Secure Network Design

bCom Whitepaper | Principles and patterns for building resilient, secure infrastructure

Introduction

Well-designed networks are the foundation of secure IT operations. This whitepaper covers key principles and patterns for building resilient, secure infrastructure.

Core Principles

Defense in depth: Multiple layers of security. Least privilege: Grant only necessary access. Segmentation: Isolate critical assets. Monitoring: Visibility into network traffic and events.

Design Patterns

DMZ for public-facing services; VLANs for internal segmentation; zero-trust approaches for modern environments; secure wireless design with proper authentication.

Implementation Considerations

Balance security with usability. Plan for scalability and change. Document architecture and maintain it. Regular reviews and updates are essential.
