Wireshark monitor TCP/IP traffic Protocol Analysis: Capturing PacketsAssignment Wireshark monitor TCPIP traffic.pdfObjectivesThis lab will introduce you to “packet sniffing,” a method by which we can capture packets being sent between computers as they communicate. As a network administrator you can use this method to help evaluate the performance of your network by identifying bottlenecks and slower performing servers or sections of your network. You can also use it to check the security of your network. Overview & PrerequisitesYou will first install a program called Wireshark. This is an open source application freely available on the Internet that allows you to capture packets as they appear at the network adaptor card. This means that you will be able to see all header information on the packet from each of the OSI layers. (Normally these headers are stripped off so that the only portion remaining is the data payload.) You will use the software to view complete packets and locate each layer’s header, from the physical layer to the application layer. Doing so will help you to better understand network traffic and identify things that are “out of order.” Using this program you will:Analyze simple protocols and learn about the software interface and the information it contains;Observe, analyze and reconstruct specific packet interchanges between a computer and a server For this lab, you will need a single computer with an Internet connection. (Optional FTP Part is given for those who want to try it.)DirectionsTo obtain the software that you will use for this lab, go to www.wireshark.org and download it to your workstation. Once downloaded, you can install the software and accept all defaults. The program includes a helper program called WinPCap, which will install after Wireshark is installed.Part 1: Analyzing simple protocolsAfter you have installed Wireshark, start the program. The initial screen will resemble Figure 1. Notice that your local interface is listed (if you have multiple interfaces, you may see more than one entry; the names may vary). You can click the interface and press “Start” to begin packet capture. (Your interface may be different, depending upon Wireshark version.)Network InterfaceStart buttonFigure 1: Wireshark Packet Capture OptionsBelow the menu, the capture window is divided into three distinct areas. The top is a listing of all packets received—the packet list pane; the middle provides the details of a packet selected in the packet list pane and is called the packet details pane; and the bottom, called the packet bytes pane, shows the hexadecimal details of the selected packet and will highlight its (selected) fields. Figure 2 illustrates this and shows some captured packets.Packet BytesPacket DetailsPacket ListFigure 2: WiresharkYou can see in Figure 2 that multiple packets were captured and the first packet is selected in the packet list pane. In the packet details pane, you can see the Ethernet frame header, the IP header, the UDP header and finally the data payload, which indicates that this is a Bootstrap Protocol packet. The packet byte pane shows the hexadecimal and ASCII equivalent of each packet at the bottom of the window. Selecting a field in the packet details pane will highlight the hex and ASCII portions of the packet in the packet byte pane. Make a snapshot of this screen and post it in your Word document (#1).Go ahead and start a capture session and after receiving a few packets, stop the packet capture (from the Wireshark menu, select the “Capture” menu item, and choose the “Stop” command from the drop-down menu).Find a TCP packet in the packet list pane and select it. In the packet details pane, click on the “+” next to the word “Frame.” When this part of the packet opens, you will see some summary information that Wireshark logs about every packet that it captures. Now open each subsequent section of the packet beginning with “Ethernet II.” You should be able to find the portions of each packet corresponding to figures 3a through 3c within the packet details section (though the sizes of each section may not always be apparent without closer examination).Figure 3a: An Ethernet II Frame LayoutFigure 3b: The IP Header LayoutFigure 3c: The TCP Header LayoutFigure 3a includes 20 bytes that are processed in the hardware and will not be seen in the packet details pane. These are the preamble (7 bytes), the Start of Frame (1 byte), the Frame Check Sequence (FCS, 4 bytes), and the final Flag (8 bytes). Make a snapshot of this screen and post it to you Word document. (#2)Part 2: Finding specific packet sequencesFor this part you need a workstation that is connected to the Internet and one that receives its IP address from a DHCP server. (Normally you have this if you are connected to a service provider (Comcast, Verizon, etc.) You should have Wireshark installed on your workstation from part 1. In step 1 you will observe the packets required to make and break a connection.Step 1 Observing a TCP connectionEnsure that your capture options are set as before and begin another capture session. After the capture session has begun, open a web browser on your workstation, allow the web page to finish loading, and then stop the packet capture session.Look for the first three TCP packets in the packet list pane. TCP packets have a green background color (depending on your settings) and are easily recognized. These three packets should be listed as [SYN], [SYN, ACK] and [ACK]. This 3-packet interchange builds a connection