Abstract
Cyber-attacks on data maintained by a storage node are detected by monitoring for suspicious IOs to storage objects that contain only stable data. Data may be inherently stable or become stable based on elapsed time since the most recent update. Suspicious IOs to stable data storage objects include WR IOs that update stable data and, potentially, large-scale RD IOs. Metadata associated with storage objects is scanned to identify stable data storage objects and monitor for suspicious IOs. Further, stable data storage objects can be created by separating stable data from dynamic data, e.g., moving old data to a storage object that contains only old data. Exceptions are made for WR IOs that update metadata when processing small-scale RDs.
