Rediscovery and Security News
First things first: Happy 2012 everyone. So, this blog has been silent for a little while now. More astute readers might argue along the lines of “hey man!

A lot of the data sanitisation literature around advises overwriting partitions with random data (btw, SANS Institute research claims that even a pass with /dev/zero is enough to stop MFM but YPMV).

The trouble with OSSIM
If you fiddle with MSSP, then you will most likely have heard of OSSIM. While the software itself appears quite powerful, it lacks in the MOST critical aspect of all: there is little if any documentation. Most of it is outdated and sources of information include a forum and a blog/tweeter feed. Come on OSSIM… Continue reading The trouble with OSSIM
puts “Hello world!”
This is my new blog. Hopefully stuff will get added here 🙂
