What Is ISO 27001?
ISO 27001 is an international standard for information security. It was first published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) in 2005, and later revised in 2013. The standard provides a framework for an Information Security Management System (ISMS). That enables organizations to secure their information assets.
ISO 27001 is based on a risk management approach and is technology-neutral. It provides specifications for a comprehensive set of controls, based on best practices in information security. These controls, outlined in Annex A of the standard, are designed to address specific objectives related to the security of information in a company.
The standard requires the involvement of top management. And that is crucial for ensuring that the information security strategy aligns with the organization’s broader goals and objectives.
What Is The ISO 27001 Standard?
The standard consists of 10 main sections (clauses) and an Annex A with 14 security control categories. Here’s an outline of the main sections:
1. Scope: It outlines the general scope of the standard, referring to the establishment, implementation, operation, monitoring, review, maintenance, and improvement of the documented ISMS.
2. Normative References: This section lists the reference standards used to compile ISO 27001. The only standard listed here is ISO 27000, which provides fundamental terms and definitions.
3. Terms and Definitions: These refer to the terminologies used in the standard.
4. Context of the Organization: This section requires the organization to understand its context and needs and define the scope of the ISMS.
5. Leadership: It highlights the role of top management in the establishment of the ISMS, demonstrating leadership and commitment, and establishing a security policy.
6. Planning: This section discusses the actions needed to address risks and opportunities, ISMS objectives, and planning changes.
7. Support: It looks at the resources needed for the ISMS, competence, awareness, communication, and documented information.
8. Operation: It requires the organization to plan, implement, and control processes.
9. Performance Evaluation: It discusses monitoring, measurement, analysis, and evaluation, internal audits, and management reviews.
10. Improvement: It looks at nonconformity and corrective actions and continual improvement.
Annex A – Reference Control Objectives and Controls: Annex A consists of 14 categories of control objectives and controls, totaling 114 controls that might be applied, based on the risk assessment, to treat identified risks. The categories range from information security policies to supplier relationships and information security incident management.
Overall, ISO 27001 takes a comprehensive approach to information security, involving all aspects of an organization.
What Is The Role Of ISMS In ISO 27001?
An Information Security Management System (ISMS) plays a central role in the application of ISO 27001. It is a systematic approach to managing sensitive company information, ensuring it remains secure. An ISMS includes a suite of activities involving the management of information security risks.
