ISO 27001 is an international standard for information security management systems (ISMS). It provides a systematic approach to managing sensitive company information, ensuring its confidentiality, integrity, and availability. ISO 27001 is designed to be applicable to organisations of all sizes and industries.
Key elements and principles of ISO 27001 include:
Risk Assessment and Management
Organisations are required to identify and assess information security risks and then implement controls to manage or mitigate those risks.
Information Security Policy
Establishing a set of policies and procedures to guide the organisation in managing information security.
Asset Management
Identifying and managing information assets, including their classification and handling.
Physical and Environmental Security
Implementing measures to prevent unauthorised access, damage, and interference to information and information processing facilities.
Access Control
Ensuring that access to information and information processing facilities is restricted to authorised users.
Cryptographic Controls
Using encryption and other cryptographic methods to protect sensitive information.
Business Continuity and Disaster Recovery
Preparing for and responding to disruptions to business activities, ensuring the availability of critical information and services.
Incident Management
Establishing an incident response process to manage and respond to information security incidents.
Compliance
Ensuring that the organisation complies with relevant laws, regulations, and contractual requirements related to information security.
ISO 27001 certification involves a comprehensive audit of an organisation’s information security management system by an accredited certification body. The certification process typically includes an initial assessment, followed by regular surveillance audits to ensure ongoing compliance.
Achieving ISO 27001 certification demonstrates an organisation’s commitment to information security and provides assurance to stakeholders, customers, and partners that appropriate measures are in place to protect sensitive information. As with other ISO standards, ISO 27001 emphasises the importance of continual improvement, ensuring that the organisation adapts to evolving security threats and challenges.
