Abstract: Techniques are provided for authenticating communications between physical ports using knowledge of shared secrets. One method comprises receiving, by a first entity, a connection request to establish a communication between physical ports of the first entity and a second entity; providing a first pseudo-random value to the second entity; obtaining a shared secret for communications with the second entity; generating a first hash value based on the shared secret and the first pseudo-random value; obtaining a second hash value from the second entity based on the shared secret and the first second pseudo-random value; and authenticating the communication in response to the first entity validating the first hash value using the second hash value. An encryption key based on the shared secret can protect communications between the physical ports of the first and second entities.

Abstract: Methods, apparatus, and processor-readable storage media for managing initiator identities are provided herein. An example computer-implemented method includes monitoring one or more port identifiers used by respective ones of a plurality of host initiators for accessing one or more storage components of a storage system; detecting, based on the monitoring, anomalous behavior of at least a first one of the host initiators, wherein the detecting comprises identifying that the first host initiator is using at least one same port identifier as a second one of the host initiators to access a particular one of the storage components; and performing at least one automated action in response to the detecting.

Abstract: Methods, apparatus, and processor-readable storage media for protecting data based on a context of data movement operations are provided herein. An example computer-implemented method includes identifying a context of a data movement operation based at least in part on a source and an indicated destination of data associated with the data movement operation; applying one or more data protection policies to the data movement operation based at least in part on the identified context, wherein a given data protection policy comprises one or more indications of one or more content scanners that are configured to detect data belonging to one or more regulated data classes; and in response to detecting data associated with the data movement operation that belongs to at least one of the regulated data classes, performing one or more automated remedial actions associated with the at least one regulated data class.

Abstract: Methods, system, and non-transitory processor-readable storage medium for distributed and multi-level server authentication are provided herein. An example method includes receiving, by a plurality of second servers, a plurality of authentication secret slices, where a first server transmits each of the plurality of authentication secret slices to a respective second server of the plurality of second servers, receiving, by the first server, an authentication confirmation from each of the plurality of second servers and confirming, by the first server to a client, that an authentication request has succeeded.

Abstract: Data access threat detection and prevention modules are implemented proximate to data storage, e.g. in disk array controllers. The modules may be implemented in hardware or firmware. The modules monitor IOs from the disk array controllers to access managed drives. IOs exhibiting access parameters that deviate from a whitelist or match a blacklist are deemed to be suspicious. The whitelist may be created from monitoring normal, safe IOs and storing associated access patterns. In response to detection of suspicious activity the modules may halt or slow subsequent IOs, e.g. IOs to the same data, all data, an associated logical device, or the managed drive.

Abstract: A method, computer program product, and computing system for monitoring a high-availability storage system for the occurrence of a failure event from which the high-availability storage system automatically recovered. The failure event is associated with a failure event cost. A party associated with the high-availability storage system is informed of the failure event cost.

Abstract: Methods, apparatus, and processor-readable storage media for determining migrations between geographically distributed data centers are provided herein. An example computer-implemented method includes obtaining information associated with data centers that are geographically distributed relative to one another, wherein the information includes: information related to migration factors specific to the respective geographic location of each of the data centers and information related to a respective set of processes of each of the data centers; automatically generating a migration schedule based at least in part on the obtained information, wherein the migration schedule comprises one or more times for migrating at least one of the processes of a first one of the data centers to a second one of the data centers; and automatically triggering at least one migration of the at least one process between the data centers based at least in part on the migration schedule.
