Applying policy as code in the modern cloud-ready enterprise: Graeme Hay, Morgan Stanley

Jun 11, 2021 By Tigera In Tigera
Join us as we look at the advantages, but also the practical challenges, of applying modern, policy-as-code ("PaC") approaches in a modern cloud-ready enterprise. This talk will show how Morgan Stanley is drawing upon years of experience in its own proprietary implementation of PaC in its approach to embracing today's ideas. We will look at a diverse set of considerations from GitOps as a method to applying PaC in modern software development and deployment to enforcement of best practices and compliance in the Cloud.

CVE-2021-31440: Kubernetes container escape using eBPF

Jun 9, 2021 By Manoj Ahuje In Tigera

In a recent post by ZDI, researchers found an out-of-bounds access flaw (CVE-2021-31440) in the Linux kernel’s (5.11.15) implementation of the eBPF code verifier: an incorrect register bounds calculation occurs while checking unsigned 32-bit instructions in an eBPF program. The flaw can be leveraged to escalate privileges and execute arbitrary code in the context of the kernel.

Dynamic Service Graph | Tigera - Long

May 4, 2021 By Tigera In Tigera
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

May 4, 2021 By Tigera In Tigera
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?
