Great comments from Computer Defence Mon, Mar 5. 2007

I found some great comments to my article on passwords on the Computer Defence blog! There is a neat idea using passwords based on URL's that I think would make very long passwords (40 characters or more) much easier to remember. Check it out!

There were also some references to some of my other posts being old news from 1995. Yeah, it's true. I recently added my about page which describes how I'm using this blog as a way to publish entries from my personal tech notes, that I've created over the last 10 years. I'm trying to start with the ones that are most requested. This approach will certainly lead to tips and how too's that may already be known my many.

Please feel free to take what you need, and skip what you already know. Thanks to Computer Defence blog for giving my a good going over. I'm new to the blogging scene and am humble in my blog foo.

Talking about passprase-based passwords, there is a report published in 2000 on "The memorability and security of
passwords some empirical results" based on the study of 400 first-year students at the University of Cambridge. The report provides some interesting data, e.g.:

"The summary of the number of cracked passwords is as follows (with brute-force attacks treated separately):

- Control group 30 (32%) +3 brute force
- Random password group 8 (8%) +3 brute force
- Passphrase group 6 (6%) +3 brute force
- Comparison sample 33 (33%) +2 brute force"
