ISO 27001, formally known as ISO/IEC 27001:2013, is an internationally recognized standard that sets forth the requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS). This standard provides a systematic approach to managing sensitive information within an organization to ensure its confidentiality, integrity, and availability. ISO 27001 covers a wide range of aspects related to information security, and in this article, we will delve into its key components and coverage.
