| Supports binding a VPC-based TencentDB to a security group | Security groups can be bound with TencentDB and other relevant products. You can bind a security group with TencentDB instances. A security group is a stateful virtual firewall that provides data packet filtering. It can be used to set network access control for instances such as CVMs and ENIs, and also supports network access control for TencentDB instances in VPCs. Therefore, a security group can effectively enhance the security of TencentDB. | Binding instances with security groups |
| VPCs and security groups supports operation audit | VPCs and security groups support CloudAudit, which can obtain the historical records of API calling under your Tencent Cloud account, including API calling via the Tencent Cloud console, Tencent Cloud SDK, command line tool, and other Tencent Cloud services. This means that any deployment behavior on Tencent Cloud is monitored, and you can find out the sub-users and collaborators who use Tencent Cloud APIs, the source IP addresses from which the APIs are called, and when they are called. | — |
