20+ practice questions focused on Advanced Topics: Wireless, Cloud, IoT, Cryptography — one of the most tested topics on the Certified Ethical Hacker CEH exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Advanced Topics: Wireless, Cloud, IoT, Cryptography PracticeA security analyst captures a large number of unique initialization vectors (IVs) from a wireless network using airodump-ng. Which attack are they MOST likely preparing to execute?
Explanation: WEP encryption is vulnerable to statistical attacks that require capturing many unique IVs to recover the WEP key. The large number of unique IVs indicates preparation for a WEP cracking attack using a tool like aircrack-ng.
During a penetration test, an analyst runs the following command: 'reaver -i wlan0mon -b 00:11:22:33:44:55 -vv'. What is the PRIMARY purpose of this command?
Explanation: Reaver is a tool designed to exploit the WPS PIN authentication mechanism. The command targets a specific BSSID to perform a brute-force attack on the WPS PIN, which can reveal the WPA/WPA2 passphrase if successful.
A cloud security engineer discovers that an S3 bucket named 'acme-backups' is accessible to anyone with the bucket URL. The bucket contains sensitive customer data. Which AWS shared responsibility model component does this misconfiguration primarily violate?
Explanation: Under the AWS shared responsibility model, the customer is responsible for configuring S3 bucket policies and access controls. The misconfiguration is a customer-side issue, not an infrastructure vulnerability.
An IoT device uses the MQTT protocol without any authentication or encryption. An attacker on the same network subscribes to all topics on the MQTT broker. Which of the following is the MOST effective immediate countermeasure?
Explanation: MQTT without authentication and encryption can be secured by enabling TLS for transport encryption and requiring credentials for clients. This prevents unauthorized access and eavesdropping.
Which cryptographic algorithm is classified as symmetric and uses a block cipher with a fixed block size of 128 bits, supporting key sizes of 128, 192, and 256 bits?
Explanation: AES is a symmetric block cipher with a block size of 128 bits and supports key sizes of 128, 192, and 256 bits. It is the most widely used symmetric encryption standard.
