Topic #: 2
[All PCSFE Questions]

Which component can provide application-based segmentation and prevent lateral threat movement?

Show Suggested Answer Hide Answer
Suggested Answer: D

App-ID is the component that can provide application-based segmentation and prevent lateral threat movement. Application-based segmentation is a method of dividing the network into smaller segments or zones based on application or workload characteristics, such as function, dependency, owner, or security posture. Lateral threat movement is a technique used by attackers to move across the network from one compromised host to another, looking for sensitive data or assets. App-ID is a feature that identifies and classifies applications and protocols based on their content and characteristics, regardless of port, encryption, or evasion techniques. App-ID can provide application-based segmentation and prevent lateral threat movement by applying granular security policies based on application information to each segment or connection, blocking unauthorized access or data exfiltration. DNS Security, NAT, and URL Filtering are not components that can provide application-based segmentation and prevent lateral threat movement, but they are related features that can enhance security and visibility.

I thought NAT could help with that too?

I’m confused; I thought URL Filtering could also help with segmentation, but now I’m not so sure.

This question reminds me of a practice one we did on preventing lateral movement. I feel like App-ID was a key component there too.

I'm not entirely sure, but I remember something about DNS Security not being focused on segmentation.

I think App-ID might be the right answer since it deals with identifying applications and can help with segmentation.

App-ID is the way to go. It gives you that application-level visibility and control to stop threats from spreading across your network.

I'm a bit confused on this one. I know App-ID has something to do with application-level security, but I'm not sure if that's the right answer here. I'll have to review my notes.

Definitely App-ID. That's the component that can identify applications and control access to them, which is key for preventing lateral movement.

Hmm, I'm not too sure about this one. I'll have to think it through carefully. Maybe App-ID or URL Filtering could work?
