Dell Products L.P., Hopkinton, MA, has been assigned a patent (12277222) developed by Don; Arieh, Newton, MA, Ferrari; Michael, Douglas, MA, and Randolph; Benjamin, Uxbridge, MA, for “using snapshots for anomaly detection.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A profile of characteristics of a normal snapshot of a storage object is computed from previous snapshots of the storage object. Characteristics of a new snapshot are compared with the characteristics in the profile to identify an anomaly indicative of a malicious attack. The characteristics include percent data changed between consecutive snapshots, write LBA dispersion, write data reducibility, number and size of writes, write workload profile, and write content profile. The new snapshot is only vaulted or air-gapped if all its characteristics are within ranges defined by the profile.”
