I have read the first edition, not the second yet.
There is very little good material written publicly about building secure systems rather than breaking them or fixing components. This book describes a series of systems (not just stand alone IT systems) and describes their security in their social / cultural / physical context.
It's not a patch and firewall compliance guide, it uses the systems word appropriately. There are no big methodologies or techniques, which is appropriate as these just don't exist at the scale this book discusses.
For technical 'breakers' moving into the world of building it's a useful book.
