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.
SCTP logs are event-based logs that include information on a 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. The SCTP logs also provide additional information on some applications running over SCTP, including Diameter and SS7 protocols. View the SCTP logs to verify that your SCTP Protection profile settings are securing SCTP traffic as you intend.
