    ENS:RevokeSecurityGroup

    Last Updated:Dec 25, 2024

    Deletes an inbound security group rule. After the rule is deleted, the access control implemented by the rule is removed.

    Operation description

    • In the security group-related API documents, inbound traffic refers to the traffic sent by the source and received by the destination.
    • You can determine an inbound security group rule by specifying one of the following groups of parameters. You cannot determine a security group rule by specifying only one parameter.
    • You can specify one or more of the following parameters to remove access control for a CIDR block: IpProtocol, PortRange, Policy, and SourceCidrIp.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    IpProtocolstringYes

    The transport layer protocol. The value of this parameter is case-sensitive. Valid values:

    • tcp
    • udp
    • icmp
    • gre
    • all: all protocols.
    		all
    PortRangestringYes

    The range of destination ports that correspond to the transport layer protocol for the security group rule. Valid values:

    • When the IpProtocol parameter is set to tcp or udp, the port number range is 1 to 65535. The start port number and the end port number are separated by a forward slash (/). Correct example: 1/200. Incorrect example: 200/1.
    • When the IpProtocol parameter is set to icmp, the port number range is -1/-1, which indicates all ports.
    • When the IpProtocol parameter is set to gre, the port number range is -1/-1, which indicates all ports.
    • When the IpProtocol parameter is set to all, the port number range is -1/-1, which indicates all ports.
    		22/22
    SecurityGroupIdstringYes

    The ID of the security group.

    		sg-bp67acfmxazb4p****
    PolicystringNo

    The authorization policy. Valid values:

    • accept: allows access. This is the default value.
    • drop: denies access and does not return responses.
    		accept
    PriorityintegerNo

    The priority of the security group rule. Valid values: 1 to 100. Default value: 1.

    		1
    SourceCidrIpstringYes

    The source CIDR block. CIDR blocks and IPv4 addresses are supported. Default value: 0.0.XX.XX/0.

    		10.0.XX.XX/8
    SourcePortRangestringNo

    The range of source ports that correspond to the transport layer protocol for the security group rule. Valid values:

    • When the IpProtocol parameter is set to tcp or udp, the port number range is 1 to 65535. The start port number and the end port number are separated by a forward slash (/). Correct example: 1/200. Incorrect example: 200/1.
    • When the IpProtocol parameter is set to icmp, the port number range is -1/-1, which indicates all ports.
    • When the IpProtocol parameter is set to gre, the port number range is -1/-1, which indicates all ports.
    • When the IpProtocol parameter is set to all, the port number range is -1/-1, which indicates all ports.
