Security group, an instance-level firewall provided by Tencent Cloud, is used to control inbound/outbound traffic of CVMs.

  1. Log in to the CVM console, and click Security Group in the left navigation pane.
  2. Click the New button, enter the security group name (e.g. my-security-group), select Template or Custom, and then click OK after confirming inbound and outbound rules.
  3. Click the Add an Instance button on the right of the security group list, and select the CVM to be associated with the security group to complete the process.


You can also enter the CVM list page to view or modify the security group associated with a CVM. On the CVM list page, select the CVM for which you want to modify the security group, and click More -> Configure Security Group on the right side, and then select a security group for association.
(For example, to allow your local computer (IP: to send HTTP requests to the CVM, you can create a rule as shown in the figure below.)
