Understanding ISO 27001:2022 and the ISMS Framework

ISO/IEC 27001:2022 Information Security Management System standard defines how organizations build an Information Security Management System (ISMS).

An ISMS framework is a systematic approach to:

• Protect confidentiality, integrity, and availability of information

• Manage cybersecurity risks

• Establish security policies and controls

• Continuously improve information security practices

ISO 27001:2022 follows the Plan–Do–Check–Act (PDCA) cycle, ensuring continuous improvement. Join ISO 27001 Lead Auditor certification course
