As required college overview reading, I guess this book would be OK. Its ivory tower is showing. But the crypto chapter (chapter 8) is pretty bad.
On P350 and P389, they refer to 3DES as a 128-bit cipher. But on P366 they change their minds and write "3DES uses three 64-bit keys for an overall key length of 192 bits". Both were wrong. DES only uses 56 of 64 bits for encrypting/decrypting, so 3DES is 168 bit -- not that it's even close to a 168-bit strength against a brute force attack.
They then say the Vernam Cipher is "also known as the one-time pad". Except that the Vernam cipher's keying material repeats when used up (that's why a one-time pad is not called a two or three time pad).
They also discuss old standards that went no where that no one uses, as if they are legitimate competing alternatives (examples, SESAME and S-HTTP). And their crypto chapter discusses S-HTTP, but doesn't even once mention TLS.
These gripes all pertain to the 4th edition (2011).
