What is Network Segmentation?
Network segmentation divides a network into smaller parts (zones) to limit access, increase security, and improve performance.
How does it work?
Segmentation can be implemented in different ways:
- Physical segmentation – separate physical networks
- Logical segmentation – VLANs and firewall rules
- Microsegmentation – controls access at the application level (part of Zero Trust)
Benefits of Network Segmentation:
- Limits the spread of attacks and malware
- Reduces network traffic load
- Supports compliance with regulations
- Protects industrial and sensitive systems
Challenges of Network Segmentation:
- Requires careful planning and configuration
- Misconfigurations can introduce vulnerabilities
- Remote access must be properly secured
Use Cases:
- Industrial networks
- Enterprise IT environments
- Data centers
- Healthcare and critical infrastructure
