Sonicwall NSA 2400: Notification on intrusion events

Hi,

I've got a requirement to generate alerts (a phone call is requested but I could sell an email -> SMS) for intrusion events on our network.

We've got a Sonicwall NSA 2400. The approach that occurred to me is to enable and config Intrusion Prevention, enable Alert logging for the IP category, then a configure a send-to address for Alerts in Log > Automation.

The problem with this is that we're spamming a device with thousands of alerts for IP events. Ideally we are looking for a way to notify only in the case of a credible (or successful) attack.

Is there a better approach?

Thanks.

may be good to reference SonicOS logging granularity in term of SonicOS Category (like Intrusion
Detection, Firewall event), Legacy Category (like Attack) , Prioity Level (like Emergency, Alert, Critical),  and/or specific to Log Msg ID for trimming down the "spam". see the info and event type tbl in below

Log Redundancy Filter

 The Log Redundancy Filter allows you to define the time in seconds that the same log message is logged on the Log > View page as a single entry in the SonicWALL log. Various log messages are often rapidly repeated, which can quickly fill up a log if each attack is logged. The Log Redundancy Filter has a default setting of 60 seconds.

Alert Redundancy Filter

 The Alert Redundancy Filter allows you to define the time in seconds that the same alert is sent to the "Send Alerts to E-mail Address." The Alert Redundancy Filter has a default setting of 900 seconds.
