You can call this operation to create an inbound security group rule. The created rule allows or denies the inbound traffic from other devices to the ECS instances in the security group to which the rule belongs.

Description

In the security group-related API documents, inbound traffic refers to the traffic sent by the source device and received at the destination device.

When you call this operation, take note of the following items:

  • The total number of outbound and inbound security group rules in each security group cannot exceed 200.
  • The priority (Priority) of a security group rule ranges from 1 to 100. A smaller value indicates a higher priority.
  • When multiple security group rules have the same priority, drop (drop) rules take precedence.
  • The source device can belong to a specified CIDR block (SourceCidrIp) or can be an ECS instance in another security group (SourceGroupId).
  • If the rule to be created matches an existing rule, the AuthorizeSecurityGroup operation succeeds but no rule is created.
  • You can determine a security group rule by specifying one of the following groups of parameters. You cannot determine a security group rule by specifying a single parameter.
    • Parameters used to determine an inbound security group rule that controls access from a specified CIDR block: IpProtocol, PortRange, SourcePortRange (optional), NicType, Policy, and SourceCidrIp. For a security group of the classic network type, you can set the NicType parameter to internet or intranet. For a security group of the VPC type, you can set the NicType parameter only to intranet. Sample request:
      
              https://ecs.aliyuncs.com/?Action=AuthorizeSecurityGroup
              &SecurityGroupId=sg-F876FF7**
              &SourceCidrIp=10.0.0.0/8
              &IpProtocol=tcp
              &PortRange=22/22
              &NicType=intranet
              &Policy=accept
              &<Common request parameters>
              
    • Parameters used to determine an inbound security group rule that controls access from another security group: IpProtocol, PortRange, SourcePortRange (optional), NicType, Policy, SourceGroupOwnerAccount, and SourceGroupId. To create an inbound security group rule to control access from another security group, you can set the NicType parameter only to intranet. For mutual access between security groups of the classic network type, you can allow or deny another security group in the same region access to your security group. The security group that is allowed access to your security group can belong to your own Alibaba Cloud account or another Alibaba Cloud account specified by the SourceGroupOwnerAccount parameter. For mutual access between security groups of the VPC type, you can allow or deny another security group in the same VPC access to your security group. Sample request:
      
              https://ecs.aliyuncs.com/?Action=AuthorizeSecurityGroup
              &SecurityGroupId=sg-F876FF7**
              &SourceGroupId=sg-1651FBB**
              &SourceGroupOwnerAccount=test@aliyun.com
              &IpProtocol=tcp
              &PortRange=22/22
              &NicType=intranet
              &Policy=drop
              &<Common request parameters>
