eBPF Audit

Container isolation is a hypothesis, not a guarantee. A zero-install audit that probes your own infrastructure for the kernel capabilities that quietly break it.

The problem

Isolation you never tested.

Container fences — cgroups, seccomp, AppArmor, SELinux — are assumed to hold. But a process holding capabilities like CAP_SYS_ADMIN or CAP_BPF can use the shared kernel as a side door: reading a neighbour tenant’s files and secrets, reconstructing traffic, and slipping past audit logs, with no disk writes, no packets and no exploit.

These capabilities persist by default in real CI/CD runners and orchestrators. The exposure is not a novel CVE; it is a configuration nobody checked.


The approach

Test the boundary, then close it.

01

Probe for latent privilege

A self-contained audit container inspects the host and its neighbours for the dangerous capabilities and kernel exposure that enable cross-boundary observation — CAP_SYS_ADMIN, CAP_BPF, CAP_DAC_READ_SEARCH, CAP_NET_ADMIN and their kin.


02

Runs where you deploy

Zero-config, it runs on Docker, Podman, Kubernetes nodes and CI runners. You run it against infrastructure you own and operate, and it hands back a plain report of what leaks.


03

Findings map to fixes

Every finding points at a concrete mitigation: rootless containers, tighter seccomp and AppArmor profiles, disabling unprivileged eBPF, and dropping capabilities that were never needed in the first place.


Where it stands

A working audit.

eBPF Audit is a defensive tool for testing infrastructure you own and operate. Figures are internal measurements at proof-of-concept stage.


What's next

From audit to gate.

The tool grows from a one-shot audit into a CI/CD gate that fails a build when a runner exposes dangerous capabilities — so the check runs on every deploy rather than once.

eBPF Audit spins out of Research ByIQ once it runs cleanly across the major container platforms and orchestrators.
