What standard specifies requirements for an information security management system?

The standard that specifies requirements for an information security management system is ISO/IEC 27001. This standard is widely recognized globally and outlines the criteria for establishing, implementing, maintaining, and continually improving an information security management system (ISMS). ISO/IEC 27001 provides a systematic approach to managing sensitive company information, ensuring that it remains secure. It encompasses people, processes, and technology, allowing organizations to effectively manage their information security risks.

ISO/IEC 27001 includes a set of requirements that organizations must meet to be certified, which ensures that their security practices align with international best practices. By adhering to this standard, organizations can not only protect their data but also establish trust with stakeholders and customers regarding their commitment to information security.

Other standards mentioned, while they address different aspects of information security, do not specifically establish requirements for an overall information security management system. For instance, ISO/IEC 27050-1:2016 deals with the handling of electronic evidence, and ISO/IEC 27043:2015 focuses on incident investigation. NIST Special Publication 800-122 pertains specifically to the protection of personally identifiable information (PII) rather than outlining a comprehensive framework for managing information security as a whole.
