ModifySecurityGroupPolicies

Last updated: 2020-09-17 17:50:40

1. API Description

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

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

  • This API deletes all the existing egress and ingress policies, and then adds Egress and Ingress policies. It does not support custom indexes `PolicyIndex`.
  • For parameters of SecurityGroupPolicySet,
    • If `SecurityGroupPolicySet.Version` is set to 0, all policies will be cleared, and `Egress` and `Ingress` will be ignored.
    • If `SecurityGroupPolicySet.Version` is not set to 0, add `Egress` and `Ingress` policies:
      • `Protocol`: allows TCP, UDP, ICMP, ICMPV6, GRE, or ALL.
      • `CidrBlock`: a CIDR block in the correct format. In a classic network, if a `CidrBlock` contains private IPs 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.
      • `Ipv6CidrBlock`: an IPv6 CIDR block in the correct format. In a classic 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.
      • `SecurityGroupId`: ID of the security group. It can be the ID of security group to be modified, or the ID of other 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`: a single port number such as 80, or a port range in the format of '8000-8010'. You may use this field only if the `Protocol` field takes the value `TCP` or `UDP`.
      • `Action`: only allows ACCEPT or DROP.
      • `CidrBlock`, `Ipv6CidrBlock`, `SecurityGroupId`, and `AddressTemplate` are mutually exclusive. `Protocol` + `Port` and `ServiceTemplate` are mutually exclusive.

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
