Aruba Delivers BYOD Control with ClearPass

The bring-your-own-device (BYOD) movement is in full swing now but, while BYOD delivers some freedom to users, it’s still critical that enterprises extend the same degree of policy, access, security and control that corporate owned devices also receive to these devices.

Networking vendor Aruba is now debuting a solution for BYOD, built on Linux and leveraging the open source FreeRADIUS access control solution to help return control to enterprises.

“ClearPass provides a networking solution for BYOD to address all of the major operating systems and any networking vendor’s network architecture,” Robert Fenstermacher, director of Product Marketing at Aruba, told “It can act as a single point of policy control across all wired, wireless and remote infrastructure for a global organization.”Aruba ClearPass screen shot

There are a number of components that make up the ClearPass solution. One of them enables the automation of device onboarding including a full certificate validity responder that “enables users to bring in their own devices and in a self-service manner, get those devices onto the network,” Fenstermacher said.

The Profile component provides a detailed analysis of end points on a network. That information can be used for both visibility and reporting as well as invoking policy decision based on device or operating system. The On Guard component goes a step further turning ClearPass into a network access control (NAC) solution.

“On Guard will fully scan the devices on your network at the point of connection and it will assess the risk associated with the device,” Fenstermacher said.

Linux Inside

The ClearPass solution is not part of Aruba’s existing ArubaOS based product line that delivers wired and wireless network connectivity. ClearPass is a server appliance that runs on a CentOS Linux base and it’s also available as a virtual appliance.

Sitting at the core of the policy solution is the open source FreeRADIUS solution but the entire ClearPass product also makes use of over a year of Aruba’s own internal development.

ClearPass is intended to be complementary with Aruba’s Airwave product line, which provides wired and wireless network management capabilities.

“Airwave is for network management, while ClearPass is a policy and access management platform,” Fenstermacher explained. “We expect the two platforms to be separate, where ClearPass is where policies are created and Airwave is where you configure and troubleshoot your network.”
