# Leviia Security Integration | Continuous FIM, DSPM & Ransomware Defense · tamper

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

## 100% French Sovereign S3 Security & Backup Resilience for Leviia.

Combine Leviia's ultra-fast French sovereign S3 object storage with tamper's French cryptographic FIM & DSPM engine. Achieve extraterritorial immunity, NIS 2 compliance, and verified anti-ransomware backup integrity.

## Why secure Leviia storage with tamper?

Leviia and tamper share the same DNA: 100% French sovereign technology built to protect SMBs, mid-caps (ETIs), and public institutions from ransomware without US Cloud Act exposure.

- **Zero Extraterritorial Exposure** (01 / 100% FRENCH SOVEREIGNTY): Both your Leviia S3 buckets in France and your tamper security instance operate strictly under French and European jurisdiction (GDPR & NIS 2).
- **Cryptographic Verification of Object Lock** (02 / 3-2-1-1-0 BACKUP ASSURANCE): tamper continuously audits Leviia bucket immutability (Object Lock WORM & Versioning) and verifies SHA-256 hashes across your backup archives.
- **High-Frequency Audits Without Egress Penalties** (03 / PREDICTABLE FINOPS): Leverage Leviia's transparent pricing to run hourly integrity and entropy checks with tamper at a predictable monthly cost.

## Connect Leviia in under 2 minutes

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

- **Provider**: `Leviia` (Pre-configured cloud storage connector)
- **Endpoint**: `s3.eu-west.leviia.com` (e.g., s3.eu-west.leviia.com)
- **Region**: `eu-west` (Leviia sovereign French region)
- **Bucket Name**: `my-leviia-bucket` (Target private Leviia bucket)
- **S3 Access Key & Secret**: `LEV... / ...` (Read-Only S3 API credentials)

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

## Comprehensive Security Posture Across Leviia

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

tamper communicates with Leviia over standard HTTPS S3 endpoints (s3.eu-west.leviia.com) using AWS Signature Version 4 (SigV4).

- **1. Standard S3 SigV4 Protocol**: Full interoperability with your existing Leviia 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.
