Download or read book The Book of Xen written by Chris Takemura and published by No Starch Press. This book was released on 2010 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Xen allows administrators to run many virtual operating systems on one physical server, including Linux, BSD, OpenSolaris, and Microsoft Windows. In the process, users save money on hardware, maintenance, and electricity. Not only is Xen open source, the Xen hypervisor (the virtual machine monitor) is the best-performing hypervisor available. "The Book of Xen" explains everything a sysadmin needs to know to use this powerful technology, with coverage of installation, networking, virtualized storage, and managing guest and host operating systems. Written for administrators who have worked with *NIX before but who may be new to virtualization, "The Book of Xen" covers both the basics and the trickier aspects of Xen administration, like profiling and benchmarks, migration, XenSource administration, and hardware assisted virtualization (HVM).

Download or read book Network Flow Analysis written by Michael Lucas and published by No Starch Press. This book was released on 2010 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed and complete guide to exporting, collecting, analyzing, and understanding network flows to make managing networks easier. Network flow analysis is the art of studying the traffic on a computer network. Understanding the ways to export flow and collect and analyze data separates good network administrators from great ones. The detailed instructions in Network Flow Analysis teach the busy network administrator how to build every component of a flow-based network awareness system and how network analysis and auditing can help address problems and improve network reliability. Readers learn what flow is, how flows are used in network management, and how to use a flow analysis system. Real-world examples illustrate how to best apply the appropriate tools and how to analyze data to solve real problems. Lucas compares existing popular tools for network management, explaining why they don't address common real-world issues and demonstrates how, once a network administrator understands the underlying process and techniques of flow management, building a flow management system from freely-available components is not only possible but actually a better choice than much more expensive systems.

Available in PDF, EPUB and Kindle. Book excerpt: Capacity Management is described in most key ITSM frameworks: ITIL, ISO 20000 Microsoft Operations Framework (MOF) and the Application Service Library (ASL) all note the importance of Capacity Management. This major title meets the need for an in-depth practical guide to this critical process. Written and reviewed by some of the world’s most respected experts in this field it shows how Capacity Management best practice can support provision of a consistent, acceptable service level at a known and controlled cost.

Download or read book Virtualization for Security written by John Hoopes and published by Syngress. This book was released on 2009-02-24 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the biggest buzzwords in the IT industry for the past few years, virtualization has matured into a practical requirement for many best-practice business scenarios, becoming an invaluable tool for security professionals at companies of every size. In addition to saving time and other resources, virtualization affords unprecedented means for intrusion and malware detection, prevention, recovery, and analysis. Taking a practical approach in a growing market underserved by books, this hands-on title is the first to combine in one place the most important and sought-after uses of virtualization for enhanced security, including sandboxing, disaster recovery and high availability, forensic analysis, and honeypotting. Already gaining buzz and traction in actual usage at an impressive rate, Gartner research indicates that virtualization will be the most significant trend in IT infrastructure and operations over the next four years. A recent report by IT research firm IDC predicts the virtualization services market will grow from $5.5 billion in 2006 to $11.7 billion in 2011. With this growth in adoption, becoming increasingly common even for small and midsize businesses, security is becoming a much more serious concern, both in terms of how to secure virtualization and how virtualization can serve critical security objectives. Titles exist and are on the way to fill the need for securing virtualization, but security professionals do not yet have a book outlining the many security applications of virtualization that will become increasingly important in their job requirements. This book is the first to fill that need, covering tactics such as isolating a virtual environment on the desktop for application testing, creating virtualized storage solutions for immediate disaster recovery and high availability across a network, migrating physical systems to virtual systems for analysis, and creating complete virtual systems to entice hackers and expose potential threats to actual production systems. About the Technologies A sandbox is an isolated environment created to run and test applications that might be a security risk. Recovering a compromised system is as easy as restarting the virtual machine to revert to the point before failure. Employing virtualization on actual production systems, rather than just test environments, yields similar benefits for disaster recovery and high availability. While traditional disaster recovery methods require time-consuming reinstallation of the operating system and applications before restoring data, backing up to a virtual machine makes the recovery process much easier, faster, and efficient. The virtual machine can be restored to same physical machine or an entirely different machine if the original machine has experienced irreparable hardware failure. Decreased downtime translates into higher availability of the system and increased productivity in the enterprise. Virtualization has been used for years in the field of forensic analysis, but new tools, techniques, and automation capabilities are making it an increasingly important tool. By means of virtualization, an investigator can create an exact working copy of a physical computer on another machine, including hidden or encrypted partitions, without altering any data, allowing complete access for analysis. The investigator can also take a live ?snapshot? to review or freeze the target computer at any point in time, before an attacker has a chance to cover his tracks or inflict further damage.
