ISO 27001

ISO 27001 is an international standard for information security management systems (ISMS). Formally known as ISO/IEC 27001, it is part of the ISO/IEC 27000 family of standards, which are developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

ISO 27001 covers a wide range of security controls across different areas such as risk management, security policy, asset management, human resources security, physical and environmental security, communications and operations management, access control, information systems acquisition, development and maintenance, information security incident management, business continuity management, and compliance.

Organizations that achieve ISO 27001 certification can demonstrate to customers, partners, and other stakeholders that they follow best practices in information security management. Certification involves undergoing an audit performed by an accredited certification body, which assesses the organization's ISMS against the requirements specified in the standard. This certification is often required by regulators or clients, especially in industries where data security is critical.

ISO 27001 is applicable to all types of organizations, regardless of their size, type, or nature, including public and private companies, government entities, and non-profit organizations. The goal is to protect the confidentiality, integrity, and availability of information, which is increasingly critical in our interconnected digital world.

What are the ISO 27001 controls?

ISO 27001 provides a comprehensive framework for securing information assets through a set of controls outlined in Annex A of the standard.
