eBPF telemetry for workloads: what IAM and NHI teams miss

TL;DR: Kernel tracepoints can be carried through eBPF, OpenTelemetry, and Prometheus to turn raw file-creation events into labeled metrics, according to Riptides. But the deeper lesson is that kernel-level telemetry only helps if identity and workload posture are already governed, and the real gap is not visibility alone, but whether workloads have disciplined, reviewable identity boundaries.

Questions worth separating out

Q: How should security teams use kernel telemetry in workload identity programmes?

A: Use kernel telemetry as evidence, not as a control.

Q: Why does observability not replace workload access governance?

A: Observability tells you that an event happened.

Q: How do organisations know if telemetry is actually improving identity control?

A: Look for evidence that telemetry is driving decisions, not just dashboards.

Practitioner guidance

• Map kernel telemetry to workload identities Bind tracepoint output to a current inventory of service accounts, workloads, and owning teams so each metric can be traced back to an accountable identity.
• Validate the event path before operational use Test architecture-specific handling, kernel-version assumptions, and ring-buffer behaviour so the telemetry you depend on is stable across the environments you run.
• Separate observation from enforcement Use kernel metrics as evidence for review and detection, but keep authorization, lifecycle changes, and access decisions in governed identity controls such as policy and approvals.

What's in the full article

Riptides' full post covers the operational detail this post intentionally leaves for the source:

• Kernel module code and the exact kretprobe wiring used to detect file creation events
• Go loader and ring-buffer reader implementation details for moving samples into user space
• OpenTelemetry setup and Prometheus exporter code for turning events into counters and labels
• Build and test steps for running the demo in a Lima-based Linux VM
