Hello all,
I am considering an evaluation of NowSMS and was curious to know how DoS attacks are handled - in particular not so much as to say how to mitigate issues from the gateway sending data to the webserver, but rather what to do in the event that too many messages are sent from devices/webpages/etc TO the gateway itself. Is there a way to limit what is sent from the same number, or anything else clever?

How about pre-processing a message that comes in so the gateway takes no action on it (doesn't go through the gateway), rather through some sort of script or something of that nature.

Thanks for your help,

Hi Mike,

The Pre-Auth SMS accounting callback could be implemented on your end to add this type of tracking/detection.

The link above needs to be updated, as for quite some time the pre-auth callback has included a "To=" parameter for recipient information, as well as "Text", "Data", "PID", "DCS" and "UDH" information.
