Which method is used for third-party network data consumption?

The Common Event Format (CEF) via broker Syslog module is the correct choice for third-party network data consumption because CEF is specifically designed to standardize the format of events for easy integration and processing of logs from various sources. This format facilitates the integration and sharing of event information between different systems and tools, making it highly effective for handling network data.

The Syslog protocol is widely utilized for sending log or event messages to a server, and using the CEF format within a Syslog module enhances compatibility with numerous security information and event management (SIEM) systems. This flexibility is crucial when integrating data from various third-party network devices, enabling efficient parsing and analysis of logs across different platforms and applications, which is essential for maintaining security and monitoring network activity effectively.
