[ Introduction ] [ Tag structure ] [ How is the data sent to Devo? ] [ Table structure ]

Introduction

The tags beginning with cef0.mcas identify events in CEF format generated by Microsoft Cloud App Security.

Tag structure

Events in CEF format don't have a specific tag structure, as explained in Technologies supported in CEF syslog format. They are always sent to a table with the structure cef0.deviceVendor.deviceProduct.

In this case, the valid data tables are:

Tags	Data tables

Tags	Data tables
`cef0.mcas.siemAgent`	`cef0.mcas.siemAgent`
`cef0.mcas.siem_agent`	`cef0.mcas.siem_agent`
