The Security Gateway is a firewall for dial-up phone access. It provides a barrier against unauthorized access to any RS-232 device. It can be used in a dial-back mode with up to 240 numbers and passwords. These passwords are stored in battery backed memory and are secure against tampering by jumpers. The number of tries can be controlled so protection against “dictionary hacking” is exceptionally good. SG232 Pic

When the Monitor Mode is enabled, the Security Gateway will generate reports of attempts both successful and unsuccessful. This will alert the system operator of attempted access by unauthorized users.

The Security Gate can also be used without the dial-back feature to secure host ports from unauthorized access by in house communications lines or a terminal server configuration port.
