shakespeare's day. Donaldbain rarely appears in the film, and he is only slightly changed, in the same way as Malcolm. Banquo is changed much in the same way as the other people around the royalty; he has also lost nobility and is part of the corrupt society. Fleance remains more or less the same as in the play, but he has more of an element of innocence. He is younger than he seems to be in the film, and he has a very close relationship with his father, relying on him heavily. He seems to be very distressed by the events in the story, and there is strange thing at the end of the film: he points his hand at the camera as if it is a gun, and fires. This could be to show that he has been indoctrinated by the corrupt society, and he is no longer fearful of firing a gun, and killing someone, because Macduff shot Macbeth. I think that he could symbolise the pure good in the story which struggles to survive in the terrible environment, and then in the end has to give up and be lost into the corruption. Macduff is changed the most in relation to the other characters. In the play, he is Scottish, like most of the other characters, meaning that his background does not make him stand out from the others. On the other hand, in the film, all of the other characters are changed into English people from Birmingham. He, on the contrary, is from the West Indies, and so stands out from the other characters due to his background. This is to make him more obviously a very significant character in the story. The director has done this because she wants to portray Macduff as more of a main character than in the film, and wants to ask us about whether or not he is really as heroic as he is shown as in the play. This was because the film explores the good and evil in all of the characters more than in the play. In the play, Macduff was very blatantly shown as a purely good character, though in the film, we are made to question ourselves about whether Macduff is really as honourable as he might seem. The director probably did this because she wanted to show that there can be evil in everyone, and no one is either pure good or pure evil. Making Macduff stand out more helps illuminate what she wanted to convey to the audience. Lady Macduff is one of the characters who has been changed relatively little: in the play, she is quite a good person, and does not have too much character that is shown; also in the film she has little character shown, other than her kindness and motherliness. Although she joins in with the corrupt society a bit, she only does to moderation, and seems quite innocent. I believe that this was because the director did not want to dilute her messages, and the characters that could not help her portray her messages and did not have much significance were kept quite bland, so as not to take away the focal point from the more important characters. The innocence may have slightly helped a suggestion of feminism. The three witches are changed a lot from the film: they have become three children. I believe that the director chose to do this to help her argument about the corrupt society; she implies that they may not really have any powers, and they just cause the characters to believe in the supernatural, and so carry out the predictions themselves. This implication can be valid to show that today's society is corrupt, and may have changed since Shakespeare's time, but it could also be used to disagree with Shakespeare, and accuse the supposed supernatural occurrences of his day on the general nature of people. Lady Macbeth is one of the few characters that have had less blame put on her than in the play for the events in the story. The audience is made to feel sympathy for her, unlike in the play, which is done in a number of ways, for example by inventing something about some lost child. The changes to her are all part of the general trend that the characters' personalities are diluted into being partially good and partially bad, to make everyone, and our society, to blame for the events. I believe that the director very strongly and effectively puts across this message, and makes Lady Macbeth seem more innocent very well. This also suggests a hint of feminism. There seems to be a hint of feminism in the conversion because the female characters are shown as much more innocent that the male characters, but it is not a very strong hint. Macbeth is also relieved of some blame. In the play, he was portrayed as a thoroughly evil man, and his evil deeds were blamed solely him or the witches controlling him. He is also part of the suggestion that society creates evil, and just does what he does because of his society. The characters are mainly changed to help put across the message that the director wants to give the audience about the story. She wants to imply certain things about the individual characters, but she also uses this to give a new impression about society. Although she wants to make implications about how today's society, and how it would change the situation in the story, she may also want to make implications about timeless aspects of society that have always existed, and possibly to disagree with Shakespeare about how society was then. Although Shakespeare made a great deal of suggestions about society, I think the new director has taken the story further, and made new ones, as well as making alterations and her own touches to the original ones. Although the film seems quite bland and without many of these meanings at first, and it is difficult for the audience to realise these subtle messages when first seen, I think that she has been very successful in showing us her personal feelings about the play and in making suggestions to us about society, as long as the audience can pick them up. Any modernisation of the play inevitably results in the loss of some of its social and historical significance. This is because to understand what is meant by the play, people would need to know what the world was like at the time, and what was happening. When a play is modernised, it stops being about that world, and is about the modern world. There are a lot of modern issues in the film. Some of these are similar to those found in the original play and are only modified, and some are completely new, and are just relevant to modern life. An example of one which is only modified is the violence. The film shows that violence still exists, but in compliance with the idea of there being no nobility, the fighting is changed into dishonourable gang warfare. The modernisation is equally as much about the original play and modern society. Most of the messages behind it concern both in different ways. The best example of an idea, which complies with both, is the idea of no nobility. It works to do with the modern world because it could imply that the nobility is lost, but it could also imply that it never existed, and the people in Shakespeare's time were just as bad as now. My argument is mainly about how the director has used lots of minor alterations to tell us of her opinion of the original story. I believe that she has used the modernisation to make it easier for modern people to understand, but also as a tool to suggest that what Macbeth does is not entirely the fault of the people who were seen as completely evil before. I think she was very successful in taking Shakespeare's meanings on further, and developing new, separate ideas, as well as some contrasting with him, for example, not showing the main characters as completely good or evil, which I believe adds a very good personal touch to it, and shows very subtly, yet effectively, her personal beliefs. The main ideas I believe she wanted to put across are: nobody is completely to blame; everyone has no evil and some good; a hint of feminism; the world of Shakespeare's time exists with us today; there could be other possibilities of why the events in Macbeth happened, that Shakespeare did not include. I think that the film can be appreciated on many different levels: as a simple modernisation for easy understanding, and also as a subtly constructed message about the personal feelings of one person, which can be enjoyed by the observant audience, and can also prompt us to think about what we think about the story, and to wonder what it is really about.

Solitary Stroller And The City By Rebecca Solnit - 901 Words

Throughout the text â€Å"Solitary Stroller and the City,† author Rebecca Solnit explores the complex relationships between the walking individual and living in the city. The title brings together three central ideas; walking, the city, and solitariness as an individual.. These three central ideas are tied together and used to reveal deeper meanings and relationships within the text. When analyzing Solnit’s work, the reader is left to identify a complex relationship between the central ideas and how the geography of a city influences all the three of the central ideas. Solnit makes claims throughout the text that are strongly suggestive of a relationship between the ability to walk and its derivability based on the â€Å"when† and â€Å"where† concepts. The geography and or location can be explored through the comparison of rural walking versus urban walking, the comparison between the cities of London and New York, and the solitariness associated with the geography and structure in one city versus another. Spanning the entire text is the idea that the city influences the walker and their individualism among the crowd, or their perception of solitude. Solnit compares London walkers and New York walkers, exploring how their different geographical locations define their city as a whole as well as the individual. Geography plays a crucial role in one s idea of solitude and individualism.
