Design for a three-stage skill harness (threat-model -> audit -> verify) that audits ns8-core and ns8 modules for NS8-specific security defects and validates findings against a live cluster node. Assisted-by: Claude Code:claude-fable-5
Three skills forming a defensive-security pipeline for NethServer 8: - nethserver-threat-model: map attack surface (actions, api-moduled handlers, routes/ports, Redis privilege, secret flows) -> THREAT_MODEL.md - nethserver-security-audit: static audit across auth/authz, action input, Redis privilege, api-moduled injection, secrets, proxy trust; parallel per-domain checks + grep seeder -> FINDINGS.json/.md - nethserver-security-verify: confirm findings on a live leader with read-only api-cli/runagent/podman/curl probes -> VERIFIED.md Works on both ns8-core and ns8-<app> modules. Container hardening is delegated to nethserver-containerfile. Assisted-by: Claude Code:claude-fable-5

Summary
Adds a three-stage defensive-security skill harness for NethServer 8, alongside the existing dev-workflow skills. Audits
ns8-coreor anyns8-<app>module for NS8-specific security defects, then validates findings against a live cluster node.Pipeline (
threat-model → audit → verify):nethserver-threat-model— maps the attack surface (actions, api-moduled handlers, exposed routes/ports, privileged Redis usage, secret flows, trust boundaries) →THREAT_MODEL.md.nethserver-security-audit— static audit across six NS8 domains (auth/authz, action & event input, Redis privilege boundary, api-moduled handler injection, secrets, proxy/X-Forwarded-For trust). Parallel per-domain checks + deterministicscan-antipatterns.shrecall floor →FINDINGS.json+FINDINGS.md.nethserver-security-verify— confirms each finding against a live NS8 leader with read-onlyapi-cli/runagent/podman/curlprobes →VERIFIED.md. Requests live-node access up front; degrades to static reasoning without it. No state changes unless explicitly authorized.Container-image hardening is delegated to the existing
nethserver-containerfile. Live probes reuse thenethserver8skill safety rules.Design spec included at
docs/specs/2026-07-10-ns8-security-audit-harness-design.md.Related issue

How to test
Static (no live node needed):
Confirm it surfaces (with correct file:line)
SetTrustedProxies, authzfilepath.Match,Method == "GET"bypass, emptyAMLD_JWT_SECRET, and everyredis_connect(privileged=True)site, while excluding vendored/build dirs.End-to-end: run
/nethserver-threat-model→/nethserver-security-audit→/nethserver-security-verifyagainst a test NS8 checkout and a test/staging leader node.Dependencies
None.
