Secure Data Flow Architecture: End-to-End Encryption & Access Control #3379832 (License: Personal Use)

This diagram depicts a comprehensive enterprise security model where end users (via workstations or handheld devices) authenticate and gain controlled access to systems. Traffic passes through external and internal firewalls, then flows through web and application servers before reaching the database, which enforces encryption for data at rest and in motion. Each layer includes explicit access controls to minimize attack surface and ensure least-privilege principles.

Used on cybersecurity training pages, cloud architecture documentation, or IT compliance guides; supports user intent to understand defense-in-depth strategies, zero-trust models, or GDPR/HIPAA-compliant system design.
