# Azure Blob Storage Security Integration | Continuous FIM, DSPM & Ransomware Defense · tamper

> Secure your Azure Blob Storage buckets with continuous File Integrity Monitoring (FIM), DSPM posture auditing, and early ransomware detection via native S3 API.

## Unify Multi-Cloud Governance & Backup Integrity on Azure Blob Storage.

Bring Azure Blob Storage and your S3 clouds under a single cryptographic security console. tamper audits your Azure containers for silent backup corruption, configuration drift, and early-stage ransomware encryption.

## Why secure Azure Blob Storage storage with tamper?

Enterprise teams running Microsoft 365, Entra ID, and Azure workloads often struggle with fragmented security tools between Azure Blob Storage and S3 clouds. tamper unifies FIM, DSPM, and AI DLP across your hybrid storage estate.

- **Single Pane of Glass Across Azure & S3** (01 / MULTI-CLOUD UNIFICATION): Apply the exact same cryptographic FIM baselines, CIS posture scoring, and alerting rules across Azure Blob Storage, AWS S3, and European sovereign clouds.
- **Protect Veeam & Commvault Repositories** (02 / BACKUP VERIFICATION): Ensure off-site enterprise backups stored in Azure francecentral or westeurope remain 100% uncorrupted and restorable when a disaster strikes.
- **Catch Compromised Service Principals** (03 / LATERAL THREAT DEFENSE): If an attacker compromises an Azure storage key and begins encrypting blobs, tamper flags the Shannon entropy jump within the very first hour.

## Connect Azure Blob Storage in under 2 minutes

tamper connects natively via standard Azure Blob Storage read-only S3 API credentials with zero disruption to your existing workflows.

- **Provider**: `Azure` (Pre-configured cloud storage connector)
- **Endpoint**: `blob.core.windows.net` (e.g., <account>.blob.core.windows.net or S3-compatible proxy endpoint)
- **Region**: `francecentral` (Azure region (e.g., francecentral, westeurope, eastus))
- **Bucket Name**: `my-azure-bucket` (Target private Azure Blob Storage bucket)
- **S3 Access Key & Secret**: `AccountName / AccountKey` (Read-Only S3 API credentials)

> Principle of Least Privilege: tamper strictly operates in Read-Only mode on Azure Blob Storage. tamper never requests write or delete privileges on your production objects.

## Comprehensive Security Posture Across Azure Blob Storage

- **FIM (File Integrity Monitoring) - Cryptographic Object Fingerprinting**: Tracks SHA-256 baselines across all Azure Blob Storage objects, identifying unauthorized modifications and silent corruption.
- **DSPM (Data Security Posture Management) - Bucket Configuration & Access Controls**: Continuously audits Azure Blob Storage bucket visibility, encryption settings, Object Lock, Versioning, and lifecycle rules against CIS security benchmarks.
- **DAM (Data Access Monitoring) - Access Anomaly & S3 Gateway Protection**: Monitors data access patterns and supports optional inline protection via the tamper S3 Gateway for real-time request filtering and anti-wiper quotas.
- **DLP (Data Loss Prevention & Ransomware Guard) - Entropy Qualification, AI Tagging & Canaries**: Detects encryption spikes (~7.99 Shannon entropy), qualifies document alterations with local AI, and monitors stealth canary objects.

## Technical Architecture: Native S3 API Compatibility with Azure Blob Storage

tamper communicates with Azure Blob Storage over standard HTTPS S3 endpoints (blob.core.windows.net) using AWS Signature Version 4 (SigV4).

- **1. Standard S3 SigV4 Protocol**: Full interoperability with your existing Azure Blob Storage pipelines, backup tools (Veeam, rclone, restic), and cloud-native applications.
- **2. 100% Agentless Operation**: Audits run externally on your dedicated VM or tamper appliance without deploying any software inside your compute instances.
- **3. Strict Read-Only Boundary**: Non-destructive cryptographic inspection ensures your object payloads, custom metadata, and version histories are never altered.
