The invention provides a data
storage security monitoring method and
system, and belongs to the field of data
storage security, and the method comprises the steps: carrying out the multi-dimensional statistical
feature extraction of historical operation
feature data of a storage
system, and constructing a historical security
feature vector set; real-time operation
feature data of the
system is obtained, multi-dimensional
semantic feature extraction is carried out, and a real-time security
feature vector set is generated; by innovatively adopting a metric learning
algorithm, the semantic distance between real-time and historical
feature vector sets is calculated, and the abnormal deviation degree of the system is accurately determined. Based on the abnormal deviation degree and a predefined
risk classification rule, the method dynamically evaluates the
risk level of the storage system. And when the
risk level reaches an early warning threshold value, the system automatically generates a
safety risk early warning and executes a corresponding grading risk relief operation according to the
risk level. According to the method, the security state of the storage system can be monitored in real time, potential risks can be actively identified, and the security protection capability of the
data storage system is improved.
