6/18 LS PRO OWNER'S HANDBOOK
Using the Security System
Chapter 6
On the other hand, a user can be forced to change his password
if the security configuration specifies a maximum password
lifetime. In this case, the Change Password dialog - retitled as
the Password Expired dialog - appears once the user’s password
has expired, whether or not the user requests it.
Unattended mode for Microsoft Windows
Temporarily unattended computers can pose a serious security
problem; a secure logon procedure is worthless if a ten-minute
coffee break can leave the whole system exposed. On the other
hand, it is inconvenient to have to turn off the computer for
only a short absence.
An optional enhancement to the security system offers an
“unattended mode” for the Microsoft Windows operating
system. When leaving the computer unattended for a time, a
user can click the button on his KeyLOC card to obscure the
screen and lock the keyboard and mouse; Windows continues
working “behind the scenes”. When the user returns, another
click of the button cancels unattended mode.
Unattended mode can be invoked and cancelled only by the
currently-logged-on user or by the Master user (provided that
they have KeyLOC cards).
Unattended mode requires a hardware upgrade (this may be
pre-installed), a Windows device driver, and a program called
LOC Saver for Windows. LOC Saver allows the user to select
a .BMP file with which to obscure the screen. The user can
specify an inactivity timeout too, so that LOC Saver will act
like a secure screen saver.
For more information, see the LOC Saver User's Guide.
