Which of these is NOT a part of user access requirements management?

User access requirements management focuses on ensuring that users have the appropriate level of access to services and systems based on their roles and responsibilities. Key aspects of this management include understanding the necessary controls and risk mitigation involving users.

Due diligence involves investigating potential risks and ensuring compliance with any necessary regulations or organizational policies, which directly supports user access management. User training and certification ensure that users are equipped with the knowledge and skills to use systems effectively while adhering to security protocols, thereby contributing to better management of user access. Age control and identity check are critical components that verify user identities and control access based on age restrictions or other criteria, which are also fundamental to access management.

Service pricing negotiation, however, falls outside the scope of user access requirements management. This aspect deals more with the commercial agreement and financial negotiations related to service provisioning rather than the operational and security considerations of managing user access rights. Therefore, it is the correct answer as it does not pertain to the management of user access requirements.
