Does ISO 27001 Require Pen Testing?

ISO 27001 certification allows your company to showcase compliance with internationally recognised standards of information security. Let’s see if pen testing is one of the requirements.

The ISO 27001 standard offers a comprehensive framework for establishing an effective Information Security Management System (ISMS). It outlines the necessary policies and procedures to safeguard your organisation, encompassing all essential risk controls – legal, physical, and technical – for a robust IT security infrastructure.

Achieving certification demonstrates your company’s commitment to implementing adequate security measures to protect information and data from unauthorised access, corruption, loss, or theft.

How Long does Your ISO 27001 Certification Lasts?

The initial certificate is valid for one year. After a successful recertification audit, you will receive a certificate valid for three years. To maintain your certification during this period, you must successfully complete one mandatory audit each year.

What are ISO 27001 requirements?

ISO 27001 requirements are divided into four main groups:

  1. Management Responsibility: This set focuses on the involvement of senior leaders in your information management system.
  2. Resource Management: This set addresses how you organise your staff, business infrastructure, facilities, and equipment.
  3. Information Security: This set requires the development of processes to protect both physical and digital information assets.
  4. Measurement, Analysis, and Improvement: This set involves establishing processes to assess the effectiveness of your management system and identify areas for improvement.

What Industries Need ISO 27001 Certification?

ISO 27001 helps organisations keep their sensitive information safe. Industries that are most likely to need an ISO 27001 based on the sensitive data they manage include:

  • Information technology
  • Healthcare
  • Finance
  • Consulting
  • Telecoms

Is a Pen Test required to Meet ISO 27001 Standards?

The short answer is no but let’s have a look why your organisation still might need to do a penetration test.

Penetration testing is not explicitly mentioned in the requirements of ISO 27001:2022. However, the supporting standard ISO 27002:2022 includes several references to it.

Since ISO 27002 is not part of the certification scheme, penetration testing is not a mandatory requirement. Therefore, you may choose an alternative method to address this aspect of information security.

Alternatives to Pen Testing

While penetration testing offers many benefits to your organisation, it can be quite costly depending on the project’s scope.

There are various approaches to testing, such as black-box, white-box, or grey-box testing, which generally refer to the test’s origin within the network and the amount of background knowledge the tester has.

Some alternative methods to test your technical network controls include web-based port scans, vulnerability assessments, or using the audit tools built into your security appliances.

  • Web-based port scans are tools that check for open ports on your network devices. These scans help identify which ports are open and potentially vulnerable to attacks. They can be used to verify firewall rules and ensure that only necessary ports are open.
  • Vulnerability assessments involve using automated tools to identify, classify, and report security vulnerabilities in your IT infrastructure. These assessments can cover various aspects, including network, host, application, and database vulnerabilities. They help prioritise remediation efforts by providing detailed insights into the severity and potential impact of each vulnerability. Regular vulnerability assessments are crucial for maintaining a secure environment and ensuring compliance with security standards.
  • Many security appliances, such as firewalls and intrusion detection systems, come with built-in audit tools. These tools can perform various security checks, including configuration reviews, log analysis, and compliance audits. They help ensure that your security appliances are correctly configured and functioning as intended. Regular audits using these tools can help identify misconfigurations and potential security gaps.

By recording and analysing the results of these scans and taking any necessary actions, you can achieve a basic level of security.

 

Reasons to Carry out Pen Testing

Conducting a penetration test is not only good practice and an effective way to manage network risks, but it may also be required for other reasons.

Cyber Essentials Plus, a scheme designed by the UK Government and a requirement for many public sector contracts, explicitly mandates the conduct of a penetration test. Additionally, clients may require regular penetration tests for software products, especially when these products host their data.
