1. API Description

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

This API (ModifySecurityGroupPolicies) is used to reset the egress and ingress policies (SecurityGroupPolicy) of a security group.

  • This API deletes all the current egress and ingress policies, and then adds new Egress and Ingress policies. It does not support custom PolicyIndex indexes.
  • If SecurityGroupPolicySet.Version is set to 0, all policies will be cleared, and Egress and Ingress will be ignored.
  • The value of the Protocol field can be TCP, UDP, ICMP, ICMPV6, GRE, or ALL.
  • The CidrBlock field allows you to enter any string that conforms to the CIDR format. (More details) In a basic network, if a CidrBlock contains private IP addresses on Tencent Cloud for devices under your account other than CVMs, it does not mean this policy allows you to access these devices. The network isolation policies between tenants take priority over the private network policies in security groups.
  • The Ipv6CidrBlock field allows you to enter any string that conforms to the IPv6 CIDR format. (More details) In a basic network, if an Ipv6CidrBlock contains private IPv6 addresses on Tencent Cloud for devices under your account other than CVMs, it does not mean this policy allows you to access these devices. The network isolation policies between tenants take priority over the private network policies in security groups.
  • The SecurityGroupId field allows you to enter the IDs of security groups that are in the same project as the security group to be modified, including the ID of the security group itself, to represent private IP addresses of all CVMs under the security group. If this field is used, this policy will change without manual modification according to the CVM associated with the policy ID while being used to match network messages.
  • The Port field allows you to enter a single port number, or two port numbers separated by a minus sign to represent a port range, such as 80 or 8000-8010. The Port field can be used only when the value of the Protocol field is TCP or UDP.
  • The Action field only allows you to enter ACCEPT or DROP.
  • CidrBlock, Ipv6CidrBlock, SecurityGroupId, and AddressTemplate are exclusive and cannot be entered at the same time. Protocol + Port and ServiceTemplate are mutually exclusive and cannot be entered at the same time.

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

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: vpc.ap-shanghai-fsi.tencentcloudapi.com
