After installing Tetragon, generate events in the Tetragon CLI and observe process and socket events. In our case, we are going to observe tcp_connect, tcp_close, and kernel functions to track when a TCP connection opens and closes respectively.

After installing Tetragon, apply a TracingPolicy using Tetragon. A TracingPolicy is a user-configurable Kubernetes custom resource definition (CRD) that allows you to trace arbitrary events in the kernel and define actions to take on match.

How to install Tetragon, the eBPF based security observability tool on Kubernetes. Follow along on the Tetragon installation guide to install the Cilium/Tetragon helm chart, download Tetragon, and verify Tetragon has successfully rolled out.

eBPF is the new standard to program Linux kernel capabilities in a safe and efficient manner without requiring to change kernel source code or loading kernel modules. It has enabled a new generation of high performance tooling to be developed covering networking, security, and observability use cases. The best way to learn about eBPF is to read the book “What is eBPF” by Liz Rice. And the best way to have your first experience with eBPF programming is to walk through this lab, which takes the opensnoop example out of the book and teaches you to handle an eBPF tool, watch it loading its components and even add your own tracing into the source eBPF code.

Security Observability is a new paradigm that utilizes eBPF, a Linux kernel technology, to allow Security and DevOps teams, SREs, Cloud Engineers, and Solution Architects to gain real-time visibility into Kubernetes and helps to secure your production environment with Tetragon. Tetragon is an open source Security Observability and Runtime Enforcement tool from the makers of Cilium. It captures different process and network event types through a user-supplied configuration to enable security observability on arbitrary hook points in the kernel; then translates these events into actionable signals for a Security Team. The best way to learn about Security Observability and Cilium Tetragon is to read the book “Security Observability with eBPF” by Jed Salazar and Natalia Reka Ivanko. And the best way to have your first experience with Tetragon is to walk through this lab, which takes the Real World Attack example out of the book and teaches you how to detect a container escape step by step!

Kubernetes changes the way we think about networking. In an ideal Kubernetes world, the network would be entirely flat and all routing and security between the applications would be controlled by the Pod network, using Network Policies. In many Enterprise environments, though, the applications hosted on Kubernetes need to communicate with workloads living outside the Kubernetes cluster, which are subject to connectivity constraints and security enforcement. Because of the nature of these networks, traditional firewalling usually relies on static IP addresses (or at least IP ranges). This can make it difficult to integrate a Kubernetes cluster, which has a varying —and at times dynamic— number of nodes into such a network. Cilium’s Egress Gateway feature changes this, by allowing you to specify which nodes should be used by a pod in order to reach the outside world.

Isovalent's VP of Customer Success, Toufic Arabi, outlines what prospective customers should expect when onboarding with Isovalent.

Cilium and Hubble give you deep visibility into the network flows across your cloud-native platform and can inspect and show you meaningful data between the transactions between services, such as URL parameters. Sometimes this data can be classified as sensitive, or even potentially unnecessary when storing the network flows. In Cilium 1.15, the Hubble Redact features provide the ability to sanitize sensitive information from Layer 7 data flows captured by Hubble.

In this video, Isovalent's Head of Global Cloud Alliances, Jeff Clawson, break down Isovalent's payment model and the types of businesses that it's implemented to help with the most.

Kubernetes is built on the premise that a Pod should belong to a single network. While this approach may work for the majority of use cases, enterprise and telco often require a more sophisticated and flexible networking model. There are many use cases where a Pod may require attachments to multiple networks with different properties via different interfaces. With Cilium Multi-Networking, available in Isovalent Enterprise for Cilium, you can connect your Pod to multiple networks, without having to compromise on security and observability.

As Kubernetes becomes more pervasive in on- premise environments, users increasingly have both traditional applications and Cloud Native applications in their environments. In order to connect them together and allow outside access, a mechanism to integrate Kubernetes and the existing network infrastructure is needed. Cilium offers native support for BGP , exposing Kubernetes applications to the existing data center, without the need to install yet another tool.

Migrating to Cilium from another CNI is a very common task. But how do we minimize the impact during the migration? How do we ensure pods on the legacy CNI can still communicate to Cilium-managed during pods during the migration? How do we execute the migration safely, while avoiding a overly complex approach or using a separate tool such as Multus? With the use of the new Cilium CRD CiliumNodeConfig, running clusters can be migrated on a node-by-node basis, without disrupting existing traffic or requiring a complete cluster outage or rebuild. In this lab, you will migrate your cluster from Calico to Cilium.
