Even though there's the AWS Certified Security Specialty Certification — which is well worth taking — I think at the start especially you're going to be a better security person if you learn how to build better.  So looking at the DevOps exams and the AWS architecture exams are going to be a better starting place. Because you’re going to understand the environment. You can't secure it if you don’t understand it. That’s where we run into most of the problems around cloud security: when people take an old approach and try to apply it in the cloud. Start with learning to build well, then once you have that locked in, go for the security specialization certification.
