Problem description :

Flood log triggered by DoS Protection could not be sent to syslog server.

paloalto deploy: v-wire mode

PANOS : v4.1.8

Settings in paloalto :

1. Device -> Server Profiles -> Syslog -> Add a syslog server with port 514 and LOG_USER facility.

2. Objects -> Log Forwarding -> Add a syslog forwarding profile, all severity(Informational, Low, Medium, High and Critical) under threat settings are set syslog profile.

3. Objects -> DoS Protection -> Add a flood , type 'classified', enable SYN Flood, UDP Flood, ICMP Flood, and Other IP Flood, those alarm rate and active rate is 10 packets/sec.

4. From trust to untrust zone and untrust to trust zone security policy, apply default antivirus profile and log forward to syslog server.

5. Add a DoS Protection policy, from trust to untrust zone, set protect action, and Classified enabled, choose flood profile set in step3, Address choose 'source-ip-only'.

6 commit all settings.

Testing :

1. A client in trust zone, access eicar virus test file, the eicar test file deny log could be viewed in paloalto Monitor -> Logs -> Threat and in syslog server.

2. A client in trust zone, use 'hping' tool to generate tcp flood, the tcp flood log could be viewed in paloalto Monitor -> Logs -> Threat, but syslog is nothing.

Could flood log triggered by DoS Protection not be sent to syslog server?

set your zone logging profile to enable logging for Zone Protection events to syslog (or other log forwarding methods)
