Are you asking about syslog messages from the FMC itself (vs. events that you are sending to syslog)?

Generally speaking syslog severity settings include all messages of higher priority.

So telling a system to log at level 6 includes 0-5, 5 includes 0-4 etc.

  • 0 —emergency: System unusable.
  • 1 —alert: Immediate action needed.
  • 2 —critical: Critical condition
  • 3 —error: Error condition.
  • 4 —warning: Warning condition.
  • 5 —notification: Normal but significant condition.
  • 6 —informational: Informational message only.

Hi Marvin,

 

Now I have new problem feedback from client.

The problem is after I set to Info and also from Syslog output, I can have the output as below:

Syslog.Info

172.23.10.31

2020-08-12T03:34:29Z n206pdmzip1 IGMSSyslog1 %NGIPS-6-430003: DeviceUUID: 6c8a1040-fd69-11e6-afb6-cf5c4dcf2406, AccessControlRuleAction: Allow, SrcIP: x.x.x.x, DstIP: y.y.y.y, SrcPort: 51713, DstPort: 443, Protocol: tcp, IngressInterface: s1p3, EgressInterface: s1p4, IngressZone: IGMS-Outbound-to-PaloAltoFW, EgressZone: IGMS-Inbound-From CoreSW, ACPolicy: Default Intrusion Prevention, AccessControlRuleName: IGMS Prod Web Inline 2, Prefilter Policy: Unknown, User: No Authentication Required, Client: SSL client, ApplicationProtocol: HTTPS, ConnectionDuration: 6, InitiatorPackets: 9, ResponderPackets: 7, InitiatorBytes: 1250, ResponderBytes: 563, NAPPolicy: Inline Policy for Inline Interface, URL:xxxxxxxxxxxxxxxxxxxx.com

Syslog.Info

172.23.10.31

2020-08-12T03:37:15Z n206pdmzip1 IGMSSyslog1 %NGIPS-6-430003: DeviceUUID: 6c8a1040-fd69-11e6-afb6-cf5c4dcf2406, AccessControlRuleAction: Allow, SrcIP: a.b.c.d, DstIP: y.y.y.y, SrcPort: 43907, DstPort: 514, Protocol: udp, IngressInterface: s1p4, EgressInterface: s1p3, IngressZone: IGMS-Inbound-From CoreSW, EgressZone: IGMS-Outbound-to-PaloAltoFW, ACPolicy: Default Intrusion Prevention, AccessControlRuleName: IGMS Prod Web Inline 1, Prefilter Policy: Unknown, User: No Authentication Required, Client: syslog, ApplicationProtocol: syslog, ConnectionDuration: 21, InitiatorPackets: 4, ResponderPackets: 0, InitiatorBytes: 588, ResponderBytes: 0, NAPPolicy: Inline Policy for Inline Interface

 

However, I cannot see the output format come with Message or something like below table which is generate by Report Generator. May I have your advice how to set?

Is it something in the Syslog setup has to change ? Attach is it the option of the picture need to change? Right now it is set in Syslog.

The syslog message format cannot be modified.

It is not intended as a 1-1 replacement of the FMC reporting capability.

What is your client trying to do with the messages?

Hi Marvin,

 

Thanks to your reply.

 

My client shows the below one of example IPS Syslog which contains of Message (IPS signature information) and said why our one does not have that Message information. Below is his example:

 

For example:-
Intrusion Events will look like this below

Message: HI_CLIENT_BARE_BYTE  is signature name for this intrusion event.

<112>Aug 12 01:56:31 XXXX %NGIPS-0-430001: DeviceUUID: xxxxxxxxxxxxxxxxxxxx, SrcIP:x.x.x.x, DstIP: x.x.x.x, SrcPort: xxx, DstPort: xxx, Protocol: tcp, IngressInterface: s2p2, EgressInterface: s2p1, IngressZone: Internal, EgressZone: External, Priority: 3, GID: 119, SID: 4, Revision: 1, Message: HI_CLIENT_BARE_BYTE, Classification: Not Suspicious Traffic, User: No Authentication Required, IntrusionPolicy: TEST policy, TestACPolicy: Test Policy, NAPPolicy: Balanced Security and Connectivity

 

May I have your advise on any way to set the Firepower to display out this Message information?

 

I checked there is Facility setting as below, is it can help on this problem? Right now I am set it at Syslog. Is it any other setting or anything else beside this setting can help on this problem? Please advise. Thanks!

Hi Marvin,

 

I found out that the Syslog.info does not come with Intrusion Event as picture attached.

 

That is the problem that the Syslog does not come with the Message. This Message is the Intrusion Signature information on the Intrusion event.

 

May I get your help how to resolve on this? Thanks!
