Adding security options
Security features can help to protect the server data and
programs from unauthorized access and use, and help to
physically protect the server from theft and tampering.
After you determine the system security needs, you can
activate or implement the appropriate security features.
To control access to the information in the server
databases, you can implement security measures through
the system configuration programs. These features
include defining two levels of password protection,
restricting diskette access, and defining a system owner's
name. Implementing these security measures helps you to
ensure the integrity of the data and programs that are
stored in the server. See “System security” on page 27
for details.
To prevent writing to a diskette in a diskette drive, set the
diskette write-protect switch, as described in “Diskette
write-protect switch setting” on page 147.
To erase lost or forgotten passwords, you can move the
CMOS clear (password) jumper on the system board.
To control access to other hardware components in the
server, you can install several types of optional devices.
These options include:
Ÿ
U-bolt
Ÿ
Security cable
Ÿ
Padlock
The following section discusses these security options.
Installing a U-bolt and security cable:
You
can help to deter unauthorized removal of the Netfinity
3000 server by installing a U-bolt and security cable on the
rear of the server. After you add the security cable, make
sure that it does not interfere with other cables that are
connected to the server.
Note
Ÿ
Obtain the following:
– A 19 mm (3/4 in.) U-bolt or wire rope
(similar to National Manufacturing No. 3230,
Stock No. 176-735)
– Threaded nuts that fit the U-bolt
– A security cable
– A lock, such as a combination lock or
padlock
Ÿ
Read “Safety information” on page 212.
