His separate guide on CNC is great[1]. He also has a great intro to electronics[2]. His first book is an amazing survey of totally passive attacks[3]. His second book is a comprehensive survey of web application osecurity[4].

Another lesser known book by him is also worth a read: "Silence on the Wire" that takes a look at the full information security stack from the keyboard you type on, to the wires the data transits, to the internet protocols, etc [2] and looking at how each stage exposes/protects data.
And has quite an interesting history in infosec beyond that [3].
