6 Callback Security

 

 

Chapter6-CallbackSecurity

This chapter describes how to use callback security with your modem.

Callback security protects your network from unauthorized access and helps control long-distance costs. When callback security is enabled, all callers are requested to enter a password. If a valid password is received, the modem hangs up and returns the call by dialing a phone number that is stored with the password. The person being called back must then enter the password a second time to establish a connection.

Up to 30 callback passwords and dialing strings can be stored in the modem. Each dialing string can be up to 34 or 35 characters long and can contain commands as well as phone numbers. For mobile callers, the dialing string can be programmed to allow the caller to bypass the stored callback number by entering a temporary callback number, to enter an extension at the callback number, or to make a direct connection without callback.

For local security, the passwords and dialing strings that are stored in the modem are protected from tampering by a setup password, which you should change when you set up the modem. You can further protect the modem against tampering by disabling its ability to respond to most AT commands. To check for attempted break-ins, you can request the modem to display the number of failed password attempts.

Setup

Your modem was shipped with a default setup password (MTSMODEM). The same password is used for both callback security and remote configuration (Chapter 5). Because anyone who has ac- cess to this guide has access to the default password, you should change the password during your initial setup.

To Change the Setup Password

1.Open a data communications program such as HyperTerminal or PhoneTools.

2.In the terminal window, type AT#SMTSMODEM (or AT#Sxxxxxxxx if you have replaced the MTSMODEM password with xxxxxxxx) and press ENTER. The modem responds with OK if the setup password is correct, and ERROR if it is wrong.

3.To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and then press ENTER. The password can include any keyboard character, and can be up to eight characters long. The modem responds with OK.

4.The new password is saved automatically. You can now either enter more AT commands or exit the data communications program. The next time you wish to set up the modem, you must use the new password.

CAUTION: Passwords are case-sensitive. The next time you enter the password, it must be in the same case as you set it up.
