Using a Privileged Access Management (PAM) vault to secure domain administrator credentials and enforcing role-based access control (RBAC) is the most comprehensive solution. PAM systems help manage and control access to privileged accounts, ensuring that only authorized personnel can access sensitive credentials. This approach also facilitates password rotation, auditing, and ensures that credentials are not misused or left unchanged. Integrating PAM with RBAC ensures that access is granted based on the user's role, further enhancing security.

Containers are a lightweight virtualization technology that allows you to package applications and their dependencies into portable units. This means that you can run multiple applications on a single operating system, reducing the number of operating systems and the associated patching requirements.

When conducting an audit of an organization's risk management program, the internal auditor should first review the policies and procedures. These documents form the foundation of the risk management program by outlining the organization's approach, goals, roles, responsibilities, and processes for managing risks.

An independent audit provides an unbiased assessment of the organization's controls, verifying that they are properly designed and operating effectively. Such audits often result in formal reports, such as SOC (Service Organization Control) reports, which are specifically designed to give assurance to stakeholders regarding the effectiveness of controls.

A Cloud Access Security Broker (CASB) solution is the most suitable option for securing an organization that has adopted a cloud-first strategy and does not have an on-premises IT infrastructure. CASBs provide visibility and control over shadow IT services, enforce security policies, and protect data across cloud services.
