Computer Security: Art and Science, by Matt Bishop; Addison Wesley Professional, 2002.
Bishop is a well-known security expert. His Computer Security is a good textbook for university courses but has more limited value for business security professionals. The prose has that dry, textbook feel, with ideas presented as theorems, and much mathematical notation.
On the other hand, if you want a grounding in the underpinning theory of IT security, Computer Security can provide that.
