Access Management is closely related to which other processes?

Availability Management alone is insufficient because Access Management's primary policy authority comes from Information Security Management, not availability controls.

Third-line support is a support tier, not an ITIL process, and has no defined relationship with Access Management in the ITIL framework.

Access Management is responsible for implementing the security policies and access controls defined by Information Security Management, ensuring only authorized users can use services. It also works closely with Availability Management because controlling who can access a service directly affects whether the service is available to legitimate users. Together these two processes define the operational and policy context in which Access Management functions.

Information Security Management alone is incomplete because Availability Management also has a direct relationship with Access Management in ensuring services remain accessible to authorized users.
