Network Diagrams by Industry · Book 6
Draw Secure Bank and Credit Union Network Diagrams
From Teller Line to FFIEC Exam
Balance the diagram like you balance the drawer.
Network diagrams that survive the examiner's first-day letter, the IT audit and the core conversion.
This book is for you if…
- You're the IT officer or network administrator at a community bank or credit union with 2 to 40 branches, usually on a team of one to five
- You're the information security officer who owns the GLBA program and answers the examiner, network person or not
- You're the MSP, MSSP or IT auditor who gets handed the exam request list
Same shape as every book in the series
Each chapter opens with a short scene where a bad diagram goes wrong, then gives a handful of rules, a real screenshot from the free NetDiagrams tool, a "No NetBox yet?" note, and a Monday-morning checklist you can finish in an hour.
Read Chapter 3 free, no sign-up: Bank Network Segmentation: Teller, Core, Wire and Card Zones.

FAQ
Questions
Do I need NetBox?
No. Every rule works by hand with draw.io and a spreadsheet, and every tool section ends with a short "No NetBox yet?" note. Appendix F walks you through getting your data into NetBox when you're ready.
What format is it?
A 376-page 6x9 PDF and an EPUB for e-readers and phones. Both are DRM-free; each copy carries a line saying it's licensed to you.
How is it delivered?
Right after checkout you get a download link by email. If the link ever fails, write to hello (at) netdiagrams.com and we'll send the files directly.
Is the NetDiagrams tool free?
Yes. The tool is open source under the Apache-2.0 license, and the book's screenshots are its real output. You don't need to buy the book to use the tool.
Is there a Kindle edition?
Yes, at $29.99. It has the same text, but the drawings are easier to read in the 6x9 PDF, which only comes with a copy bought here.
What's in the Complete Library?
All 10 books (manufacturing, education, warehousing and logistics, retail, offices, banks and credit unions, local government, hotels and hospitality, corporate hq and multi-site, car dealerships), each as PDF and EPUB, from one download link. Bought separately they'd be $390. It covers the books out today; a future book is sold separately.
Can I pick just two or three books?
Yes. Any 2 books are $69 and any 3 are $89. Choose them on the series page and they come on one download link.
Can my team share one copy?
The Team license covers one book for up to 10 people at one company, for $249. The Team Library covers all 10 books for the same team, for $699. For more people, email us.
Who handles payment?
Paddle is our merchant of record. They handle checkout, sales tax and VAT, and invoices for your accounts team.
