What are the requirements of ISO 27001?

ISO 27001 is an international standard that defines the requirements for establishing, monitoring, and implementing information security management systems. This standard also includes the requirements for the assessment and treatment of the risk. To achieve ISO 27001, an organization must comply with the clauses from 4 to 10 in the standard. Best Practice can help your organization to achieve the ISO 27001 Certification.

Requirements of ISO 27001:

ISO 27001 is required to show customers, suppliers, and stakeholders that you can keep information data safe and secure. To become certified to ISO 27001, companies need to undergo evaluation against the standard and need ongoing surveillance audits to ensure ongoing compliance. ISO 27001 evaluates how well a company can manage its information security risks.

Clause 4 Context of the organisation

In this clause, a certification body will look at the context of an organization’s structure. An auditor can identify the internal and external issues, e.g., people, suppliers, government bodies/agencies, etc., impacting the information security management system. Thus, an organization must determine the boundaries and applicability of the ISMS to establish its scope. It could include the people and the other activities performed at various levels.

Clause 5 Leadership

In this clause, the management needs to establish policies and procedures concerning information security. The main objectives, applicability, and compatibility with the strategic direction must ensure that information security is the organization’s top priority. The management’s leaders involved in the project are responsible that the ISMS comply with the standard’s requirement in ISO 27001.

Clause 6 Planning

In this clause, the planning stage comes after identifying risks and threats in the information management systems. An internal auditor will perform a complete risk assessment before the external certification body enters to implement the standard. The auditor will then plan to apply the strategies to reduce or eliminate the risk—a complete statement of Applicability to control the risk to implement the ISO 27001 standards.
