But security is the foremost concern of anyone providing such a service. Any server experiences casual probe attempts dozens of time a day, and serious break-in attempts with some frequency as well.\u003c\/p\u003e\n\u003cp\u003eThis highly regarded book, originally titled \u003ci\u003eBuilding Secure Servers with Linux\u003c\/i\u003e, combines practical advice with a firm knowledge of the technical tools needed to ensure security. The book focuses on the most common use of Linux--as a hub offering services to an organization or the Internet--and shows readers how to harden their hosts against attacks. An all-inclusive resource for Linux users who wish to harden their systems, \u003ci\u003eLinux Server Security\u003c\/i\u003e covers general security such as intrusion detection and firewalling a hub, as well as key services such as DNS, the Apache Web server, mail, and secure shell.\u003c\/p\u003e\n\u003cp\u003eAuthor Michael D.

RAID offers two benefits to these essential systems: improved I\/O performance and fail-safe data storage.\u003c\/p\u003e\n\u003cp\u003eAlthough bandwidth problems on networks are well documented, the internal data transfer bottleneck that exists at the hardware level in each system can also leave you with perplexing performance issues. RAID is a cost-effective and easy-to-manage way to alleviate this bandwidth problem by distributing the I\/O load seamlessly across multiple disks and controllers.\u003c\/p\u003e\n\u003cp\u003eRAID also provides uninterrupted data access through disk mirroring and parity algorithms. That means systems can remain online even during a disk or controller failure. RAID is scalable, making it robust enough for large, high-traffic sites and small, critical systems. By using RAID, system administrators can combine single disks into terabytes worth of data storage.\u003c\/p\u003e\n\u003cp\u003e\u003ci\u003eManaging RAID on Linux\u003c\/i\u003e covers everything system administrators need to know to put together a system that can support RAID.  You will learn about the different types of RAID, along with associated technologies and issues, and how to choose the best RAID system for your needs. With a step-by-step, hands-on approach, the author guides you through the installation of either Linux software RAID or a hardware RAID card. The book shows how to build an array and optionally install a high-performance file system.
