A firewall for phone lines: plug this into your phone system’s “outermost permiter” — the place where your office phone system meets your telco’s local loops — and it will monitor incoming and outgoing calls. Why? So you can keep employees from compromising network security by plugging modems into their desk phones and providing a back-door to the network. You can tell the system which lines are allowed to send and receive what kinds of calls (data, voice, fax). While this is clearly a good idea securitywise, it does seem to play into Dilbertian power-fantasies of total control over your corporate infrastructure. Link Discuss (via Meerkat)
