I preferred The Open Group's O-ESA Open Enterprise Security Architecture (O-Esa): A Framework And Template For Policy-Driven Security (Security (Van Haren Publishing)) https://www.amazon.com/dp/9087536720/

This is a good book, too. Sherwood's book (check out SABSA) - Enterprise Security Architecture: A Business-Driven Approach https://www.amazon.com/dp/157820318X/

For background on basic Enterprise Architecture versus security domain architecture this was one of my first. It's not a fast read by any means but it's served me well for years. An Introduction to Enterprise Architecture: Third Edition https://www.amazon.com/dp/B0792RV5XD/
