Monitor SCTP Security

Monitor SCTP traffic by viewing logs, ACC displays generated from SCTP logs, and predefined and custom reports.
You can enable SCTP association start logs and end logs for SCTP endpoints configured in a Security policy rule from an SCTP Protection profile. All other SCTP traffic logs are event-based logs that are generated based on the options you enable in the SCTP Protection profile.
To help you monitor SCTP traffic, the firewall uses the SCTP logs to create a visual display on the Mobile Network Activity tab in the ACC. The firewall also gives you predefined reports and the ability to generate custom reports.
View the SCTP logs to verify that your SCTP Protection profile settings are securing SCTP traffic as you intend and to see information on the wide range of SCTP attributes, including SCTP event type, chunk type, payload protocol ID, SCTP cause code, association ID, stream ID, and chunks, in addition to the general information that the firewall identifies, such as source and destination address, source and destination port, and timestamp. You can run predefined and custom reports on SCTP logs.
You must allocate a log storage quota for SCTP when you Configure SCTP Security before you can view SCTP log events.
  • View SCTP logs to see, for example, source and destination IP addresses of SCTP traffic, whether control chunks were allowed, whether data chunks were filtered by their PPID, and when SCTP associations started and ended.
