What is an Access Control List (ACL)?

An Access Control List (ACL) is a list of permissions attached to an object, such as a file or folder. It specifies who or what is allowed to access the object and what operations are allowed on it. ACLs are used to enforce security policies by controlling access to resources.

For example, in a network environment, an ACL might be used to restrict access to certain files or directories to specific users or groups. If a user attempts to access a file for which they do not have permission, the ACL will deny the request.

In the context of cloud computing, ACLs are often used to manage access to cloud resources such as storage buckets, databases, and virtual machines. Cloud providers like Tencent Cloud offer tools and services that allow you to define and manage ACLs for your resources.

Tencent Cloud, for instance, provides a fine-grained access control mechanism through its CAM (Cloud Access Management) service. With CAM, you can create policies that define who can access which resources and what actions they can perform, providing an additional layer of security and control over your cloud environment.
