Patent ID: 7487358

Claim:
A storage medium having stored thereon instructions that, when executed by a machine, result in: receiving ( 705 ) a first plurality of signatures corresponding to a plurality of modules in a machine; comparing ( 715 , 720 ) the first plurality of signatures for the plurality of modules with a second plurality of signatures in a database ( 205 ); identifying ( 725 ) a first subset of the plurality of modules for which the corresponding signatures are found in the database ( 205 ) and ( 730 ) a second subset of the plurality of modules for which the corresponding signatures are not found in the database ( 205 ); and generating ( 740 ) a trust score for the machine based on the first subset of the plurality of modules for which the corresponding signatures are found in the database ( 205 ) and a second subset of the plurality of modules for which the corresponding signatures are not found in the database ( 205 ).
