Table 3. Software Security Features
Feature Description
Secure mode How to enter secure mode:
Setting and enabling passwords automatically places the system in secure mode.
If you set a hot-key combination (through the SSU or Setup), you can secure the
system simply by pressing the key combination. This means you do not have to
wait for the inactivity time-out period.
When the system is in secure mode:
The server can boot and run the operating system, but mouse and keyboard input is
not accepted until the user password is entered.
At boot time, if a CD is detected in the CD-ROM drive or a diskette in drive A, the
system prompts for a password. When the password is entered, the server boots
from CD or diskette and disables the secure mode.
If there is no CD in the CD-ROM drive or diskette in drive A, the server boots from
drive C and automatically goes into secure mode. All enabled secure mode
features go into effect at boot time.
To leave secure mode: Enter the correct password(s).
Disable writing to
diskette.
In secure mode, the server will not boot from or write to a diskette unless a
password is entered. To set this feature, use the SSU Security Subsystem Group.
To write protect access to diskette whether the server is in secure mode or not, use
the Setup main menu, Floppy Options, and specify Floppy Access as read only.
Disable the power
button.
Enable the feature through the SSU. Then the power button is disabled when the
server is in secure mode.
Set a time out period
so that keyboard and
mouse input are not
accepted.
Also, screen can be
blanked, and writes to
diskette can be
inhibited.
Specify and enable an inactivity time out period of from 1 to 120 minutes.
If no keyboard or mouse action occurs for the specified period, attempted keyboard
and mouse input will not be accepted.
The monitor display will go blank, and the diskette drive will be write protected
(if these security features are enabled through Setup or the SSU).
To resume activity: Enter the correct password(s).
Control access to
using the SSU: set
administrative
password.
To control access to setting or changing the system configuration, set an
administrative password and enable it through Setup or the SSU.
If both the administrative and user passwords are enabled, either can be used to
boot the server or enable the keyboard and/or mouse, but only the administrative
password will allow Setup and the SSU to be changed.
To disable a password, change it to a blank entry or press CTRL-D in the Change
Password menu of the Administrative Password Option menu found in the Security
Subsystem Group.
To clear the password if you cannot access Setup or the SSU, change the Clear
Password jumper (see Chapter 5).
