Dale pak ale maji spolecny Target.Port, ktery ma spolecna i Dionaea, pokud vynechame Node.Type: Protocol:

Pokud chceme tedy do skatulky zaradit i Dionaea, pak je pravidlo pro SIP takto:
35
FILTER1: "filter": {"$and": [{"Category" : "Attempt.Exploit"}, {"Node.Type": {"$eq": "Honeypot"}}, {"Target.Port" : 5060 }]}
36
Chceme-li pouze vyse uvedene, pak je skatulka takto:
37
FILTER2: "filter": {"$and": [{"Category" : "Attempt.Exploit"}, {"Node.Type": {"$eq": "Honeypot"}}, {"Node.Type": {"$eq": "Protocol"}}, {"Target.Port" : 5060 }]}
