DoS dont send Syslog to Remote Highspeed logging server

Hello,

 

Anyone have issues with Remote High-Speed loging server and l4 DoS Sylog?

 

I have created under Security > Event Logs > Logging Profiles > RemoteLog > here I enable DoS Protection and I enabled network Firewall & DoS Protection with Local & Remote Publisher enabled. Application Security use Remote Storage > This works.

 

For Remote Publisher I create pool (same port & same server as for Application Security) and attached (tried with both ArcSight & Splunk) to Remote destination where I chose Pool server. Using tcpdump I only see Application Security Events but don’t see DoS started Syslog msg (in Web UI I see Dos started, I also get SNMP Alarm) , also I don’t get Network Firewall events like reject, accept (put this for test), …. Anyone have same issue?

    What version of the AFM are you using? Do you see Dos started/Stopped messages in /var/log/ltm?

     

  • Hi,

     

    Yes, in /var/log/ltm I have Jun 16 13:24:48 hostname err tmm[22308]: 01010252:3: A NETWORK /PARTITION/VSERVER_POLICY DOS attack start was detected for vector TCP SYN flood, Attack ID 1869164187.

     

    Version: 12.1.0 0.0.1434

     

    SNMP Trap also sent, but not Syslog.

     

    Also this new version do not write Brute Force detection under Events.

     

    All this with Syslog, SNTMP Traps, Event logging is a bit ...
