How to See Events in the Tetragon CLI ll Swift Start Guide

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.

Getting started with eBPF

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.

LabsTetragon

Getting Started with Tetragon

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!

Cilium Egress Gateway

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.

Cilium Hubble: Redact Sensitive Information From Network Observability Flows

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.

Cilium Multi-Network

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.

Migrating from Calico

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.

BGP on Cilium

Learn how to connect your Kubernetes Clusters with your on-premises network using BGP. 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 running BGP is needed. Cilium offers native support for BGP, exposing Kubernetes to the outside and all the while simplifying users’ deployments.
