ISO 27001:2022 Annex A Control 5.1

How Does ISO 27001:2022 Annex A 5.1 Work?

Information security policies are designed to protect your company’s sensitive information from theft and unauthorised access.

In accordance with ISO 27001, Annex control A 5.1 guides the purpose and implementation of establishing an information security policy in an organisation.

An overall information security policy is required by Annex A Control 5.1 for organisations to manage their information security. Senior management must approve the guidelines, which must be reviewed regularly if changes occur in the information security environment.

The appropriate approach is to meet regularly, at least once a month, with additional meetings as needed. In addition to sharing policies with internal and external stakeholders, management must approve any changes before they are implemented.

Getting Started and Meeting the Requirements of Annex A 5.1

A detailed operating procedure that describes how the information security policy will be implemented should be based on and supported by an information security policy.

The policy should be approved by top management and communicated to staff and interested parties.

In addition to giving direction to the organisation’s approach to managing information security, the policy can be used to develop more detailed operating procedures.

As required by ISO/IEC 27000 standards, a policy is essential to establishing and maintaining an information security management system (ISMS). A well-defined policy remains critical even if the organisation doesn’t intend to implement ISO 27001 or any other formal certification.

Information security policies should be reviewed regularly to ensure their continued suitability, adequacy and effectiveness.

When changes are made to the business, its risks, technology, legislation, or regulations, or if security weaknesses, events, or incidents indicate policy changes are needed.

What Are the Changes and Differences From ISO 27001:2013?

As part of ISO 27001 revision 2013, this control merges Annex A controls 5.1.1 Policies for Information Security and 5.1.2 Review of Policies for Information Security.

Annex A control 5.1 in ISO 27001:2022 has been updated with a description of its purpose and expanded implementation guidance, as well as an attributes table that allows users to reconcile Annex A controls with industry terminology.

According to Annex A 5.1, information security and topic-specific policies should be defined, approved by management, published, communicated to, and acknowledged by the appropriate personnel.

An organisation’s information security policy should consider the size, type, and sensitivity of information assets, industry standards and applicable government requirements.

According to clause 5.1.2 of ISO 27001:2013, the purpose of Annex A is to ensure that information security policies are regularly evaluated if changes in the information security environment arise.

According to ISO 27001: 2013 and ISO 27001: 2022, top management should develop a security policy that is approved by top management and describes how the organisation will protect its data. Nevertheless, both versions of the policies cover different requirements.

Comparative Analysis of Annex A 5.1 Implementation Guidelines

According to ISO 27001:2013, information security policies should address the following requirements:

• The business strategy.
• Contracts, regulations, and legislation.
• A description of the current and projected threat environment for information security.

Information security policies should include the following statements:

• All activities pertaining to information security should be guided by a definition of information security, objectives and principles.
• Information security management responsibilities are assigned to defined roles in a general and specific manner.
• The process for handling deviations and exceptions.

In contrast, ISO 27001:2022 has more comprehensive requirements.

As part of the information security policy, the following requirements should be taken into consideration:

• Strategy and requirements of the business.
• Legislation, regulations, and contracts.
• Information security risks and threats that exist today and in the future.

Statements concerning the following should be included in the information security policy:

• Information security definition.
• A framework for establishing information security objectives.
• Information security principles should guide all activities.
• A commitment to comply with all applicable information security requirements.
• An ongoing commitment to improving the information security management system.
• Role-based assignment of responsibilities for information security management.
• Exceptions and exemptions are handled in accordance with these procedures.

In addition, ISO 27001:2022 was revised to include topic-specific policies for information security incident management, asset management, networking security, incident management, and secure development as topic-specific policies. For the purpose of creating a more holistic framework, some of the requirements of ISO 27001:2013 were removed or merged.
