Overview
For the purposes of this activity, you are currently working as an IoT systems engineer and are tasked with reviewing the given IoT Architecture Diagram (the diagram is attached below) to determine any errors that may arise in the implementation or usage of the system. By reviewing this diagram, you can inform the IoT architect of the changes that need to be made.
Prompt
Create a document to inform your team of the architectural design errors. In your writing:
Identify at least 3 errors that may arise with the system. You must address the following for each potential error in the design you encounter:
What IoT device is the main component in this error? Are there multiple devices?
Is this design error something that requires a redesign of the system? Why or why not?
Can this system operate and function without addressing this error? Why or why not?
Then provide at least one alternative solution for each potential error you found. It is suggested that you prepare a paragraph for each solution to send to the IoT architect. Explain the potential error and the solution that they can use to alter the diagram. To complete this step, you must address the following for each error:
What do you think is the best solution to address this potential error? What are the device changes or system updates needed to complete this solution?
Does this solution address any issues with confidentiality, integrity, or availability of data within the system? Explain how it does or doesn’t.
What to Submit
Your submission must be a 2- to 3-page Word document (.docx).

Message:
THIS IS URGENT. Chikako called me at the help desk, saying his computer is up and working but cannot log into the domain. He has a meeting in 25 minutes and needs files and the PowerPoint for the meeting!
I cannot take over their machine remotely nor can I ping it. Can you help?

There are multiple potential solutions. You can pick one of the four below or have a different potential solution of your own.
bad cable
bad NIC
switch failure
DHCP server down
Focus on only one of the potential solutions for stepping through the six steps of the troubleshooting process. Answer the first four out of the six steps in your post. For the third CompTIA step, what would it take to prove your theory correct or incorrect? Example: If I do X and Y happens, then that is the issue. If Z happens, it is something else.
Classmate 1 Muhammad post
I would go with the theory that the issue could be due to a bad cable. Here’s how I would approach the first four steps of the troubleshooting process:
1. Identify the problem: Chikako is unable to log into the domain despite the computer being up and running.
2. Establish a theory of probable cause: The theory is that a bad cable might be causing the connectivity issue.
3. Evaluate the theory to determine the actual cause: To prove or disprove this theory, you can try replacing the cable with a known working one and see if the issue continues. If the problem is resolved, it confirms the theory. If not, then it’s likely something else causing the problem.
4. Establish a plan of action to resolve the problem and implement the solution: If the cable is indeed the cause, the plan of action would be to replace the faulty cable with a new one.
5. Verify full system functionality and implement preventative measures: After replacing the cable, I would check if Chikako can successfully log into the domain. Additionally, it would be a good idea to implement defensive measures like regularly checking and maintaining network cables to prevent future connectivity issues.
6. Document findings, actions, and outcomes: It’s important to document the entire troubleshooting process, including the identified problem, the theory of probable cause, the actions taken (such as replacing the cable), and the outcome (whether the issue was resolved or not). This documentation will help in future reference and troubleshooting.
Classmate 2 Isha post
Step 1: identify the problem
The problem is that It is not possible for Chikako’s computer to log into the domain, and pinging and remote access are not an option.
Step 2: Establish a theory of probable cause
Considering the symptoms, a DHCP server issue that prevents the machine from obtaining an IP address could be the root cause.
Step 3: Evaluate the theory to determine the actual cause.
I can Try giving the computer a static IP address by hand and see if that allows it to connect to the domain in order to verify this theory. Success would validate the failure of the DHCP server as the reason. On the other hand, I will do additional investigation into potential causes such as malfunctioning cables, NIC, or switch failure might be necessary if the problem continues.
Step 4: Establish a plan of action to resolve the problem and implement the solution.
I can also Try giving Chikako’s machine a static IP address by hand like in step 3 and then see if it can connect to the domain. If it works, I will report the possible failure of the DHCP server to the network team so that they can look into it more and find a solution. If it doesn’t work, I’ll try some further troubleshooting techniques to find and fix the underlying connectivity problem.

Detail of the task
You are required to design the transparent, accountable and privacy-preserving voting system described above (you can assume the availability of any crypto algorithms you need for the design), and document all the results obtained from each of the following tasks:
1. Anonymous creation of pseudo user name computer accounts for registered group members:
(a) Design a communication protocol for the above anonymous account creation, and describe what assumptions you have made and how the protocol operates. This account creation protocol should consist of messages transferred step by step between different parties/entities involved, where the details of all the data items sent in each message must be clearly defined.
You can assume that there exists a trusted server for assistance in the anonymous account creation process, but the server must not be able to link a pseudo user name to the real identity of any registered group member.
(b) Analyse how the designed protocol achieves both authenticity and anonymity.
2. Secure voting dissemination:
(a) Design a communication protocol for a registered group member to send their authenticated vote to all the other group members, and describe what assumptions you have made and how the protocol operates. Again, the details of all the data items sent in each message of this voting protocol must be clearly defined.
(b) Analyse how the proposed voting protocol achieves both confidentiality and authenticity.
Note that this is a team coursework. Each team has two students to work on the coursework. The module leader will assign students to each team. Please note that:
As a team, you need to work closely with your peer to complete the tasks defined above.
For the report writing, one team member must write up the sections for tasks 1 (a) and 2 (b), and the other team member must write up the sections for tasks 1 (b) and 2 (a). This means that each team member needs to write up the design of one of the two protocols and the analysis of the other, so close team working is essential.
You need to reach an agreement with your peer on who is responsible for which part of the report writing, and clearly state the agreed responsibility for each in the report.
You only need to submit a single report consisting of the two parts contributed by each team member.
Your mark will be awarded only for the part you are responsible for writing, and the maximum mark you can get is 50%.
You must not discuss or share the coursework with students in any other teams.
