Dynamic Service Graph | Tigera - Long

Downtime is expensive and applications are a challenge to troubleshoot across a dynamic, distributed environment consisting of Kubernetes clusters. While development teams and service owners typically understand the microservices they are deploying, it’s often difficult to get a complete, shared view of dependencies and how all the services are communicating with each other across a cluster. Limited observability makes it extremely difficult to troubleshoot end-to-end connectivity issues which can impact application deployment.

Application Layer Observability | Tigera - Long

The majority of operational problems inherent to deploying microservices in a distributed architecture are linked to two areas: networking and observability. At the application layer (Layer 7), the need to understand all aspects associated with service-to-service communication within the cluster becomes paramount. Service-to-service network traffic at this layer is often using HTTP. DevOps teams struggle with these questions: Where is monitoring needed? How can I understand the impact of issues and effectively troubleshoot? And how can I effectively protect application-layer data?

DNS Dashboard | Tigera - Long

While it’s an essential part of Kubernetes, DNS is also a common source of outages and issues in Kubernetes clusters. Debugging and troubleshooting DNS issues in Kubernetes environments is not a trivial task given the limited amount of information Kubernetes provides for DNS queries. The DNS Dashboard in Calico Enterprise and Calico CLoud helps Kubernetes teams more quickly confirm or eliminate DNS as the root cause for microservice and application connectivity issues.

How Calico Cloud's runtime defense mitigates Kubernetes MITM vulnerability CVE-2020-8554

Since the release of CVE-2020-8554 on GitHub this past December, the vulnerability has received widespread attention from industry media and the cloud security community. This man-in-the-middle (MITM) vulnerability affects Kubernetes pods and underlying hosts, and all Kubernetes versions—including future releases—are vulnerable. Despite this, there is currently no patch for the issue.

TeamTNT: Latest TTPs targeting Kubernetes (Q1-2021)

In April 2020, MalwareHunterTeam found a number of suspicious files in an open directory and posted about them in a series of tweets. Trend Micro later confirmed that these files were part of the first cryptojacking malware by TeamTNT, a cybercrime group that specializes in attacking the cloud—typically using a malicious Docker image—and has proven itself to be both resourceful and creative.

Honeypods: Applying a Traditional Blue Team Technique to Kubernetes

The use of honeypots in an IT network is a well-known technique to detect bad actors within your network and gain insight into what they are doing. By exposing simulated or intentionally vulnerable applications in your network and monitoring for access, they act as a canary to notify the blue team of the intrusion and stall the attacker’s progress from reaching actual sensitive applications and data.

Tigera to Provide Native Kubernetes Support for Mixed Windows/Linux Workloads on Microsoft Azure

Tigera, in collaboration with Microsoft, is thrilled to announce the public preview of Calico for Windows on Azure Kubernetes Service (AKS). While Calico has been available for self-managed Kubernetes workloads on Azure since 2018, many organizations are migrating their .NET and Windows workloads to the managed Kubernetes environment offered by AKS.
