a rogue modem is a modem that is connected to a workstation or server and usually can be dialed without permission from security or IT. If a computer with a rogue modem is connected to your organization’s network, anyone with a little computer skill and malicious intent can use that modem to access your network. Firewalls don’t protect against this type of attack. The intruder gains access via phone lines, bypassing the firewalls that protect your organization’s network borders
