What measures does DDS take to ensure data security
DDS is a virtual private cloud, which ensures that the instance is safely isolated from other services.
Why use DDS in the VPC
Security: Deploying DDS in VPC can provide greater security. VPC provides network isolation and access control, which restricts database instance from being visible only to specific VPC or subnet, thereby reducing the risk of exposure to the Internet.
Performance: Deploying DDS in VPC can achieve better performance. VPC provides low latency network connectivity, allowing application to quickly communicate with database instance, thereby improving response speed and throughput.
Isolation: You can use VPC to isolate the DDS in the private network, so that other cloud resources or VMs do not directly access the database, avoiding resource contention and interference, so as to improve the stability and reliability of database.
How to ensure the security of DDS when running in VPC
Network isolation deploys DDS in the private network, restricting database instance to be visible only to specific private network or subnet, avoiding public network exposure and reducing the risk of external attacks.
Does DDS support the option of creating an IPV6 subnet
Currently, you cannot select a subnet from the IPV6 CIDR block, so we recommend that you create and select the subnet from the IPV4 CIDR block.
How to import root certificates in Windows and Linux operating systems
Import into Windows operating system
Log in to the DDS console, click Instance Management, click the instance ID that requires a certificate to access the basic information, and click Download Certificate.
Import into Linux operating system
You can use any terminal connection tool (such as WinSCP and PuTTY) to upload the certificate to any directory on the Linux system.
