n8n Security Bible: Attacks, Defenses, and Hardening for Self-Hosted, Open-Source Automation (Paperback) (ISBN-13: 9798298748452)

Are your n8n workflows safe when a dependency shifts at 2 a.m.? Will your logs surface exfiltration before customers notice? This field guide turns fragile automation into hardened, observable, and auditable systems you can trust in production.

Automation Security with n8n shows engineers and operators how to design, build, and run n8n with security controls at every stage: source, build, deploy, and run. It uses real tools and concrete configs you can copy, adapt, and ship. Coverage spans containers, embedded Linux bases, and AI connectors that rely on tokens and changing versions.

What sets this book apart? It delivers end-to-end patterns that enforce safety by default and prove it with repeatable tests, signatures, and logs that stand up in reviews.

Inside, you'll discover:

SBOMs with Syft, signed images with Cosign, verified at deploy

GitHub Actions that pin versions, run tests, and gate promotions

Policy as code with OPA and Conftest for nodes and images

Structured logging with field redaction, shipped reliably to ELK or Loki

Prometheus alerts and Grafana rules for n8n health and anomalies

Kill switches, isolation steps, and token rotation with Vault and scripts

Why use this book:

Replace ad-hoc fixes with policy-driven, testable controls across the stack

Shorten incident timelines with proven playbooks and actionable queries

Pass security reviews with traceable signatures, approvals, and audit trails

Meet compliance needs while keeping developer speed and CI feedback fast

Apply patterns that work with AI connectors, rate limits, and version churn

Highlights / mini-TOC:

Appendices: Checklists, Labs, and Reference Configs

Across the book, you will pin versions, verify sources, and stop surprise changes from entering production. You will scan and sign artifacts, mandate pull-request checks, and promote only builds that meet policy. You will add structured logs with redaction at the source, ship them with agents, and query suspicious patterns in a SIEM. You will set alerts in Prometheus and Grafana, practice kill-switch containment, and rotate compromised keys quickly. You will route data by classification, apply field-level controls for PII, and produce audit trails that match regulatory expectations. You will establish encrypted backups, test restores, and track recovery targets. For teams building connectors on embedded Linux or calling AI services, you will scope tokens, constrain egress, and validate output to prevent quiet failure.
