ISO 27001 Annex A 8.28 Secure Coding Explained

Before diving into the implementation process, let's start with some of the fundamentals.

In this section we will start with defining ISO 27001 Annex A 8.28 Secure Coding.

We will then move onto understanding its purpose in the context of your ISMS.

Finally, we will discuss the importance of ISO 27001 Annex A 8.28 Secur Coding in your organisation.

Let's get started.

‍

Defining ISO 27001 Annex A 8.28 Secure Coding

ISO 27001 Annex A 8.28 is a new Annex A Control that came in ISO 27001:2022.

It is a preventive control that focuses on establishing an organisation-wide approach to secure coding.

Heard the term "security by design and default"?

ISO 27001 Annex A 8.28 plays a key role in that journey.

It requires you to developing a systematic approach to governing secure coding. It looks at this through a different perspectives:

• How you plan before you code (i.e. planning, threat analysis, risk assessments)
• Considerations around embedding security whilst you code
• How you review and maintain your code

It also outlines requirements for extending your processes and governance to cover software components from third parties and open source software.

‍

Understanding the Purpose of ISO 27001 Annex A 8.28 Secure Coding

Now that we've defined what ISO 27001 Annex A 8.28 is about, let's talk about its purpose.

The goal of ISO 27001 Annex A 8.28 is:

"To ensure software is written securely thereby reducing the number of potential information security vulnerabilities in the software."

It is a proactive approach that aims to identify and address security weaknesses during the development phase, rather than dealing with them after the software has been deployed.

You'll often hear me refer to applications being a gateway to your data.

For example:

• HR systems are the gateway to employee personal data.
• CRM systems are the gateway to customer data.
• Patient management systems are...you guessed it...the gateway to patient data.

Protecting these applications requires a holistic approach to identifying and treating risks.

These controls will cover various areas, including:

• Defining your Application Security Requirements
• Establishing a Secure Software Development Lifecycle
• Secure configuration management
• Ongoing maintenance
• Logging and monitoring
• and more...

Combined, these types of controls ensure that your applications are secure and by extension, your data.

‍
