Abstract
A system includes a processor. The processor is configured to receive network traffic that includes a data block. The processor will generate a unique identifier (UID) for the file that includes a hash value corresponding to the file. The processor will determine whether the file is indicated as good or bad with the previously-stored UID. The processor will call a file-type specific detection nugget corresponding to the file's file-type to perform a full file inspection to detect whether the file is good or bad and store a result of the inspection together with the UID of the file, when the file is determined to be not listed in the previously-stored UIDs. The processor will not call the file-type specific detection nugget when the file's indicator is 'good' or 'bad' in the previously-stored UIDs. The processor will issue an alert about the bad file when the file's indicator is “bad”.
