Network segmentation

Increase network security and improve user experience by segmenting the network

Modern networks must support an ever-increasing number and diversity of devices. Often these are unmanaged devices, including BYOD and guest devices, that can be risker than those owned by IT. IoT devices may also be especially vulnerable to security threats. Absent any means to prevent them, security threats can readily propagate horizontally within the network environment once they have penetrated the network perimeter.

Device proliferation can also contribute to a poor user experience, particularly in certain industries such as multi-dwelling units. Users have visibility into devices that are not relevant to them, and this can create confusion. Data-intensive applications accessed by visitors may compete for bandwidth with mission-critical applications. Network segmentation—or the practice of dividing the network into multiple smaller subnetworks—can help address these challenges.

Stronger IT security with multiple virtual networks to separate devices

IT teams can improve the security posture of the network using network segmentation to isolate certain devices and groups of devices from others. This can keep threats from propagating on the network. Unmanaged and IoT devices can be placed upon their own virtual networks to mitigate the risk. That means that, if a device connects that is affected by a security threat, it won’t be able to infect other devices that are on a separate virtual network. IT can grant guest users internet access only on a separate guest network. Network segmentation can also isolate users and devices that are subject to stringent compliance requirements, making it easier to meet these requirements.

Virtualized personal networks for a better user experience 

Network segmentation can help IT teams deliver a better, more personalized experience for users. This is especially true in multi-dwelling units, including in higher education. CommScope RUCKUS® enables IT teams to segment a single physical network into multiple virtual networks—even down to the level of individual users. Since each user is on their own virtual network, they only see the devices that are relevant to them. They can roam about the network environment and still be connected to their personal virtual network. IT teams can also use network access policies to prioritize mission-critical data traffic—providing superior quality of service where it matters most to the organization.

Deployment options to support any network—whether or not it’s a RUCKUS network

CommScope offers two technologies within the RUCKUS product line to enable network segmentation—VLANs and VXLANs. VLANs can be employed whether or not the underlying network is a RUCKUS network, and this approach scales to about 4,000 separate virtual networks. RUCKUS Cloudpath® Enrollment System enables this capability. VXLANs have much higher scalability than VLANs, and enable virtual networks than span physical network segments. Deploying VXLANs on a RUCKUS network requires a SmartZone™ controller, SmartZone Data Plane and Cloudpath Enrollment System. RUCKUS products automate many tasks associated with setting up VXLANS to dramatically simplify the process.

Video: Network Segmentation 

Network segmentation is the practice of dividing the enterprise network into smaller sub-networks. It isolates users and devices from one another, to enhance IT security and the user experience. Ruckus Networks helps you simplify network segmentation on any network—and provides even stronger capabilities with a RUCKUS network.
