🚀 How to Upload AWS Findings to Sentinel (Security Hub)

Project: e.g. AWS Compliance Products (Pilot Test):

• ProductA

• ProductB

---

🔄 Automation Flow

Step 1: Maintain Account-to-Product Mapping

• Create and store a mapping of AWS accounts to products.

  • Example:

    • Account A → ProductA

    • Account B → ProductB

• Store this mapping in a central source of truth (e.g., SnipeIT, Confluence, CMDB).

• Purpose: ensures each AWS account’s findings are categorized to the right product.

---

Step 2: Collect Findings into a Central S3 Bucket

• Use a special AWS Management Account to pull findings from all AWS accounts.

• Findings are gathered via AWS Lambda (scheduled run).

• Store results in an S3 bucket, organized by product (Datalake / ITS).

---

Step 3: Merge & Format Findings for Sentinel

• Consolidate findings into one CSV per product.

• The CSV must follow Sentinel’s required schema (default AWS plugin):

Id,ProductName,Remediation,Remediation_URL,Compliance,WorkflowStatus,RecordState,ProcessedAt,Title,severity,Status,Region,Account_id,Description,Resource_id,Resource_tags

⚠️ Important:

• Headers must match exactly — if not, Sentinel will reject the upload.

---

Step 4: Push Findings to Sentinel (via API)

Requirements:

• API Base URL

• API Key (for authentication)

• Plugin Name

• Correct Product ID (e.g., 1fbfe77b-ed4b-4028-b6aa-029ed4f35116)

Process:

1. Use Python, Lambda, or another automation script to:

   • Authenticate with Sentinel API using the API key.

   • Call the upload endpoint with the Product ID and Plugin Name.

   • Upload the CSV file (merged findings).

2. Validate the API response to confirm successful ingestion.

⚠️ Caution:

• Using the wrong Product ID will place findings under the wrong product in Sentinel.

---

Step 5: Access Reports in Sentinel

• Log in to Sentinel Portal → Product View.

• Uploaded findings are:

  • Searchable

  • Filterable

  • Trackable for remediation

✅ Final Flow Recap

1. Store account mapping → SnipeIT / Confluence

2. Extract findings → Lambda → S3 (grouped by product)

3. Merge findings → Sentinel CSV format

4. Push findings → Sentinel API (Product ID + API key)

5. Access findings → Sentinel Portal
