Hu Yoshida: Virtualization is about lying

Eric Hibbard, the plain speaking Chair of the SNIA Security Technical Work Group, often says that Virtualization is about lying and security is about understanding the truth. I prefer to say that virtualization simplifies management and improves efficiency by masking the underlying physical complexity.

Eric also makes the point that if you are going to lie, you better be in position to know the truth as well. I whole heartedly agree with him there. That is why it is important to do your storage virtualization where you are also working with the truth and the only place to do that is in the storage control unit, not in the storage network. If you are virtualizing storage in the storage network, creating virtual volumes with mapping tables, while the real volumes, cache slots and track tables reside in the storage array, you have a disconnect and a potential for a security disaster, i.e., the loss or compromise of data..



Well we can say that about everything in life. Our lives on this planet too is a lie. We just happen to inhabit this piece of rock which is part of the 200,000 billion star-systems (or solar systems).

OK, my point is: You CAN lie about virtualization and you CAN blame everything on everything else, BUT you have to understand one thing: Not only you must know and understand the truth, but the fact the person you are lying to, will find out the truth.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Splunk that!

Saw this advert on Slashdot and went on to look for it and found the tour pretty neat to look at. Check out the demo too! So why would I need it? WHY NOT? I'd say. As an organization grows , new services, new data comes by, new logs start accumulating on the servers and it becomes increasingly difficult to look at all those logs, leave alone that you'd have time to read them and who cares about analysis as the time to look for those log files already makes your day, isn't it? Well a solution like this is a cool option to have your sysadmins/operators look at ONE PLACE and thus you don't have your administrators lurking around in your physical servers and *accidentally* messing up things there. Go ahead and give it a shot by downloading it and testing it. I'll give it a shot myself! Ok so I went ahead and installed it. Do this... [root@tarrydev Software]# ./splunk-Server-1.0.1-linux-installer.bin to install and this (if you screw up) [root@tarrydev Software]# /op

Virtualization is hot and sexy!

If this does not convince you to virtualize, believe me, nothing will :-) As you will hear these gorgeous women mention VMware, Akkori, Pano Logic, Microsoft and VKernel. They forgot to mention rackspace ;-) virtualization girl video I'm convinced, aren't you? Check out their site as well!
