Abstract
A security client can efficiently authenticate an application during I/O request handling by maintaining a white list that identifies processes that have been created for authenticated applications. The security client can register to be notified when a process is being created. When such a notification is received, the security client can authenticate the application for which the process is being created and then add an entry to the white list that includes the process identifier of the process being created. Then, when the process subsequently generates I/O requests, the security client can use the white list to quickly determine that the process pertains to an authenticated application and allow the I/O requests to modify protected artifacts.
