Attacking Full Disk Encryption 2
As usual, security and convenience ride a fulcrum. As things are easier to use, security usually suffers. That applies to full disk encryption too.
What?
I was reviewing a B-sides talk by Tom Kopchak on defeating full-disk encryption. Tom was able to gain administrative access to a Windows laptop with full-disk encryption enabled. We aren’t always safe.
8 Techniques For Getting Help with Linux
How to ask for help for Linux issues.
All of us need a little help now and again. Linux users aren’t any different than MS-Windows or Mac users in that regard. The difference is that to get help for Linux, you need to do a little more research first.
We’ll assume you don’t have a nearby Linux knowledgeable friend that knows everything. You’ll need to ask people you do not know for help. Or, perhaps you are the Linux guru in your circle of friends and your questions are more complex than most.
Below, I’ll suggest a few methods to use to get help and outline the data you should include in your requests to optimize the ability of others to actually be helpful to you.
Make Windows Almost 50% Faster Under VirtualBox 2
I’ve been slightly disappointed with overall VirtualBox performance and decided to see what I could do to make things faster. For me, there are 3 elements to the performance issue. CPU, Disk and Network I/O. At this point, I only have possible solutions for two of the three areas.
My server is running Ubuntu Server x64 10.04 with VirtualBox 3.1.6 OSE directly from the Ubuntu repository. Below, I’ll describe how to improve both disk and network I/O performance. I think these suggestions will apply to other versions and MS-Windows hosts too.
Installation of VirtualBox OSE 3.1.x on Ubuntu 10.04 (Lucid)
Installation of VirtualBox OSE (Open Source Edition) using the Ubuntu repositories should be easy. For me, there were a few issues that I figure other people may run into. I was able to solve them.
Windows WMI Security - a Mystery
I use virtualization … a lot. I started writing an article entitled Converting WinXP from VirtualBox to KVM today, but couldn’t due to issues.
The latest thing I’m trying to accomplish is to migrate to KVM for all the current VM needs that I have. This may not be a good idea since we’re running Xen, VirtualBox and ESXi VM hosts. Today I attempted to convert a WindowsXP Professional install running under VirtualBox 3.x to KVM. I’ve attempted this conversion before, but it failed, badly. This time, I’m using VMware Converter and it failed before it even got started.
