Traffic logs filter on syslog

L2 Linker

Hello team,

 

We are sending all the traffic logs to our inhouse syslog servers. So whatever traffic is matching current security policies, all such traffic logs are forwarded to syslog server. Now in those logs, i am seeing everything like Source, Destination, port everything. Now our requirement, we need to send only specific logs to syslog for specific traffic. e.g. dont want to disclose source IP. How can i configure this? 

 

Pls suggest.

@johnde,

 

I think you are looking for FILTER BUILDER under  Log Forwarding Profiles. By default, it select 'All Logs' under Filter. But you can create custom filter as per your requirement. PFB snap for your ref. Once you create Filter, attach that Log Forwarding Profile to required security policies.

 

Hope it helps!

Hi @johnde ,

 

What @${userLoginName} mentions will work and is very granular.

 

If you want to customize for your syslog-server you can also do this:

Goto your syslog server profile on the Device tab. There's a Custom Log Format tab ... click the Traffic one :

Add the field you want :

@${userLoginName} ,

 

Thanks Mayur, i will try it.

@kiwi hey, thanks much! I will try this also. 

 

Will keep you posted.

Yes, this is very helpful when you have multiple syslog servers and you want to filter specific logs fields for specific syslog server only.

@kiwiThanks for sharing this too.
