What is the primary function of an Information Security Management System (ISMS)?

The primary function of an Information Security Management System (ISMS) is to systematically manage sensitive company information. An ISMS provides a structured framework for ensuring that information security practices are implemented and maintained effectively within an organization. This includes establishing policies, procedures, and controls to protect sensitive data from threats and vulnerabilities.

Implementing an ISMS involves risk assessment and management, which is crucial for identifying potential security risks to information assets and determining how to mitigate them. This systematic approach not only helps in safeguarding the integrity, confidentiality, and availability of information but also ensures that compliance with relevant legal and regulatory requirements is maintained.

By focusing on the management of sensitive information, an ISMS enables organizations to respond to security incidents effectively and continually improve their security posture. This comprehensive strategy is essential for organizations looking to protect their data and maintain trust with stakeholders, making it the correct answer in this context.
