Discuss EC-Council 212-82 Exam Topic 3 Question 28

An loT device placed in a hospital for safety measures has sent an alert to the server. The network traffic has been captured and stored in the Documents folder of the "Attacker Machine-1". Analyze the loTdeviceTraffic.pcapng file and identify the command the loT device sent over the network. (Practical Question)

ATempe_Low

BLow_Tem p e

CHigh_Tcmpe

DTemp_High

Suggested Answer: D

The loT device sent the command Temp_High over the network, which indicates that the temperature in the hospital was above the threshold level. This can be verified by analyzing the loTdeviceTraffic.pcapng file using a network protocol analyzer tool such as Wireshark4. The command Temp_High can be seen in the data field of the UDP packet sent from the loT device (192.168.0.10) to the server (192.168.0.1) at 12:00:03. The screenshot below shows the packet details5: Reference: Wireshark User's Guide, [loTdeviceTraffic.pcapng]

Are we sure the traffic wasn’t tampered with?

Theola 11 months ago

Totally agree with Anabel, that makes the most sense!

Kathryn 11 months ago

Why would an IoT device send a low temp alert? Seems odd.

Bo 12 months ago

I think it’s actually Temp_High.

Anabel 12 months ago

Looks like the command is Temp_Low.

Ashanti 1 year ago

I’m leaning towards "Temp_High" because it sounds like something an IoT device would report, but I’m not entirely confident.

Tenesha 1 year ago

I feel like I’ve seen a command like "Temp_Low" before, but I can't recall if it was in the context of IoT devices.

Geraldo 1 year ago

This question seems similar to the one we did on network traffic analysis last week. I think the command might be related to temperature settings.

Meghann 1 year ago

I remember we practiced analyzing pcap files, but I’m not sure how to identify the specific command sent by the IoT device.

Major 1 year ago

Network traffic analysis, huh? That's not my strongest suit, but I'll do my best to work through this step-by-step and see if I can figure out the answer.

Alayna 1 year ago

Okay, let's see what we've got here. Analyzing a pcapng file to find a specific command sent by an IoT device - this could be a challenge, but I'll give it my full attention.

Ashlyn 1 year ago

Ah, this is right up my alley! I've done plenty of network forensics in the past, so I'm confident I can crack this case.

Janine 1 year ago

This looks like a classic network traffic analysis question. I'll need to carefully review the pcapng file to identify the specific command sent by the IoT device.

Arlie 1 year ago

Hmm, I'm a bit unsure about this one. Analyzing network traffic can be tricky, but I'll give it my best shot and try to identify the command.

Sanjuana 1 year ago

This question seems straightforward, but I want to make sure I understand the key details before answering. The failure mode analysis table has two main components - priority and detection. I'll need to carefully consider which stakeholders would be best suited to contribute to each of those.

Una 1 year ago

Hmm, I'm a little unsure about this one. I'm thinking option A might be a good place to start, checking the request logs for any clues about the error. But I'll need to think it through a bit more.

Helene 2 years ago

Interesting. High temperature alert could indeed push an alert.

Carlee 2 years ago

I disagree, 'Temp_High' seems more urgent for an alert.

Shoshana 2 years ago

I think the command is 'Tempe_Low'. Makes sense for safety.

Viki 2 years ago

Yeah, but it’s a practical one. We need to check the .pcapng file.

Helene 2 years ago

Seems tricky, analyzing traffic isn't straightforward.

What do you think about that IoT device question?
