# Wasabi Hot Cloud Storage Security Integration | Continuous FIM, DSPM & Ransomware Defense · tamper

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

## Zero-Egress, High-Frequency S3 Integrity & Ransomware Defense for Wasabi.

Wasabi charges zero egress fees and zero API request fees. Pair Wasabi Hot Cloud Storage with tamper to run continuous hourly SHA-256 fingerprinting and Shannon entropy checks without a single cent of cloud API surcharges.

## Why secure Wasabi Hot Cloud Storage storage with tamper?

On traditional hyperscalers, frequent S3 GET/HEAD/LIST security scans can drive up API billing. Because Wasabi includes free API requests and free egress, tamper can inspect your hot backups and media archives at maximum frequency.

- **Unrestricted Hourly Cryptographic Audits** (01 / ZERO API & EGRESS FEES): Take full advantage of Wasabi's no-egress, no-API-fee model to run deep FIM and DLP entropy scans across millions of objects with zero cloud billing surprises.
- **Verify Wasabi Object Lock & Compliance** (02 / IMMUTABLE BACKUP AUDITING): Continuously audit bucket-level Object Lock, Versioning, and access policies across Wasabi regions (Paris eu-west-2, Amsterdam eu-central-1, Frankfurt).
- **Detect Compromised Backup Credentials** (03 / RANSOMWARE EARLY WARNING): Spot unauthorized deletions, silent file corruption, or encrypted uploads on your Wasabi buckets within minutes and alert Slack, Jira, PagerDuty, or Wazuh.

## Connect Wasabi Hot Cloud Storage in under 2 minutes

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

- **Provider**: `Wasabi` (Pre-configured cloud storage connector)
- **Endpoint**: `s3.eu-west-2.wasabisys.com` (e.g., s3.eu-west-2.wasabisys.com (Paris) or s3.eu-central-1.wasabisys.com)
- **Region**: `eu-west-2` (Wasabi storage region (eu-west-2 Paris, eu-central-1 Amsterdam, us-east-1))
- **Bucket Name**: `my-wasabi-bucket` (Target private Wasabi Hot Cloud Storage bucket)
- **S3 Access Key & Secret**: `WAS... / ...` (Read-Only S3 API credentials)

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

## Comprehensive Security Posture Across Wasabi Hot Cloud Storage

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

tamper communicates with Wasabi Hot Cloud Storage over standard HTTPS S3 endpoints (s3.eu-west-2.wasabisys.com) using AWS Signature Version 4 (SigV4).

- **1. Standard S3 SigV4 Protocol**: Full interoperability with your existing Wasabi Hot Cloud 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.
