Tetragon
eBPF runtime security tool for Kubernetes and Linux that provides process, syscall, file, and network observability with in-kernel enforcement.
Technical Architecture & Overview
Tetragon is an open-source runtime security tool that uses eBPF to observe and enforce policy on process execution, system calls, file access, and network activity in Linux and Kubernetes environments. It is a sub-project of Cilium, which is a CNCF graduated project.
Targeted Technical Use Cases
Monitoring and enforcing runtime behavior in Kubernetes clusters and Linux servers.
Evaluation & Trade-offs
Core Strengths
- +Kernel-level observation and enforcement with low overhead.
- +Kubernetes-aware metadata for pod, namespace, and workload context.
- +Supports custom tracing policies for threat detection and prevention.
Trade-Offs & Limitations
- -Requires modern Linux kernels with eBPF and BTF support.
- -Policy authoring and event interpretation need eBPF and security expertise.
Defensive Security Application
Blocking unauthorized process execution, data exfiltration, and privilege escalation in container workloads.
