Collect Tripwire logs

This document describes how you can collect the Tripwire logs by using a Google Security Operations forwarder.

For more information, see Data ingestion to Google Security Operations .

An ingestion label identifies the parser which normalizes raw log data to structured UDM format. The information in this document applies to the parser with the TRIPWIRE_FIM ingestion label.

Configure Tripwire Enterprise

1. Sign in to the Tripwire Enterprise web console using administrator credentials.
2. To edit the Log managementsettings, click the Settingstab.
3. Select Tripwire > System > Log management.
4. In the Log management preferenceswindow, do the following:
   1. Select the Forward TE log messages to syslogcheckbox.
   2. In the TCP hostfield, enter the Google Security Operations forwarder IP address or hostname.
   3. In the TCP portfield, enter the port on which the log messages are sent through TCP.
   4. To test the configuration, click Test connection.
5. To save the changes, click Apply.

Configure the Google Security Operations forwarder to ingest Tripwire logs

1. Go to SIEM Settings > Forwarders.
2. Click Add new forwarder.
3. In the Forwarder Namefield, enter a unique name for the forwarder.
4. Click Submit. The forwarder is added and the Add collector configurationwindow appears.
5. In the Collector namefield, type a name.
6. Select Tripwireas the Log type.
7. Select Syslogas the Collector type.
8. Configure the following mandatory input parameters:
   • Protocol: specify the connection protocol (TCP) that the collector uses to listen to syslog data.
   • Address: specify the target IP address or hostname where the collector resides and listens to syslog data.
   • Port: specify the target port where the collector resides and listens to syslog data.
9. Click Submit.

Field mapping reference

Overview: This parser extracts fields from Tripwire File Integrity Manager (FIM) syslog messages, normalizing them into the UDM format. It handles various log categories, including system events, security events, changes, and audits, mapping them to corresponding UDM event types and enriching the data with details like user information, affected resources, and security outcomes.
