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 …
Infrastructure protection, sandboxed containers, MicroVM hypervisors– these are interchangeable terms describing emerging technologies to isolate micro-services from their underlying infrastructure. These isolation technologies aim to protect the underlying host that runs containers and functions against malicious …
Earlier this week, a severe vulnerability in Kubernetes (CVE-2018-1002105) was disclosed that allows an unauthenticated user to perform privilege escalation and gain full admin privileges on a cluster. The CVE was given the high severity score of 9.8 (out of 10) and it affects all Kubernetes versions from 1.0 …
Gartner recently released a Technical Professional Advice report titled Container Security -- From Image Analysis to Network Segmentation, Options Are Maturing* (by Joerg Fritsch and Michael Isbitski, 28 August 2018), with a detailed analysis of the space, including open source tools and commercial solutions.

One of the challenges organizations have in using cloud-native technologies is in figuring out how compliance requirements translate into actionable control points. Most regulations predate containers and serverless technologies and don’t have specific articles governing the use of such technologies.
We recently …
Recently, IBM researchers weighed in on container isolation, having developed an algorithm for measuring how well it works, and reached the conclusion that "a Docker container with a well crafted seccomp profile (which blocks unexpected system calls) provides roughly equivalent security to a hypervisor."
A few months ago we launched the Aqua MicroEnforcer, the first solution for providing runtime protection to a container running in Containers-as-a-Service platforms like AWS Fargate or Azure Container Instances. The mechanism I wrote about at the time involved building a protected version of a container image being …
Back in March we announced Aqua MicroEnforcer, a new deployment technology that enabled us to secure runtime workload running on AWS Fargate and Azure Container Instances. Since then we’ve seen a lot of interest from customers who see these services not only as a way to deploy containers on demand for spillover …
Since the second half of 2017, Kubernetes has been gaining momentum in adoption as well as in its ecosystem support. We see more and more enterprises choosing Kubernetes for the orchestration of their cloud-native deployments. This is in no small part thanks to the many enterprise-grade features added in versions …
A few months ago I was lucky enough to get my hands on Fargate when it was in preview in the run-up to AWS re:invent. It was immediately clear that it’s a pretty cool concept, and that it presents a new challenge for security solutions like Aqua, because of the lack of a “host” entity on which you can deploy your …
