Attack from the external network	Set up firewall.
Illegal login attempt to the manager host	Control login access to the manager host for users other than the administrators for the machine and JP1 products.

Illegal login attempt to JP1/IM - Manager	Prevent eavesdropping on the communication between JP1/IM - View and JP1/IM - Manager by setting up a VPN or by other means.
