Security

Certain features of the system can be protected by passwords to prevent

unauthorized users from abusing the system. You should assign passwords

wherever you can and limit knowledge of such passwords to three or fewer

people.

Nondisplaying authorization codes and telephone numbers provide another

layer of security. For more information, see Appendix A, “Customer Support

Information.”

Throughout this document, toll fraud security hazards are indicated by an

exclamation point inside a triangle and the words Security Alert.

Security Alert:

Security Alert indicates the presence of toll fraud security hazard. Toll

fraud is the unauthorized use of your telecommunications system by an

unauthorized party (e.g., persons other than your company’s employees,

agents, subcontractors, or persons working on your company’s behalf).

Be sure to read “Your Responsibility for Your System’s Security”

on the

inside front cover of this book and “Security of Your System: Preventing

Toll Fraud” in Appendix A, “Customer Support Information.”