between two computers. You should notice that the destination port for the [SYN] packet is 80, indicating a web request. The second two packets should provide you with a sequence/acknowledgement analysis. Make a snapshot of this screen and post it to your Word document. (#3)Step 2 Observing a DNS request/responseEnsure that your capture options are set as before and begin a fresh Wireshark capture session. You can discard the previous session or save it to a file.Begin a Command Prompt window. Next, to release the existing IP address, enter the ipconfig /release command at the command prompt. See Figure 4. (Note: if your computer has IPv6 configured, you will see the configured IPv6 address; you can release these using the ipconfig /release6 command.)Figure 4: Releasing a DHCP IP Address LeaseAs soon as you see that your IP address was released (shown as empty or 0.0.0.0, depending on your system) enter the ipconfig /renew command at the command prompt. See Figure 5.Figure 5: Renewing a DHCP IP Address LeaseWait until the renewal process has completed (you receive an IP address). Then, stop the packet capture in Wireshark. Next, click on the column in the Packet List pane marked, “Protocol.” This will sort the entries in order of protocol.Locate the DHCP packets and select the first one. (There should be 5.)The first of these packets is from your computer to the DHCP server telling it to release the lease on your IP address. The next 4 packets renew that lease. Note that the source address on the “DHCP Discover” and “DHCP Request” packets is 0.0.0.0. This indicates that your computer does not actually use its new IP address until the interchange has completed. Also note that the destination address in each of the 4 packets is a broadcast address. It should be obvious to you why the first two packets are broadcasted, but what about the last two? Can you explain this? Answer the questions in your Word document right after you post a snapshot of the DHCP packet screen. (#4)Step 3: Following an HTTP streamLet’s have a closer look at a request/response interchange that requests a web site. Follow these steps to obtain a fresh set of packets:Ensure that your capture options are set as before and begin another capture session. You can discard the previous session or save it to a file.Open Internet Explorer on your workstation (it could be another browser if you so choose except edge), return to Wireshark and begin a packet capture session.Type in a URL and after the page loads, return to Wireshark and stop the packet capture.Find the packet with comments in the “Info” column saying “GET / HTTP/1.1” and select it. Right click this packet and click “Follow TCP stream” from the popup menu. See Figure 6.Figure 6: Follow TCP StreamA new window will open with the details of the http exchange. The request and acknowledgements from your workstation are in red, and the responses are in blue and should resemble Figure 7. Make a snapshot of the screen and post it in your Word document. (#5)Figure 7: Raw TCP Stream DataAt the bottom of this window are some options for saving this file for later reference. Click the “Close” button to return to the main window and you will notice that only the TCP and HTTP packets have been retained, since a filter was created based on your action of following the TCP stream. Now select File > Export > Objects > HTTP. See Figure 8. In the resulting window, find the Hostname you visited (second column; in our case, it was www.java.com; yours can be different.) and the content-type corresponding to text/html. Then, click the “Save As” button. Save the file (with a “.html” extension) on your desktop.Figure 8: Exporting TCP Stream (HTTP)Minimize all windows and find the file you just saved on the desktop and open it with a web browser. If the web page contains a number of secondary files, such as image, css, or flash files (as many web sites do), what you see won’t be very impressive; however, Figure 9 shows http://www.java.com on the left side, while its TCP stream produces the page shown on the right side of the figure. Although you can’t see the graphics in the rendered file, you can easily determine its main theme. Post this page into your Word document. (#6)Figure 9: Java.com (comparison) ___________________________________________________________________________________________________________________________________________________________You should notice that FTP login username and password are transferred in clear; not good at all for security.) OPTIONAL: Viewing an FTP transferWe will now look at the file transfer between an FTP client and an FTP server. You will need a second computer on your network capable of providing file transfer services (an FTP server). The easiest way to set up an FTP server is to download the open source program, Filezilla. It has both a server version that you can use to store files and a client version, which is used to access your server from another computer. Step 1: Setting up the FTP ServerDownload the Filezilla server from http://filezilla-project.org and install it on one computer. You can accept all the defaults for this demonstration, but you will need to create a user and assign a home directory to that user. Make sure you give the user a password but do not enable SSL. For this lab, we chose the username “johndoe” and a password “secret”. See Figure 10.Note: Your firewall may need to be configured to allow connections to FileZilla Server.Figure 10: Creating an FTP user in FileZillaDownload the