Audit events

A description of audit events in common event format (CEF).

Audit events in common event format (CEF) are in this format:
<134>Oct 10 2019 16:00:18 local-sg-19.x n2osevents[0]: CEF:0|Nozomi
Networks|N2OS|19.0.3-10201846_FD825|AUDIT:SESSIONS:CREATE|User signed in|0|
dvchost=local-sg-19.x

cs1Label=browser
cs6Label=n2os_schema
msg=User signed in

suser=admin

Note the highlighted part of the audit message. This is the Audit Type ID. This should be used as the key for performing searches once Nozomi Networks syslog events have been ingested into the integration platform.

Best practice

Make sure that your parsing logic extracts the appropriate data. If you are integrating with CEF messages, a CEF parser must be used. Do not use regular expressions. This will ensure the integration integrity in the future. When using the correct parser for the data that is expected, be sure to test different inputs to ensure that data is correctly extracted from the messages.
