SharePoint Download Monitoring with Azure Storage & Interactive Dashboard

What We Built

Ever wonder who's downloading what from your SharePoint sites? Are you tired of playing detective when sensitive files mysteriously "walk away" from your organization? This guide will transform you from a SharePoint storage landlord into a full-fledged digital surveillance expert with a modern twist.

Solution Overview

This modernized solution leverages Azure Storage Static Website hosting to create an interactive web dashboard that visualizes SharePoint download patterns, user behavior, and security insights. We're moving beyond static Excel reports hidden in SharePoint folders to a sleek, real-time dashboard that updates automatically.

Modern Architecture

Perfect for compliance officers who need pretty charts, security teams who love interactive data, and anyone who's ever had to explain download patterns during a Monday morning panic meeting with actual visual evidence instead of spreadsheet rows.

Choose Your Implementation Path

This guide provides two distinct implementation options for SharePoint download monitoring. Choose the approach that best fits your security requirements and technical preferences:

Azure Storage Static Website

Recommended • Modern Architecture

Features:

Interactive web dashboard with Chart.js
Mobile-responsive design
Global CDN delivery
Real-time JSON data feeds
Lower cost than SharePoint storage

Requirements:

• Azure Storage Account
• Read-only SharePoint permissions
• Azure Automation setup

Best for: Organizations wanting modern dashboards, mobile access, and enterprise-grade hosting.

SharePoint Direct Upload

"Simpler" Setup • Traditional Approach

Features:

💡 Why "Simpler" is in Quotes

While Option 2 seems simpler at first glance, it requires configuring Sites.Selected permissions for each SharePoint site you want to monitor, plus managing file uploads and versioning. Option 1 provides a more scalable, modern solution with better long-term maintenance.

Shared Technology Stack

Both implementation options share the same core monitoring infrastructure. The difference is primarily in how and where the reports are stored and accessed.

Core Technologies

PowerShell 7.2+
Microsoft Graph API
Exchange Online PowerShell
Certificate-based authentication

Infrastructure Options

Option 1: Azure Storage + Chart.js
Option 2: SharePoint + Excel files
Azure Automation (both options)
Same monitoring capabilities

What's New in This Version

Prerequisites

Before we dive into this digital surveillance setup with a modern twist, let's make sure you have everything you need. Think of these as the ingredients for your SharePoint monitoring recipe with a dash of Azure Storage magic.

1 Azure subscription with Storage Account access

2 SharePoint Online admin access for site monitoring

3 PowerShell 7.2+ for automation scripts

4 Microsoft 365 Global Admin or Security Admin rights

5 Basic knowledge of Azure portal navigation

Common Setup Requirements

These steps are required for both implementation options. Complete these first, then proceed to your chosen implementation path.

Step 1: Get Site and Drive ID

First, we need to identify your SharePoint site using Microsoft Graph API:

1 Navigate to Microsoft Graph Explorer

2 Sign in with a user account that has owner permissions on the target SharePoint site

3 Execute the Graph API query to get your site ID

Microsoft Graph API - Site Query

https://graph.microsoft.com/v1.0/sites/{hostname}:/{server-relative-path-to-site}

Example:
https://graph.microsoft.com/v1.0/sites/mscloudninja.sharepoint.com:/sites/files_to_query

4 From the response, copy the site ID and use it to get the drives information:

Microsoft Graph API - Drive Query

https://graph.microsoft.com/v1.0/sites/{site-id}/drives

💡 Technical Insight: The site ID and drive ID are required for both implementation options to identify which SharePoint sites and document libraries to monitor.

Step 2: Create Self-Signed Certificate

Generate a secure certificate for authentication (required for both options):

1 Open PowerShell as Administrator and run the certificate creation command

2 Launch Certificate Manager by running certlm

3 Export certificate twice: with and without private key

PowerShell - Certificate Generation

New-SelfSignedCertificate `
-Subject 'CN=SharePointLogs' `
-KeyLength 2048 `
-KeyUsageProperty All `
-KeyAlgorithm 'RSA' `
-HashAlgorithm 'SHA256' `
-Provider 'Microsoft Enhanced RSA and AES Cryptographic Provider' `
-NotAfter (Get-Date).AddYears(10) `
-KeyExportPolicy Exportable

💡 Technical Insight: Self-signed certificates provide secure authentication for service-to-service communication and are required for both Azure Storage and SharePoint upload options.

Step 3: Create Base App Registration

1 Navigate to Entra ID > App Registrations and create a new registration

2 Upload the certificate in Certificates & secrets

3 Configure base API permissions (additional permissions vary by option)

Base Required Permissions (Both Options)

AuditLog.Read.All - Read audit log data
Group.Read.All - Read group information
User.Read.All - Read user profiles
Exchange.ManageAsApp - Exchange Online access

⚠️ Important: Additional SharePoint permissions will be configured in the implementation-specific sections below based on your chosen option.

Option 1: Azure Storage Static Website Implementation

Modern Dashboard Solution

This option creates an interactive web dashboard hosted on Azure Storage with real-time charts, mobile responsiveness, and global CDN delivery. Follow these additional steps after completing the common setup above.

