Control 5.37, Documented operating procedures, aims to ensure the correct and secure operation of information processing facilities. Operating procedures translate security and operational requirements into repeatable instructions for administrators, operators, support teams, and users. They can cover system startup and shutdown, backup, restoration, logging, error handling, media handling, job scheduling, maintenance, incident escalation, access administration, and secure processing steps. Without documented procedures, operations become inconsistent and dependent on individual memory or informal practice, increasing the likelihood of mistakes, outages, unauthorized changes, or insecure handling. Control 7.2, Physical entry, protects secure physical areas by controlling access to facilities, but it does not define operational procedures. Control 5.35, Independent review of information security, assesses whether the information security approach remains suitable, adequate, and effective, but it does not provide the day-to-day operating instructions. ISO/IEC 27002 places documented procedures in the organizational control group because reliable operation requires governance, clarity, and repeatability. Therefore, option B is the verified answer.
