There is a new book out for those looking to get a good introduction to infosec in The Basics of Information Security: Understanding the Fundamentals of InfoSec in Theory and Practice by Jason Andress.
Rather than trying to cover everything in a 1,200 book, the authors take broader approach and condense things to about 200 pages.
Perhaps the best introductory text has been Computer Security Basics by Rick Lehtinen and G.T. Gangemi. But that text has not been updated in over 5 years, and it somewhat out of date.
Looks to be a good read.
Full review to follow.
