ATI Drivers For Linux

The other day ATI released new linux drivers for their Radeon cards, complete with a new graphical installer. In the past, I have had nothing but gried with ATI drivers, never successfully getting 3D acceleration working. However, this time, once I went through the process and ran the configuration, when the display server restarted, and I loaded up Tuxracer (hey, everyone uses it as an indication on whether acceleration is working), what I got was smoothe graphics.

Now, if the same process that I used on my lab machine works on my home machine, I might not need to use Windows anymore.

On a side note, my Windows machine has been running for almost 2 months now with no major problems, but since Win2k support is being discontinued, I wonder how long that is going to last.

Review – Security Warrior

Security Warrior labels itself as the “most comprehensive, up-to-date book covering the art of computer war�?. Having been on my To-Read list since it was initially released a year and a half ago, I was interested to see how accurate this claim remains.

Obviously, some topics you might expect to be covered in a comprehensive security handbook are missing. No where to be seen is discussion of vulnerabilities in MD5 and SHA, as these hadn’t been published yet. Also missing is any reference to the Linux 2.6 kernel, as the first version of that was released barely a month before the first publishing.

However, this items discussed in this book are general enough that they are still valid and highly valuable. Discussion is platform neutral where possible, with further discussion on platform dependencies where needed. There are some very nice examples and case studies, which make the book a more interesting read than strict discussion. The Advanced Defense subsection is spectacular and well deserving of the designation Advanced. A lot of the ideas there, while simple in nature, are things that I haven’t come across before, or even thought of, especially their discussion on intrusion detection and log aggregation.
There are, however, a few problems with the book. First and foremost, I have a problem with the Social Engineering section. While I agree that social engineering is an important aspect of network security, 10 pages does not even begin to scratch the surface on the topic. Thankfully, this is offset by an amazing set of references at the end of the chapter, including the excellent “Art Of Deception�? by Kevin Mitnick. Another problem that ties into this, is the fact that the Reconnaissance chapter comes AFTER the Social Engineering chapter, when reconnaissance is usually a precursor to a social engineering attack. I felt that the logical order would have created a smoother reading process here. Finally, the author’s repeatedly mentioned that some tools were standard on Linux distributions, but not commercial unix systems, and as a result might have to be installed manually. I felt this repetition for most of the tools discussed was distracting from the core information I was trying to read.

One area that deserves its own discussion is the section on Reverse Engineering. This section was highly interesting, showing a wide variety of techniques for not only the Unix operating system, but Windows CE as well. A plethora of information regarding techniques, tips and tools are contained in these chapters……. but really only for the Unix and Windows CE environments. Out of 175 pages, only 20 of those discusses reverse engineering on the actual windows platform. With 2/5 of the book actually being devoted towards this topic, I feel that this section might have been better off being an entire book of its own, with expanded discussion for all environments and additional examples.

Overall, Security Warrior was quite an interesting read. I fully plan to take many concepts I have learned here and incorporate them into both current and future plans. If you want a detailed look at network security concepts, this book is a very solid starting point, before branching out into other works.

Final Rating: 3.5/5
