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. 

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.

WPA3 encryption is the type of wireless encryption used by the security solution employed by Matias in the above scenario. WPA3 encryption is the latest and most secure version of Wi-FiProtected Access, a protocol that provides authentication and encryption for wireless networks. WPA3 encryption uses 256-bit Galois/Counter Mode Protocol (GCMP-256) to maintain the authenticity and confidentiality of data. WPA3 encryption also provides enhanced protection against offline dictionary attacks, forward secrecy, and secure public Wi-Fi access . WPA2 encryption is the previous version of Wi-Fi Protected Access, which uses Advanced Encryption Standard (AES) or Temporal Key Integrity Protocol (TKIP) for data encryption. WEP encryption is an outdated and insecure version of Wi-Fi security, which uses RC4 stream cipher for data encryption. WPA encryption is an intermediate version of Wi-Fi security, which uses TKIP for data encryption.
