Which of the following defines the level of protection in Information Security Management?

The IT Executive is responsible for implementing security decisions, not for defining the protection level required by the organization.

ISO 27001 provides a framework and set of controls for information security, but it does not determine what level of protection a specific organization requires - the business does.

The business is responsible for defining what level of protection is required for its information assets, because it understands the value of those assets and the acceptable level of risk. IT and security functions implement and enforce the controls, but the authority and accountability for protection requirements rests with the business. This is a core principle in ITIL Information Security Management and ISO 27001.

The Service Level Manager negotiates and manages service agreements, but has no authority to define information security protection levels.
