Security Warrior by Cyrus Peikari and Anton Chuvakin
Security Warrior is, indeed, a dangerous book. Not so much for the specific tools and techniques it presents, as all of them can be found on the Internet, but because the book collects all this information in one convenient, easy-to-read volume. With a subtitle of “Know Your Enemy”, this book provides a powerful compilation of attacks against software, networks and individual systems.
Given that hundreds of security books are out there, I was a bit skeptical this one would live up to its claim of being so different. However, as soon as you enter the first section, “Software Cracking”, you know you are in for a different ride. After a quick refresher on assembly language, this section covers how to reverse engineer software in Windows, Linux and Windows CE, with the focus on how to crack malware such as viruses or spyware. I personally found this section a bit slow-going, but I did learn a good bit from it. I especially found the text on overflow attacks quite relevant, given the large number of such attacks around today.
For me, the book really hit its stride in the second section, “Network Stalking”. After a brief review of basic TCP/IP attacks and tools, the text dives into active and passive reconnaissance, OS fingerprinting and hiding an attack. Chapter 7, on social engineering, seems a bit out of place in this section, but it is an interesting read nonetheless. In later sections, I enjoyed the well-written chapters on hardening UNIX/Linux systems and UNIX/Linux attacks, which include information about breaking out of chroot jails that I hadn't seen in other security books.
My only minor complaint about the book is the editing is a little uneven. Most sections are well done, but in a few cases there are references to topics that “would be covered later” but never are. In another case, I felt there was unnecessary duplication of information. Overall, I found this book to be a strong text with a refreshingly different spin on computer/network security. If you are responsible for system or network security, Security Warrior is definitely worth reading.
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
