    Ransomware Protection Storage in the Electric Power Industry

    Build the last line of defense for power data security.

Power Data Security Is Fundamental

From generation, transmission, and transformation to distribution, consumption, and dispatching, today's electric power enterprises are in the business of data. Indeed, data has become the core asset of the industry, only heightening the threat of data blackmail to the security and stability of power grids.

  • Energy Safety

    Tampering with key data — from monitoring and warning information to the operational instructions of key nodes — can causepower system faults or major security incidents.
  • Reputational Damage

    The exposure of sensitive information causes damage to an enterprise's reputation.
  • Economic Loss

    According to an IBM report in 2020, the average cost of data breaches in the energy industry is US$6.39 million each incident.
  • Service Interruption

    Malicious encryption of a database paralyzes power company services.

Ransomware Attacks in the Electric Power Industry

why1 pc

Electric power enterprises and infrastructure are the focus of attacks.

why2 pc

The double extortion model increases the risk of data breach.

why3 pc

Ransomware as a Service (RaaS).

why4 pc

The supply chain becomes the main entry point for extortion attacks.

why5 pc

Advanced Persistent Threat (APT)-like ransomware attacks.

why6 pc

The new normal of insecure data.


From primary storage to backup, Huawei's Ransomware Protection Storage Solution provides four layers of protection, better securing the data assets of electric power customers.

Layer 1

Ransomware detection and interception on production storage

Layer 2

Second-level recovery using secure snapshots on production storage

Layer 3

Hour-level fast recovery on local backup storage

Layer 4

Fast recovery using secure data in isolation zone protected by Air Gap Tech

E2E Data Encryption

Protocol-layer encryption NFS, CIFS/SMB.
Advanced Encryption Standard (AES)-256 encryption of production and backup data.
Encryption during air gap replication.
Encryption during remote replication of data and copies.

Air Gap Replication

By setting the replication Service Level Agreement (SLA), data copies are automatically and periodically replicated from the production or backup storage to the isolation environment. The replication link is active only during replication, which ensures data copies are offline most of the time, reducing the possibility of attacks.

File System WORM and Secure Snapshot

A protection period can be set for production or backup data to prevent data modification or deletion during this time range.
Secure snapshots ensure storage data is read-only and cannot be modified or deleted within a specified time range.

Ransomware Detection

A baseline model is established based on historical data to check for any abnormalities in the changed feature values of the metadata of copies.
Abnormal copies are further compared to determine file size changes, entropy values, and similarities.
The Machine Learning (ML) model is used to determine whether file changes are caused by ransomware encryption, flagging them accordingly.
