-- Returns the security groups currently in effect for a mount target. This
-- operation requires that the network interface of the mount target has
-- been created and the life cycle state of the mount target is not
-- \"deleted\".
--
-- This operation requires permissions for the following actions:
--
-- -   'elasticfilesystem:DescribeMountTargetSecurityGroups' action on the
--     mount target\'s file system.
-- -   'ec2:DescribeNetworkInterfaceAttribute' action on the mount
--     target\'s network interface.