Filezilla client from the same website as above and install it on a second computer. You can accept all the defaults including having the program start after installation. Step 2: Monitor the FTP login exchangeTo see the packet interchange between the two computers, perform the following:Open Wireshark on the client, ensure that your capture options are set as before and begin another capture session.Connect to the FTP server by typing in its IP address, user name and password in the text boxes at the top of the client software, then press “Quickconnect”. This is shown in Figure 11.Figure 11: Connecting to the FTP ServerStop the packet capture.Look for the FTP packets in the Protocol column (or apply a filter to show only ftp protocol packets). In the “Info” column they will say “Request: …” and “Response: …” You should notice that the username and password are displayed for you in this column in clear text. This is shown in Figure 12.If you have never seen a password revealed in a packet sniffer, it can be a real eye opener. Although we know that FTP servers are inherently not secure, this demonstration should make you think about the security of other types of logins. Try this: if you have a domain controller on your network, try logging on to it from a workstation and sniffing the packets as you do so. Are you able to find the password? (Hopefully not.) Now set up a database server for which the security setting is controlled by the operating system and do the same thing. If the security is not configured correctly, not only will you be able to find the login information (user name and password), but data will be passed in the clear also.Figure 12: An FTP Login Sequence in Wireshark Part 3: Write questions and answers to the following and post in your Word document.QuestionsPacket sniffing can be a controversial subject.

Ethics in Australia’s Banking Industry
term paper help Ethics in Australia’s Banking Industry. Introduction Business ethics incorporates professional or applied ethics which assesses the moral and ethical principles that can emerge within the business environment (De George, 2011). This essay has discussed about the different argument about the banking sector as an ethical and unethical. It shows the different corrupt Australian bank as an example for the argument of ethical behavior. . Ethics is crucial in any type of industry and the banking industry is not exempt from it. Ethics in banking encompasses careful consideration of its activities such as ethical investment, the impact of its investment, fair trade movement, ethical consumerism, and corporate social responsibility. Ethical banking upholds principles such as transparency in their activities, social and environmental values. With various cases of management accounting emerging in recent times, the significance of ethics in the banking sector has only increased many folds (Carrasco, 2006). Ethical issues in Australia’s banking in recent year have been highlighted by the Banking Royal Commission in its 2018 report. In situations where banks fail to uphold the ethical standards in its operation, the interest of the entire stakeholder is at risk that can result in an economic and social loss to even redundant friction within the economy. Body Koslowski, (2011) suggests that ethical banking operates in on the principle that what banks do with the money and the way they treat people matters and it goes beyond the topic of how banks invest their profits. Banks that endorses ethical practices in their operation ensures that they have strong sustainable credentials, practices ethics in all levels of the organization and commits to transparency. Incorporating business ethics makes sure that a certain level of confidence is established and exists between the organization, consumers and multiple forms of market participants. It ensures that all the parties involved in the business with the organization are treated fairly. Business ethics goes beyond just the moral belief of doing right and wrong; it seeks to reconcile the activities that companies need to do legally against developing a competitive edge in the market. Ethical conduct in banking is as important as in any other sector as it brings a number of benefits to the table such as attracting customers, employee’s retention, improve the brand image of the company, and attract investors towards the company. Business ethics and the banking industry Lumsden, (2019) suggests that with the recent turmoil that has been seen in the banking sector in Australia, put forth by the Banking Royal Commission, the significance of ethics in business has only increased that many folds. Banks are entrusted to act in a way that promotes trust of the public in them, confidence, and infusing values like integrity, responsibilities, fairness, accountability, and respect in all of the bank’s dealings. Though these are the beliefs and conducts that banks are expected to carry out, recent scandals and the crisis have led to public generating a belief that the banking industry has some fundamental issue with them. A number of studies highlight that different banks are linked with accepting bribes for loans, cheating customers, bias while lending and so forth. These acts show that fraudulent financial practices in recent times have become somewhat of culture in banks for achieving personal gains. Though a number of legislations has been laid down by concerned authorities in order to regulate the banking operations in Australia, at times it is not enough on