A. On the Linux gateway, install a custom UDP listener and a script that extracts the XML fragments, then forwards these raw XML strings to XSIAM via a Syslog Data Collector. The XSIAM Data Flow then uses parse_xml().

B. On the Linux gateway, use a packet capture tool (e.g., Wireshark/tshark) to extract the binary payloads, then develop a custom CIPython program to parse the proprietary header/footer and XML, finally converting it to CEF and pushing it to an XSIAM Syslog Data Collector.

C. Configure the Linux gateway with a IJDP listener that stores the raw binary packets as files. The XSIAM Data Collector is then configured to monitor the gateway's file system, and the XSIAM Data Flow attempts to parse the binary content directly using parse_regex() on the raw binary data.

D. Implement a custom service on the Linux gateway to listen for UDP, extract the XML, transform it into a normalized JSON format, and then send it to XSIAM using the XSIAM HTTP Data Collector endpoint. The XSIAM Data Flow then uses parse_json().

E. Deploy a dedicated XSIAM Data Collector on the ICS network segment to directly receive the UDP logs, bypassing the Linux gateway, and use advanced XSIAM parsing features to decode the proprietary binary protocol.
