OS security is something that really aught to be discussed separately from OS texts. I mean, not all OSes are multiprogramming or need security. Earlier version of his Operating Systems book taught MS DOS, along with others, for example. Security exposition is something best left to a separate text, and Matt Bishop's fat book does a good job (not the thin watered down one.)
