Properly testing your virtual infrastructure has been an issue almost since there were virtual VMs and AWS. Lately, the tool sets have gotten better. Part of the problem is that to adequately test your AWS installation, you need to know a lot about how it is constructed. CPUs can come and go, and storage blocks are created and destroyed in a blink of an eye. And as the number of AWS S3 data leaks rises, there have to better ways to protect things. Rhino Security and Amazon both offer tools to improve visibility into your AWS cloud environments, making it easier to find configuration errors and vulnerabilities.I write about Pacu and CloudGoat tools as well as various AWS services to test your VMs in my article from CSOonline here.
