Abstract
Systems and methods for selective authorization of code modules are provided. According to one embodiment, a trusted service provider maintain a cloud-based whitelist containing cryptographic hash values including those of code modules that are approved for execution on computer systems of subscribers of the service provider. A code module information query, including a cryptographic hash value of a code module, is received from a computer system of a subscriber by the service provider. If the cryptographic hash value matches one the cryptographic hash values contained within the cloud-based whitelist and the code module is an approved code module, then the service provider responds with an indication that the code module is authorized for execution; otherwise, it (i) responds with an indication that the code module is an unknown code module; and (ii) causes one or more behavior analysis techniques to be performed on the code module.
