How to Build Robust and Secure Network Architectures with Segmentation
Mastering Network Segmentation: Enhancing Security and Performance
As networks expand and cyber threats evolve, network segmentation has emerged as a critical strategy for both security and performance optimization. By dividing networks into smaller, more manageable sub-networks, organizations can limit the spread of malware, improve traffic management, and enforce granular security policies.
This article explores the importance of network segmentation, its benefits, and practical implementation strategies using tools and techniques suited for modern network environments.
What Is Network Segmentation?
Network segmentation is the practice of dividing a larger network into smaller segments or subnets, each acting as an independent unit. These segments can be isolated or connected based on specific policies to control the flow of data between them.
Types of Network Segmentation
- Physical Segmentation: Achieved by using separate hardware, such as switches or routers.
- Logical Segmentation: Implemented through VLANs (Virtual Local Area Networks) or firewalls to isolate traffic virtually.
