Transform cloud documentation into security baselines with OpenAI and GDrive

What this template does

Transforms provider documentation (URLs) into an auditable, enforceable multicloud security control baseline. It:

• Fetches and sanitizes HTML
• Uses AI to extract security requirements (strict 3-line TXT blocks)
• Composes enforceable controls (strict 7-line TXT blocks with true-equivalence consolidation)
• Builds the final baseline (TXT or JSON, see Outputs) with a Technology: header
• Returns a downloadable artifact via webhook and can append/create the file in Google Drive

Why it’s useful

Eliminates manual copy-paste and produces a consistent, portable baseline ready for review, audit, or enforcement tooling—ideal for rapidly generating or refreshing baselines across cloud providers and services.

Multicloud support

The workflow is multicloud by design. Provide the target cloud in the request and run the same pipeline for:

• AWS, Azure, GCP (out of the box)
• Extensible to other providers/services by adjusting prompts and routing logic

How it works (high level)

1. POST /create (Basic Auth) with { cloudProvider, technology, urls[] }
2. Input validation → generate uuid → resolve Google Drive folder (search-or-create)
3. Download & sanitize each URL
4. AI pipeline: Extractor → Composer → Baseline Builder → (optional) Baseline Auditor
5. Append/create file in Drive and return a downloadable artifact (TXT/JSON) via webhook

Request (webhook)

Method: POST URL: https://<your-n8n>/webhook/create Auth: Basic Auth Headers: Content-Type: application/json

Example input (Postman/CLI)

{
  "cloudProvider": "aws",
  "technology": "Amazon S3",
  "urls": [
    "https://docs.aws.amazon.com/AmazonS3/latest/userguide/security-best-practices.html",
    "https://www.trendmicro.com/cloudoneconformity/knowledge-base/aws/S3/",
    "https://repost.aws/knowledge-center/secure-s3-resources"
  ]
}

Field reference

• cloudProvider (string, required) — case-insensitive. Supported: aws, azure, gcp.
• technology (string, required) — e.g., "Amazon S3", "Azure Storage", "Google Cloud Storage".
• urls (string[], required) — 1–20 http(s) URLs (official/reputable docs).

Optional (Google Drive destination):

• gdriveTargetId (string) — Google Drive folderId used for append/create.
• gdrivePath (string) — Path like "DefySec/Baselines" (folders are created if missing).
• gdriveTargetName (string) — Folder name to find/create under root.

Optional (Assistant overrides):

• assistantExtractorId, assistantComposerId, assistantBaselineId, assistantAuditorId (strings)

Resolution precedence

1. Drive: gdriveTargetId → gdrivePath → gdriveTargetName → default folder.
2. Assistants: explicit IDs above → dynamic resolution by name (expects 1_DefySec_Extractor, 2_DefySec_Control_Composer, 3_DefySec Baseline Builder, 4_DefySec_Baseline_Auditor).

Validation

• Rejects empty urls or non-http(s) schemes; normalizes cloudProvider to aws|azure|gcp.
• Sanitizes fetched HTML (removes scripts/styles/headers) before AI steps.

Outputs

• Primary: downloadable TXT file controls_<technology>_<timestamp>.txt (via webhook).
• Composer outcomes: if no groups to consolidate → NO_CONTROLS_TO_BE_CONSOLIDATED; if nothing valid remains → NO_CONTROLS_FOUND.
• JSON path: when the Builder stage is configured for JSON-only output (strict schema), the workflow returns a .json artifact and the Auditor validates it (see next section).

Techniques used (from the built-in assistants)

• Provider-aware extraction with strict TXT contract (3 lines): Extractor limits itself to the declared provider/technology, outputs only Description/Reference/SecurityObjective, and applies a reflexive quality check before emitting.
• Normalization & strict header parsing: Composer normalizes whitespace/fences, requires the CloudProvider/Technology header, and ignores anything outside the exact 3-line block shape.
• True-equivalence grouping & consolidation: Composer groups only when intent, enforcement locus/mechanism, scope, and mode/setting all match—otherwise items remain distinct.
• 7-line enforceable control format: Composer renders each (consolidated or unique) control in exactly seven labeled lines to keep results auditable and automatable.
• Builder with JSON-only schema & technology inference: Builder parses 7-line blocks, infers technology, consolidates true equivalents again if needed, and returns pure JSON matching a canonical schema (with counters in meta).
• Self-evaluation loop (Auditor): Auditor unwraps transport, validates schema & content, checks provider terminology/scope/automation, and returns either GOOD_ENOUGH or a JSON instruction set for the Builder to fix and re-emit—enabling reflective improvement.
• Reference prioritization: Across stages, official provider documentation is preferred in References (AWS/Azure/GCP).

Customization & extensions

• Prompt-reflective techniques: keep (or extend) the Auditor loop to add more review passes and quality gates.
• Compliance assistants: add assistants to analyze/label controls for HIPAA, PCI DSS, SOX (and others), emitting mappings, gaps, and remediation notes.
• Implementation context: feed internal implementation docs, runbooks, or Architecture Decision Records (ADRs); use these as grounding to generate or refine controls (works with local/self-hosted LLMs, too).
• Local/self-hosted LLMs: swap OpenAI nodes for your on-prem LLM endpoint while keeping the pipeline.
• Provider-specific outputs: extend the final stage to export Policy-as-Code or IaC snippets (Rego/Sentinel, CloudFormation Guard, Bicep/ARM, Terraform validations).

Assistant configuration & prompts

• Full assistant configurations and prompts (Extractor, Composer, Baseline Builder, Baseline Auditor) are available here: https://github.com/followdrabbit/n8nlabs/tree/main/Lab03%20-%20Multicloud%20AI%20Security%20Control%20Baseline%20Builder/Assistants

Security & privacy

• No hardcoded secrets in HTTP nodes; use n8n’s Credential Manager.
• Drive operations are optional and folder-scoped.
• For sensitive environments, switch to a local LLM and provide only sanitized/approved inputs.
