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)
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]
A startup firm contains various devices connected to a wireless network across the floor. An AP with Internet connectivity is placed in a corner to allow wireless communication between devices.

Stella purchased a smartwatch online using her debit card. After making payment for the product through the
payment gateway, she received a transaction text message with a deducted and available balance from her
bank.
Identify the information security element that ensures that Stella's transaction status is immediately reflected in her bank account in this scenario.
Answer : C
Availability is the information security element that ensures that Stella's transaction status is immediately reflected in her bank account in this scenario. Information security is the practice of protecting information and information systems from unauthorized access, use, disclosure, modification, or destruction. Information security can be based on three fundamental principles: confidentiality, integrity, and availability. Confidentiality is the principle that ensures that information is accessible only to authorized parties and not disclosed to unauthorized parties. Integrity is the principle that ensures that information is accurate, complete, and consistent and not altered or corrupted by unauthorized parties. Availability is the principle that ensures that information and information systems are accessible and usable by authorized parties when needed. In the scenario, Stella purchased a smartwatch online using her debit card. After making payment for the product through the payment gateway, she received a transaction text message with a deducted and available balance from her bank. This means that her transaction status was immediately reflected in her bank account, which indicates that availability was ensured by her bank's information system.
