How to include timezone in syslog forwarded Guardium events

Troubleshooting


Problem

Guardium events forwarded through remote syslog process do not include timezone information, events not showing up under appropriate time filter in your SIEM, or event time displayed in SIEM is few hours off .

Symptom

You may notice Guardium events not showing up under appropriate time filter in your SIEM even though the payload has the correct time. Or you may notice the event time displayed in SIEM is few hours in the past or future than the event time stated in the payload.

Cause

Out of the box Guardium appliance use RSYSLOG_TraditionalFileFormat template to write timestamp. This uses default log file format with low-precision timestamps and does not include timezone information. As a result your SIEM may use a different timezone misrepresenting the event time.

Resolving The Problem

Guardium appliance syslog daemon needs to be configured to use RSYSLOG_FileFormat template for timestamp. This is a modern-style logfile format similar to TraditionalFileFormat, but with high-precision timestamps and timezone information.

Please contact IBM Support to have this changed, and reference this article.
