Mayhem, the Machine That Finds Software Vulnerabilities, Then Patches Them

Back in 2011, when the venture capitalist Marc Andreessen said that “software is eating the world,” it was still a fresh idea. Now it’s obvious that software permeates our lives. From complex electronics like medical devices and autonomous vehicles to simple objects like Internet-connected lightbulbs and thermometers, we’re surrounded by software. And that means we’re […]

Can Kubernetes Keep a Secret? It all depends what tool you’re using

At Soluto, we have super-devs who have full ownership: from writing code to deploying it to monitoring. When we made the shift to Kubernetes, we wanted to keep our devs independent and put a lot of effort into allowing them to create services rapidly. It all worked like a charm – until they had to […]

Docker and Kubernetes in high security environments

This is brief summary of parts of my master’s thesis and the conclusions to draw from it. This medium-story focuses on containerized application isolation. The thesis also covers segmentation of cluster networks in Kubernetes which is not discussed in this story.You can read my full thesis here; it’s available through open access:Container Orchestration in Security […]

CVE-2018-18264 Privilege escalation through Kubernetes dashboard

A recently disclosed vulnerability in Kubernetes dashboard (CVE-2018-18264) exposes secrets to unauthenticated users. In this blog post we’ll explore some key takeaways regarding monitoring privilege escalation on Kubernetes. The Kubernetes dashboard is a web based user interface that allows users to manage applications and resources within the cluster. This service has a login functionality starting […]

New AWS services launch with HIPAA, PCI, ISO, and SOC

Our security culture is one of the things that sets AWS apart. Security is job zero — it is the foundation for all AWS employees and impacts the work we do every day, across the company. And that’s reflected in our services, which undergo exacting internal and external security reviews before being released. From there, […]

Running Kubernetes in the Federal Government

Tackling security compliance is a long and challenging process for agencies, systems integrators, and vendors trying to launch new information systems in the federal government. Each new information system must go through the Risk Management Framework (RMF) created by the National Institute of Standards and Technology (NIST) in order to obtain authority to operate (ATO). […]

DNS over TLS: Encrypting DNS end-to-end

As a first step toward encrypting the last portion of internet traffic that has historically been cleartext, we have partnered with Cloudflare DNS on a pilot project. This pilot takes advantage of the benefits of Transport Layer Security (TLS) — a widely adopted and proven mechanism for providing authentication and confidentiality between two parties over […]

Moving from Kube2Iam to Kiam

At Ibotta, we chose kube2iam to assign AWS IAM Roles to containers running in our Kubernetes cluster. Lately, we’ve run into some issues with it—specifically when running a job that scores all of our service repos. This spins up a number of pods in parallel and has often failed to correctly access roles. After further […]

Kubernetes’ first major security hole discovered

Kubernetes has become the most popular cloud container orchestration system by far, so it was only a matter of time until its first major security hole was discovered. And the bug, CVE-2018-1002105, aka the Kubernetes privilege escalation flaw, is a doozy. It’s a CVSS 9.8 critical security hole. CVSS 9.8 critical security hole. With a […]
