The runC Vulnerability - A Deep Dive on Protecting Yourself

The runC Vulnerability - A Deep Dive on Protecting Yourself

A vulnerability in runC, which allows an attacker to gain host-level code execution by breaking out of a running container, was discovered and reported by Adam Iwaniuk and Borys Poplawski in early January and published as CVE-2019-5736 on 11 February 2019. This vulnerability is highly significant in that it: enables container isolation breakout with minimal interaction from an authorized host user; typically allows an attacker to obtain root privileges on the host; negatively impacts most container environments because many containers run with default Docker security settings and default user (UID 0); and affects runC, the most commonly used low-level container runtime in Docker and Kubernetes environments.

StackRox is All In on Kubernetes – and It Makes Your Container Security Better

StackRox is All In on Kubernetes – and It Makes Your Container Security Better

In a news release today, we detailed new capabilities in the latest version of the StackRox Kubernetes Security Platform that enable better visibility, more nuanced risk profiling, and more streamlined network policy enforcement. In every case, these new features derive directly from our deep integrations with Kubernetes. About a year ago, we faced a difficult decision – continue our support of a broad array of orchestrator platforms or narrow our focus to supporting just Kubernetes.

StackRox – Putting the Customer at the Center of Kubernetes Security

When we officially launched the StackRox Kubernetes Security Platform about 18 months ago, we highlighted that microservices, containers, and Kubernetes were the next stage in the evolution of application development in the cloud-native stack. While DevOps embraced microservices and its advantages in delivering unprecedented speed, efficiency, and portability, security teams were frequently left in the dark or brought in a little too late. Today, security teams are proactively working with DevOps to ensure that their organization’s security and compliance requirements are adequately addressed before new apps go live.

Must-Have Capabilities When Evaluating Container Security Solutions

Must-Have Capabilities When Evaluating Container Security Solutions

More and more organizations are transforming their businesses by embracing DevOps principles, microservice design patterns, and container and orchestrator technologies such as Docker and Kubernetes. While security teams have the same mission regardless of the technology stack in use – keep the bad guys out and find and stop them if they do break in – the tools and tactics security staff employ must change to accommodate this infrastructure shift.

Top 5 Container and Kubernetes Security Posts of 2018

Top 5 Container and Kubernetes Security Posts of 2018

The year 2018 was a watershed for containers, container security, and Kubernetes. Tesla got hacked, the most critical Kubernetes vulnerability to date was discovered, IBM bought RedHat for $34 billion (in large part for OpenShift), VMware bought Heptio for more than $500 million, and investors poured money into container technology startups at an ever-increasing pace. The Following five blog articles capture and distill the big picture trends in container adoption and Kubernetes security in 2018.

6 Container Security Best Practices You Should Be Following

6 Container Security Best Practices You Should Be Following

The advent of containers has not only made application development and deployment simpler, scalable, and portable but also enabled more inherent security compared to traditional application development technologies and methodologies. You can leverage many inherent security advantages as you move applications to containers – even if you’re porting a monolithic app and not yet adopting microservices. With containers, you can: Minimize your attack surface much more effectively than is possible with a virtual machine (VM) or bare metal server by reducing functionality in the container to the bare minimum set of processes, image components, filesystem access, and other settings.

Survey Says … Security Tops the List of Container Strategy Concerns

Survey Says … Security Tops the List of Container Strategy Concerns

This week StackRox launched the industry’s first ever State of Container Security report. To compile the findings, we surveyed more than 230 IT leaders across operations and security roles. Some responses came as no surprise – the dominance of Docker and Kubernetes, for example, or the breadth of industries using containers to accelerate application roll out. But many results did surprise us – including the extent to which security leads the list of concerns about companies’ container strategies.

Today we posted the news that we’ve adopted StackRox to secure our environment. I wanted to share a bit about our thought process and results in hopes of helping others like us. Security is difficult to manage at every level of technology development, from building a simple web app to running enormous platforms like the tech giants manage — recent tech headlines just prove this point. Like other early-stage SaaS startups, we here at Mux face the combined challenges of having limited resources, a relatively large technology footprint, and the obvious focus on building strong product features.

The StackRox Kubernetes Security Platform Today we announced that we will release an updated version of the StackRox Kubernetes Security Platform later this month. As we continue to lead the industry in container security innovation, we are excited to detail our new capabilities. Over the past nine months or so since we started shipping our software, we have seen a few consistent patterns among our enterprise customers. These organizations remain focused on reducing the attack surface across their container environments, and addressing orchestrator-based threats are a key part of that initiative.

Gartner on Delivering DevOps Risk-Prioritized Vulnerability Guidance

Gartner on Delivering DevOps Risk-Prioritized Vulnerability Guidance

We recently highlighted Gartner’s advice to “shift right” with security, to avoid burdening developers from a security standpoint. Gartner analyst Dale Gardner continued that theme with this opening slide to his talk advising teams to “Fix What Matters” in the area of vulnerabilities. Dale noted that we excel at finding vulnerabilities, leading to the garbage heap analogy. “We end up with this graveyard of multiple vulnerability reports,” Dale observed. Bringing this world view into container security doesn’t make this problem any easier – indeed, now you have more “things” to secure.

Detecting Docker Exploits and Vulnerabilities - Your How-to Guide

Detecting Docker Exploits and Vulnerabilities - Your How-to Guide

There has never been a better time to be a DevOps engineer. Compared to traditional web stacks, containerization has dramatically streamlined the task of deploying web services such as databases, key/value stores, and servers. Furthermore, container orchestration tools, like Google’s Kubernetes and Docker Swarm, enable organizations to automate the deployment and management of these containerized applications. But the tools that make life easier and more efficient for engineers can also be a gift to an attacker.
