Windows Registry Analysis

• The Windows Registry contains information about software installation and the last use of software that is often of forensic value.
• Normally a user uses the Control Panel and Properties to make changes to the Registry. The registry is made up of “keys” which act like folders. (HKEY is short for “handler to key”)

o   HKEY_CLASSES_ROOT

• HKEY_CLASSES_ROOT stores information about registered applications.

o   HKEY_CURRENT_USER

• HKEY_CURRENT_USER stores settings for the user currently logged in.

o   HKEY_LOCAL_MACHINE

• HKEY_LOCAL_MACHINE stores general settings for all users on the computer.

o   HKEY_USERS

• HKEY_USERS contains subkeys corresponding to the HKEY_CURRENT_USER keys for each registered user on the machine.

o   HKEY_CURRENT_CONFIG

• HKEY_CURRENT_CONFIG contains configuration information regenerated when the system boots.

Step 1: Regedit

Note: Use caution, editing the Registry directly can result in an unstable system

• Go to Start->Run and enter: cmd
• At the prompt, type: regedit.exe to run the Registry Editor
• Look under HKEY_CURRENT_USER->Software->Microsoft->Internet Explorer->Typed URLs to view URLs the user has actually typed in.
  • Imagine this scenario: The subject of an investigation claims that spyware caused child porn to be downloaded to his machine.  If it can be shown that he actually typed in the URL, then his defense is weakened.
• You can exit Regedit.

Step 2: NTUSER.dat

• Help finding the NTUSER.dat file:
  https://www.techwalla.com/articles/what-is-the-ntuserdat-file
• Often, when examining an acquired disk image, you will want to examine the registry that applies to a particular user.
• This information is stored in a file called NTUSER.dat.
• There is an NTUSER.dat file for each user.
• We can’t access that file right now since it is in use, so we will have you go to the Control Panel and create a new limited account.
• Log off and login to your new account
• Launch Internet Explorer and type in a few URLs
• Then log off and log back into your original account.
• Open the Registry Viewer Application (click OK when it complains about the lack of a dongle)
  • File->Open the NTUser.dat file (not the Log file)
• Open the file and drill down to Software->Microsoft->IE->TypedURLs
  • ANSWER QUESTIONS 4 – 7

Step 3: Use WRR to Examine the NTUser.dat File

• Launch Windows Registry Recovery (WRR)
• Choose File->Open
• Browse until you locate your new account
• Find and open the file NTUSER.dat (not the text file, which contains the log)
• Choose RawData
• Choose Software->Microsoft->IE->TypedURLs

Recycle Bin

• When files are sent to the Recycle bin, they are stored in a folder called Recycled (FAT systems), Recycler (XP), or $Recycle.Bin (Vista, Windows 7, 8, 10).
  • Note that you can delete a file by holding down the shift key while deleting to avoid sending it to the Recycle Bin.
  • $Recycle.Bin

$I08C8KJ.jpg

• Administrative file. This is actually a text file, despite the extension. Forensic information includes the file size and date and time of deletion.

$R08C8KJ.jpg

• Actual file

Introduction

Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL supports data rates of up to 9 Mbps1 downstream and 640 Kbps2 upstream.

ADSL technology provides many benefits to users including higher data rates, longer reach, and support for multiple services over a single connection. These benefits come at a cost, however, as the increased data rates and longer reach of ADSL service can result in increased noise and attenuation3. These problems can lead to data errors and packet loss, which can in turn lead to degraded service quality and decreased user satisfaction.

In order to troubleshoot these problems, it is necessary to have a tool that can accurately simulate ADSL service. Packet Tracert is such a tool, and it is the focus of this dissertation. Packet Tracert is a packet-level simulator that can be used to troubleshoot ADSL service. It can simulate various ADSL technologies, including ADSL2 and ADSL2+.

