How can device impersonation attacks be effectively prevented in a

ZTA?

Show Suggested Answer Hide Answer
Suggested Answer: D

SPA is a security protocol that prevents device impersonation attacks in a ZTA by hiding the network infrastructure from unauthorized and unauthenticated users. SPA uses a single encrypted packet to convey the user's identity and request access to a resource. The SPA packet must be digitally signed and authenticated by the SPA server before granting access.This ensures that only authorized devices can send valid SPA packets and prevents spoofing, replay, or brute-force attacks12.

Single packet authorization (SPA) was highlighted in our last session as a way to verify device identity, so I’m leaning towards that as a strong option.

I think organizational asset management might help, but it feels more like a general security practice rather than a direct prevention method for impersonation.

Micro-segmentation seems like a good option since it limits lateral movement, but I can't recall if it was specifically mentioned for device impersonation.

I remember we discussed strict access control in class, but I'm not entirely sure how it directly relates to preventing impersonation attacks.

Organizational asset management seems like it might be a bit too broad for this specific question. I'll focus my answer on the more targeted security measures like access control and micro-segmentation.

Single packet authorization (SPA) sounds like it could be a good solution here. I'll need to make sure I understand how SPA works to secure against impersonation attacks.

Okay, I've got this. Strict access control and micro-segmentation are both key to preventing device impersonation in a ZTA. I'll explain how each of those work in my answer.

Hmm, I'm a bit unsure about this one. I'll need to review my notes on ZTA security measures to decide which approach would be most effective.

This seems like a straightforward question about the underlying data used for dashboard alerts. I'll carefully review the options and think through what type of data would typically be used for this purpose.

I'm pretty sure both “Elastic Scale-Out” and “Scale-In” are standard features, but “Elastic Self-Health” sounds confusing to me. It doesn't ring a bell.
