Carrier Access 1750 Manual De Usuario

This notice summarizes relevant security concerns associated with the movement of 
sensitive data through any Broadmore ATM Multiplexer and subsequent re-
deployment of these products into open environments. Should there be any questions 
or concerns regarding this notice, please contact Carrier Access Corporation customer 
support at 800-786-9929.

The modules used in the Broadmore each contain one or more of the following 
types of non-volatile memory: removable Disk-on-Chip, removable and non-
removable Flash memory. There is no internal data path or mechanism provided in 
a Broadmore to permit network data streams to be recorded onto non-volatile 
media. Such unintended or hostile actions on the part of the Broadmore could only 
be enabled by the surreptitious alteration of the device’s embedded firmware and 
hardware. Thus, adequate physical security and access controls are required to 
prevent hostile implementation of “other” (non-Carrier Access provided) firmware 
and hardware.

).

When operated 

properly, this version of software contains “zeroize” commands that reformats the 
Disk-on-Chip and destroys all stored configuration and sensitive data. It also 
contains a start-up routine that verifies that no surreptitious software has been 
loaded.  See the Broadmore/SSHield Management Module Security Policy for 
more information.

The Broadmore also has a limited amount of cell buffering implemented via 
random access memory (RAM). This memory implementation is entirely volatile 
and will be immediately lost upon power-down.  Data that has been buffered in the 
Broadmore RAM cannot be recovered under any circumstances after power-down.
