⚠️ Episode 5 – Insecure Design | OWASP Top 10 Explained

**Good code can’t fix a bad blueprint.**
In this episode, we explore **Insecure Design**—a critical but often overlooked entry in the OWASP Top 10 (A04:2021). Unlike implementation bugs, these vulnerabilities come from flawed decisions at the **design** level.

🔍 **In this episode, you’ll learn:**

* What “Insecure Design” really means
* The difference between design flaws vs. implementation flaws
* Real-world examples of poor architectural decisions
* How insecure workflows, missing threat models, and bad logic put users at risk
* Strategies for building security into the design phase
* Why prevention is better than patching

---

🧱 **Why This Matters:**
Insecure Design is about **the choices you make before you write any code**—things like trust boundaries, permission models, data flow, and default behavior.
Even secure code can’t protect an app that was never designed with security in mind.

Attackers love design flaws because they’re often:

* Harder to detect
* Easier to exploit
* And more damaging when discovered late

---

📉 **Common Examples of Insecure Design:**

* Missing or weak access control schemes
* Unsafe defaults (like passwordless access or exposed debug routes)
* Insecure business logic (e.g. discounts applied after payment)
* No rate limiting or abuse prevention
* Trusting data from the client side
* Failing to build with the principle of least privilege

---

🧠 **What Developers & Architects Should Do:**

* Incorporate **threat modeling** early
* Use secure design patterns
* Consider **misuse cases**, not just use cases
* Follow **secure-by-default** principles
* Document trust boundaries and enforce them