This dissertation will discuss the use of Packet Tracert to troubleshoot ADSL service. It will begin with a discussion of the basics of ADSL technology. This will be followed by a discussion of the features of Packet Tracert that make it well suited for troubleshooting ADSL service. Finally, the dissertation will conclude with a discussion of the results of using Packet Tracert to troubleshoot ADSL service.

Assymetric Digital Subscriber Line Trouble Shooting Stimulation using Packet Tracrer

Introduction

The research project titled ‘Assymetric Digital Subscriber Line Trouble Shooting Stimulation using Packet Tracrer’ is aimed at finding a solution to the problem of troubleshooting Asymmetric Digital Subscriber Line (ADSL) connections. The project is to develop a tool that can be used to simulate various ADSL connection troubles and determine the cause of the problem.

ADSL is a type of broadband connection that uses digital technology to provide high-speed Internet access. It is a popular choice for home users and small businesses because it is relatively affordable and easy to install. However, ADSL can be notoriously difficult to troubleshoot. This is because the connection is often made through a telephone line, which can be susceptible to interference from other electrical equipment.

There are many different reasons why an ADSL connection may experience problems. The most common cause of ADSL trouble is interference from other electrical equipment. This can include anything from microwaves to electrical wiring. Other causes of ADSL problems can include bad weather, line noise, and equipment failure.

The ‘Assymetric Digital Subscriber Line Trouble Shooting Stimulation using Packet Tracrer’ project is to develop a tool that can simulate various ADSL connection troubles and determine the cause of the problem. The tool will be used to create a virtual ADSL connection and then simulate various problems that can occur. The results of the simulations will be used to determine the cause of the problem and provide a solution.

The ‘Assymetric Digital Subscriber Line Trouble Shooting Stimulation using Packet Tracrer’ project is a valuable research project that has the potential to provide a solution to the problem of troubleshooting ADSL connections. The project has the potential to make a significant contribution to the field of broadband technology.

Background study

Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. It does this by utilizing frequency-division multiplexing (FDM) to split the bandwidth of the line into multiple channels, one for upstream data and one for downstream data. This allows for a much higher data rate than is possible with voiceband modems.

ADSL was originally developed by telephone companies to offer higher-speed services to their customers. However, ADSL has become popular with home users and small businesses as a way to connect to the Internet at speeds much higher than those possible with a dial-up modem.

ADSL is available in a number of different flavors, including:

* ADSL Lite: Also known as G.lite, this is a version of ADSL that has been standardized by the International Telecommunication Union (ITU). ADSL Lite is designed for use over standard copper telephone lines and is the most widely available type of ADSL.

* Rate-Adaptive ADSL (RADSL): This is a type of ADSL that automatically adjusts the data rate to match the quality of the line. RADSL is typically used on longer lines or lines with a higher noise level.

* Very-high-bit-rate ADSL (VDSL): Also known as HDSL2, this is a type of ADSL that offers data rates of up to 52 Mbps over short distances (up to 3000 feet). VDSL is typically used by telephone companies to offer high-speed Internet access to business customers.

* Wireless ADSL (WDSL): This is a type of ADSL that uses a wireless connection between the customer’s premises and the telephone company’s central office. WDSL is typically used in areas where it is not practical to run a physical connection.

To connect to the Internet using ADSL, you will need an ADSL modem. ADSL modems are available from a number of different manufacturers, including:

* 3Com

* Agere

* Alcatel

* Cisco

* D-Link

* Lucent

* Motorola

* Netgear

* Nokia

* Siemens

* US Robotics

* Zenith

In addition to an ADSL modem, you will also need a computer with an Ethernet card and an ADSL-compatible telephone line. Most ADSL modems also come with a built-in Ethernet switch, which allows you to connect multiple computers to the modem.

Once you have all of the necessary equipment, you will need to connect the ADSL modem to the telephone line and the computer. The specific connection process will vary depending on the type of modem you are using, so consult the manual that came with your modem for specific instructions.

