AU-1 requires organizations to develop, disseminate, and periodically review and update an audit and accountability policy and associated procedures that address the following:
Purpose: Defining the purpose and scope of the audit and accountability program, outlining the objectives, and establishing the organization's commitment to auditing and accountability practices.
Auditing and Monitoring: Detailing the types of events and activities that are subject to auditing and monitoring, including both user actions and system-related events.

Retention: Defining the retention period for audit records, including storage, access, and protection mechanisms to ensure their integrity and confidentiality.
Response to Audit Findings: Describing the procedures for responding to audit findings, including corrective actions and remediation plans.
Access Restrictions: Stipulating access restrictions and permissions for individuals involved in the auditing and monitoring process, ensuring that access to audit data is appropriately controlled.
External Connections: Addressing the audit and accountability considerations for external connections, such as those to cloud service providers or other organizations.
Review and Update: Establishing a process for regularly reviewing and updating the audit and accountability policy and procedures to address changes in the organization's environment or evolving threats.
Specifically, Per AU-1 of NIST SP 800-53, organizations are to “Develop, document, and disseminate...” an audit and accountability policy and procedure.. The keyword here is “document”, which means you need a policy and procedure for AU-1.
