Security
8-6 Modem 3600
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 regular user, then
request superuser privilege in order to clear the illegal attempts count.
If the local superuser disables security, the only security commands
available are those used to enable security or to check security status.
Passwords
Passwords can be changed or deleted by the superuser. The regular user
can change his password only if the “user changes” option has been
enabled by the superuser. Refer to the “Extended Features $W” section
on page 8-9 for more details.
When calling from a remote location, the user is prompted for a
password. After the password is entered, the user is either allowed direct
access or disconnected and called back depending on the assigned
security level.
During password entry or logon, each password character is displayed
as an X on the DTE screen. The backspace key can be used for editing.
For remote logon, press the Esc key at any time before pressing Enter
to clear the password entry.
Incorrect password attempts exceeding the threshold set in S77 for a
specific user will cause the modem to disconnect. Each call exceeding
the threshold increments the ILLEGAL ATTEMPTS counter by one.
