At the recent Sydney Joomla meeting there was a bit of discussion on security. Here is a URL to an introduction to it from Smashing Magazine.

BTW thanks Peter from PWweb for putting me on to this excellent resourse - buy the book - it's a great read.

Cheers

I've enjoyed reading the Smashing book over the last month.

My copy is starting to fall apart! I need some nice glue to hold the thing back together.

My favourite part is about the conversions of web traffic.
