Book Review: File System Forensic Analysis

  • Unix Review; By Kristy Westphal (Posted by tuxchick on Oct 31, 2005 7:21 AM EDT)
  • Story Type: Reviews
Before I even had this book in my hands, I was truly excited about it. I have used Autopsy and The Sleuth Kit for some time now in my forensic work, and I am a big fan. These free tools are straightforward and critical to any forensic investigation. Brian Carrier, the author of File System Forensic Analysis, also created these tools, so when I saw that he wrote an entire book on file systems, I was pumped! Who better than Carrier to detail a topic that has been sparsely documented?

The Hercules System/370, ESA/390, and z/Architecture Emulator

The web site reads: "Hercules is an open source software implementation of the mainframe System/370 and ESA/390 architectures, in addition to the new 64-bit z/Architecture. Hercules runs under Linux, Windows 98, Windows NT, Windows 2000, Windows XP, and Mac OS X 10.2 and later."

It runs best on Linux and it helps shops without mainframe access port their software to Linux on the S/390 and zSeries platforms.

Answering Microsoft: Comments on Microsoft's Letter to MA

As most readers probably know, Massachusetts has chosen the OpenDocument standard as their standard for office suite data exchange. Massachusetts has published the comments about this decision from many sources, including Adobe, Corel, IBM, Microsoft, and Sun Microsystems. Microsoft was extremely unhappy that the OASIS OpenDocument standard was selected instead of their proprietary XML format, aka the Microsoft Office Open XML format, that is under development.

Pamela Jones asked me to comment in more depth on Microsoft’s response, because I’ve had past related experience (e.g., with standards, XML, and even OpenDocument specifically). Many people have made brief comments about this letter, but she thought a more detailed commentary would help those who are less familiar with this topic. So, here’s my attempt at commenting on Microsoft’s letter in more detail.

[ED.- A very long, but thorough rebuttal of Microsoft's anti-ODF FUD, complete with references. A must read, especially if you're a government, or any other organisation concerned about your who controls your own documents!]

Hardware emulation with QEMU

  • NewsForge (Posted by dave on Oct 31, 2005 6:30 AM EDT)
  • Story Type: News Story
QEMU is an open source cross-platform emulator for Linux hosts. It allows you to emulate a number of hardware architectures (x86, x86-64, and PowerPC are currently known to work, with others, including SPARC and MIPS, in development). QEMU thereby lets you run another operating system on top of your existing OS. Going through the process of installing and configuring QEMU not only gave me a worthwhile new software tool, but also helped me learn a few things about Linux.

Ellison, Old Friends in Software Showdown

  • Yahoo News; By Michael Liedtke (Posted by tuxchick on Oct 31, 2005 6:23 AM EDT)
  • Story Type: News Story
Oracle Corp. CEO Larry Ellison knows all about battles with old friends. After all, Oracle just pulled off high-profile takeovers of PeopleSoft Inc. and Siebel Systems Inc. - a pair of rival software makers run by former subordinates who turned against him. Now, Ellison is straddling another set of fractured friendships in a drama unfolding around Salesforce.com Inc. and NetSuite Inc.The pioneering upstarts - conceived by a younger generation of Ellison's corporate progeny - have been helping steer the business software industry in a new direction with applications that are accessed directly over the Internet.

Once considered a crazy idea, the concept of online, or "on-demand," software has turned into a hot market as thousands of companies decide they would rather lease applications monthly than pay an upfront licensing fee and then deal with the costs - and headaches - of installation, maintenance and the inevitable software upgrades.

The Sky(pe) is falling

Robert Vamosi writes: ...it didn't surprise me to read last week that a new buffer overflow vulnerability was found within the very popular Skype VoIP service. But what will make or break VoIP will be how this very young industry handles emerging security issues and whether the public eventually puts its trust in the new technology. Judging by the way Skype has handled its recent vulnerabilities, I think the prognosis is good for VoIP in the long run.

[A positive prognosis for Skype and VoIP, generally speaking. Oh what fun it is to defend your Skype calls from Internet-based attacks! - Ed]

Software Firewalls versus Wormhole Tunnels

  • Security Focus; By Bob Rudis and Phil Kostenbader (Posted by tuxchick on Oct 31, 2005 5:26 AM EDT)
  • Story Type: News Story, Security
In a VPN configuration, most personal firewalls are configured to drop their shields (because all traffic is heading to and from a trusted source), so the VPN client is, in fact, a liability because there is no need to use a libpcap outbound wormhole-tunnel communications channel. The firewall will happily ignore whatever packets a malicious program might need and they go unfiltered through the "secure" VPN connection... Creating and using a wormhole-tunnel communications channel is not limited to malicious use by malware, spyware, viruses or worms. The following scenario illustrates how one can legitimately (and more robustly) bypass the firewall without the use of libpcap.

[Ed.- and don't forget email, web browsers, and all the ways that SSH can sneak around firewall rules.]

Oregon Governor Announces New Open Source Technology Initiative by ...

Red Hat Readies for Government Scrutiny

"There have been a couple of runs at trusted operating systems in the past, but the difference between what's out there now and what we're announcing is that, in the Linux world, we'll have trusted capabilities in a standard distribution," said Paul Smith of Red Hat.

A Look at Trolltech and Qt 4

  • KDE Dot News; By Jonathan Riddell (Posted by dcparris on Oct 31, 2005 2:06 AM EDT)
  • Story Type: News Story; Groups: KDE
Jonathan Riddell writes: "Two recent articles cover the success of Trolltech and their product Qt 4, on which KDE 4 will be based. Trolltech: A case study in open source business looks at the continued growth of the company based on dual licenced Free Software. The article describes what KDE and Trolltech gain from each other, including user feedback to Trolltech and sponsored developers for KDE. The Australian Computerworld declairs that Qt 4 raises the bar for cross-platform app dev tools. They cover the separate modules of Qt 4 and the cross-platform quality, giving it a 9.2 out of 10 approval rating."

[As pointed out in the KDE News post, the Computer World article erroneously refers to software in the public domain. This stuff has been around for over 22 years. Seems like professionals in the field would have some concept of this by now. - Ed]

Modern Memory Management

  • OnLamp.com; By Howard Feldman (Posted by tuxchick on Oct 31, 2005 1:37 AM EDT)
  • Story Type: Tutorial
Despite this enormous increase in memory capacity, many of the problems that exist on today's machines are the same as those of their early predecessors--namely, running out of memory.

This article, the first in the series, discusses the Unix dynamic memory allocation system along with the concept of memory segmentation. It also reviews the utilities top and ulimit, giving special attention to their role in memory management. Memory management is an important concept to grasp regardless of which programming language you use. You must be most careful with C, where you control all memory allocation and freeing. Languages such as C++, Java, Perl, and PHP take care of a lot of the housekeeping automatically. Nevertheless, all of these languages and others can allocate memory dynamically, and thus the following discussion applies to them all

I talked with McClellan recently and learned a lot about where IBM and its business partners will be investing time and energy in the near future and what 2006 might look like.
