Why Oracle

China Southern Power Grid selected Oracle over other vendors, based on Oracle’s solid track record in database security solutions.

“As the world’s largest database solution supplier, Oracle has many years of technical expertise in data security,” said Chen Rui, database administrator, system maintenance center, enterprise information department, China Southern Power Grid. “Oracle Audit Vault and Database Firewall provides important reporting, warning, and compliance functions. It also has advanced, nonintrusive, ‘sniffer’ technology that enables rapid deployment without affecting production system architecture and database performance.

“The product constitutes a comprehensive solution for database audit and activity monitoring, which has enabled us to quickly identify, analyze, and monitor security flaws in key database transactions, such as the leakage of sensitive data and entry of malicious SQL script that may affect the database’s operation,” he added.

Implementation Process

Oracle Audit Vault and Database Firewall was deployed in August 2011 in China Southern Power Grid’s subsidiaries to monitor and audit the database activities of core business systems. The product was implemented within three weeks.


Oracle Specialized Partner Guangzhou Hua Pu Information Technology Co., Ltd. helped China Southern Power Grid build the data security platform based on Oracle Audit Vault and Database Firewall. During the project design phase, Guangzhou Hua Pu developed detailed design specifications, technical and work reports, and implementation plans.

During the implementation phase, Guangzhou Hua Pu installed the data security platform and provided China Southern Power Grid with installation and test reports, as well as operating instructions. During the project’s latter stages, Guangzhou Hua Pu developed the strategy update configuration file and the project’s summary report.  

“Guangzhou Hua Pu is an important system integrator for China Southern Power Grid and has undertaken the informatization [information and communications systems development in different regions], for construction projects of several systems and platforms,” said Chen. “Throughout this project, Guangzhou Hua Pu displayed professionalism, focus, and dedication. The company has introduced us to industrial-strength data security products and provided quality services.”
