22. Security Levels The Modem 3600 provides three levels of security to prevent unauthorized access by a remote user Level 1 Password Only This is the lowest level of dial up security The user dialing in is prompted for an ID and password if invalid the modem hangs up Level 2 Password with Callback This security level also accepts only calls from preset telephone numbers After the user enters a correct ID and password the modem looks up the telephone number and calls the user back at that number Level 3 Password with Callback and Password Re Entry This is the highest level of security and is similar to Password with Callback except that after the user answers the callback call the modem prompts again for the password Modem 3600 8 5 Security Superuser The superuser has access to all user information for administrative purposes and can change user logon requirements and privileges Superuser status can be gained at the local modem or from a remote modem via remote configuration if the Remote Superuser option is enabled The superuser must first logon as a regular user then request the superuser privilege Incorrect attempts to gain superuser privilege are logged in the user s status information field in nonvolatile memory After seven invalid attempts the user is suspended from access to the Modem 3600 until cleared by the superuser To reinstate a suspended user logon as a different regu
