212-82 Exam Dumps : Certified Cybersecurity Technician (CCT)

To analyze the IoT network traffic capture and identify the command sent to IoT devices, follow these steps:

Open the Capture File:

Use a network analysis tool like Wireshark to open theIoT_capture.pcapngfile.

Filter and Analyze:

Apply appropriate filters to isolate relevant traffic. Look for command patterns typically sent to IoT devices.

Identify the Command:

Upon analyzing the captured traffic, the commandForest_Fire_Alert444is identified as the one sent over the network to IoT devices during the attack.

Analysis of IoT network traffic:IoT Security

The use of authorized RTU and PLC commands is the security control implemented by Hayes in the above scenario. RTU (Remote Terminal Unit) and PLC (Programmable Logic Controller) are devices that control and monitor industrial processes, such as power generation, water treatment, oil and gas production, etc. RTU and PLC commands are instructions that are sent from a master station to a slave station to perform certain actions or request certain data. The use of authorized RTU and PLC commands is a security control that fortifies the IDMZ (Industrial Demilitarized Zone) against cyber-attacks by ensuring that only valid and authenticated commands are executed by the RTU and PLC devices. Point-to-point communication is a communication method that establishes a direct connection between two endpoints. MAC authentication is an authentication method that verifies the MAC (Media Access Control) address of a device before granting access to a network. Anti-DoS solution is asecurity solution that protects a network from DoS (Denial-of-Service) attacks by filtering or blocking malicious traffic.

These firewalls operate by tracking the state and context of active connections, maintaining session information such as IP addresses and port numbers. They inspect packets at multiple layers of the OSI model, including the network, transport, and session layers.
