On Oct 21st, the Kubernetes Security Response Committee issued an alert that a new high severity vulnerability was discovered in Kubernetes with respect to the ingress-nginx - CVE-2021-25742.

Containers have changed how applications are developed and deployed, with Kubernetes ascending as the de facto means of orchestrating containers, speeding development, and increasing scalability. Modern application workloads with microservices and containers eventually need to communicate with other applications or services that reside on public or private clouds outside the Kubernetes cluster. However, securely controlling granular access between these environments continues to be a challenge.

The ISO 27001 certification can make a difference when your business is tied with deploying cloud-native applications. Providing relevance and credibility in front of potential customers will show that your company takes security seriously, ensuring the client’s trust. We previously covered other compliance frameworks in our blog, like GDPR, HIPAA, NIST, and SOC 2. Those frameworks also show a strong commitment to security best practices.

Congratulations to the Kubespray team on the release of 2.17! This release brings support for two of the newer features in Calico: support for the eBPF data plane, and also for WireGuard encryption. Let’s dive into configuring Kubespray to enable these new features.

A problem that is often discussed in the context of policy-as-code is how to get more people other than developers involved in policy authoring.
