If you’re looking to get ISO 27001 certified or recertified, it’s important to ensure that your information security controls are effective and aligned with the latest standards. The ISO 27001:2022 update introduced significant changes, including the addition of 11 new controls in Annex A. Understanding these updates and how to implement them will put you in a better position to pass an ISO 27001 audit and achieve certification.
In this guide, we’ll break down the essential elements of ISO 27001:2022 Annex A controls so you can confidently prepare for your audit, improve your Information Security Management System (ISMS), and safeguard your organization against risks.
What Are ISO 27001 Annex A Controls?
ISO 27001 is an international standard for managing information security. Annex A of the standard lists 93 controls grouped into four categories: Organizational, People, Physical, and Technological controls. These controls are the backbone of your ISMS and help you reduce risks related to your business’s information security.
ISO 27001:2022 also aligns with the ISO 27002 standard, which offers more in-depth guidance on how each control works and how to implement them.
What Are the Four Themes of ISO 27001 Controls?
1. Organizational Controls
These cover how your organization approaches security. From having clear security policies to managing third-party risks, these 37 controls help you create a solid security foundation.
Example controls:
- Information security policies
- Supplier relationships
- Access control
2. People Controls
This section focuses on how your employees interact with sensitive data. It includes 8 controls related to human resources security, including background checks and security training for staff.
3. Physical Controls
These 14 controls relate to securing physical assets such as office spaces and data centers. Key areas include clear desk policies, physical entry controls, and protection against natural disasters.
4. Technological Controls
Finally, Technological controls are all about securing IT systems and infrastructure. This section contains 34 controls that focus on areas like encryption, network security, and malware protection.
New Controls in ISO 27001:2022
The 2022 update introduced 11 new controls that address emerging security challenges like cloud services and secure coding. Some of the new controls include:
- A.5.7: Threat intelligence
- A.5.23: Information security for use of cloud services
- A.8.28: Secure coding
These additions reflect the growing importance of digital resilience in today’s business environment.
How to Implement ISO 27001 Annex A Controls
To get certified, you need to implement controls that are relevant to your organization. This depends on the specific risks you face, which you should identify through an ISO 27001 risk assessment. Not every control will apply, but if you decide to exclude one, you need to explain why in your Statement of Applicability (SoA).
Tips for Implementing Controls:
- Customize controls to fit your company’s needs. The standard is flexible so businesses can meet compliance in their own way.
- Document everything: Make sure your policies, procedures, and audits are thoroughly documented. This is key for your ISO 27001 auditor.
- Involve multiple departments: ISO 27001 is not just an IT responsibility. Your leadership, HR, and legal teams should also be involved in implementing the necessary controls.
ISO 27001 Audit and Certification: What to Expect
To achieve certification, you’ll undergo an ISO 27001 audit, where a certified auditor will assess your ISMS. The audit typically consists of two stages:
- Stage 1 Audit: This is a preliminary review where the auditor checks your documentation.
- Stage 2 Audit: In this phase, the auditor will take a deep dive into how well your ISMS is implemented and if your controls are effective.

Preparing for the Audit
- Review your documentation: Ensure all your security policies, procedures, and the Statement of Applicability are up to date.
Conduct an internal audit: Before the official audit, run an internal audit to identify any gaps in your ISMS.
FAQs About ISO 27001 Auditors and Audits
What does an ISO 27001 auditor do?
An ISO 27001 auditor assesses your organization’s compliance with the standard. They check your ISMS, documentation, and the effectiveness of your Annex A controls to determine if you meet certification requirements.
How long does an ISO 27001 audit take?
The audit process can vary depending on the size and complexity of your business, but typically the full process, including both stages, can take a few weeks.
What happens if we fail the audit?
If you fail the audit, your auditor will provide a report highlighting areas of noncompliance. You’ll have time to address these issues and schedule a follow-up audit.
