Security group is a virtual firewall for filtering packets and is used to set the network access controls for one or multiple CVMs. It is an important network security isolation method provided by Tencent Cloud. When creating a CVM instance, you must configure a security group for it. Tencent Cloud allows you to configure a new security group for the CVM instance after it is created.
Note:
To configure a new security group for the instance, create a security group first. For more information, please see Creating a Security Group.
