Can someone list the dangers of having modems installed in host PCs. These modems would have direct outside telephone connections.
These few PCs are part of a large firewalled network but firewall would not protect hacking via these modems/PC's.
What potential dangers are there to the network when:
- Modem is set to listen for incoming calls at all times.
- Modem is not set to listen for incoming calls but is host activated/used for specific outside comms (for example for sending faxes or specific dial-in to remote systems). Is there a danger whilst the modem is in use and whilst idle?
What else to look out for?
