Assessing the Security of Your Web Applications
Dynamic content on web sites will continue to enhance the business functionality of web sites; it is supported by a growing number of e-commerce sites. Also, these web applications are increasingly connected to databases that were previously accessible only through internally built custom applications. Malicious individuals can exploit these web-based applications to gain access to privileged information. Several simple methods, such as cookie poisoning and forms manipulation, can be used to exploit poorly designed web applications; most often, just a text editor and a browser are sufficient. The tools used to execute the exploits are easily available and require minimal knowledge. The very same tools and methods may be used to test the robustness of web applications.
An exhaustive testing of web applications will require building test scenarios to identify vulnerabilities. Proper web-application designs, web-server configuration, secure programming practices and good housekeeping are necessary for the security of any web site and a site's privileged resources. Due to the custom nature of web applications, they pose a challenge to the security of web sites. In the future, web applications are expected to be more secure, as certified components used to build applications gain support. For now, we will have to rely on both static and dynamic testing of web applications.

Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
