When we first published this blog post in 2017, the technology landscape for containers was quite different than it is today. Over the past two years, we have seen significant changes take place that affected, and continue to affect how Containers are adopted. As we enter the new decade, we want to recap the changes and developments that we saw and offer our view of where we believe Containers are
Tracee, by Aqua Security, is an open source, lightweight, and easy to use container and system tracing utility. Tracee allows you to trace events that were generated within containers only, without needing to filter out other system processes. Tracee is powered by eBPF technology. eBPF enables users to run programs that help with the observability of the system. In this blog post I will discuss wh
The premise of DevSecOps is that in the Software Development Life Cycle (SDLC), each member is responsible for security. This unifies the operations and development teams in terms of security operations. DevSecOps’ goal is to add security to each step of the development process by integrating security controls and processes as early as possible in the DevOps process. In this post, I’ll describe ho
This week at Velocity Berlin, I’ll be giving a talk called A Beginner’s Guide to eBPF. To coincide with it, we’re opening up a new Aqua Security open source project called Tracee, which uses eBPF to trace events in containers. This isn’t something that most developers need to do on a day-to-day basis, but for those of us interested in the details of implementing container security, this can be a h
Kubernetes has many moving parts, and sometimes combining them in certain ways can create unexpected security flaws. In this post you’ll see how a pod running as root and with a mount point to the node’s /var/log directory can expose the entire contents of its host filesystem to any user who has access to its logs. We’ll also talk about your options to mitigate this issue in your cluster. Understa
In this post I’ll describe how an attacker, who manages to run malicious code on a cluster can, with no special permissive permissions, successfully spoof DNS responses to all the applications running on the cluster, and from there execute a MITM (Man In The Middle) on all network traffic of pods. Before we get into the attack scenario, let’s understand how Kubernetes intra-node networking works.
Trivy Vulnerability Scanner Joins the Aqua Open-source Family If you’re interested in container image vulnerability scanning, there’s a good chance that you have come across the Trivy open source scanning tool. This project has been receiving rave reviews for its ease-of-use, as well as its comprehensive vulnerability tracking across both OS packages and language-specific dependencies. I’m absolut
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 side-car container. But before we get into that - having spent some more time with it
Good news for those of you running container workloads on GCP - we now provide a nice integration with Google's Cloud Security Command Center. The Cloud SCC provides a centralized, single-pane-of-glass view of all security data for GCP applications, and providing actionable insights. It includes things like access control monitoring, asset inventory, vulnerability assessment data, anomaly detectio
Kubernetes 1.10 was officially released recently, with many new enhancements and improvements. This version of Kubernetes, which is lighter on the security side compared to the recent 1.9 and 1.8 releases that were very security focused, offers several new worthy security related features. Limit node access to the API In 1.10 you can limit node access to API server using the NodeRestriction admis
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 1.8 and 1.9, including many security-related constructs that make it easier to manage
Like many of you working in Docker-space, over time I’ve come across a ton of third-party tools that improve management, cleanup, orchestration, development and other container processes. I’ve compiled a list of (I think) some of the lesser-known tools that I have found to be particularly useful and easy to use, and sometimes better than equivalent, more well-known tools. Orchestration You’ve prob
