What We Test
The Security Test Harness covers 21 modules across six areas:
Firewall and network: nginx configuration validity, open port exposure, and live security header verification across all four SpeyBooks domains.
Secrets and configuration: SSH hardening (root login, password auth, X11), PostgreSQL binding, environment file permissions, and TLS version enforcement.
Patch management: operating system update status, Node.js LTS verification, PostgreSQL version, and production npm vulnerability scanning.
Access control: Row-Level Security coverage across all 40 tenant tables (organisation_id presence, RLS enabled, FORCE enforced), fail2ban jail status, nginx rate limiting, and auth audit log activity.
Malware and services: SUID/SGID binary baseline comparison and unexpected service detection.
Operations: SSL certificate expiry across all domains, local backup recency, disk usage, and S3 sync verification.
Infrastructure
SpeyBooks runs on Hetzner (Germany, EU) with encrypted database backups replicated to AWS London (eu-west-2, UK). Data never leaves UK or EU jurisdiction.

Operational details that would aid reconnaissance are mechanically redacted at the publication boundary; the full-fidelity report stays with the operator.
