1. API Description

Domain name for API request: vpc.intl.tencentcloudapi.com.

This API is used to create a security group, and add security group policies.

• For the the upper limit of security groups per project in each region under each account, see here
• For newly created security groups, the inbound and outbound policies are set to Deny All by default. You need to call CreateSecurityGroupPolicies
  to change it.

Description:

• Version: The version number of a security group policy. It automatically increments by 1 every time you update the security policy, so to prevent the expiration of the updated policies. If this field is left empty, any conflicts will be ignored.
• Protocol: Values can be TCP, UDP, ICMP, ICMPV6, GRE, and ALL.
• CidrBlock: Enter a CIDR block in the correct format. In the classic network, even if the CIDR block specified in CidrBlock contains the Tencent Cloud private IPs not used for CVMs under your Tencent Cloud account, it does not mean this policy allows you to access those resources. The network isolation policies between tenants take priority over the private network policies in security groups.
• Ipv6CidrBlock: Enter an IPv6 CIDR block in the correct format. In the classic network, even if the CIDR block specified in Ipv6CidrBlock contains the Tencent Cloud private IPv6 addresses not used for CVMs under your Tencent Cloud account, it does not mean this policy allows you to access those resources. The network isolation policies between tenants take priority over the private network policies in security groups.
• SecurityGroupId: ID of the security group. It can be the ID of a security group to be modified, or the ID of another security group in the same project. All private IPs of all CVMs under the security group will be covered. If this field is used, the policy will automatically change according to the CVM associated with the group ID while being used to match network messages. You don't need to change it manually.
• Port: Enter a single port number (such as 80), or a port range (such as 8000-8010). Port is only applicable when Protocol is TCP or UDP. If Protocol is not TCP or UDP, Protocol and Port cannot be both specified.
• Action: Values can be ACCEPT or DROP.
• CidrBlock, Ipv6CidrBlock, SecurityGroupId, and AddressTemplate are exclusive to one another. "Protocol + Port" and ServiceTemplate are mutually exclusive.
• Only policies in one direction can be created in each request. If you need to specify the PolicyIndex parameter, the indexes of policies must be consistent.

A maximum of 100 requests can be initiated per second for this API.
