Privileged pod escalations in Kubernetes and GKE (Google Online Security Blog)
Posted by GKE and Anthos Platform Security Teams At the KubeCon EU 2022 conference in Valencia, security researchers from Palo Alto Networks presented research findings on “trampoline pods”—pods with an elevated set of privileges required to do their job, but that could conceivably be used as a jumping off point to gain escalated privileges. The research mentions GKE, including how developers should look at the privileged pod problem today, what the GKE team is doing to minimize the use of privileged pods, and actions GKE users can take to protect their clusters. Privileged pods within the context of GKE securityWhile privileged pods can pose a security issue, it’s important to look at them within the overall context of GKE security. To use a privileged pod as a “trampoline” in GKE,…
