Virtualization is the New Web Browser

I read the first post by the president of VMware, Diane Greene. She discusses a subject that has been gnawing at my brain since I heard that Microsoft began offering Virtual Server as a free download. Ms. Greene makes two points. First, she promotes VMware's Virtual Machine Disk Format (VMDK) as an open alternative to Microsoft's Virtual Hard Disk Image Format Specification (VHD). I would obviously like to see an open standard prevail against a closed one.

Second, she argues discusses "the question of whether virtualization should be tightly integrated into the operating system or instead a separate wholly independent layer." As you might guess she wants separation: "Tight integration comes at the unfortunate cost of giving up bias-free choice of operating system and thus software stack (i.e. OS and application program)."

This is the Web browser-in-the-OS argument all over again. Microsoft said last year that "Microsoft will build virtualization capabilities into the Windows platform based on Windows hypervisor technology, planned for availability in the next product wave of the Windows operating system, code-named Windows 'Longhorn.' This integrated hypervisor technology in the Windows operating system will be designed to provide customers with a high-performance virtualization solution for Windows and heterogeneous environments."

Everyone's doing it. Check out Red Hat's initiatives, which include integrating Xen into Fedora Core 5. FreeBSD is also bringing Xen into its source tree, probably for FreeBSD 7.0 but maybe 6.2.

You might also consider virtualization to be like a TCP/IP stack. I remember installing Trumpet Winsock on Windows 3.1 so I could dial-in to the Internet in the early 1990s. Now every OS ships with a TCP/IP stack.

With word that Microsoft Virtual Server 2007 is delayed until 2007, like Vista and Office 2007, the only question is Microsoft's ability to execute. I consider VMware to be the leader in the virtualization space. Will there come a day, however, when I'll just use the built-in virtualization technology on Windows instead of adding a third-party product? Maybe. Then again, I'm posting these ideas in Firefox -- not IE.

Unfortunately, it all eventually comes down to economics. How long can an open source product be viable without "selling out" or going commercial? Once you go commercial, and especially if you go public, the rules change, the products change, the focus changes, and most importantly, grassroots perception changes.

Browser integration wars, OS wars, virtualization wars, Yahoo and then Google and whatever the next best one will be...so many things are cool when still not profitable, but yet become these evil entities once they became products of the profit machine.

Nevertheless, I'll likely end up using both Virtual Server from Microsoft to keep up on technology on the professional side, but use VMWare in my personal endeavors.

Zeek in Action Videos

Image
This is a quick note to point blog readers to my Zeek in Action YouTube video series for the Zeek network security monitoring project .  Each video addresses a topic that I think might be of interest to people trying to understand their network using Zeek and adjacent tools and approaches, like Suricata, Wireshark, and so on.  I am especially pleased with Video 6 on monitoring wireless networks . It took me several weeks to research material for this video. I had to buy new hardware and experiment with a Linux distro that I had not used before -- Parrot .  Please like and subscribe, and let me know if there is a topic you think might make a good video.

MITRE ATT&CK Tactics Are Not Tactics

Image
Just what are "tactics"? Introduction MITRE ATT&CK  is a great resource, but something about it has bothered me since I first heard about it several years ago. It's a minor point, but I wanted to document it in case it confuses anyone else. The MITRE ATT&CK Design and Philosophy document from March 2020 says the following: At a high-level, ATT&CK is a behavioral model that consists of the following core components: • Tactics, denoting short-term, tactical adversary goals during an attack; • Techniques, describing the means by which adversaries achieve tactical goals; • Sub-techniques, describing more specific means by which adversaries achieve tactical goals at a lower level than techniques; and • Documented adversary usage of techniques, their procedures, and other metadata. My concern is with MITRE's definition of "tactics" as "short-term, tactical adversary goals during an attack," which is oddly recursive. The key word in the tacti...

Volume 4 offers early white papers that Mr. Bejtlich wrote as a network defender, either for technica...
