Abstract

Signatures are generated for modules in a computer system. The signatures can be assembled into an integrity log. The signatures are compared with signatures in a database in an integrity validator. Once signatures are either validated or invalidated, a trust score can be generated. The trust score can then be used to determine whether the computer system should be granted access to a resource using a policy.

Independent Claims | See all claims (11)

  1. 1. 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).
