Introduction
In today’s digital world, safeguarding information is more critical than ever. ISO 27001 is an international standard that outlines the specification for an information security management system (ISMS). It is designed to help organizations make the information assets they hold more secure.
The standard provides a framework for organizations to establish, implement, maintain, and continually improve an ISMS. It adopts a process-based approach for establishing, operating, monitoring, reviewing, maintaining, and improving an ISMS. This marks a significant step forward as it provides a clear structure and guidelines to protect information comprehensively and systematically, ensuring the confidentiality, integrity, and availability of corporate information by applying risk management processes.
