Citrix Presentation Server allows remote users to work off a network server as if they weren't remote. That means: Incredibly fast access to data and applications for users, no third party VPN connection, and no latency issues. All of these features make Citrix Presentation Server a great tool for increasing access and productivity for remote users. Unfortunately, these same features make Citrix just as dangerous to the network it's running on. By definition, Citrix is granting remote users direct access to corporate servers?..achieving this type of access is also the holy grail for malicious hackers. To compromise a server running Citrix Presentation Server, a hacker need not penetrate a heavily defended corporate or government server. They can simply compromise the far more vulnerable laptop, remote office, or home office of any computer connected to that server by Citrix Presentation Server. All of this makes Citrix Presentation Server a high-value target for malicious hackers. And although it is a high-value target, Citrix Presentation Servers and remote workstations are often relatively easily hacked, because they are often times deployed by overworked system administrators who haven't even configured the most basic security features offered by Citrix. "The problem, in other words, isn't a lack of options for securing Citrix instances; the problem is that administrators aren't using them." (eWeek, October 2007). In support of this assertion Security researcher Petko D. Petkov, aka "pdp", said in an Oct. 4 posting that his recent testing of Citrix gateways led him to "tons" of "wide-open" Citrix instances, including 10 on government domains and four on military domains.

Microsoft hails the latest version of its flagship server operating system, Windows Server 2008, as "the most secure Windows Server ever". However, to fully achieve this lofty status, system administrators and security professionals must install, configure, monitor, log, and troubleshoot a dizzying array of new features and tools designed to keep the bad guys out and maintain the integrity of their network servers. This is no small task considering the market saturation of Windows Server and the rate at which it is attacked by malicious hackers. According to IDC, Windows Server runs 38% of all network servers. This market prominence also places Windows Server at the top of the SANS top 20 Security Attach Targets. The first five attack targets listed in the SANS top 20 for operating systems are related to Windows Server. This doesn't mean that Windows is inherently less secure than other operating systems; it's simply a numbers game. More machines running Windows Server. More targets for attackers to hack.As a result of being at the top of the "most used" and "most hacked" lists, Microsoft has released a truly powerful suite of security tools for system administrators to deploy with Windows Server 2008. This book is the comprehensive guide needed by system administrators and security professionals to master seemingly overwhelming arsenal of new security tools including: 1. Network Access Protection, which gives administrators the power to isolate computers that don't comply with established security policies. The ability to enforce security requirements is a powerful means of protecting the network.2. Enhanced solutions for intelligent rules and policies creation to increase control and protection over networking functions, allowing administrators to have a policy-driven network.3. Protection of data to ensure it can only be accessed by users with the correct security context, and to make it available when hardware failures occur.4. Protection against malicious software with User Account Control with a new authentication architecture.5. Increased control over your user settings with Expanded Group Policy....to name just a handful of the new security features. In short, Windows Server 2008 contains by far the most powerful and complex suite of security tools ever released in a Microsoft Server product. Securing Windows Server 2008 provides system administrators and security professionals with the knowledge they need to harness this power.

The polygon-mesh approach to 3D modeling was a huge advance, but today its limitations are clear. Longer render times for increasingly complex images effectively cap image complexity, or else stretch budgets and schedules to the breaking point. Comprised of contributions from leaders in the development and application of this technology, Point-Based Graphics examines it from all angles, beginning with the way in which the latest photographic and scanning devices have enabled modeling based on true geometry, rather than appearance. From there, it’s on to the methods themselves. Even though point-based graphics is in its infancy, practitioners have already established many effective, economical techniques for achieving all the major effects associated with traditional 3D Modeling and rendering. You’ll learn to apply these techniques, and you’ll also learn how to create your own. The final chapter demonstrates how to do this using Pointshop3D, an open-source tool for developing new point-based algorithms.

Tuning of SQL code is generally cheaper than changing the data model. Physical and configuration tuning involves a search for bottlenecks that often points to SQL code or data model issues. Building an appropriate data model and writing properly performing SQL code can give 100%+ performance improvement. Physical and configuration tuning often gives at most a 25% performance increase. Gavin Powell shows that the central theme of Oracle10gR2 Performance Tuning is four-fold: denormalize data models to fit applications; tune SQL code according to both the data model and the application in relation to scalability; create a well-proportioned physical architecture at the time of initial Oracle installation; and most important, mix skill sets to obtain the best results.
