Let's get started.

Defining ISO 27001 Annex A 8.26 Application Security Requirements

ISO 27001 Annex A 8.26 focuses on application security requirements in your business.

It requires you to identify, specify and approve information security requirements for applications, such as:

  • Web applications
  • Mobile applications
  • Desktop applications

Regardless of whether we are developing them or buying them.

ISO 27001 Annex A 8.26 is what's called a preventive control. A control intended to prevent cyber risk by protecting applications, systems and networks.

Heard the term "security by design and default"?

ISO 27001 Annex A 8.26 plays a key role in that journey.

Understanding the Purpose of ISO 27001 Annex A 8.26 Application Security Requirements

Now that we've defined what ISO 27001 Annex A 5.15 is about, let's talk about its purpose.

The goal of ISO 27001 Annex A 8.26 is:

To ensure all information security requirements are identified and addressed when developing or acquiring applications.

Your goal is to understand what could go wrong.

Read the standards. Talk to your team. Make sure everyone gets what’s at stake.

Imagine your business like a fortress. The walls (your applications) need to be strong.

Otherwise, intruders can slip in. Get clear on the requirements. Know what needs to be done to keep your fortress safe.

Step #2 - Identify your assets

Now, look at what you’ve got.

Which applications are most important to your business? List them all.

Think about customer data, financial systems, and communication tools.

Identify every piece of software that keeps your business running.

Picture your assets as treasures in a vault.

You need to know what’s there to protect them properly.

Once you’ve identified your assets, you can prioritise which ones need the most protection.

Step #3 - Perform a risk assessment

Next, it’s time to look for danger.

What risks do your applications face?

Hackers, malware, insider threats?

Conduct a risk assessment.

Analyse where your applications are vulnerable.

Look at past incidents and current threats.

Think of it like a doctor diagnosing a patient.

You need to know what’s wrong before you can fix it. Identify the weak spots and understand the potential impact of an attack.

This step is crucial for making informed decisions.

Step #4 - Develop policies and procedures

With risks identified, set the rules.

Develop policies and procedures to protect your applications.

These are your game plans for security.

Create clear, simple guidelines. Cover everything from password policies to incident response plans.

Think of policies as the playbook for your team.

Everyone needs to know their role and what to do in every situation.

Make sure these policies are easy to understand and follow.

Don't forget your control of documentation information either.

Step #5 - Implement controls

Now, put those plans into action.

Implement security controls to safeguard your applications.

This includes firewalls, encryption, and access controls.

Think of these controls as locks on your vault.

They keep intruders out and protect your treasures.

Ensure each control is properly set up and functioning.

Test them regularly. Your goal is to create multiple layers of security, making it hard for any threat to get through.

Step #6 - Training and awareness

Your team needs to be in the know.

Conduct training sessions to make everyone aware of the policies and procedures.

Teach them about the importance of application security.

Show them what threats look like and how to respond.

Picture this step like a training camp.

Your team needs to be sharp, alert, and ready to tackle any threat.

The more they know, the better they can protect your applications.

Step #7 - Evaluate effectiveness

Check how well your security measures are working.

Evaluate the effectiveness of your controls and policies.

Conduct audits and reviews.

Look for gaps and areas that need improvement.

Think of it like a performance review.

You need to see what’s working and what’s not.

This helps you adjust and enhance your security strategies.

Regular evaluation ensures you stay ahead of potential threats.

Step #8 - Continual improvement

Security is never a one-and-done task. Keep improving.

Learn from incidents and adapt to new threats.

Update your policies, procedures, and controls regularly.

Stay informed about the latest security trends and technologies.
