The rise of the data center means that we are storing more financial, medical and sensitive corporate data off-premises. Yet many data centers are still basing security on the old model of securing the perimeter — a method that is no longer effective on its own in today’s evolving threat landscape.
Attacks are increasing in their frequency and sophistication, and new approaches are needed to protect sensitive assets. A new approach that’s growing in popularity is micro-segmentation. This growing security trend enables fine-grained security policies to be applied to data center applications and individual workloads through virtualization. This software-only approach allows you to protect your data and applications if the hardware-based firewall is breached.
How Micro-segmentation Security Works
Micro-segmentation protects sensitive data by restricting an attacker's ability to move laterally within your data center infrastructure.
Micro-segmentation uses a virtualized, software-only model to assign security policies to individual workloads, allowing those policies to synchronize with the virtual network, virtual machines and operating systems. Policies can move with the virtual machine or workload in the case of migration or network reconfiguration.
The idea of ‘zero trust’ coined by Forrester Research is central to the concept of micro-segmentation and means that only the necessary actions and connections are enabled in a workload or application, and all else is blocked. Until now, micro-segmentation has been possible, but it’s been resource and cost-prohibitive, but network virtualization has enabled micro‐segmentation to become a reality in the software‐defined data center.
The Benefits of Micro-segmentation
Micro-segmentation holds key advantages for IT security and business operations, including:
Micro-segmentation and network virtualization are boosting security by providing persistent security that moves with an application or workload even if the network is reconfigured. Organizations who have adopted micro-segmentation are experiencing enhanced innovation to improve the customer experience and achieve a competitive advantage by creating secure virtual networks.
