Exam CS0-002 topic 1 question 406 discussion

Correction the answer is A

The line from this output that most likely indicates that attackers could quickly use brute force and determine the negotiated secret session key is TLS_DHE_RSA_WITH_AES_128_CBC_SHA 128 DH (1024 bits). This line indicates that the cipher suite uses Diffie-Hellman ephemeral (DHE) key exchange with RSA authentication, AES 128-bit encryption with cipher block chaining (CBC) mode, and SHA-1 hashing. The DHE key exchange uses a 1024-bit Diffie-Hellman group, which is considered too weak for modern security standards and can be broken by attackers using sufficient computing power. The other lines indicate stronger cipher suites that use longer key lengths or more secure algorithms.

"A machine that can crack a DES key in a second would take 149 trillion years to crack a 128-bit AES key. Hence, it is safe to say that AES-128 encryption is safe against brute-force attacks. AES has never been cracked yet and it would take large amounts of computational power to crack this key."
