Sources of network security templates or designs

While every network designer/architect with an emphasis on security has his or her favorite design templates, I'm wondering what public sources do people start with? Cisco SAFE and other published designs IBM Redbooks DOD Security Technical Implementation Guides (STIGs) NIST Special Publications O'Reilly series (specific books?) Of course, every designer customizes things based on the project and preferences. So I'm not asking for what's best, or even what's wrong with particular sources. Just where do you start?
