• protection development blocks: basics of Unix passwords, clients, teams, the Unix filesystem, cryptography, actual defense, and body of workers security.
• community safeguard: a close examine modem and dialup defense, TCP/IP, securing person community prone, Sun's RPC, a variety of host and community authentication platforms (e.g., NIS, NIS+, and Kerberos), NFS and different filesystems, and the significance of safe programming.
• safe operations: maintaining thus far in today's altering safety global, backups, protecting opposed to assaults, acting integrity administration, and auditing.
• dealing with defense incidents: researching a break-in, facing programmed threats and denial of carrier assaults, and criminal features of desktop security.
• Appendixes: a finished safeguard record and a close bibliography of paper and digital references for extra analyzing and research.
Packed with a thousand pages of worthy textual content, scripts, checklists, advice, and warnings, this 3rd version is still the definitive reference for Unix directors and a person who cares approximately preserving their platforms and knowledge from today's threats.

The operating system automatically detects when a USB device has been connected and automatically configures the operating environment to make it available. The Solaris 10 operating environment supports USB devices on Sun Blade, Netra, Sunfire, and x86/x64-based system. In addition, a USB interface can be added to Sun systems that may not already have one. When hot-plugging a USB device, the device is immediately displayed in the device hierarchy. For example, a full device pathname for a USB Zip drive connected to an Ultra system would appear as follows: /pci@1f,4000/usb@5/storage@1 A printer would look like this: /pci@1f,4000/usb@5/hub@3/printer@1 Be careful when removing USB devices, however.
Many questions on the exam refer to the various types of device names. • Practice all the commands and step by steps until you can describe and perform them from memory. The best way to memorize them is to practice them repeatedly on a Solaris system. • As with every chapter of this book, you'll need a Solaris 10 system on which to practice. Practice every step-by-step example that is presented until you can perform the steps from memory. Also, as you practice creating file systems, you'll need some unused disk space with which to practice.
Explain when and how to list and reconfigure devices. A computer typically uses a wide range of peripheral and mass-storage devices such as a small computer system interface (SCSI) disk drive, a keyboard, a mouse, and some kind of magnetic backup medium. Other commonly used devices include CD-ROM drives, printers, and various Universal Serial Bus (USB) devices. Solaris communicates with peripheral devices through device files or drivers. A device driver is a low-level program that allows the kernel to communicate with a specific piece of hardware.
