The emergence of virtualized data centers, public cloud infrastructure, and more dynamic DevOps approaches makes the need for granular network- and application-level security controls more important than ever. Micro-segmentation is the most effective method of protecting sensitive data within these rapidly changing hybrid cloud environments.
Micro-segmentation enables visibility, alerting, and policy enforcement from the network level all the way down to the individual process level. However, the power and flexibility of micro-segmentation can also make it challenging to identify the optimal micro-segmentation methods for a specific organization. Both over-segmentation and under-segmentation can present challenges as IT security teams try to strike a balance between improving security and avoiding disruption of business processes. However, when an optimal mix of micro-segmentation methods is implemented, it provides proactive security and compliance controls and accelerates breach detection.
