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.
Electric power enterprises and infrastructure are the focus of attacks.
The double extortion model increases the risk of data breach.
Ransomware as a Service (RaaS).
The supply chain becomes the main entry point for extortion attacks.
Advanced Persistent Threat (APT)-like ransomware attacks.

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.
The Huawei Ransomware Protection Storage Solution covers Storage Area Network (SAN), Network-Attached Storage (NAS), and backup storage scenarios. Key technologies — including storage encryption, air gap, secure snapshot, and WORM — are used to implement data anti-tampering, security detection, and secure recovery.
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.
