Cisco IP Telephony Security Token Advisory
Used for Cisco CallManager and Cisco IP Phone authentication, the Cisco Security Administrator Security Token (SAST), a hardware device, contains a certificate that the Cisco Certificate Authority issues. You use a minimum of two security tokens when you configure the Cisco CTL client, a Cisco CallManager application that supports authentication. To use the security tokens with the Cisco CTL Client, you must install the Cisco CTL client on a single Windows 2000 workstation/server or Windows XP machine that has a USB port. After you complete the Cisco CTL client configuration, the security tokens create and sign the Certificate Trust List (CTL) file, a list of trusted entities that support authentication.
Caution Cisco requires a minimum of two security tokens for Cisco CTL client configuration. If you want to do so, purchase additional security tokens and immediately add the tokens to the CTL file. If you need to update the CTL file for any reason, you must use one security token that exists in the file.
Cisco recommends that you store the security tokens in a location that you will remember. If you want to do so, keep one security token in the USB port at all times.
For more information on the security token, authentication, and the Cisco CTL client, refer to Cisco CallManager security documentation that posts to the web.
Cisco Security Administrator Security Token (SAST) USB has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, Cisco encourages the user to try to correct the interference by one of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment to an outlet on a circuit different from the one to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician
Modifications not expressly approved by the manufacturer could void the user authority to operation the equipment under FCC rules.
All of the preceding warning applies also to the Cisco Security Administrator Security Token (SAST).
