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.
