Which SMB (Server Message Block) network protocol version introduced support for encrypting SMB traffic?

ASMBv1

BSMBv2

CSMBv3

DNone of the above

Suggested Answer: C

The SMB protocol, used for file and printer sharing, has evolved across versions, with significant security enhancements in later iterations.

Why C is correct: SMBv3, introduced with Windows 8 and Server 2012, added native support for encrypting SMB traffic. This feature uses AES-CCM encryption to protect data in transit, addressing vulnerabilities in earlier versions. CNSP notes SMBv3's encryption as a critical security improvement.

Why other options are incorrect:

A . SMBv1: Lacks encryption support and is considered insecure, often disabled due to vulnerabilities like WannaCry exploitation.

B . SMBv2: Introduces performance improvements but does not support encryption natively.

D . None of the above: Incorrect, as SMBv3 is the version that introduced encryption.

I thought SMBv2 had some security features too, but I guess not.

Totally agree, SMBv3 is the way to go.

Gertude 10 months ago

Wait, SMBv1 had no encryption? That's surprising!

Lavera 10 months ago

SMBv2 doesn't have encryption, just SMBv3.

SMBv3 introduced encryption support!

Elfrieda 11 months ago

I vaguely recall a practice question about SMB encryption, and it pointed towards SMBv3 as well.

I’m pretty certain that SMBv3 added encryption, but I might be mixing it up with another protocol.

Catalina 11 months ago

I remember studying about SMB versions, and I feel like SMBv2 was more about performance improvements.

Gaston 12 months ago

I think SMBv3 is the one that introduced encryption, but I’m not 100% sure.

Malissa 12 months ago

I'm feeling confident about this one. I remember learning that SMBv3 was the version that introduced support for encrypting SMB traffic to improve security. I'll select C as my answer.

Murray 12 months ago

Okay, let me think this through step-by-step. SMBv1 was the original version, SMBv2 added some improvements, and I believe SMBv3 is the one that focused on security features like encryption. I'm going to go with C for SMBv3.

Hmm, I'm a bit unsure about this one. I know SMB has gone through several versions, but I can't recall off the top of my head which one added encryption. I'll have to think this through carefully.

I'm pretty sure it's SMBv3 that introduced encryption support, but I'll double-check the details just to be sure.

Willard 1 year ago

I believe it's C) SMBv3 because it's the latest version and likely to have added encryption support.

I agree with Gail, SMBv3 introduced support for encrypting SMB traffic.

D) None of the above? Really? Clearly the person who wrote this question needs to brush up on their SMB protocol knowledge.

C'mon, let's be real - if it's not SMBv3, it's not worth my time. Gotta keep those hackers at bay, you know?
