The fingerprint value of the firmware or software of a client device is received and the validity of the fingerprint is verified. Network access control device is notified when the fingerprint of the firmware or software from the client device is determined to be not authorized.
Claims23
A method for validating firmware or software at a client device that can access a network controlled by a network access control device, comprising:
- receiving from the client device a value of a fingerprint of the firmware or software;
- verifying validity of the fingerprint of the firmware or software received from the client device;
- and
- notifying the network access control device when the fingerprint of the firmware or software from the client device is not authorized.
A method for validating firmware or software at a client device that can access a network controlled by a network access control device, comprising:
- the client device receiving from a server a request for a fingerprint value of the firmware or software;
- and
- the client device providing a value of a fingerprint of the firmware or software using a hash algorithm.
A system for validating firmware or software at a client device that can access a network, comprising:
- a validation server, said server including a fingerprint database for verifying whether a fingerprint of the firmware or software at the client device is authorized;
- and
- a network access control device, said validation server sending a message to the network access control device when the fingerprint of the client device is not authorized, said network access control device controlling access to the network by the client device in response to the message from the validation server.
