Protecting Against the Unpatched Kubernetes Vulnerability (CVE-2020-8554)

CVE-2020-8554 is a vulnerability that allows Kubernetes Services to intercept cluster traffic to any IP address. Users who can manage services can exploit the vulnerability to carry out man-in-the-middle (MITM) attacks against pods and nodes in the cluster. All Kubernetes versions including the latest release (v1.20) are vulnerable to this attack. If your cluster is multi-tenant, or allows unprivileged users to create and update services, you are impacted.

Kubernetes Observability Challenges: The Need for an AI-Driven Solution

Kubernetes provides abstraction and simplicity with a declarative model to program complex deployments. However, this abstraction and simplicity create complexity when debugging microservices in this abstract layer. The following four vectors make it challenging to troubleshoot microservices.

Calico Enterprise Multi Cluster Management - Federated Identity and Services

Managing multiple Kubernetes clusters can become time consuming and complex. Calico Enterprise can help with built in multi-cluster management capabilities to simplify deployment and ongoing operations, including securing interactions between the clusters, and providing cross-cluster service discovery.

Best Practices for Kubernetes Monitoring

Kubernetes, also known as K8s, is a container-orchestration platform for automating deployment, scaling, and operations of applications running inside the containers across clusters of hosts. Google open-sourced the Kubernetes project in 2014. According to a recent CNCF survey, Kubernetes is the most popular container management tool among large enterprises, used by 83% of respondents. Containers are a good way to bundle and run applications.