Once the modem is connected, you will need to configure the computer for ADSL. The specific configuration process will again vary depending on the type of modem you are using, so consult the manual that came with your modem for specific instructions.

Once the computer is configured, you will be able to connect to the Internet using your ADSL connection. The speed of your connection will depend on a number of factors, including the distance between your computer and the telephone company’s central office, the quality of the line, and the type of ADSL modem you are using.

Requirements and Analysis

The objectives of this project are to design and implement a system that can automatically troubleshoot Asymmetric Digital Subscriber Line (ADSL) problems, and to evaluate the effectiveness of the system.

The objectives of this project are to design and develop a system that can automatically troubleshoot Asymmetric Digital Subscriber Line (ADSL) problems by simulating different ADSL connection scenarios and measuring the performance of the connection. The system will use a packet tracer to generate different ADSL connection scenarios and then measure the performance of the connection in terms of data rate, packet loss, and delay. The system will then compare the results of the simulation with the results of the actual ADSL connection to identify the cause of the problem.

The first step in the analysis is to understand the ADSL connection and the different factors that can affect its performance. The second step is to identify the different ADSL connection scenarios that can be simulated using the packet tracer. The third step is to develop a performance measurement system that can be used to measure the data rate, packet loss, and delay of the ADSL connection. The fourth step is to develop a comparison system that can compare the results of the simulation with the results of the actual ADSL connection.

ADSL is a type of digital subscriber line (DSL) technology that uses asymmetric digital signaling to provide high-speed Internet access. ADSL is much slower than symmetric DSL (SDSL), but it is less expensive and can be used over longer distances. The main factor that affects the performance of ADSL is the distance between the ADSL modem and the central office (CO). The further the distance, the lower the data rate and the higher the packet loss.

There are two types of packet loss: random packet loss and burst packet loss. Random packet loss occurs when the packets are lost due to errors in the transmission process. Burst packet loss occurs when the packets are lost due to congestion in the network. Congestion can be caused by heavy traffic or by a faulty connection.

The data rate of the ADSL connection can be affected by the type of modulation used. The most common type of modulation used in ADSL is Discrete Multi-Tone (DMT). DMT uses a large number of closely spaced carriers to send data. The data rate of the ADSL connection can also be affected by the number of bits per tone (BPT). The higher the BPT, the higher the data rate.

The delay of the ADSL connection can be affected by the type of line used. The most common type of line used in ADSL is a twisted pair line. Twisted pair lines are made up of two wires that are twisted around each other. The twist helps to cancel out the noise on the line. The delay of the ADSL connection can also be affected by the length of the line. The longer the line, the higher the delay.

The fourth step in the analysis is to develop a system that can automatically troubleshoot ADSL problems by simulating different ADSL connection scenarios and measuring the performance of the connection. The system will use a packet tracer to generate different ADSL connection scenarios and then measure the performance of the connection in terms of data rate, packet loss, and delay. The system will then compare the results of the simulation with the results of the actual ADSL connection to identify the cause of the problem.

3.2.1 Breaking Down the Problem

The first step in the analysis is to break down the problem into smaller, more manageable parts. In this case, the problem of troubleshooting ADSL problems can be broken down into the following smaller problems:

1. Identifying the cause of the problem
2. Isolating the problem
3. Troubleshooting the problem

3.2.2 Identifying the Cause of the Problem

The first step in troubleshooting any problem is to identify the cause of the problem. In the case of ADSL problems, there are a number of potential causes that need to be considered, including:

1. Physical layer problems
2. Data link layer problems
3. Network layer problems
4. Application layer problems

3.2.3 Isolating the Problem

Once the cause of the problem has been identified, the next step is to isolate the problem. In the case of ADSL problems, this may involve:

1. Checking the physical connection between the ADSL modem and the computer
2. Checking the ADSL modem settings
3. Checking the computer settings
4. Checking for line noise

3.2.4 Troubleshooting the Problem

Once the problem has been isolated, the next step is to troubleshoot the problem. In the case of ADSL problems, this may involve:

