What format does the ePO server use to write to database tables?

• A. JSON
• B. Syslog
• C. Common Events Format (CEF)
• D. CSV

Answer: (C)

The events that the ePO server writes into its database are stored using a standardized event format, specifically the Common Event Format (CEF). This format provides a consistent structure for security-related data, with a header that includes fields like deviceVendor, deviceProduct, deviceVersion, eventClassID, name, and severity, plus optional extensions for additional details. Using CEF makes it easier to index, search, and correlate events across different sources and to integrate with SIEMs or other analysis tools, because all events share a common schema.

JSON, Syslog, and CSV aren’t the internal write format used by ePO for database tables: JSON is a data interchange format, Syslog is a logging transport protocol, and CSV is a flat, export-oriented format. They may be used for exporting or forwarding in different contexts, but they aren’t the standard internal format for how ePO formats events written to its database.
