Abstract
An apparatus comprises at least one processing device comprising a processor coupled to a memory, with the at least one processing device being configured to provide at least a portion of an input-output (IO) stack for processing of IO operations in a host device for delivery to a storage system over selected ones of a plurality of paths through a network. The IO stack comprises at least a multi-path device overlying one or more logical storage devices. The at least one processing device is further configured to perform a check at each of one or more points in the IO stack to confirm that a given IO operation directed to a given device of the IO stack is received from an expected overlying device of the IO stack. The IO stack illustratively comprises an encryption device overlying the multi-path device, supporting end-to-end encryption for one or more logical storage devices.
