unauthorized client access attempts, time of
This system does not support an encrypted/secured protocol; therefore, it is possible for a criminal hacker to ‘‘spoof’’ the system by reverse engineering the protocol and then ‘‘impersonating’’ a valid DEFINITY LAN Gateway client.
This is more likely to occur if the hacker has physical access to the Ethernet LAN or to a system attached to the Ethernet LAN that supports the DEFINITY LAN Gateway. Customers are encouraged to help protect the system and reduce the possibility of toll fraud occurring by attaching the system assembly and its clients to an isolated, physically secure Ethernet (not connected to any other Ethernet).
