Definition
ISO 27001 is an international standard that specifies requirements for establishing, implementing, maintaining, and continually improving an information security management system ISMS. It provides a systematic approach to managing sensitive company information so that it remains secure. Organizations use ISO 27001 to protect their information assets through risk assessment and treatment. For example, a financial institution might implement ISO 27001 controls to safeguard customer account data from unauthorized access. This standard is distinct from specific technical security tools, focusing instead on the overarching management framework. Knowledge of ISO 27001 is valuable for professionals preparing for certifications like CISSP and CCSP.
