Abstract:
1. A method comprising: determining that a reported multipurpose internet mail exchange (MIME) type for a downloaded file is inconsistent with a sniffed MIME type for the file; replacing a file extension associated with the file with an updated file extension to reconcile the reported MIME type, the file extension being replaced based on the reported MIME type being inconsistent with the sniffed MIME type; reporting a reconciled MIME type to a class ID sniffer that is configured to determine a class ID for the file based on content of the file, the updated file extension, and the reconciled MIME type; and causing the file to be executed in an executable shell determined from a security matrix that includes the class ID and the updated file extension, the security matrix being configured to map a set of user interface definitions to a security level assessment based on the updated file extension, the class ID, and one or more associated registered types.
