How to design a secure network?

Network Security Design Resources

• I am looking for respected resources that state guidelines on how to design my network from scratch in a secure way, including different positioning scenarios for different network/security appliances like "when to create Vlans", "traffic directions", etc. As per my knowledge, security should be built in and not to be an afterthought. Thus I need to build/design it according to best security practices from a design/architecture perspective. Thanks in advance

  https://www.google.de/search?q=nist+guide+computer+security has some nice resources, as well as http://www.sans.org/reading_room/. and there a some pubications from https://www.bsi.bund.de/EN/Publications/BSIStandards/standards.html, but i dont know if they translatet thje actual versions. finally, there might be a national standard for building and maintaining secure it-infrastructure; ask your local dealer. security should be built in yeah, but security is not a state, but a process and depends on a lot of experience. there is no "read this and the you know it" - thingie, but some guidelines help.
