Question

John works as a professional Ethical Hacker. He has been assigned the task of testing the that the following protocols of the We-are-secure server are being used in the network:

  • HTTP
  • SSL
  • SSH
  • IPSec

Considering the above factors, which of the following types of packets can he expect to see captured in encrypted form when he checks the sniffer's log file? Each correct answer represents a complete solution. Choose all that apply.

Options

  • ASSH
  • BIPSec
  • CHTTP
  • DSSL

Why each option

SSH, IPSec, and SSL all encrypt their traffic by design, while plain HTTP transmits data in cleartext and would appear unencrypted in a packet capture.

ASSHCorrect

SSH (Secure Shell) encrypts all data in transit using symmetric encryption after a key exchange, so any captured SSH packets appear as ciphertext in a sniffer log.

BIPSecCorrect

IPSec operates at the network layer and encrypts the payload (in tunnel or transport mode), meaning captured packets reveal no readable application data.

CHTTP

HTTP transmits all data, including headers, cookies, and body content, as plaintext with no encryption, so it would appear in clear, readable form in a sniffer log.

DSSLCorrect

SSL (and its successor TLS) encrypts the session after the handshake, so all application data carried over SSL appears encrypted in a packet capture.
