Some time ago Yubico were kind enough to send me an evaluation copy of their Yubikey device. I’ve finally got around to reviewing it and making deployment plans for buying some more. Above is a picture of my Yubikey on the keyboard of my Thinkpad T61 for scale. The newer keys apparently have a [...]
The Security Token Wikipedia page doesn’t seem to clearly describe the types of token.
Categories of Security Token
It seems to me that the following categories encompass all security tokens:
Biometric tokens – which seems rather pointless to me. Having a device I control verify my biometric data doesn’t seem to provide a benefit. The [...]
Bruce Schneier’s blog post about the Mariposa Botnet has an interesting discussion in the comments about how to make a secure system . Note that the threat is considered to be remote attackers, that means viruses and trojan horses – which includes infected files run from USB devices (IE you aren’t safe just [...]
The Opera-Mini Dispute
I have just read an interesting article about the Opera browser . The article is very critical of Opera-Mini on the iPhone for many reasons – most of which don’t interest me greatly. There are lots of technical trade-offs that you can make when designing an application for a constrained environment (EG [...]

I have just filed Debian bug report #556644 against the version of openssh-server in Debian/Unstable (Squeeze). It has a patch that moves the code to set the SE Linux context for the child process before calling chroot. Without this a chroot environment on a SE Linux system can only work correctly if /proc and /selinux [...]
Update: Thanks to Sven Joachim and Andrew Pollock for informing me about /etc/init.d/mountoverflowtmp which exists to mount a tmpfs named overflow if /tmp is full at boot time. It appears that the system was not compromised. But regular reinstalls are always a good thing.
On the 24th of August this year I noticed the following [...]
Jetstar has announced some new changes to the way they manage their IT infrastructure . Some parts of it are obvious things that people have been doing (or wanting to do) for a long time – such as using thin clients with no moving parts (not even cooling fans).
But the really interesting part is [...]
The CK12 project is developing free (CC by SA) textbooks for the K-12 market (with a current focus on the early years of high school) . Their primary aim seems to be flex-books – text books that can be localised and modified to better suit the needs of the students. But of course there are [...]
