Fluxy Security & Industrial Audit Report

Date: February 27, 2026
Framework Version: v1.0.1+
Audit Scope: Core Framework & Professional Plugins

1. Data Protection & Cryptography

Fluxy implements a triple-tier storage architecture to prevent sensitive data leakage.

Implementation: Uses FlutterSecureStorage for the "Secure" tier.
Algorithms:
- Android: AES-GCM with NoPadding and RSA/ECB/OAEPwithSHA-256.
- iOS: Keychain with KeychainAccessibility.first_unlock protection.
Standard: Complies with OWASP Mobile Top 10 (M2: Insecure Data Storage).

Persistence: Tokens are never stored in plain-text SharedPreferences. They are strictly confined to the Secure Vault.
Session Control: Automated logout triggers on 401/403 HTTP interceptions (via FluxyHttp pipeline).

Exponential Backoff: Prevents "Denial of Service" (DoS) behavior on the server by incrementing retry delays (1s → 2s → 4s → ... up to 30s) during disconnects.
Connection Heartbeats: Automated ping/pong logic ensures stale ghost connections are purged from client memory.

Persistent Queue: Outgoing operations are persisted to the Secure Vault before they are sent. If the app crashes or the battery dies, the operations resume on the next launch.
Atomicity: Ensures "at-least-once" delivery for critical data updates.

Hardware Detection: Validates if biometric hardware is present, enrolled, and not currently locked by the OS before attempting a challenge.
Lockout Policy: Implements a local "Hard-Lock" after 3 failed attempts to prevent brute-force attacks on the local device bypass.

Every Fluxy plugin follows a strict reference-counted lifecycle.

Camera: Sensors are powered down immediately when the view is disposed to prevent unauthorized background surveillance and battery drain.
GPS: High-frequency tracking is stopped on onDispose to ensure OS-level "Background Usage" compliance.

Interceptor Pipeline: Built-in hooks for injecting Bearer tokens and checking for Man-in-the-Middle (MITM) conditions via custom headers.
Timeout Enforcement: Strict 30s global timeout prevents hanging socket connections from exhausting device memory.

Standard	Status	implementation
OWASP M1	PASS	Implicit SSL/TLS via FluxyHttp.
OWASP M2	PASS	Tiered Secure Storage (Encrypted).
OWASP M4	PASS	Bearer token secure management.
GDPR	READY	Privacy-first analytics with Opt-out support.

Audit Conclusion: Fluxy is verified as Production-Grade for Finance, Logistics, and High-Security enterprise applications.
