Final answer:
Operational logging refers to the recording of events significant for the operation of a system, tracking user activities such as logins and resource access, and is a part of the audit logs aimed at ensuring operational security.
Step-by-step explanation:
The question asks to identify how operational logging is different from other logging types. The correct answer is 'd) It records logs about user login, unauthorized access to resources, and so on.' Operational logging is part of the audit logs and it focuses on recording events that are significant for the operation of a system. This includes tracking user activities, ensuring compliance with policies, and forensics, which involves recording details like user logins, file accesses, and other actions that could affect system operations or security.
Option a), 'It facilitates service provisioning and financial decisions,' is incorrect as it more closely aligns with business intelligence and financial logging, which are used for decision making at the management level.
Option b), 'It is a part of security logging,' is partially correct but not specific enough as security logging can include multiple types of logs including operational, whereas operational logs specifically detail the ongoing operations within a system.
Lastly, option c), 'It concentrates on recording debugging logs,' is incorrect as this would fall under debug logging, which is used by developers to troubleshoot software issues and not specifically for recording operational activities from a security or audit perspective.
