Creating a Security Group

마지막 업데이트 시간:2024-10-22 15:54:30

Operation Scenario
A security group is a virtual firewall for CVM instances. Each CVM instance must belong to at least one security group. Tencent Cloud provides two templates: Open all ports to the Internet and Open ports 22, 80, 443, and 3389 and ICMP protocol to the Internet. With these templates, you can create a default security group when creating a CVM instance if you have not yet created a security group. 
If you do not want your CVM instance to join the default security group, you can create another security group in the CVM console as follows:
Steps
1. Log in to CVM Console.
2. In the left sidebar, click Security Group to enter the security group management page.
3. On the security group management page, choose Region and click +Create.
4. In the Create a security group window that appears, complete the configuration, as shown in the following figure:
﻿
Template: based on the services to be deployed for the CVM instances in the security group, select an appropriate template to simplify security group rule configuration, as described in the following table:
