Micro Segmentation Network

Micro segmentation is a security technique that enables fine grained security policies to be assigned to data center applications down to the workload level.

Micro segmentation network.

Network microsegmentation adds virtualization and control of software level abstraction to the subnetwork traffic controls of segmentation. Micro segmentation enables it to deploy flexible security policies deep inside a data center. Sdn virtualizes network functionality by separating the control and data planes and implementing the network intelligence in software. Micro segmentation is a network security technique that enables security architects to logically divide the data center into distinct security segments down to the individual workload level and then define security controls and deliver services for each unique segment.

Using the age old and some security professionals might say tired analogy. Unlike network segmentation micro segmentation detaches segmentation from the network by leveraging the host workload firewall to enforce policy. Micro segmentation is the most advanced way to segment networks and clouds into smaller zones enforced on individual hosts. Network segmentation is best for north south traffic and microsegmentation adds a layer of protection for east west traffic server to server application to server web to server etc.

The result is better network performance and a simpler architecture in complex virtualized and software defined data centers with fluctuating workloads. Micro segmentation is an emerging security best practice that offers a number of advantages over more established approaches like network segmentation and application segmentation. Network segmentation is the thick walls and wide moats of the castle while. While microsegmentation can be implemented with traditional networking technology sdn enabled microsegmentation is far more flexible because it enables system administrators to define and manage security.

Sometimes it is referred to as host based segmentation or security. Micro segmentation augments firewall controls to create workload perimeters for hybrid multicloud and containerized environments. The added granularity that micro segmentation offers is essential at a time when many organizations are adopting cloud services and new deployment options like. Network firewalls provide protections at the network boundary but have no visibility or control over communication that takes place within virtual data centers.

This approach enables security models. Network segmentation isn t new.
