ApsaraDB for OceanBase:Create a DataHub data source

Security risks

You can choose to automatically or manually add public CIDR blocks for the data transmission service, but security risks exist. Your use of the data transmission service indicates that you have understood and acknowledged the possible security risks. You must take basic security protection measures, such as setting a complex password for your account, limiting the open port numbers of CIDR blocks, enabling authentication for communication among internal APIs, and regularly check for and limit CIDR blocks that are not required.

The data transmission service will add or delete the CIDR blocks automatically added to a whitelist or security group based on business needs and security risks. Do not use the CIDR blocks in a whitelist or security group for business needs other than the data transmission service. If you use such CIDR blocks for other business needs, the issues thus incurred are beyond the guarantee scope of the SLA of the data transmission service. For more information about how to add an IP address to a whitelist or security group for the data transmission service, see Add a whitelist.
