GPEN · Question #318

Which of the following attacks can be overcome by applying cryptography?

The correct answer is C. Sniffing. Cryptography encrypts data in transit, directly neutralizing sniffing attacks that rely on reading plaintext packets captured from the network.

Why each option

Cryptography encrypts data in transit, directly neutralizing sniffing attacks that rely on reading plaintext packets captured from the network.

AWeb ripping

Web ripping uses automated tools to copy publicly accessible web content from a server, a process cryptography does not prevent because the attacker retrieves data through normal HTTP requests.

BDoS

DoS attacks flood network resources with excessive traffic to deny service availability - cryptography does not reduce traffic volume or protect resource capacity.

CSniffingCorrect

Sniffing attacks passively capture network packets to extract sensitive information from plaintext traffic. Applying cryptography - such as TLS/SSL - encrypts the data payload so intercepted packets are unreadable without the decryption key. This makes encryption a direct and effective technical countermeasure against sniffing.

DBuffer overflow

Buffer overflow attacks exploit memory management flaws in application code at the software layer - cryptography operates on data confidentiality and cannot prevent or mitigate memory corruption vulnerabilities.
