The Kubernetes Network Analyzer

Through Scalable & Secure Traffic Capture

Kubeshark is an API Traffic Analyzer for Kubernetes providing real-time, protocol-level visibility into Kubernetes’ internal network, capturing, dissecting and monitoring all traffic and payloads going in, out and across containers, pods, nodes and clusters.

Think TCPDump and Wireshark re-invented for Kubernetes.

Kubeshark Use-cases

Visit the following sections to read more about use-cases, Kubeshark can be helpful with:

• Investigation & API Debugging
• Observability & Telemetry
• Cloud Forensics
• Detection Engineering

Network Analysis

Kubeshark can sniff parts or all OSI L4 (TCP and UDP) traffic in your cluster, record it into PCAP files and dissect the following application layer protocols:

• HTTP/1.0
• HTTP/1.1
• HTTP/2
• AMQP
• Apache Kafka
• Redis
• DNS

Kubeshark recognizes gRPC over HTTP/2, GraphQL over HTTP/1.1 and GraphQL over HTTP/2.

Kubeshark uses extended BPF (eBPF) to trace function calls in both the kernel space and the user space.

Kubeshark can sniff the encrypted traffic (TLS) in your cluster using eBPF without actually doing decryption. In fact, it hooks into entry and exit points in certain functions inside the OpenSSL library and Go’s crypto/tls package.

Kubeshark can recognize service mesh solutions like Istio, Linkerd and other service mesh solutions that use Envoy Proxy under the hood.

Actionable Automation, Scripts & L4/L7 Hooks

With a combination of a scripting language, hooks, helpers and jobs, Kubeshark can detect suspicious network behaviors and trigger actions supported by the available integrations (e.g Slack, AWS S3, InfluxDB, Elasticsearch and more).
