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.

Clause 7 Support

In this clause, an organization will need to provide all the necessary support required in the external auditor’s certification process. They will require to show documented information on the size and type of activities, processes, products, and services. An auditor will go to all the organization sections and ask for valid proofs of what they are using as a controlling measure to protect their information systems.

Clause 8 Operation

In this Clause, an organization will need to review their internal operating systems. A documented information is required to have confidence the process is carried out as planned in securing the information systems. An auditor will check on the controls planned changes and review the consequences of unintended changes taking action to mitigate any adverse effects, as necessary.

Clause 9 Performance Evaluation

In this clause, an organization seeking certification will require implementing and controlling the risks to protect information security. They require to conduct an internal audit to find the critical factors affecting their information security management systems. To address such criteria, an organization will need to implement certain policies and procedures as advised by the auditor.

Clause 10 Improvement

In this clause, where a nonconformity occurs, an organization must take the necessary steps to correct and deal with the consequences. They need to review and maintain the management direction to secure the information systems. The organization’s response to a need for corrective action is documented in some form of corrective action procedure. This procedure includes the requirement for root cause analysis to ensure that the non-conformance does not occur again.
