I have already deployed a fax server and am about to deploy a backup system for this host at our off-site facility. It struck me that I have given no thought to securing the serial port to unauthorized access. The modem is a Multi-Tech MT5634ZBA which supports data as well as fax. So this poses the same type of risk, if not to the same degree, as an ssh or telnet port but without the availability of a firewall to throttle repeated unsuccessful connection attempts. Are there any recommendations on what should be done in this circumstance or am I fretting unduly? Regards, -- *** E-Mail is NOT a SECURE channel *** James B.
