Callback Types

• Pass-through: Uses only user ID and password verification.

• Fixed callback: Uses a fixed, predefined callback phone number from the Callback Security

database after user ID and password verification.

• Variable callback: Uses either a callback phone number entered by the user, or a fixed,

predefined callback phone number from the callback security database after user ID and

password verification.

Security Types

• Pass-through: This type of security requires a user to perform a normal login procedure (that

is, to provide his or her user ID and password) before access to the host is permitted. The user

is given a preset number of login attempts, which the system administrator sets in the

Security

Defaults

dialog box. If a user is unsuccessful, the line is disconnected and a fault event is

recorded. This eliminates the possibility of a hacker, randomly generating passwords, to have

adequate time to chance upon a valid password.

• Fixed callback: This type of security requires a user to perform a normal login procedure (that

is, to provide his or her user ID and password) before access to the host is permitted. The user

is given a preset number of login attempts, which the system administrator sets in the

Security

Defaults

dialog box. The system then disconnects and calls back the user at the callback phone

number listed in the security database. A hacker who has managed to obtain a legitimate

password and user ID would not be able to gain access to the system because he or she would

not be at the legitimate callback number.

• Variable callback: This is the most useful type of security for your frequent travelers or laptop

users, such as sales representatives, claims agents, and repair technicians. This method works

like fixed callback, except that the user is prompted for the callback phone number at his or her

present

location. If your user presses ENTER when prompted for the phone number to call back,

variable callback assumes that the user is at the fixed callback location, and automatically calls

the user at the callback phone number listed in the security database.

Note: You can use the Callback Blacklist command to prevent callback to a phone number or a

range of numbers. See the online Help.
