One or more aspects of the present disclosure relate to protecting the integrity of datasets stored by a storage array. In embodiments, one or more IO write requests from an input/output (IO) workload are intercepted. Additionally, a likely cyber-attack event is identified based on a bit density of write data corresponding to the one or more IO requests. Further, the cyber-attack event is mitigated.

Encryption detection

One or more aspects of the present disclosure relate to establishing and using a hybrid synchronous/asynchronous communication layer for input/output (IO) messages to a storage array. In embodiments, an input/output (IO) message can be modified into first and second IO portions. In addition, a network communications layer can be established to include synchronous and asynchronous channels. Further, the first IO portion can be transmitted over the synchronous channel, and the second IO portion can be transmitted over the asynchronous channel.

Synchronous/asynchronous network communications layer

Embodiments of the present disclosure include receiving one or more input/output (IO) requests at a storage array from a host device. Furthermore, the IO requests can include at least one data replication and recovery operation. In addition, the host device's connectivity access to a recovery storage array can be determined. Data replication and recovery operations can be performed based on the host device's connectivity to the recovery storage array.
