A key element in building secure containerized applications is to ensure that the base image that you use is well-maintained and secure. A common piece of advice is to use the Docker Official Images for this purpose. However, our research reveals that you need to be careful when using these images, as some are no …

While Docker has become synonymous with containers, various container tools and platforms have emerged to make the process of developing and running containers more efficient. Still, a lot of the same principles around Docker security apply for protecting container-based applications built with other tools as well. We compiled 20 essential Docker security best practices into …

One of the challenges of container security is ensuring that the image you’re getting is exactly what you expect it to be. Both from a security and consistency perspective, it’s important to ensure there are no surprises in what you’re downloading. Docker image tags, whilst convenient, can’t always be relied on to point to a …

Docker clients can communicate with the daemon either locally, via a unix socket, or over a network via a TCP socket. Aqua’s research team discovered an interesting attack vector running on top of an unsecured Docker socket API. Instead of running a malicious Docker image, the attacker changes the traditional entry-point to take control over …

A new vulnerability that impacts Alpine Docker images was published last week. The vulnerability is due to the ‘root’ user password which is set, by default, to NULL on Alpine Docker images from version 3.3 or higher.

A few days ago, Docker discovered that a database holding the credentials of some 190,000 Docker Hub accounts was exposed to unauthorized access (about 5% of all Docker Hub accounts). We’ve been getting questions from customers on this, so I wanted to set the record straight on what we know and what we recommend doing.

Yesterday it was disclosed that a new high severity (CVSS score 7.2) vulnerability (CVE-2019-5736) was found in runc, that allows an attacker to potentially compromise the container host. Patches are already available from most providers (see below). Aqua customers can also prevent this vulnerability from being exploited by applying the appropriate runtime policies. 

In a previous post, we explored six tools for storing data for Docker containers. Another challenge in container environments is getting containers to network in a consistent and secure manner – especially as container workloads may appear on different hosts as applications scale out, then disappear when they’re not needed. On a single host, Docker …

Continuous integration and continuous delivery (CI/CD) are two of the biggest trends in software development. As companies move to release higher quality software at a faster pace, developers and engineers need new approaches to building, testing, and delivering products. As a result, many companies are turning to Docker to build, test, and deploy their applications.

This isn’t a story about a Docker vulnerability; it’s a story about how hackers are looking for unsecured Docker deployments where they can mine cryptocurrency. You shouldn’t leave your Docker daemon unsecured  any more than you would leave your mail server unsecured. We’ve heard many accounts of attempted (sometimes successful) cryptocurrency mining attacks on container …

Storage has been a hot topic for as long as containers have been around. According to a survey by Portworx, 26% of IT pros cite persistent storage as the most difficult challenge in adopting containers, and 44% blame inadequate tools as the main reason. Although containers are stateless by design, the need to store data …

From a “humble” $762 million in 2016, containers are predicted to grow faster than any other technology this year (as well as the next) and are on the way to become a $2.7B industry by 2020.