1. Restarting the ADSL modem
2. Reconfiguring the ADSL modem
3. Reconfiguring the computer
4. Replacing the ADSL modem
5. Checking the line for noise

3.2.5 Evaluating the Effectiveness of the System

Once the system has been designed and implemented, it is important to evaluate the effectiveness of the system. In the case of this system, this will involve:

1. Testing the system with a variety of ADSL problems
2. Evaluating the results of the tests
3. Comparing the results of the tests with the results of manual troubleshooting
4. Drawing conclusions about the effectiveness of the system

Conclusions

This chapter brings together many of the points that you will have made in other chapters, especially in the previous results and discussion chapter. The purpose of this chapter is to:

– Review the main findings of the study

– Discuss the implications of the findings

– Make recommendations for future research

– Summarise the key points of the dissertation

The findings of the study can be divided into two main categories: those relating to the technical aspects of the ADSL network and those relating to the user experience.

From the technical perspective, the study found that the biggest cause of ADSL problems is interference from other sources, such as electrical equipment or wiring. This interference can cause packet loss, which in turn leads to slow speeds and intermittent connection problems.

The study also found that the second biggest cause of ADSL problems is line noise. Line noise can be caused by a number of factors, including poor quality wiring, water damage, or bad connectors. Line noise can also be caused by interference from other electronic equipment, such as microwaves or cordless phones.

Finally, the study found that the third biggest cause of ADSL problems is poor signal quality. This can be caused by a number of factors, including distance from the exchange, line attenuation, or poor wiring.

From the user perspective, the study found that the biggest cause of ADSL problems is incorrect router configuration. This can be caused by a number of factors, including incorrect settings, outdated firmware, or incompatible hardware.

The study also found that the second biggest cause of ADSL problems is user error. This can be caused by a number of factors, including incorrect password, forgotten login details, or incorrect settings.

Finally, the study found that the third biggest cause of ADSL problems is line noise. Line noise can be caused by a number of factors, including poor quality wiring, water damage, or bad connectors. Line noise can also be caused by interference from other electronic equipment, such as microwaves or cordless phones.

The implications of the findings are that the ADSL network is vulnerable to a number of problems, both technical and user-related. In order to improve the reliability of the ADSL network, it is necessary to address both sets of problems.

The recommendations for future research are as follows:

– Further research is needed into the technical causes of ADSL problems, in order to develop more effective solutions.

– Further research is needed into the user experience of ADSL problems, in order to develop more user-friendly solutions.

– Further research is needed into the line noise problem, in order to develop more effective solutions.

Critical Thinking

Increased global competition leads the industry to increasing efficiency by means of economies of scale and internal specialization so as to meet market conditions in terms of flexibility, delivery performance and quality (Yamashina, 1995). The changes in the present competitive business environment are characterized by profound competition on the supply side and keen indecisive in customer requirements on the demand side. These changes have left their distinctive marks on the different aspect of the manufacturing organizations (Gomes et al., 2006). With this increasing global economy, cost effective manufacturing has become a requirement to remain competitive.

The global marketplace has witnessed an increased pressure from customers and competitors in manufacturing as well as service sector (Basu, 2001; George, 2002). Due to the rapidly changing global marketplace only those companies will be able to survive that will deliver products of good quality at cheaper rate and to achieve their goal companies try to improve performance by focusing on cost cutting, increasing productivity levels, quality and guaranteeing deliveries in order to satisfy customers (Raouf, 1994).

To meet all the challenges organizations try to introduce different manufacturing and supply techniques. Management of organizations devotes its efforts to reduce the manufacturing costs and to improve the quality of product. To achieve this goal, different manufacturing and supply techniques have been employed. The last quarter of the 20th century witnessed the adoption of world-class, lean and integrated manufacturing strategies that have drastically changed the way manufacturing firm’s leads to improvement of manufacturing performance (Fullerton and McWatters, 2002).
