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: U-bolt Security cable 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 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 Read "Safety information" on page 212.
