**What is Access Control?**\
\
Access control is a security mechanism that regulates who can view or use resources in a computing environment. It ensures that only authorized users or systems can access specific data, applications, or services. In cloud storage, access control defines permissions for users, groups, or service accounts, determining their level of interaction with the resources (e.g., read, write, or delete).
In Google Cloud Storage, access control can be managed through Identity and Access Management (IAM) roles or access control lists (ACLs) to define who has access and what actions they can perform on the stored objects.
