Abstract
A system verifies configuration of a device within a network via an exchange of verification credentials, which are requested, received and authenticated. The verification credentials indicate that a configuration of the device was acceptable at the time of creation of the verification credentials for that device. The verification credentials of the device are obtained through a certifying process. During the certifying process, the credential certifier receives a current device configuration of the device in the network, and evaluates the current device configuration of a device with respect to its role within a network. The verification credentials are issued to the requesting device and stored within a database. The device submits its verification credentials if being requested by the other peer it's communicating with when it enters the network. It also monitors the current device configuration and if there are changes, it invalidates the existing certification credentials and requests new one.
