This handler uses the AWS REST API to Remove one or more ingress rules from a security group. The values that you specify in the revoke request (for example, ports) must match the existing rule's values for the rule to be removed. Each rule consists of the protocol and the CIDR range or source security group. For the TCP and UDP protocols, you must also specify the destination port or range of ports. For the ICMP protocol, you must also specify the ICMP type and code. Rule changes are propagated to instances within the security group as quickly as possible. However, a small delay might occur. This handler implements a subset of the full AWS call (single rule submission only). For more information see the AWS Amazon Virtual Private Cloud User Guide online.
The Dry Run parameter validates user permissions and inputs. If it is set to true, an error will always be thrown by the handler before completing the handler action. Error response will be 'DryRunOperation' if the account has proper permissions and inputs; 'UnauthorizedOperation' if the account does not have proper permissions.
