White Paper: Mobile Network Access Control: Extending Corporate Security Policies To Mobile Devices

Network Access Control (NAC) systems protect corporate assets from threats posed by devices that lack adequate security measures. Using NAC in a mobile deployment, however, can be problematic if overly stringent enforcement impacts the worker's ability to use the device. The Mobility XE Mobile NAC module is especially designed to allow administrators to balance the response to a security concern based on severity, and the impact that remediation measures would have on worker productivity. Administrators can simply warn the user, or take more stringent action such as quarantining the device. Using Mobile NAC in conjunction with the Policy Management module allows automated remediation based on factors such as the speed of the connection or time-of-day. It also integrates with systems management software as part of a complete system for over-the-air device management.

Network Access Control (NAC) solutions protect organizations, and enforce corporate policies to keep devices configured correctly and operating at top efficiency. NAC solutions verify protection against viruses, spyware and other security threats that are transmitted via networks and networkenabled applications, or that take advantage of unpatched vulnerabilities in operating systems and applications. Network administrators use NAC solutions to monitor and manage computing devices to ensure they are compliant with corporate security requirements. Devices can be updated with operating system service packs and patches, antivirus and antispyware updates, software patches, etc., before being allowed access to corporate network resources.
