Can anyone recommend any good literature about Honeypots?

I'm interested in learning more about Honeypots and Honeynets. I've used low interaction Honeypots like Honeyd in the past, but now I want to take it to the next level.

Can anyone recommend any good books or papers about Honeypots/Honeynets?

There are a few books on the subject (although I've never bothered with them), however I can recommend you some readily updated websites:

The always interesting honeyblog

The European Network of Affined Honeypots has many recent papers and presentations

The Honeynet Project has some good papers

Distributed honeypot management software and a video discussion of the current state of the threat

A directory of honeypot server related sites

Shadowserver has some good general stats

Finally there are some old (circa 2000) papers cited in this article

I just finished reading the book Beautiful Security, and it has a nice chapter on 'honey clients'. Instead of focusing on server side exploits, they look at how malware installs itself onto a client. The book has some good suggestions on using VMWare, and detecting system changes.
