What does an Access Control Entry (ACE) contain in a Windows environment?

An Access Control Entry (ACE) in a Windows environment is a component of an Access Control List (ACL) that specifies the permissions granted to a specific user or group. The primary function of an ACE is to define what actions a user or group can perform on a resource, such as a file or folder. This includes information about read, write, execute, and delete permissions, as well as other rights associated with the specified user or group.

By establishing these permissions, the ACE helps regulate access control, thereby enhancing security by ensuring that only authorized users can perform certain actions on the system. In the context of access control, understanding the specific permissions outlined in an ACE is critical for effective security management in a Windows environment.
