Which authentication type in QRadar encrypts the username and password and forwards the username and password to the external server for authentication?

ARADIUS authentication

BTwo-factor authentication

CTACACS authentication

DSystem authentication

Suggested Answer: C

TACACS (Terminal Access Controller Access-Control System) authentication is a protocol used in IBM QRadar SIEM V7.5 for authenticating users by forwarding their credentials to an external server. Here's how it works:

Encryption: TACACS encrypts the entire payload of the authentication packet, including the username and password, ensuring secure transmission.

Forwarding Credentials: After encryption, the credentials are forwarded to an external TACACS server, which performs the actual authentication.

Authentication Process: The external server checks the credentials against its database and sends a response back to QRadar indicating whether the authentication is successful or not.

Reference IBM QRadar SIEM documentation explains TACACS authentication in detail, highlighting its secure encryption and external server verification process.

Totally agree, RADIUS is the way to go!

Yuette 10 months ago

I thought TACACS was the one that does that?

Leonor 10 months ago

It's definitely RADIUS authentication.

Slyvia 10 months ago

System authentication doesn't encrypt like that.

Tayna 10 months ago

Wait, are we sure about that? Seems too simple.

Dorothy 11 months ago

I have a vague memory of RADIUS being the standard for this kind of authentication, but I might be mixing it up with something else.

Freeman 11 months ago

I recall that two-factor authentication is more about adding an extra layer, not just encrypting credentials. So I think it’s probably not that one.

Nydia 11 months ago

I'm not entirely sure, but I feel like TACACS might also be related to this. It could be worth considering.

Kiley 11 months ago

I think RADIUS authentication is the one that encrypts the username and password before sending it. I remember practicing a similar question.

Lanie 12 months ago

RADIUS seems like the most likely answer based on the description, but I'll make sure to read through the options carefully before selecting my final answer.

Timothy 12 months ago

I'm leaning towards RADIUS, but I want to double-check the definitions of the other options just to be sure I'm not missing something.

Gianna 12 months ago

The key here is that the question is asking about the authentication type that encrypts the credentials and sends them to an external server. That sounds like RADIUS to me.

Luisa 1 year ago

Hmm, I'm a bit confused on the differences between the authentication types. I'll need to review my notes to make sure I understand the details of each one.

I'm pretty sure this is RADIUS authentication, since it mentions encrypting the username and password and forwarding them to an external server.

System authentication? More like 'system annoyance'! RADIUS is the way to go.

↳ replying to Albina

RADIUS authentication is definitely the way to go.

Filiberto 1 year ago

TACACS authentication? What is this, the '90s? RADIUS is where it's at, folks.

Rhea 1 year ago

↳ replying to Filiberto

I agree, RADIUS is much more secure than TACACS.

RADIUS authentication is definitely the way to go.

Sharmaine 1 year ago

I'm not sure, but I think B) Two-factor authentication also encrypts the credentials.

Alline 1 year ago

I agree with Lavelle, TACACS authentication encrypts the username and password.

Charlesetta 1 year ago

Two-factor authentication? Nah, that's too much work. I want the lazy option - RADIUS all the way!

Lonny 1 year ago

↳ replying to Charlesetta

Yeah, RADIUS is simple and gets the job done.

Shonda 1 year ago

↳ replying to Charlesetta

I agree, RADIUS is definitely the easier option.

Nakisha 1 year ago

RADIUS authentication sounds like the right answer to me. Gotta love that encrypted username and password action!

Ellen 1 year ago

↳ replying to Nakisha

RADIUS authentication provides that extra layer of security with encrypted username and password transmission.

Staci 1 year ago

↳ replying to Nakisha

Yeah, RADIUS authentication is definitely the best choice for forwarding credentials to an external server.

Mollie 1 year ago

↳ replying to Nakisha

I agree, RADIUS authentication is the way to go for secure username and password encryption.

Lavelle 1 year ago

I think the answer is C) TACACS authentication.
