DNP3 Outstation Unsolicited Messaging Support
Medium Nessus Plugin ID 23810
SynopsisThe remote DNP3 outstation supports unsolicited response.
DescriptionThere are a variety of reasons why polling SCADA outstations may not provide adequate or timely information. To address this, DNP3 supports unsolicited response where the outstations initiate a response without a poll request when a threshold is exceeded or an event is triggered. The host has a DNP3 server that currently is configured to support unsolicited response.
SolutionDisable unsolicited response if it is not required.
