# IBM Cloud Object Storage Security Integration | Continuous FIM, DSPM & Ransomware Defense · tamper

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

## Enterprise-Grade FIM, DSPM & DORA Compliance for IBM Cloud Object Storage.

Built for financial institutions, insurers, and industrial enterprises running IBM Cloud Object Storage (COS). tamper connects via native HMAC S3 credentials to audit vault integrity, CIS posture, and ransomware indicators.

## Why secure IBM Cloud Object Storage storage with tamper?

IBM Cloud Object Storage powers mission-critical financial and industrial repositories across Europe (`eu-de` Frankfurt, `eu-gb` London). tamper provides automated cryptographic proof of data non-alteration and continuous DSPM governance.

- **Audit-Ready Proof for Regulated Archives** (01 / FINANCIAL & DORA COMPLIANCE): Demonstrate continuous ICT data integrity and resilience required by DORA, NIS 2, and ISO 27001 across all your IBM Cloud Object Storage vaults.
- **Direct Connection to IBM COS Regional Endpoints** (02 / NATIVE HMAC S3 INTEROPERABILITY): Connect in 2 minutes using standard IBM Cloud IAM Service ID HMAC credentials (`s3.eu-de.cloud-object-storage.appdomain.cloud`) with zero agents.
- **Protect Confidential Records & PII** (03 / AI DLP & CANARY TRIPWIRES): Automatically identify exposed financial records or PII, tag sensitive objects on IBM COS, and deploy stealth canary files to trap insider threats.

## Connect IBM Cloud Object Storage in under 2 minutes

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

- **Provider**: `IBM Cloud` (Pre-configured cloud storage connector)
- **Endpoint**: `s3.eu-de.cloud-object-storage.appdomain.cloud` (e.g., s3.eu-de.cloud-object-storage.appdomain.cloud or s3-api.us-geo.objectstorage.softlayer.net)
- **Region**: `eu-de` (IBM Cloud COS region (eu-de, eu-gb, us-geo))
- **Bucket Name**: `my-ibm-bucket` (Target private IBM Cloud Object Storage bucket)
- **S3 Access Key & Secret**: `HMAC Access Key / Secret Key` (Read-Only S3 API credentials)

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

## Comprehensive Security Posture Across IBM Cloud Object Storage

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

tamper communicates with IBM Cloud Object Storage over standard HTTPS S3 endpoints (s3.eu-de.cloud-object-storage.appdomain.cloud) using AWS Signature Version 4 (SigV4).

- **1. Standard S3 SigV4 Protocol**: Full interoperability with your existing IBM Cloud Object 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.
