System Overview 1-9
Security Features
The system has hardware, software, and mechanical security features that offer
protection against unauthorized access to the system and data. The following
security features are available:
„
Password Security
The BIOS Setup utility includes a feature that allows a user to set either a
user or supervisor password, or both.
The user password controls booting of the system and controls access to
the BIOS Setup utility and the keyboard. User access to the BIOS Setup
utility is limited when a supervisor password is set. The supervisor
password allows full access to the system and the BIOS.
The unattended start security feature, when enabled, allows the system to
boot but locks the keyboard until the user password is entered.
See Section 2, “System Configuration,” for further information on setting
and using passwords and the unattended start feature.
„
Secure mode
Secure mode prevents keyboard or mouse input and unauthorized use of
the front panel power switch. A hot-key combination can be used to enter
secure mode quickly. The diskette drive can also be write-protected when
secure mode is set.
„
Windows Network Security Features
The Windows Network Security features are available through the
Windows operating system. Check the Windows documentation for
details.
„
Chassis Intrusion Notification
Whenever the chassis cover is removed, the BMC logs the incident.
See Section 2, “System Configuration,” for information on the chassis
intrusion notification feature.
„
Security slot
The security slot on the back of the chassis accepts a Kensington
®
Security Standard connector or other locking device. The locking device
secures the workstation to an immovable object to prevent theft.
„
Locking Tab
The system also has a locking tab on the rear of the chassis. The tab fits
through a slot on the rear edge of the chassis cover when the cover is on.
When a padlock is used in the tab, the system is physically protected
from chassis intrusion.