its own to guarantee that banks are disciplined. Ethics begins where legislation ends and banks need to strive to be ethical in their actions as unethical actions often lead to the economic and social loss. Banks that fail to meet ethical standards in their operation puts the interest of all the parties at risk as evident from the different banking scandals in Australia (Lodhia, 2015). Some examples of unethical conduct within the Australian banking industry are Westpac subsidiary paying $493,000 as a penalty for breaching consumer protections, ANZ reporting three breaches of dispute resolution requirements, Commonwealth Bank offering $3 million as compensation for financial advice to date and so forth. These incidents show that the needs for ethical business practice in the Australian banking industry are greater than ever before. Ethical theories To better understand the aspect of ethics in business, relevant theories of ethics can play a crucial role (Casali, 2011). The major theories related to the ethics in business are utilitarianism, deontology, care ethics, egoism and virtue ethics. Utilitarianism advocates that action conduct is morally correct as long as it brings the greatest amount of happiness and good to the highest possible number of people that are affected by that particular action. As per utilitarianism theory, an individual or company needs to choose the action that results in the greatest happiness in general while maximizing the positive outcome for the largest number of people. Deontology or Kant’s ethical theory, on the other hand, stresses the moral significance of the action lies in the principle of the person’s action or conduct. It advocates that one need to choose an action or conduct that best conforms to one’s recognized duties and responsibilities. Under it, the morality of an action is judged against the adherence to the rules. Egoism theory explains what makes an action good or bad is the actions ability to satisfy one’s desires or meet one’s needs. As per egoism, an action whose consequences benefits the action taker it is considered as ethical. Care ethics centers on the action that seeks to care and build an interpersonal relationship with others. It puts forth the principle that an action that is carried out to care for others who need support and are vulnerable is ethical. Care ethics theory is generally considered to be a supplement to other theories rather than being a comprehensive theory in its own. Virtue ethics emphasizes the virtue of mind and character. Under virtue theory, an action can be ethical if it embodies or promotes aspects that are culturally acknowledged as right or wrong. It is crucial to understand that different traditions develop a different list of virtues making single action right in one place and wrong in another. Through better understanding the ethical theories, the banking sector can adopt principles of mutual trust, good intentions, mutual benefit and interest, the conflict between one’s own interests and ethical improvement of business behavior (Buijs et al, 2008). Ethical issues in Australia’s banking Banking Royal Commission was established in 2017 to inquire and report about the misconduct in the Australian banking industry (O’Brien, 2019). The report indicated that banking sector in Australia displayed serious lack of ethical consideration as the inquiry noted that a number of financial institutions were involved in money laundering, turned blind eye to terrorism financing, indecency in foreign exchange trading, and ignored statutory responsibility of reporting. Furthermore, the report was able to uncover unethical behavior in the banking of Australia such as charging fees for no advice, selling useless insurance policies to indigenous groups, charging fees to dead people, and lying to regulators. This caused many investors to pull their investments from various banks as it noted that customers were relegated to second place in the companies. Due to these activities, the Banking Royal Commission highlighted some serious misconduct in the banks that consisted of frauds, bribery which are a major concern for ethical investors. Among the financial institutes that were investigated are some of the big institutions in the financial sector of Australia: Commonwealth Bank, Macquarie, National Australia Bank, Westpac, AMP, and ANZ (Davis, 2019). Majority of financial were conducting acts that abuse trust, due to these tighter rules to regulate the banking industry more closely is required. Through its report, the Royal Commission has pointed out a series of entrenched cultural issues that have emerged in the Australian banking sector. Conclusion Ethics in banking industry ensures that financial institutes consider the social as well as environmental impacts of its activities. It pushes banks in Australia towards activities like more ethical investment and consumerism, impact investment, socially responsible investment and so on. While banks that adopt ethical practices attract customers, investors and attains competitive advantage, those which fails to do so can impact not only social and economical aspect but lead to the total collapse of the institution. Through the ethical theories: utilitarianism, deontology, care ethics, egoism and virtue ethics the subject matter of ethics in banking can be better understood. The report produced by Banking Royal Commission highlights major breach of ethical elements in the Australian banking scene such as fraudulent activities, bribery and so forth.
