1. Introduction

The SRM-100 Secure Rack Modem is designed for applications that require secure, dial-up access to console ports on rack mounted equipment. WTI's Secure Rack Modem can recognize up to 100 passwords, and track activity for each password and create a log record of successful and/or unsuccessful access attempts.

Password Protected Access

Up to 100 passwords can be stored in the SRM's non-volatile memory. Each password can be assigned a user name for easy reference, and an optional Dial Back number which instructs the unit to call the user at a predefined number before allowing access to the secure device. A separate System Password restricts access to the SRM command mode, this allows the system administrator to contact the unit via modem in order to change parameters or check access activity.

Access Activity Logs

The SRM-100 provides two convenient ways to track access activity; the Audit Log and the Password Directory. The Audit Log lists the 100 most recent connection attempts, including the time, date, password entered, port used, call duration, and reason for disconnect. The Password Directory displays user names, passwords and dial back numbers, and counts use of each individual password. The Audit Log and Password Directory can only be viewed by the System Administrator; callers who log on with a User Password are not allowed to view these screens.

Three Different Operating Modes

The SRM-100 provides three distinct operating modes; the User Mode, the Command Mode, and the Unsecured Mode.

User Mode: Provides password protected access to the secure device connected to the SRM's serial modem port.

Command Mode: Provides password protected access to the SRM Command Menus, which are used to define passwords and select configuration parameters.

Unsecured Mode: When this mode is activated, the SRM will function like a normal, unsecured modem; callers are allowed to access the secure device without entering a password.

Features

Password Protected Command Mode

Recognizes Up to 100 User-Defined Passwords

Tracks Access Attempts and Password Activity

Requires Only One 19 Inch Rack Unit.
