ISMS is an abbreviation for Information Security Management System, which is a management system for managing the information security of organizations. With an effective ISMS, organizations can ensure business continuity by proactively mitigating the risk of cyber-attacks and limiting the impact of potential data breaches. Implementing an appropriate level of information security requires a comprehensive understanding of the organization's departments and workflows. ISO 27001 can be used as a starting point for information security work. Although the standard does not directly specify specific security measures, it describes best practices for managing security both internally and externally through its 114 Annex A control objectives. The goal is to protect three important aspects of information:
Confidentiality - to ensure that information is not accessible or disclosed to unauthorized persons, devices, or processes.
Integrity - to ensure that information is complete and accurate and protected against corruption.
Availability - to ensure that information is accessible and usable by authorized users.
