ALB support in load balancer role for case of auto scaling vSEC in AWS

[Alex_Kharkevich]

I'm trying to figure out how to build a vSEC auto scale cluster.
My investigation based on:
- Solution sk112575 vSEC for AWS
- Presentation from TechTalk "Cloud Security Best Practices"

I have a stupid question - what kind types of load balancers can be used for vSEC sandwich, as on 22 slide from presentation or on Network Diagram from solution.

Is ALB supported as an external and internal load balancer?

Thanks,

Alex.