1A. Create Azure Storage Account with Static Website

1 Navigate to the Azure Portal - Create Storage Account

2 Choose StorageV2 (general purpose v2) for account kind

3 Enable Static website in the storage account settings

4 Create containers: $web (for dashboard files) and data (for JSON data)

1B. Configure App Registration for Read-Only Access

Add these permissions to your existing app registration for the Azure Storage option:

Additional Permissions for Option 1

Sites.Read.All - Read SharePoint data (read-only)

🔐 Security Advantage: This option only requires read access to SharePoint since reports are stored in Azure Storage, significantly reducing the security footprint.

1C. Configure Storage Account Access

CORS Configuration

Allowed origins: * (or your domain)
Allowed methods: GET, POST
Allowed headers: *
Max age: 3600

Access Keys

Copy storage account name and access key for script configuration.

Option 2: SharePoint Direct Upload Implementation

Traditional SharePoint Solution

This option uploads Excel/CSV reports directly to SharePoint document libraries. While it seems simpler, it requires additional permission configuration for each site you want to monitor.

2A. Configure Sites.Selected Permissions

For the SharePoint upload option, replace Sites.Read.All with Sites.Selected for enhanced security:

1 Add Sites.Selected permission to your app registration

2 Use PowerShell to grant specific site permissions for each SharePoint site:

PowerShell - Sites.Selected Configuration

# Connect to Microsoft Graph
Connect-MgGraph -Scopes "Sites.FullControl.All"

# Configure for each SharePoint site you want to monitor
$appId = "your-app-id-here"
$siteUrl = "https://yourtenant.sharepoint.com/sites/yoursite"

# Grant the app read/write access to the specific site
$site = Get-MgSite -SiteId "$($siteUrl):"
Grant-MgSitePermission -SiteId $site.Id -Roles "write" -GrantedToIdentities @{
    Application = @{
        Id = $appId
        DisplayName = "SharePoint Download Monitor"
    }
}

# Repeat for each site you want to monitor
# Verify the permission was granted
Get-MgSitePermission -SiteId $site.Id

⚠️ Important: You must repeat the permission grant process for every SharePoint site you want to monitor. This is why it's called "simpler" in quotes - it requires more ongoing permission management.

2B. Prepare SharePoint Document Libraries

1 Create a dedicated document library for download reports (e.g., "Download Reports")

2 Configure appropriate permissions for users who need access to the reports

3 Plan your file naming convention (e.g., "SharePoint_Downloads_YYYY-MM-DD.xlsx")

2C. Script Modifications for SharePoint Upload

The PowerShell script will need these modifications for SharePoint upload instead of Azure Storage:

PowerShell - SharePoint Upload Modification

# Replace Azure Storage upload section with SharePoint upload
# Export to Excel/CSV instead of JSON
$downloadData | Export-Excel -Path "$env:TEMP\SharePoint_Downloads_$(Get-Date -Format 'yyyy-MM-dd').xlsx" -AutoSize

# Upload to SharePoint using Graph API
$uploadUrl = "https://graph.microsoft.com/v1.0/sites/$siteId/drive/root:/Download Reports/SharePoint_Downloads_$(Get-Date -Format 'yyyy-MM-dd').xlsx:/content"
$fileBytes = [System.IO.File]::ReadAllBytes("$env:TEMP\SharePoint_Downloads_$(Get-Date -Format 'yyyy-MM-dd').xlsx")

$headers = @{
    'Authorization' = "Bearer $accessToken"
    'Content-Type' = 'application/octet-stream'
}

Invoke-RestMethod -Uri $uploadUrl -Method PUT -Body $fileBytes -Headers $headers

PowerShell Script Configuration (Both Options)

The core PowerShell script is the same for both implementation options. The difference is in the output format and storage destination. Here's how to configure the shared components:

Common Script Variables

Update these variables in the PowerShell script regardless of your chosen implementation:

$tenantId

Your Azure AD tenant ID

$clientId

App registration client ID

$certificateThumbprint

Script Architecture and Technical Deep Dive

Authentication Flow

The automation script uses certificate-based authentication to establish secure connections with Microsoft Graph and Exchange Online. Here's what happens under the hood:

1 Certificate Retrieval: The script retrieves the certificate from Azure Automation's secure certificate store

2 Token Request: Uses the certificate to request an OAuth 2.0 access token from Azure AD

3 API Authentication: The token is used to authenticate API calls to Microsoft Graph and Exchange Online

4 Audit Log Access: Queries the Office 365 Unified Audit Log for SharePoint download events

Data Processing Pipeline

The script implements a sophisticated data processing pipeline:

Event Filtering: Filters audit log events to focus on SharePoint file download activities
Data Enrichment: Enhances raw audit data with user and site information
JSON Generation: Creates structured JSON data for dashboard consumption
Azure Storage Upload: Uploads the generated data to Azure Storage for dashboard access

Error Handling and Resilience

Production-ready automation requires robust error handling:

PowerShell - Error Handling Pattern

# Example error handling pattern
try {
    $auditData = Search-UnifiedAuditLog -StartDate $startDate -EndDate $endDate -Operations FileDownloaded
    Write-Output "Retrieved $($auditData.Count) audit records"
}
catch {
    Write-Error "Failed to retrieve audit data: $($_.Exception.Message)"
    # Implement fallback logic or notification here
}

Advanced Configuration Options
