# Alibaba Cloud OSS Security Integration | Continuous FIM, DSPM & Ransomware Defense · tamper

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

## Cross-Border S3 Security, FIM & GDPR Governance for Alibaba Cloud OSS.

Maintain unified European security standards across your Alibaba Cloud Object Storage Service (`oss-eu-central-1` Frankfurt and global regions). tamper delivers agentless FIM, DSPM posture scoring, and AI DLP.

## Why secure Alibaba Cloud OSS storage with tamper?

International retail, manufacturing, and logistics groups operating across Europe and Asia rely on Alibaba Cloud OSS. tamper lets your European SOC enforce uniform FIM, DSPM, and DLP policies on OSS via standard S3 APIs.

- **Enforce GDPR & NIS 2 Controls on OSS Buckets** (01 / CROSS-BORDER GOVERNANCE): Audit Alibaba Cloud OSS buckets in Frankfurt (`oss-eu-central-1`) and worldwide from your sovereign tamper instance without exporting sensitive data.
- **Track Integrity of Contracts, Schematics & Catalogs** (02 / SUPPLY-CHAIN & RETAIL PROTECTION): Detect unauthorized edits, silent corruption, or exfiltration attempts on sensitive industrial schematics and commercial records stored in OSS.
- **Same Alerts & Policies as AWS, Azure & OVHcloud** (03 / UNIFIED MULTI-CLOUD SOC): Eliminate security blind spots in international subsidiaries by connecting Alibaba Cloud OSS to your central tamperOne dashboard and SIEM.

## Connect Alibaba Cloud OSS in under 2 minutes

tamper connects natively via standard Alibaba Cloud OSS read-only S3 API credentials with zero disruption to your existing workflows.

- **Provider**: `Alibaba Cloud` (Pre-configured cloud storage connector)
- **Endpoint**: `oss-eu-central-1.aliyuncs.com` (e.g., oss-eu-central-1.aliyuncs.com)
- **Region**: `oss-eu-central-1` (Alibaba Cloud Object Storage Service region (oss-eu-central-1 Frankfurt))
- **Bucket Name**: `my-alibaba-bucket` (Target private Alibaba Cloud OSS bucket)
- **S3 Access Key & Secret**: `LTAI... / ...` (Read-Only S3 API credentials)

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

## Comprehensive Security Posture Across Alibaba Cloud OSS

- **FIM (File Integrity Monitoring) - Cryptographic Object Fingerprinting**: Tracks SHA-256 baselines across all Alibaba Cloud OSS objects, identifying unauthorized modifications and silent corruption.
- **DSPM (Data Security Posture Management) - Bucket Configuration & Access Controls**: Continuously audits Alibaba Cloud OSS 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 Alibaba Cloud OSS

tamper communicates with Alibaba Cloud OSS over standard HTTPS S3 endpoints (oss-eu-central-1.aliyuncs.com) using AWS Signature Version 4 (SigV4).

- **1. Standard S3 SigV4 Protocol**: Full interoperability with your existing Alibaba Cloud OSS 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.
