🔐 OWASP Top 10 in AWS: A Practical Security Series for Builders

Posted by DevegygiebyOL

Most security breaches don’t happen because attackers are geniuses.
They happen because:

Access control is missing one check
Encryption is configured “later”
Input validation is assumed, not enforced

The OWASP Top 10 documents these exact failures—the most common, most dangerous application security risks seen across the internet.
This series is about understanding them deeply and fixing them practically, specifically in AWS‑based architectures.

🎯 What This Series Is (and Isn’t)
✅ What You’ll Get

Clear explanations of each OWASP Top 10 category
Realistic AWS examples (API Gateway, ALB, ECS, Lambda, WAF)
Practical mitigation strategies you can apply immediately
Security reasoning that developers, DevOps, and architects can align on

❌ What You Won’t Get

Vendor fluff
Overly academic theory
Fear‑driven security talk
“Enable this checkbox and you’re done” advice

This is about how vulnerabilities actually happen in real systems—and how to stop them.

🧭 Why the OWASP Top 10 Still Matters
The OWASP Top 10 is more than a list. It’s the common language of application security.
It matters because it:

🛠 Aligns Engineering & Security
Tools like AWS WAF, F5, Burp Suite, and SAST/DAST scanners reference OWASP risks directly.

📜 Defines Compliance Baselines
Standards like SOC 2, PCI DSS, HIPAA, and ISO 27001 map directly to OWASP categories.

🚨 Focuses on Real‑World Breaches
Addressing the OWASP Top 10 mitigates the majority of web application attacks seen in production.

If you build or operate applications, you’re already dealing with OWASP—whether you realize it or not.

🗺️ The 10‑Day Roadmap
Each post covers one OWASP category per day, with hands‑on cloud context.

✅ Day 1: Broken Access Control (A01:2021)
🔐 Day 2: Cryptographic Failures
💉 Day 3: Injection
🔄 Day 4: Insecure Design
⚙️ Day 5: Security Misconfiguration
🧩 Day 6: Vulnerable & Outdated Components
🔑 Day 7: Identification & Authentication Failures
📊 Day 8: Software & Data Integrity Failures
📝 Day 9: Security Logging & Monitoring Failures
🌐 Day 10: Server‑Side Request Forgery (SSRF)

Each post stands alone—but together they form a complete security mindset.

☁️ AWS‑First, Vendor‑Aware
Examples and mitigations will focus on:

AWS WAF & Shield
API Gateway
Application Load Balancers
ECS, EKS, and Lambda
IAM, CloudWatch, and CloudTrail

Where useful, I’ll also reference advanced WAFs (like F5) to show how defense‑in‑depth actually works in real enterprises.

👥 Who This Series Is For

Backend & frontend developers
Cloud & DevOps engineers
Architects responsible for secure design
Security engineers working with product teams
Anyone tired of security advice that doesn’t map to real systems

If you’ve ever said:

“We’ll fix security later…”

This series is for you.
