Mapping Risks and Threats in Kubernetes to the MITRE ATT&CK Framework

In April, MITRE published the ATT&CK matrix for Containers covering adversarial techniques that target container technologies. At Aqua, we were proud to support this effort by sharing our knowledge and helping refine and extend the matrix. As for the risks in Kubernetes, Microsoft created a framework for Azure-based environments (AKS), but what about vanilla K8s? …

Improving Your Kubernetes Authorization: Don’t Use system:masters

When you’re operating Kubernetes clusters, an important area of focus is in ensuring your authorization model is correct and provides users with the least privileges needed for them to carry out their roles. As such, blanket cluster-admin privileges should never be used and in particular the in-built system:masters group should be avoided.

Why You Shouldn’t Use Config Maps to Store Sensitive Data in K8s

One of the challenges of managing containerized environments is how to store sensitive information that’s needed for the operation of the applications running in those environments. Kubernetes provides a built-in secrets object type, but a common comment about them is that, from a technical standpoint, they’re just the same as other object types like Config …
