What to read after Information Technology Security?

Recognizing the increase in value of the information portfolio, this book describes the ways in which IT security has changed from a product focus to a business management process. Discussed is how IT security is not just about controlling internal access to data and systems but managing a portfolio of services including wireless networks, cyberterrorism protection, and business continuity planning in case of disaster. An argument is made for this new perspective, and the resulting changes in the role of IT executives, from protecting against external threats to building trusted security infrastructures linked to business processes driving financial returns, are evaluated.
