ISO 27001 Requirements

Compliance with ISO 27001 requires familiarity with the standard, diligent planning, and committed implementation. To facilitate the process, you need to fulfill the necessary ISO 27001 certification requirements.


The ISO 27001 requirements guide discusses the ISMS policies and procedures you must implement to demonstrate compliance with the clauses (4-10) listed in the ISO 27001 compliance framework.

Once you’ve identified the scope of ISO/IEC 27001 security standards for your business and conducted a gap analysis to understand the areas that need to be addressed to align with the ISO 27001 requirements checklist, you then start implementing the requirements listed in the clauses. The ISO 27001 compliance requirements you implement will be tailored to your business and the scope you want to convey to your auditor before an audit.

What are the ISO 27001 requirements?

ISO 27001 requirements are a list of requisites that organizations need to implement and maintain to create a robust ISMS. The requirements include scope, leadership commitment, policies, security controls, internal audits, risk assessment, and risk management.

The requirements of ISO 27001 include implementing an adequate level of resources for the establishment, application, management, and continual improvement of the information security management system (ISMS).

With the list of ISO/IEC 27001 requirements, you’ll have a roadmap to build a comprehensive and effective ISMS to build an effective internal audit program to focus on what matters most: keeping your company information assets safe and secure and complying with the regulatory requirements.

Why do organizations need to follow ISO 27001 requirements?


To become ISO 27001 certified, it is necessary to align your ISMS (Information Security Management Systems) with the requirements of ISO 27001. These requirements aim to help organizations continuously create, maintain and improve their ISMS posture.

Also, one of the essential components of ISO 27001 implementation is conducting a gap analysis. This analysis involves comparing an organization’s current information security practices against the requirements outlined in the standard.

This is why, we have created a free downloadable template for you:

List of ISO 27001 requirements

There are seven ISO 27001 requirements (clauses) listed through clauses 4-10 in the compliance framework your organization would have to become compliant with based on the scope of your ISMS.

Here is the list of ISO/IEC 27001 requirements:

Clause 4: Context of the organization

The scope sets the context you draft for ISO 27001 compliance. The scope will include information on the risks you’ve identified and the measures you implemented to mitigate unauthorized access to sensitive information.

The auditor also uses this scope during the ISO 27001 audit to understand the risks you’ve identified and implemented security measures for within the organization.

Clause 5: Leadership and commitment

Top and senior management of the organization should demonstrate ownership and commitment to compliance by participating in training programs contributing to security goals, and enabling the team with the resources required to get the job done efficiently.

Clause 6: Planning for risk management

ISO 27001 does not mandate a list of things every organization should implement to become compliant. Instead, they require organizations to tailor-make security measures and policies unique to their business to safeguard your ISMS from security incidents. Every business works uniquely; hence, the risks to maintaining the safety, confidentiality, and integrity of sensitive data vary significantly.

Clause 7: Allocation of resources

ISO 27001 requires organizations to allocate resources to meet the ISO 27001 requirements. Unfortunately, most organizations misunderstand this clause and struggle to allocate full-time resources to implement and manage ISO 27001. This clause states that specific team members of your organization can take ownership of implementing security and policy requirements listed in the ISMS. And that the employees tasked with this should be given access to training resources.

Clause 8: Regular assessments and evaluations of operational controls

ISO 27001 requires organizations to continuously monitor their ISMS and evaluate if the performance of the controls and policies implemented are effective. With periodic performance evaluations and security risk assessments, organizations are expected to improve their systems to meet the requirements consistently. In addition, these performance evaluations should be documented and presented as evidence during an audit to demonstrate compliance.

Clause 10: Improvement & correction plan for Nonconformity(s)

Whenever there is a nonconformity in your ISMS, your organization must document that instance with reasons explaining what caused the occurrence of the nonconformity and the corrective measures implemented.


Improvement & correction plan for Nonconformity

The document recorded should contain information on the following:

  • The individual responsible for the nonconformity
  • The nature of the nonconformity
  • Details on concessions (if applicable)
  • Corrective measures implemented
  • Implementation of corrective action plan

How ISO 27001 Annex A controls are related to ISO 27001 requirements?

ISO 27001 requirements list the policies and controls that an organization must implement. However, it does not offer a validating mechanism to check if the deployed controls are functioning correctly.

This is where Annex A comes in. During an audit, an auditor uses Annex A as the benchmark to measure the effectiveness of the policies and 114 controls of the ISO 27001 framework.

To make it easier for you, we have put together the complete ISO 27001 controls list. You can download the list below to effectively align your systems with the ISO requirements.

What is common between ISO 27001 and ISO 9001?

ISO 27001 is an internal security standard that helps businesses deploy information management security systems (ISMS) to protect sensitive information. ISO 9001 allows organizations to continuously improve their existing products and services by implementing Quality Management Systems (QMS). While both are international standards, they differ in various aspects, but they have a few similarities listed below:

Maintains Compliance

Both standards require organizations to monitor their information security systems, ensure proper security measures and processes are in place, and maintain the desired efficiency level to achieve compliance with regulations. 

Internal Audit Process

Both standards will require organizations to run internal audits and review the risk profile to assess the performance and compliance of the security management systems.

Corrective Measures

Both standards require organizations to implement corrective measures to achieve compliance for those areas of their business environment that record nonconformities and enable continuous improvement in fulfilling security objectives.

Leadership commitment

Both standards require businesses to assign owners to execute different duties of the compliance process. Therefore, the same method used to define the requirements and policies of the security aspect can be used to implement the security aspect of ISO 9001.

Risk assessment and awareness

While both standards are predominantly used as security standards, they require you to perform assessments of security risks to identify gaps and implement processes to bypass risks and ease your ISO certification process.

Why do you need to implement ISO 27001 requirements?

To be compliant with ISO 27001, implementing the ISO 27001 requirements is essential. This is usually done after a gap analysis. You get insights into the policies and controls you’ve already implemented and the ones yet to be done.

Is ISO 27001 a legal requirement?

ISO 27001 is not a legal requirement. However, it is a globally accepted set of standards that organizations implement to demonstrate their capabilities of ensuring the security and integrity of sensitive information to their business prospects and end-users.

Are Annex A controls mandatory?

No, it is not mandatory to implement all 114 ISO 27001 controls listed under Annex A. You can select and implement the controls that apply to your organization based on the risk profile.

What are the mandatory requirements of ISO 27001 certification?

The mandatory requirements for organizations to achieve ISO 27001 certification are: 

  • Implementing an Information Security Management System (ISMS)
  • Conducting a risk assessment
  • Develop security policies and procedures
  • Risk management processes for implementing controls   
  • Reviewing the effectiveness of the ISMS
  • Communicate the ISMS to all employees and train them.

Who needs to comply with ISO 27001?

Any business or service provider who handles, processes, or transmits client data should comply with ISO 27001. Though it is not a compulsion, operating without a comprehensive security framework is increasingly getting more challenging.
