Hi can someone tell me what will be the behavior of Cisco NAC in the following scenario?

In a corporate LAN a user (all ready authenticated on domain) decides (because he can) to install a USB dongle that will give him access to Internet by mobile phone carrier (GPRS, 3G). What will be the behavior for NAC, it will block the connection for USB dongle? Will block the connection to corporate network?

Thanks a lot

In this situation the NAC Appliance provides security threat protection for WLANs by enforcing device security policy compliance when WLAN clients attempt to access the network. These solutions quarantine non-compliant WLAN clients and provide remediation services to help ensure compliance.

NAC will check the user only when he tries to access the network. Once he is trusted, he is not checked anymore. Therefore, if the user is already authenticated, the user can do anything he wants on his PC and NAC will have no idea of what is happening. To stop such things to happen you need CSA.
