Abstract
An apparatus comprises a processing device configured to control delivery of input-output operations from a host device to a storage system over selected ones of a plurality of paths through a network. The processing device is further configured to identify whether operational information of the host device corresponding to a given write input-output operation comprises one or more index nodes, and to analyze the one or more index nodes responsive to a positive identification. The processing device is also configured to determine whether one or more portions of data corresponding to the given write input-output operation comprise file data based on the analysis of the one or more index nodes, to encrypt at least part of the file data responsive to an affirmative determination, and to deliver the given write input-output operation comprising the encrypted file data to the storage system.
