New kubernetes vulnerability

Hey there,

Did you know of the new vulnerability that has been discovered within the k8s API?
This flaw is centered around the parsing of YAML manifests by the Kubernetes API server. During this process, the API server is open to potential Denial of Service (DoS) attacks. Read more in the Community section below.

Kubernetes ‘Billion Laughs’ Vulnerability Is No Laughing Matter

A new vulnerability has been discovered within the Kubernetes API. This flaw is centered around the parsing of YAML manifests by the Kubernetes API server. During this process, the API server is open to potential Denial of Service (DoS) attacks. The issue (CVE-2019-11253 — which has yet to have any details fleshed out on the page) has been labeled a “Billion Laughs” attack because it targets the parsers to carry out the attack.


 Top 5 Container Security Tools You Should Already Be Using

Containers have been one of the hottest trends in the software industry in recent years as more organizations turn to them to build, test, and deploy faster without the frictions that can come from changing environments. However, while tools like Kubernetes and Container Registries have become household names for developers because these tools make it easier to develop and deploy containers, many are still catching up on the need to integrate container security tools in order to secure their containerized application throughout the container lifecycle.


Michael Dell: Kubernetes On VMware vSphere Coming ‘Very, Very Soon’

“We’re putting Kubernetes right into vSphere. We showed that on stage at VMWorld and gave demos of it -- that’s coming very, very soon to the 600,000 vSphere customers that we have around the world,” said Dell in an interview with CRN. “It’s incredibly powerful to be able to manage virtual machines and Kubernetes clusters all from the same console and framework that all these customers are already use too.”


Kubernetes is Winning the Multi-Cloud War

Most enterprise organizations are multi-cloud. So says our own research, as well as just about every other industry report I can find. In fact, I find consistently that less than 20% of organizations are shunning public cloud in general. Given the nearly ubiquitous use of SaaS to supply commoditized business functions (CRM, productivity, SFA, communications) it seems inarguable that organizations make use of multiple cloud properties to host a portion of their application portfolios.
