Last June, Tigera announced a first for Kubernetes: supporting open-source WireGuard for encrypting data in transit within your cluster. We never like to sit still, so we have been working hard on some exciting new features for this technology, the first of which is support for WireGuard on AKS using the Azure CNI. First a short recap about what WireGuard is, and how we use it in Calico.
In 2014, Kubernetes surfaced from work at Google and quickly became the de facto standard for container management and orchestration. Despite its silicon valley origins, it became one of the most impactful open-source projects in the history of computing. Today, the Cloud Native Computing Foundation (CNCF) maintains Kubernetes with many private companies and independent open-source developers.
Cloud-native transformations come with many security and troubleshooting challenges. Real-time intrusion detection and the prevention of continuously evolving threats is challenging for cloud-native applications in Kubernetes. Due to the ephemeral nature of pods, it is difficult to determine source or destination endpoints and limit their blast radius. Traditional perimeter-based firewalls are not ideal fit for Kubernetes and containers.
Malware is continuously mutating, targeting new services and platforms. The Sysdig Security Research team has identified the famous Muhstik Botnet with new behavior, attacking a Kubernetes Pod with the plan to control the Pod and mine cryptocurrency. A WordPress Kubernetes Pod was compromised by the Muhstik worm and added to the botnet. On the Pod has been deployed and executed various types of crypto miners, like xmra64andxmrig64.
Discover how to get started with Falco to overcome the challenges of implementing runtime security for cloud-native workloads. If you are adopting containers and cloud, you are probably enjoying benefits like automated deployments and easier scalability. However, you may also find that when it comes to security, this is a whole new world with new rules, and traditional security tools struggle to keep up. As a new paradigm, cloud-native environments need new cloud-native tools.
From reading many Python Docker container blogs, we’ve found that the majority of posts provide examples of how to containerize a Python application independent of its framework (Django, Flask, Falcon, etc.). For example, you might see something like this: With this Dockerfile, we can build and run a Python Flask application: Two simple steps and it works just fine, right?
