Micro-segmentation definition
Micro-segmentation is a network security technique that divides a network into multiple isolated segments or zones. Each segment holds a specific group of resources, and policies can be applied to control traffic flow between these zones. This granular approach allows for tighter control and improved security compared to traditional perimeter-based defenses.

Micro-segmentation examples
- Data center security: Micro-segmentation is widely used in data centers to isolate workloads and protect them from lateral movements of threats.
- Cloud security: Cloud providers leverage micro-segmentation to provide individual security boundaries for customers sharing the same infrastructure.
Advantages and disadvantages of micro-segmentation
Pros:
- Enhanced security: Micro-segmentation limits unauthorized access and the lateral spread of threats within a network.
- Compliance: It helps businesses meet regulatory standards by securing sensitive data in isolated network segments.
Cons:
- Complexity: Implementing micro-segmentation requires a detailed understanding of the network and can be complex to manage.
- Cost: Initial setup and maintenance could be resource-intensive.
Using micro-segmentation
- Consider a software-based approach for more flexibility and scalability than hardware-based solutions.
- Start with high-value assets or resources, segmenting and securing them first.
