Table 4. Software Security Features

Feature Description
Secure mode How to enter secure mode:
• Setting and enabling passwords automati cally places the system in secure
mode.
• If you set a hot-key combination (through 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 operat ing 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 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.
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).
To resume activity: Enter the correct password(s).
Control access to using
the SSU: set supervisor
password
To control access to setting or changing the system configuration, set a
supervisor password and enable it through Setup.
If both the supervisor and user passwords are enabled, either can be used to
boot the server or enable the keyboard and/or mouse, but only the supervisor
password will allow Setup to be changed.
To disable a password, change it to a blank entry or press CTRL-D in the
Change Password menu of the Supervisor Password Option menu found in the
Security Subsystem Group.
To clear the password if you cannot access Setup, change the Clear Password
jumper (see Chapter 6).
