Is My Data Secure in GaussDB(DWS)?

Yes. In the big data era, data has become a core asset. The public cloud will adhere to the commitment made over the years that we do not touch your applications or data, helping you protect your core assets. This is our commitment to users and the society, laying the foundation for the business success of the public cloud and their partners.

GaussDB(DWS) is a data warehousing system with telecom-class security to safeguard your data and privacy. Moreover, the public cloud GaussDB(DWS) delivers carrier-class quality, which can satisfy data security and privacy requirements of governments, financial organizations, and carriers. Therefore, it is widely used by various industries. GaussDB(DWS) of the public cloud won the following security authentication:

  • Internal Cyber Security Lab (ICSL) in compliance with cyber security standards issued by the UK authorities.
  • Privacy and Security Assessment (PSA) to meet EU requirements of data security and privacy.

Service Data Security

GaussDB(DWS) is built on public cloud software infrastructure, including ECS and OBS. Both ECS and OBS won the Trusted Cloud Certification issued by the China Data Center Alliance in 2017.

Service data of GaussDB(DWS) users is stored in the ECSs in the cluster. Neither users nor public cloud O&M administrators can log in to the ECSs.

The operating system of ECSs is hardened for security, including kernel hardening, installation of the latest patch, permission control, port management, and protocol and port anti-attack.

GaussDB(DWS) provides complete security measures, such as password policies, authentication, session management, user permissions management, and database audit.

Snapshot Data Security

GaussDB(DWS) backups are snapshots stored in OBS. OBS has passed the China Data Center Alliance trusted cloud security authentication. OBS supports access permission control, key access, and data encryption features. GaussDB(DWS) snapshot data can be used for data backup and restoration only and cannot be accessed by any user. GaussDB(DWS) administrators can view the OBS space occupied by snapshot data on the GaussDB(DWS) console and public cloud bills.

Network Access Security

GaussDB(DWS) is fully isolated between the layer-2 and layer-3 networks to fulfill security requirements of government and financial users.

  • GaussDB(DWS) is deployed in the tenant-dedicated ECS environment, which is not shared with other tenants. Therefore, data leakage due to computing resource sharing is impossible physically.
  • ECSs in a GaussDB(DWS) cluster are isolated through VPCs, preventing the ECSs from being discovered and intruded on by other tenants.
  • The network is divided into the service plane and management plane. The two planes are physically isolated, ensuring network security.
  • The tenants can flexibly customize the security group and access rules.
  • External application software access GaussDB(DWS) over SSL.
  • Data imported from OBS is encrypted.
