Considering Security
Because a remote connection to the server is made through a dial-up modem, consider
any security that might be required. When you use a dial-up modem that has a direct-dial
number for access, anyone with a Hayes-compatible modem can dial the VP modem and
attempt to access the SMT. Therefore, Octel suggests that the modem telephone line be
an extension, with no direct outside access.
Use responsible networking procedures by disconnecting from the server after each
transaction or session. If you terminate a session incorrectly or incompletely, the
communication path remains open and is vulnerable to unauthorized access for
approximately 10 minutes. For additional security, install a black-box interception
device that detects carrier drop and immediately logs out of the SMT port.
Checking the Major Tasks
Refer to the following checklist for the major tasks required for setting up a remote
terminal or PC for remote system management. This checklist points you to the section
that describes the task in detail.

Remote system management is performed by either a
remote terminal or a PC equipped with
terminal-emulation software.
