ISO 27001:2022 - A8.28 – Secure Coding

*💻 ISO27001 A8.28 – WHY ONE LINE OF BAD CODE CAN DESTROY TRUST, REPUTATIONS… AND LIVES*

Every application you use exists because someone wrote code.
And every vulnerability, error, or system failure usually starts in that same place.

That’s why ISO27001 includes *Annex A Control A8.28 – Secure Coding* — a control that requires organisations to assume one simple truth:

*Your code is always under attack.*

In this video, we break down **ISO27001:2022 A8.28**, explaining what secure coding really means, why it matters, and how poor coding practices can lead to devastating outcomes — from financial loss and system failure to real-world injustice, as seen in the Post Office Horizon scandal.

If your organisation develops software, maintains systems, or relies on bespoke applications, this is essential viewing.

💡 *What You’ll Learn*

✔️ What ISO27001 A8.28 actually requires
✔️ Why ISO27002 says application code should assume constant attack
✔️ How insecure code leads to data breaches and system failure
✔️ The link between secure coding and system integrity
✔️ Why secure coding goes beyond “writing good code”
✔️ Real-world consequences of poor coding practices
✔️ What auditors expect to see for this control
✔️ How secure coding fits into your Secure Development Lifecycle (A8.25)
✔️ How to decide whether this control is in scope or out of scope

🚨 *Why This Control Matters*

Without secure coding practices, organisations expose themselves to:

⚠️ exploitable vulnerabilities
⚠️ incorrect system outputs
⚠️ data integrity failures
⚠️ performance issues and outages
⚠️ financial and reputational damage
⚠️ regulatory and legal exposure
⚠️ systems that simply cannot be trusted

The Horizon scandal shows us something critical:

If the code is wrong, the system is wrong, and people suffer.

And most secure coding failures aren’t malicious - They’re **avoidable**.

🛡️ *What ISO27001 Auditors Look For*

Auditors typically expect evidence such as:

• Segregation of duties (A5.4)
• Threat modelling activities (A5.7)
• Engagement with coding special interest groups (A5.6)
• Classification and handling of source code (A5.12)
• Controlled access to code repositories (A5.15)
• A documented Secure Development Lifecycle (A8.25)
• Secure coding tools and compilers (A8.18)
• Awareness and training for developers (A6.3)
• Risk register entries
• Audit results
• Incident logs

This video explains why auditors care — and how to prepare properly.

🛠️ *What You Need to Do*

You’ll learn how to:

🔧 Understand what development actually happens in your business
🔧 Identify who writes, reviews, and deploys code
🔧 Map coding languages and platforms in use
🔧 Separate development, test, and live environments
🔧 Apply language-specific secure coding practices
🔧 Use trusted guidance (e.g. OWASP, language communities)
🔧 Audit secure coding practices over time

If you already implemented A8.25, this control deepens that work — bringing security right down to the **code itself**.
