Secure Architecture & Design

A comprehensive guide to building security into your systems from the ground up through threat modeling, secure design patterns, and defense-in-depth strategies.

What You'll Learn

  • Threat modeling methodologies (STRIDE, PASTA, DREAD)
  • Architecture risk analysis techniques
  • Security design patterns and anti-patterns
  • Defense-in-depth strategies
  • Zero Trust Architecture principles
  • Cloud-native security patterns
  • Security frameworks (NIST CSF, ISO 27001, CIS Controls)
  • Production-ready reference architectures with IaC

Prerequisites

  • • Basic understanding of networking (TCP/IP, DNS, HTTP/S)
  • • Familiarity with at least one cloud provider (AWS, Azure, or GCP)
  • • Understanding of web application architecture (client-server, APIs)
  • • Recommended: Complete the Web Pentest or Network Security guide first

How to Use This Guide

Architects

Start with sections 01-06 for foundational principles, then use 11-12 as reference for framework compliance and production architectures.

Pentesters

Focus on sections 01-02 (threat modeling/risk analysis), 06 (Zero Trust), and 10 (case studies) to understand what defenders build.

DevSecOps

Sections 07-09 (cloud, APIs, SDLC) are most relevant. Section 12 has IaC examples you can adapt directly.

Quick Reference

Core Principles

  • • Start with threat modeling before writing code
  • • Apply defense in depth — no single control is enough
  • • Use Zero Trust — never trust, always verify
  • • Fail safe — errors should deny, not allow

Key Standards

  • NIST CSF 2.0 — Core risk management framework
  • CIS Controls v8.1 — Prioritized security actions
  • • OWASP ASVS — Application security checklist
  • • NIST SP 800-207 — Zero Trust Architecture
