ENS:RevokeSecurityGroup

Last Updated:Mar 12, 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

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

There is currently no authorization information disclosed in the API.

Request parameters

ParameterTypeRequiredDescriptionExample
IpProtocolstringYes

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

  • tcp: TCP.
  • udp: UDP.
  • icmp: ICMP.
  • gre: 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:
