Let’s move our ops to the cloud they said. It will be easy, fun, and “secure.”
Everything is safe, right? The Cloud is certified for every compliance, ever drafted. It must be safe. So what happens when windows get left open on your cloud? How about doors with old rusty locks?
This webcast covers a disclosure first made to AWS support in December of 2018. The conversation was quiet for a while. BHIS re-submitted the disclosure and worked with AWS Security Operations for the next few months to share a finding/vulnerability/exposure, whathaveyou.
Sadly, the nature of the exposure has left many doors open. Those doors lead to virtual private clouds across the globe.
This is one of the scarier webcasts we’ve been a part of, and for that, we’d like to say we shared everything we could, including a blog write-up that explains in all the gory detail how risky Hue / Hadoop / Spark and the Apache big data clusters can be to an organization. It was originally drafted as “Breaking the Internet” – but this was toned down a bit to “Securing the Cloud.”
On the webcast, we talk a bit about the nature of open source solutions and the risks they present. We talk a bit about the cloud and the risks it presents. A lot of AWS specific service language is used and hopefully explained in a meaningful way. And, we offer up the Shodan query that identifies the possibly open doors. Oh, we go ahead and demo the nature of the exposure as well (shells).
Also, this webcast serves as a starting point for anyone trying to get started in researching cloud security issues.
